Even as the VJ software market matures, it’s refreshing to see with releases like CoGe – that there’s still room for new players and perspectives. From deep in his East European code-bunker, creator Tamas Nagy was kind enough to provide a review copy and an interview.

Features

“CoGe is a semi-modular, Quartz Composer® powered VJ application for Mac OS X®, designed for real-time media mixing and compositing.”

So – aside from the usual playback and manipulation of clips, what distinguishes CoGe? At first glance, the VDMX-like modular framework is immediately obvious, enabling CoGe to be easily customised for different performance styles or needs. Of the modules available, of notable merit is the very easily used sequencer.

A comprehensive wiki outlines the structure and approach ( the rendering chain / how the modular structure works / various automations+ mappings etc ) / clip synths, and a useful forum is fleshed out with fans eager to push it forward (At time of writing, CoGe 1.2.1 was just released, with significant performance increases ( lots more FPS on HD clips).

Quartz Composer is also quite deeply integrated into the software, which makes sense – given Tamas has developed a whole range of QC plug-ins which can be used within CoGe – eg PSD Brushes  / PSD layers Textfile readers / Webkit ( rendering webpages within CoGe )Beat Detektor / GPL reader ( reads GIMP palette files ) / Mouse co-ordinates etc. As well as possibilities for integrating customised Quartz files and effects, CoGe allows use of  3D animation meshes (Collada .dae format) and flash files alongside any movies and stills used for mixing and compositing. Want to build your own CoGe module using QC? Tutorial – how to create a simple effect for CoGe with Quartz Composer. And yes, rendering is through the graphics card for maximum performance, and double yes – syphon is well integrated too, for easy sending or receiving video to and from other applications.

Interface

It only took a little while to adapt to the CoGe world, and what initially seemed quirky, now makes some sense. The interface elements are easily moved, re-arranged and intelligently grouped together using what CoGe calls ‘aligners’ to “arrange other windows together into manageable organizational ‘buckets’”. It might look a little ravetastic, but it makes for easy navigation and visual feedback while performing, and the sequencer action is great.

Overall?

A welcome addition to today’s VJ software library, it’ll be interesting to see if CoGe manages to continue developing in some interesting directions, given what is being covered elsewhere.

Requirements:

$US99 (custom + educational pricing also available)
A Mac computer with 10.6.7/10.7 or later with a dual-core CPU and at least 1 GB of Ram.

Interview with Tamas Nagy, creator of CoGe VJ Software

Given there’s quite a range of existing VJ software – what inspired you to build CoGe?
It’s a kind of funny story I saw a first vj gig in 2001 in a music festival, and I fell in love with that thing. Never thought about being a vj, I made music before, so I’m from audio land. Then, when I got my first Mac in 2006, and saw Quartz Composer and saw how Quartonian works, I just think I can do something funny_ – never thought about to make a commercial application, haha – with a kind of sync with the music, so just tried it. It was the early version of CoGe, called LovQC, haha You can find some test videos made with it on Youtube.

Then I spent more time on the software, added lots of new features, and with 2 friends we just created a VJ team Luma Beamerz and CoGe was born. Anyway, the first version of the app was a 50mb QC composition with just an interface, then I started to learn Cocoa, Obj-C, OpenGL and other stuffs - Vade helped me a lot with the GL stuff, so CoGe now is a “real” application.

Anyway, I never used any other VJ softwares, I just created my own for my own wishes: triggering different points of movie on beat, sequencing still images, etc.

So, I think the big difference between applications is the workflow, so it depends on how you, the user think about creating things. All VJ software has a bunch of same features, triggering files, change speed, colors, etc., the big difference is the workflow, so I think an artist will choose software which works like his/her workflow. For an other example, modularity is a great thing, but a lots of users happy with built-in features in apps and never thought about it can be different.

It’s integrated into your app quite a lot – but what attracts you to Quartz Composer?
The great thing with QC is very easy to learn the basics and use for non-programers too, you shouldn’t be a coder to do a simple image rotation for example. On a developer side, the system integration – using QC stuff inside an application is easy – is a very important thing in my opinion.

It also have a lots plugins, and great media handlers, so a lots of things is possible with QC – basically, CoGe just connects QC stuffs under the hood, nothing magic.

What impact does Syphon have on how developers might approach VJ software today?
I think Syphon has a lots of potencial and its a very great stuff – connecting different sources into other applications is really opens some doors, just think about “sending” images from Max and Processing, and you can mix them in CoGe in a very simple way. That couldn’t be possible before Syphon.

Do you have opinions about whether VJ software should provide more advanced audio controls? And sequencing controls? Or is it better to sync VJ software to something like ableton?

I really like sequencing, using clips and stills in sequencing can provide really good things. With audio controls you can have some fun, but the really good choice is syncing with an audio host if you would like to make real AV things.

What are the challenges of making a good performance interface?
It depends on your workflow and what you wanna do in the performance. I recently just using 3 layers with a lots of media presets and some simple effects. If you using a lots of things the new Aligner stuff helps you to make smaller groups on the screen, I think its a very important feature.

What are you happy about in CoGe today?
CoGe 1.1 release makes me happy, i got a lots of positive feedback on it, and saw some really nice things created with CoGe. Also happy because i have a lots of ideas for the future

Thanks Tamas!

Reasons you might find yourself wanting to read this very long but very awesome Raquel Meyers interview:

- Because you love 8bit graphics and people who push them to their limits

- Because Raquel makes rad stuff ( eg her recent DVD of ‘fighting washing machines and killer lego ducks’, full of videoclips, remixes and collaborations with chiptune musicians and pixel pushers – Useless Yet Crucial).

- Because you want to find out about her ascii storytelling experiments with the C64 shredding musician Goto80.

- Because you love reading about how artists wrestle with their processes.

- Because you need a crazy and wonderful collection of visual links in your day.

Who knows, but I hope you enjoy these responses as much as I did. Thanks Raquel~!

- What’s inspiring you these days?

At the moment I am experimenting with storytelling and text-based graphics like Ascii, Ansi, Petscii and Teletext with Goto80. I’ve changed both the tools and the purpose of what I’m doing during the past months. I guess what I’m doing now is formally similar to text adventures, cartoons, silent movies, text art, demos…

I’ve been mostly inspired by animations and short movies from the 20th century, like “Little island”(1958) by Richard Williams or “Cowboys”(1991) by Phil Mulloy; and also, children’s books. Because of the brutal style of the “Simple storytelling”, the combination of a drawing plus a short phrase who builds a full dream up. This one makes me think about 2 frames animation, and how something simple it become even more brutal, especially working with the C64.

In the case of the short movies, the animation comes before the music, so the video is not the slave of the music (music video style). Sound effects increase the tension and the verve of the animation, and could be use in a shorter way like an interlude, or something longer. But the main thing is the story behind it, whit out it you cannot go further.

A cinematic new age terror is coming!. It operates in text mode, only using characters of the Commodore 64 and Amiga. This applies both to the graphics and the music.

[[ EDIT: Terror is now live - witness “2SLEEP1”, a "66-minute playlist of audiovisual performances in text mode, designed to make you fall asleep. Press play, go fullscreen and lie down. Made by Raquel Meyers and Goto80." screenshots below:]]

- What hardware and software do you use to create your animations?

I use several computers. A C64 with Letter Noperator and DigiPaint. An Amiga 1200 with DPIV, Brilliance, Prism and also an Amiga 600 provided by Archeopterix. A PC and Mac, with Flash, Photoshop, video editors and the (unreleased) petsciibrush software made by Linde. Soon I will add a Teletext device.

I’m not a gear freak. I don’t really care about the tools. I used to work primarily with Flash and Photoshop, which was a pain in the ass for the things I was doing. But I still liked it. Now I use old things (Amiga and C64), and that’s also quite painful sometimes. So to answer the question – I blend old and new technologies. It doubles the pain!

I am not a purist, I am a blender.

- How much of your creative process is defined by the limitations of such technologies?

I prefer to talk about possibilities instead of limitations. I think the technology is not the limited one, is the human behind it. It doesn’t matter how old or new the technology is, there is always something new to discover and learn. It’s not a such a big thing to use old technology, it doesn’t make everything more special, different or better. In my case, I use it because I like it.

But the things I do in Flash are different from what I do on C64. So the process is different. But I don’t really like to think too much about those things.

- Is there some cut-off line for retro computer graphics, where they are too new for you to use? What is it about 8-bit that manages to sustain appeal for you?

At least not for me, I’m not interested in the retro version of 8-bits, so I don’t think about if something is too new to use or not.

I remember playing pong with my brother in the TV console, meet my friends at ‘ la sala de máquinas’  and how I had stuck in my head every night before going to sleep the Tetris song. I grow up with arcade games and graphic adventures but, it wasn’t until 21 century when I discover a C64 music archive on Internet, and all these memories becomes something else because of the music.

It wasn’t a revival, it was something else, the imaginary frame in my head that before was a picture now become pixels looking for to be animated.

I don’t really know, but I think what keeps my interested in 8-bit is the brutalism. Big blocky objects, raw animation techniques, few frames, cuts, etc. I think it’s better if the animation method is brutal, because then it contains so much more than with some detailed video where there’s less room to think on your own.

- What do you find interesting about making live visuals versus production work?

A Live Performance is always open to improvisation and mistakes, meanwhile production work is always under control in the time line. You can rehearse or planning live visuals but at the end you don’t know what is gonna happen. Is really fun put yourself in a non control mode, keeps the spark. And since I don’t really use VJ-software to perform, it’s always a challenge.

- What work have you done on combining and compositing 8-Bit and recorded video together?

As part of Entter (2000-2007), the video clip Fantasy’ by Goto80, and ‘Dietetic Music’ by Eat Rabbit with graphics from Otro. Both of them were my earliest works in the 8-Bit, 2004 and 2005. Based on video recordings and post-production. In latest video clips, I mixed photo animations and graphics like the ‘Droidduck’ by Psilodump (2010), ‘Pink Snow’ by La belle Indifference (2010) and ‘Polybius’ by tr1c3 (2010), based on the main live cinema project ‘Polybius’ with Goto80. Also parts of the vj set contains video and graphics mixed. The reason of that is because my first background was Analog photography. I started when I was 14 years old, with black & white films and experimenting in the lab. The first thing jumping in my mind is always a static picture, a frame. My work is based in the movement or animation of such frames.

- Can you describe your AV set with musician Goto80, Polybius? ( and your aims behind it?)

Polybius …. the idea came from a post I read in my brother’s blog in 2007. The post was about an urban myth about an arcade game from the 1980s (Polybius) that created a sensory and cognitive deprivation in its users. So I started to talked with Goto80 about it and how much I would like to do something with it and with him.  The basic idea was explode the links between fiction and reality by encouraging a loss of senses. But it was not until 2009 when the french collectif ‘Homemade’ invited me for a 2 weeks residence at Le maki (Angoulême, France) when the Polybius experience become something else tahn talks. I developed there a first 20 min version, using a ‘cute’ character like a rabbit to hide my really epileptic and apophenic purpose, and Goto80 was working in the audio online from Sweden. The project was officially presented at the Cimatics festival the same year.

In the beginning of the 2010 we develop together in Berlin the second version who combines line vector aesthetics with video manipulation and 8-bit technology to induce feelings of apophenia, amnesia and panic. The Polybius experience – invented and created by us in the form of a white rabbit with a sectarian-politonic-track to be stuck in your head.

[[ Tangent alert! See also: previous 'C64 Shredding interview with GOTO80', and 'Cappadocia Skies' - a clip I'd made about a hot air balloon ride, with music by one of GOTO80's aliases, Extra Boy. ]]

- What’ve been the challenges of developing that, and what has worked or not, when performed live?

One of the biggest challenges was working in the distance via Spain-Berlin-Sweden thought Internet. Because we build the project together from the beginning and sometimes was really difficult to define and create the content without being in the same place. When we presented the project at Cimatics, we realized we need to meet physically to develop a second version and special place to performed it, out of the club experience. So in the beginning of 2010 we meet in Berlin for a week to prepared the second version, because we were invited by the PlazaPlus Festival in Eindhoven NL to performed it in january. We made a special pass before for the visualberlin collective at fh.meppen (Berlin) to test the extended version of 32min and got feed-backs from the public. The third and last version is pending, who icludes the physical game and an installation. But for this we need budget and maybe a residence to develop it. It’s one of the most complicated projects I have ever done.

- To what extent are you able to adapt the visual side of that with each performance?

My set is manual. To be able to adapt to whatever happens in the live performance. Before I was only using one laptop running an aplication who host all the visual content (graphics, animations, videos …) controlling by hand with the keyboard. So the rhythm was build in the way I click on the keyboard and load the different content. Now I’m working in a new set, who consists in a C64 and an Amiga, still in process, so I used the laptop as extra support with the same technic. A video mixer is used to change the sources, but there is not so much effects involve. The thing that takes more time is making all the animations, graphics and videos. I only used my own material, and always try to made a special set for each performance.

- Have your computer / animation processes ever entered / filtered / affected your dreams in any way?

Yes it does, because I listen so many times the songs when I’m working with it and also I dream with the animations. But ‘Polybius’ was something really insane, I had one of the tracks stuck in my head, like a trance mode to my own sense deleting experience.

- At the ‘Artists-Who-Inspired-Raquel Meyers’ Award Ceremony, who gets the following awards? 

- Visual artist who most steps outside the echo chamber of contemporary styles?

Nam June Paik, the retrospective exhibition ‘The Worlds of Nam June Paik’ in 2001 at Guggenheim Museum Bilbao I saw, put him for me in this category, like the “Magnet TV”.

- Visual artist with the most exquisite and hard to understand technique? 

Poison, I know the technique, but is not enough, because even if you use the same software you cannot have the same results. As PETSCII graphician was really impress how he made ’2frames’ animations and graphics for the C64.

- Visual artist who best gets under your skin? ( transcends technique to grab your emotions ? )

Otromatic, he is my favourite 8 bit graphician. He become one of the reasons why I start to make Lo-fi graphics and animations.

- Best coherent, integrated audiovisual act?

Gangpol & mit. Really impressive performance, one of my favorites. I really enjoy the animations.

But wait, there’s more:

This is something really difficult to do because inspiration doesn’t come only from visuals. They are so many things involve in this process. Here there is some of them, older and newer inspirations:

- Visions of Frank. The dreamlike world of ‘Frank’ a comic by Jim Woodring converted in animations.

- Jan Švankmajer and his surreal animations like ‘Meat Love‘.

- Professor Balthazar, a cartoon series for children, created for television by the Croatian animator Zlatko Grgić. Watching this as a child build a surreal imagery, who come up when you become older.

- Poison, C64 graphician. The ‘Notemaker Demo II‘, all you can do just typing characters.

- Russian and Eastern Europe cartoons (like Suur Toll- Estonia), even if we don’t share the same language, I can feel the eerie atmospheres.

- Bernd and Hilla Becher and their industrial buildings photographies. The motives of my early photographies were the factories buildings from my hometown at night when I was 15 years old.

- Kohei Yoshiyuki and his soft-core voyeur’s manual.

- Stalker, film by Andrei Tarkovsky (1979). This one change something inside me in the 90s.

The Gertrude st Projection Festival

This grows nicely each year, transforming lots of shopfronts and buildings in Gertrude st for a week. Above, a nicely mapped facade by Olaf Meyer. There was apparently a pretty good opening night party of projections, which I missed due to projecting elsewhere for the Scattermusic label launch party. Below, a mapped sculptural piece by studio neighbour, Kit Webster, alongside a fancy dress store where peering into a camera projected your face onto that of a shopfront scuplture. (More projection photos).

Inherent Vice

The National Gallery of Victoria convinced some local comic artists (Pat Grant, Mandy Ord, Michael Fikaris and Simon Hanselman + more) to transfer their private studios into the the public spotlight for a few weeks. The results included a zine fair, 24 hour comic jams, tents and drum-kits set-up in the studio, drawing lessons, an Inherent Vice tumblr and a steady stream of bug-eyed kids and adults wandering through. Check the article in the Australian, or the artist interviews on the Age website.

Winterpark Exhibition of Artworks Inspired by Album

I went to this because local video artist Lucy Benson, now in Berlin, had a hypnotic piece in it - ’Gotta Sleep now’, but my camera phone couldn’t really capture her shimmery work. Below, a sculpture that nicely incorporates video and little people. Can’t figure out from the event page who actually made it though, maybe you can. Nice idea for an exhibition, and great to see the different interpretations of the tracks.

Nosaj Thing Live at Kensington

Hadn’t even heard of the warehouse venue Nosaj was playing at – Revolt – and arrived to a building crazily decked out with technical and bar infrastructure, including pyramid mapped video sculptures by Kit in the distance. Came complete with a 90s black light chill out room. The Nosaj set was great, the rest of it got a bit wonk-saturated after a while.

Audiovisual Performances

Zeal and Time Shield have been steadily honing their AV performances around town, and recently Zeal invited me to do an AV set at Bar Open in support of his threepiece Virtual Proximity (see above). I was quite happy with this set, playing with some ambient music, ocean footage and quartz patches in VDMX. Elsewhere, Sampology came down from the subtropics to do an AV show, and Naysayer and Gilsun more recently launched their new AV set. There be audiovisual things happening. (Often at Racket – first thursday of each month at Miss Libertines in the city, and Plug N Play – last Thu of each month at Kent st bar, Fitzroy. )

MÖBIUS by ENESS

MÖBIUS from ENESS on Vimeo. This ‘collaborative stop motion scuplture’ was the brain child of Benjamin Ducroz, an extension of his work with time lapse and physical sculpture – this time using lots of help from public volunteers in rearranging the pieces over and over throughout the day.

And yeah, Melbourne International Animation Festival and the 60th Melbourne International Film Festival just whipped past. Quite a few delights and surprises in there. Will bundle together a short post and some links to the films I liked in a while. This’ll have to do for now. Springtime!

End result: Lots of fun – and a new set of challenges to deal with. Spatial composition with video is getting easier and easier, and as we outgrow the novelty of seeing buildings lit up / architectural deconstruction by light, there’s such ripe terrain to explore with today’s software. And as the barriers to entry continue to lower, it’ll be the imaginative approaches that prove most successful.

[[ Oh yeah - and that video - not a manifesto for spatial video by any means, just some example snippets from a fun night with the Scattermusic Sound System.. still getting my head around how this can all work well. And there be photos too. ]]

After doing live video for 2 shows there last weekend with the Gotye band, I can add to that list:
- It is a rabbit warren under the sails.
- The salad sandwiches in the green room are very ordinary.
- The elevator under the concert stage is faulty (I was trapped there with a weary tech guy for 5 tense minutes.. )

I got roped in to do live video for Gotye’s tour for his just released Making Mirrors album, which has accompanying animations for most songs. There’s some pretty nice work amongst it – I’ll have to do a follow-up post soon with links to all the animation houses. For me, my work is mostly editing and formatting to suit the main screen and 2 vertical side screens, then while the band plays – triggering short sections of these clips to ensure the right visual moments are synchronised with the band playing live.

Despite an almost comical list of headaches – long fog delays at Melbourne airport, animations arriving at the last minute, software quirks, a compressed set-up time, hardware quirks, that elevator(!) and so on – the first shows of the tour ended up running really well. Having a crack team of musicians (and tech folk) definitely helps in that regard (including Tim Shiel aka ‘Faux Pas’ beside me onstage). Below, the band and my hard-drive covered laptop during sound / vision check at the Opera House.

And the VDMX interface spreading its wings up on the screen briefly during rehearsal.

And once again, with people.

The Graphic Arts festival

Awesome choice for tour opener – showcasing an album and animations within a festival dedicated to comics. Graphic Arts had some great highlights this year:

- Jim Woodring, the author of FRANK, did a pretty mind-expanding talk on DEATH-CAKE apparently, and fantastic inking masterclass (attended by comic-friend Gregory Mackay (Francis Bear)).

- Tekkon Kinkreet - fantastic animated film – with accompanying live soundtrack by Plaid (Warp) + Fourplay (strings) + Synergy (robotic rubber limbed percussionists). Really luscious sound, really luscious film.

- Silent Comics – a series of comic panels projected while musicians provide a soundtrack. This included sound foley artists, Captain Beefheart-esque carnival bands, Seekae, Wally from Gotye in splinter-sample mode, and probably nailing it best, Plaid. Great idea for a session.

- Scott McCloud – from ‘Understanding Comics’ (also used as a multimedia bible in explaining media and visual storytelling concepts ) did a great one hour presentation, which harnessed visual support material as effectively as you’d hope a guy like him would. Lots of interesting points, though I found myself laughing at his interface observation-  ”Why does Tom Cruise need a glove to do all that in Minority report?”. He also ended with this pretty funny reading of a scrolling comic that involved monkeys mutating into progressively crazier proportions.

- Pete Kuper – aka the guy who did Spy Vs Spy from Mad magazine.

- An assortment of Aussie comic artists doing talks and workshops – including Mandy Ord, Pat Grant and more.

Sadly Robert Crumb wasn’t part of the mix – but I was amused to learn from the Festival organiser about the communication process they had – “Yes, Robert uses email, but that involves….” –  his assistant scanning his recent emails, printing the interesting ones, highlighting the relevant bits, cutting those out and putting them in an envelope and mailing them to Robert, who replies on the back with his pen. When he’s around.

Have been doing some experiments recently with Troy Innocent, involving laser cut characters, everyday scenes and projection mapped video. We’re trying to figure out what works well for us, with an eye to fleshing out something some kind of developed work later. Troy has access to a laser cutter at work, and obviously the attraction there is to play with the unique levels of intricacy that a laser cutter allows with materials such as plastic and thin plywood. Taking that a step further, we thought it’d be fun to develop some simple low frame animation loops with these physical characters and record them moving about in stop motion. We’ve done some simple tests outdoors which worked well, surprisingly popping to life when played in sequence onscreen, and most recently we tried an indoor shoot, which gave another chance to test out Madmapper.

Re-Routing Video in 2011

First up, the whole routing video clips between video applications thing, enabled by Syphon, is really fantastic. For me, this means VDMX to Syphon to Madmapper to the projector. Manipulate video in your preferred real-time software, then at the end of the chain remap this video onto what Madmapper calls ‘surfaces’, creating, positioning and reshaping as many of these surfaces as you like. This makes sense and so far the addition of running Syphon + Madmapper alongside VDMX hasn’t seemed to dent the performance of VDMX at all. That might change with more complicated projection mapping – we’ll see.

Some Madmapper Observations

As seen above, the Madmapper interface is minimal and intuitive, and this helps mapping happen super quickly. For our test mapping onto some paper skyscrapers, it was a simple process of selecting which part of the video to be sent to a surface, then clickdragging the corners of the virtual surface until it the video filled the actual surface of the paper skyscraper in front of the projector. Total time to line-up video on the sides of 3 buildings? About 5 minutes. This is a very simple example, and possible with other existing software – but this software certainly makes the process a breeze. Am going to post a full review of Madmapper soon, and discuss some of it’s strengths and weaknesses for dealing with more complex scenarios. In the meantime, it’s worth noting that although it’s pitched as a solution for reconfiguring 2D imagery onto 3D shapes – Madmapper’s ease of use also makes it a very attractive option for just even compositing imagery within 2D environments. From the close-up below it should be evident how straight forward it is to select portions of video, and quickly composite this into desired shapes.  More laters!

Now that I’ve finished marking all of the respective assignments from classes at RMIT and Swinburne, am looking forward to biting properly into a few long neglected creative projects / overloaded bookshelves / learning curves etc. And that overdue skynoise overhaul so it better reflects the 2011 web and myself. Next up though, a video island adventure in Sydney harbour.

As part of the 2011 Underbelly Arts festival, I will be creating video projections to accompany long time audio wizard collaborator Dan MacKinlay, James ‘Dubtable’ Nichols ( that’s him in the photo), and Sarah Harvie whose specialty is inflatable sculptures! We’ll be doing this as ‘Pattern Machine’ in the space photographed above, which is one of the ancient ship building rooms at Cockatoo Island in Sydney Harbour. Pattern Machine has a tumblr and a twitter account, where we’ll be documenting our preparations and experiments, and also has a festival page, alongside all the other festival artists.

This year’s festival was pitched as an island residency for developing some works in progress. Looks like it’ll be quite an interesting collection of projects, with many artists practicing / building / tinkering on site in public view, followed by a performance  and exhibition day on July 16th, showcasing what has been explored during the residency.

For our part, the work in progress will mean explorations into location sampling and weird algorithimic audio with Super-Collider (eg “New No New Age Advanced Ambient Markov Music Machine” and attempts to intertwine inflatable tendrils around the machine relic within our inherited room. Pixel-wise – I’m hoping to do some projection mapping experiments onto that machine relic, re-animating it as it were, in real-time response to the sounds happening, and similarly try to create some kind of responsive visual designs on the inflatable structures. Aside from that, I’ll also be testing out a triple screen external graphics card ( matrox triple head 2 go ) to experiment with simultaneously projecting various scenes onto the wall behind the machine and inflatable sculpture. For the scenes projected on the wall, will be playing with some simple responsive graphics and some filmed / composed sequences of various events / stop motion / locations from around the island. My tools of choice : VDMX + Quartz Composer, with Madmapper for the projection mapping (Madmapper review coming soon).

Below, James and The Machine, moustache not to scale:

June 5th, 2011.

Due to a weird Sydney Opera House ticket mix up – I ended up at YO GABBA GABBA live this weekend – instead of the planned pilgrimage to Chris Cunningham’s triple screen live cinema assault. Priceless. Etc etc

More laters…

Earlier Quartz Wrestling delivered a splitscreen effect which took any clip playing in VDMX, and replicated it 9 times to provide something like a video-wall. It also customised a few of the Quartz based VDMX transitions, and identified a new range of problems when creating in Quartz. After some more noodling, and helpful tips from both Dan Winckler and Joris de Jong (hybridvisuals.nl), I managed to solve some of these problems, and custom build an effect I’d wanted (attached below).

1. How to select a custom anchor point in Quartz, for rotating an image or video?
The idea here was to be able to generate rotations from a corner, or from create arcs of rotation, with the rotation centre being far below the image. None of the various Quartz patches I could find seemed to have an ability to adjust an anchor point.

The solution? “Reposition the clip so what you’d like to be the anchor point is in the center of the screen, then place it inside a 3D transformation patch, and use the rotation Z property of that patch to rotate it.” (via Joris)

Understanding three dimensional space is best done when you have at least a slithery grasp of 2D first, and it took me a while to figure out why the width of a quartz patch always seemed to fill the screen when it had a value of 2.

Welcome to the Quartz Composer coordinate system:

The width of a Quartz Screen is always 2, because Quartz treats the centre as 0, and gives the left and right borders of the screen the coordinates of  –1.0 and +1.0. The coordinates of the top and bottom borders depend on the screen aspect ratio (AR). In the case of a 4:3 aspect ratio, the values at the borders are +1.0 / AR = +0.75 and –1.0 / AR = –0.75. ( From the Quartz Guide written by Apple’s basement dwelling engineers. See also: Quartz Composer User Guide (PDF))

Ok. So rotating a video and changing the anchor point.

The 3D transform patch that Joris suggested placing the clip inside, is a macro patch (which in Quartz have square borders, unlike the rounded corners of most patches). Macro patches can be created as usual in the Quartz editor window, but can host subpatches within them (after double clicking them. Clicking ‘edit parent’ takes the user back up the hierarchy to the editor window containing the macro patch). Below, the anchor patch with the 3D transformation macro patch:

Some notes from that screenshot – the viewer window is showing the combined result of 3 layers – each of which is contained within the macro patch. One of those is an image of red manga speed lines (set as the top layer, with blend mode set to add), and the others are a VDMX input, and a mask image to frame the VDMX input. As you can see, the centre of the image is black – because there is no VDMX input at the moment. Creating quartz patches for VDMX seems to involve a weird workflow of using say a webcam ‘video input’ while building a patch, and then swapping over the ‘VDMX video input’ when saving, then testing to see how it works in VDMX, then going back to Quartz and reconnecting the webcam and making adjustments, before reattaching the VDMX input and saving again.

Previously I’d only been working with Billboards in Quartz, which helped avoid 3D space – billboards ’render a quad positioned with 2 coordinates and which always faces the viewer’. I’d been routing clips and effects in patches to a billboard, which generally meant  the viewer was filled with my video. So to create this anchor patch, I put a Billboard inside the 3D transform patch and set about trying to adjust the subpatch. This didn’t work, and Joris explained why:

“Billboards don’t work in 3d space, so you need to work with sprites. Sprites are basically the same as a billboard, but you need to do some of the height and width calculation yourself. I’ve attached an example of how to offset the anchor point, and how to size the sprite correctly based on different input images.”

The example included the image dimensions patch, which “gives you access to info about your current rendering environment (resolution in pixels and QC measures). You can then use the Math patch to further process this info to fit your needs. This way, when your output changes from 4×3 to 16×9 for instance, your patch will update accordingly. The QC coordination system takes a bit of getting used to, but using the RDD patch to keep things dynamic is a good practice.”

Rotations applied to the 3D macro patch, transform all of the sprites inside it, so I figured I’d try and add a few sprites and create a layered result that could be rotated at will within VDMX. Clicking on a sprite patch reveals in the settings, blend modes of ‘reveal’, ‘add’ and ‘over’. And I figured PNG images with transparency, or videos with alpha channels would allow masking and compositing within Quartz. After a bunch more trial and error, some blending tips via Dan came in handy:

“PNGs with transparency: alpha channels aren’t respected when the Blend Mode of Billboards and Sprites is set to ‘Replace.’ Choose ‘Over’ or ‘Add’ and you’ll see your black backgrounds disappear.

Blending in general: The drawing order of renderers (layers) is determined by the little 1,2,3,n… dropdown box at the upper right corner of blue Renderer patches. Make sure your Clear patch is set to 1 (first/bottom).

Other blend modes: if you type ‘blend’ in the Library search box, you’ll see all the Photoshop-esque blend modes. Again, it’s not like a video mixer — play with the patching order (the Image and Background Image inputs) some. Better yet, make your compositions into plugins and do your mixing/blending in VDMX or another QC host app!”

And eventually, I ended up with this custom masked anchor rotation effect for VDMX – which composites whatever video VDMX is playing, underneath the speed lines, masked by a circle, into the centre of the screen and allows real-time control rotation. Which is really satisfying – custom tuning an effect for a particular purpose. I’ve included the patch below – click on the image sources to replace them with your own, play around with the 3D transform values to create your own rotation variants, and for any parameters you’d wish to access inside VDMX, publish the relevant inputs and splitters.

Download the patch (with inbuilt masks. 2.3 mb) here to play in quartz, and here to use in VDMX ( place it in your QCFX folder and it should show up).

Thanks again to Joris and Dan, who provided insights at just the right times!

Measured in net years, Wacom’s Intuos 4 graphics tablet is already a sleek, sleepy dinosaur, having been released in 2009. On the other hand, given today’s infatuation with touchscreen tablets and their gestural capabilities, it’s worth reinvestigating what benefits a traditional graphics tablet can offer.

Straight Up
Touchscreen tablets are great media browsing devices and provide lovely accessible software interfaces. No argument there. But when it comes to fine, detailed control, touchscreen tablets can only manage the tiniest fraction of a graphics tablet’s input sensitivity.

But wait – your friend has paid money to a kickstarter project which will be sending them a newly designed conductive texta pen for use on their ipad. Or they’re getting a Bamboo stylus for the iPad. That’s awesome, but it’s still effectively only fingerpainting resolution. Fun to apply direct to the screen (and much cheaper than Wacom’s direct to screen Cintiq Interactive Pen Displays), but still very limited when it comes to precision and detail.

And when it comes to precisions, the Intuos 4 has the highest sensitivity of any graphics tablet available today (5080 lpi resolution, and 2048 levels of pressure). It also comes with a precision pen (60 degrees of detetctable tilt), customisable shortcut buttons and a radial menu system (think ipod) with LED labels (visible in the photo above). So when you’re ready to shift from fingerpainting little animated flipbooks on your touchscreen tablet, to creating highly detailed worlds, the graphics tablet is your new best friend.

Special Features
I’ve owned an Intuos 2 in the past and was skeptical there’d be much difference, but a range of carefully implemented design changes make the Intuos 4 noticably better to use. The physical shape has been slightly adjusted to feel more comfortable, the USB cable can be attached from 2 locations to suit left or right handers (there’s also a wireless Intuos option), the pen has been made more ergonomic (it actually feels better), and the express buttons and a touch ring have been nicely integrated beside the drawing surface, for easy access to whichever software menu items you set them up for (on a global or application by application basis).

What really brings it all together though for this version of the tablet though, is the addition of LED labels that accompany the express keys and touch ring, as these lit up labels help enable easy navigation of complex customisations and menu layers, which makes it possible  to avoid your keyboard for long periods of time when manipulating software.

The four mode Touch Ring for example, can be used for accurate and intuitive control of actions such as scrolling, zooming, changing brush size, rotating the canvas, flipping through layers, and more. Click the ring to select a mode such as brush size (which is LED displayed), then slide around the ring controller to change the actual size of the brush. Use one hand to modify tool properties, while the other continues on the tablet with the pen. It’s an effective combination, and can be customised to suit whatever combination of onscreen tools and menu items you need.

Whether seeking an alternative to the mouse or just seeking to avoid RSI, the precision and comfort of the Intuos 4, along with its newly lit-up custom shortcuts, make it an attractive input device for those wishing to manipulate their graphics, animation, audio or video software. Well worth a look!

Requirements for Intuos 4 tablet (USB Version):
Windows: Microsoft Windows XP with Service Pack 2 or 3 or Windows Vista
Macintosh: Mac OS X 10.4.8+
Cashola: The Intuos 4 Medium is $449 from buywacom.com.au

And Then:
More babysteps with Quartz. I set about trying to make a split-screen effect quartz effect which would replicate any video 9 times within the same screen. (This was to fulfil a request for someone who wanted me to alternate between fullscreen and 9 videos on a video wall made up of 9 screens, where a hardware matrix switcher would usually be used, but couldn’t be on this for some reason.

Over at the quartz section of Vidvox forums, Vade answered my query with:

“Can’t you use 9 billboards and make them 1/3rd the size of the screen and position them accordingly?”
and even offered up an example file.. http://vade.info/9.qtz

Bingo! Coming from traditional video editing land, I hadn’t even been able to grasp that creating a new billboard effectively creates a new image that can be composited. So then, loaded with new brain juice, I set about transforming the patch so it would work within VDMX.

There were a few barriers:

1- For parameters within a Quartz patch to show up as visible, adjustible parameters within VDMX, a process called ‘adding a published input’ needs to be done. The above quartz patch was set-up to take a webcam input and replicate that 9 times. This needed to be changed to a ‘published image input’, which would mean when loaded as a VDMX effect, it would take any movie playing in that VDMX layer, and apply the replication and compostion effect to it. The adding a published input process is documented on the VDMX wiki.

2 - Although the webcam split evenly into 9 screens, when taken into VDMX the 9 clips had plenty of overlaps. This became a tedious process of working in quartz with webcam version, dimension mode on auto-height, adjusting the input parameters for each billboard a certain amount, then adding the VDMX input back in, importing to VDMX and testing what it looked like now. (If anyone has any advice on making composition arrangement in Quartz less painful, love to hear about it! ). Eventually, I managed to make a VDMX effect that can quickly turn any 16:9 clip into the desired 9×16:9 clips, in a 16:9 screen.

And here it is: http://www.skynoise.net/quartz/9screens16_9.qtz
( Dump that into your Quartz FX folder of VDMX and it should show up as an effect for any layer ).

Moving Along:

The transitions used in VDMX are available as quartz files to play with in the VDMX composition mode folder. Open them in Quartz, saving under a new name and playing around with them makes it fairly trivial to make new transitions. If you add something else useful from Quartz to them, or wish to have real-time access to any of the parameters of the transitions ( eg opacity / angle, etc ), these parameters can be published as inputs using the above methods, and then they show up as VDMX friendly parameters that can be mouse dragged or audio synced etc.

A Next Batch of Quartz Problems:

Planning to work through these over time, but figured I’d list them here, in case any pointers fly in…

- Is it possible to select an anchor point for rotating a clip in QC? (So that for example, a point well below the screen could be used as the centre of a circle that passed in an arc across the top of the screen.) I found the anchor.qtz example patch which seems more related to anchor points in HTML pages, but maybe there’s a way of using it?  And the ‘Image Transform’ effect has a rotation parameter, but no adjustible anchor point?)

- How can a slider transition be adjusted so that both clips move in sync, not just one sliding in over the other?

- Related to the slider sync – how to do seamless tiling? Am guessing once the sliding is figured out, use mirrored images at the edge of an image, to enable a seamless horizontal or vertical scrolling loop?

- Is it possible to include video masks on a layer, not just image still masks? Is it possible to use masks that effectively create blank / alpha channel space around pixels in a layer?

- Some day : separate photoshop layers with adjustible depth of field blur in sync with z depth?

- Some day II : sliders that create exponentially smaller (replicated) slices of a video.

- Some day III : more sliders, that create puzzle slider type FX, but with adjustible zooming and scaling on the pieces – so they stay the same puzzle size, but are more or less zoomed in.

So if you’ve got any advice, suggested reading / plug-ins etc about any of the above – please get in touch.

UPDATE : The Syphon app (mentioned below) routes video losslessly between video software using the graphics card, and now the Syphon recorder can record the output of these apps. Send feedback, flowers to Vade and Bangnoise.

Free screen capture options:
PC – Camstudio /, Mac – Capture me. And Vade’s free screen capture tool (mac) allows you to ‘capture your entire desktop, or a portion of it, to an image and further process it within Quartz Composer or supported host applications. This can be used to sample other application’s windows as a source input for post processing, texture mapping on to models, etc’. Which means in practice, VJs can use it to grab screen content (eg games, DVDs, web, cams, other software output – whatever you can see on the screen ), and then process this feed in VDMX however they like.

More Broadcasty Tailored Options
Snapz Pro (mac:$69) and Screenflow (mac$99) offer simultaneous camera, microphone and audio capture as well as screencast options such as highlighting the mouse, key commands or certain windows.GrabberRaster (mac) allows sampling of any portion of the Mac screen for use as input for Quartz Composer, or as virtual camera input for QuickTime Pro, Skype, CamCamX or other QuickTime-compatible webcam software. $99 bundled with a bunch of other cam FX.

Sampling VDMX with Syphon and BoinxTV

Boinx TV is a custom video application for live mixing and recording of presentations / tutorials / news stories etc. Syphon (mac) not only samples the screen – but allows real-time sharing of full frame rate video or stills, with other applications. Future versions of Syphon are likely to have built in recording options. For now though, combining Syphon with Boinx, Berlin’s @fALk_g and Leon von Tippelskirch, one of the Boinx developers, came up with an effective way for recording VDMX – and it works in HD!

This could be a great workflow breakthrough for people creating motion graphics or doing compositing or visual effects. Being able to easily improvise with VJ software and midi controllers will never replace some of the detailed micro-level animation and editing done in dedicated editing and compositing software, but it should make it much easier and more fun to create certain kinds of clips for layering / visual effects / remixing and re-use etc. And who knows what kinds of new workflows (playflows?) and processes might follow from there..

Instructions via @fALk_g:

- Install Syphon and Quartz Syphon Plugins (free), and BoinxTV Home Edition ($49) ( see Boinx review)
- Activate Syphon Output in VDMX (beta 8 via vidvox.net)
- Load custom quartz project into BOINX, that can tap into the Syphon source. (download file 82k)
- Hit record. The custom project records with the Apple Intermediate codec (for best balance of quality and performance), but can be adjusted within settings. For best quality and framerate, Falk recommends playing clips from one drive and recording to a separate drive.

Bonus speed gain: Because Syphon is feeding video to Boinx, you can deactivate VDMX Output and use the Boinx 2nd monitor output to view your VDMX mixing – it actually seems to improve performance / frame rate.

The above instructions and file worked fine for me, but I haven’t really tested how far it can be pushed (eg lots of layers and CPU heavy FX in VDMX, while recording HD to a drive). Fun times ahead.

And finally on the screen capture front – a shout out to 9-eyes.com – an incredible collection of unusual moments captured by Google Street View, photographing every road in the world – For The Surrealist Win!

Vat Ist?
Video mixing software (mac only) set up for easy, intuitive real-time control over live cameras, recorded clips, slides, infographics, text and capable of streaming live as it happens.

The BoinxTV Interface
There’s almost nothing within BoinxTV that can’t be done with VJ software – with a lot of customisation and editing. The value of BoinxTV is that a lot of functions very useful for live video presentations, have been compiled thoughtfully into an easy to use interface. New features are selected easily and added as layers to the central interface component. Editing and refining for each layer is done in the left side panel, and the right panel shows the master output. Selecting between and triggering layers and events ( eg switching to a new camera, adding an infographic, doing a cross fade to a net based camera etc ) can be done onscreen, with user keyboard shortcuts, a midi controller or via an iPhone app. It’s a fast and efficient system and would greatly simplify the workflow for making video presentations, tutorials, podcasts or framing live event broadcasts.

Features
Aside from the basics (implemented well) such as video switching, camera switching, scaling and adjusting image quality, inserting graphics and text, Boinx also enables the use of high-grade AXIS network cameras, multiple cameras, the easy inclusion of video skype calls from others, integration of RSS feeds for ticker tape scrolls, as well as twitter feeds (allowing comments from viewers), drawing on screen and decent chroma keying (for an easy newsdesk feel or for the use of virtual backdrops). Users can also create their own custom layers using Apple’s Quartz Composer software.

One of it’s best features is the capacity to bundle all of this up and send all the final master out live online – although this isn’t as simple to access as the rest of the features and will hopefully get integrated into a future version. To stream live requires installation of further software ((either GrabberRaster($) or Camtwist (free)), which makes the Boinx signal compatible for the likes of streaming software such as quicktime broadcaster, ustream, stickam and justin.tv.

Bonus points: Using Syphon, Boinx can record real-time HD output from VJ software running on the same laptop (via @fALk_g in Berlin)

Requirements
Intel Multicore CPU based Mac with discrete graphics (MacBook Pro’s starting late 2007), Mac OS X Leopard (10.5.8) or later. QT 7.66 or later. Webcam or professional video camera with Firewire, SDI or HDMI.
And $49 for Home version, $499 for Full version. (See : http://www.boinx.com/boinxtv/home/compare)

Verdict:
The Home version will probably suit most people’s needs, and is a remarkably featured piece of software, which can greatly simplify the production of video presentations, video podcasts, screencasts, and tutorials. It’s also a very easy and convenient way to add a layer of professional depth to any live net broadcasts.

Stop motion ( or stop action ) animation creates the illusion of movement by photographing objects in new positions for every frame. iStopmotion is software dedicated to streamlining that process as much as possible, offering a range of previews, adjustments and relevant effects for monitoring a camera connected to your computer and ensuring accurate controls over the movement of your objects.

Features
While there are for more powerful (and expensive) animation software packages available, the beauty of iStopmotion is in it’s dedicated focus, and the feature set is tailored and trimmed to specifically suit the needs of stop motion animators, avoiding other animation complexities. Below, some of the ways stop motion life becomes easier:

- Image capture adjustments ( flip or rotate image / colour correction and presets / use of overlays and grids for guidance ).
( Note – in terms of image capture, most Canon DSLR cameras are no longer supported in Mac OS X Snow Leopard 10.6.5 and 10.6.6. This is a result of Apple’s dropping of support for those cameras though, not a fault of iStopmotion itself, but hopefully it’s something that will be resolved soon. )
- Onion skinning ( overlays of each frame to allow understanding of how a sequence of movements will look )
- built-in chroma ( or green / blue ) screening
- Custom foregrounds and backgrounds can easily be inserted
- No in-built painting / editing of frames, but it does support easy transferral of frames to Photoshop for that purpose, and then adjusts the frame to suit the new edits.
- Support for using a soundtrack and/or other layers of video as animation guidance.
- Support for the Apple remote control, to capture images from your animation work-table.
- Support for multiple cameras at once
- Integration with Final Cut Pro
- Tilt Shift effect – for applying that miniature real world look.
- Time Lapse capture – create time based effects by capturing frames at specified gaps of time.

And cutely, there’s an option for printing animation sequences as a Flip Book.

Requirements
OS X ( it’s mac only software ), Snow Leopard recommended, but earlier versions still available for use on earlier systems.
Cash: $49 for home version, $99 for Express version and $499 for Pro version ( Major differences are the maximum resolution size, and integration with FCP. Free demo available.

Verdict
No, it’s not After Effects, but for stopmotion enthusiasts, this is a great way to streamline and focus animations.

Scattermusic East Coast Tour Highlights from jeanpoole on Vimeo.

Part of the reason I’ve been quiet on the blog this year, was because of a very busy November and December with video. So it’s good to finally reflect some of that. Back in November I travelled up the Australian East Coast with the Scattermusic Sound System. Which meant 5 guys with 5 laptops in a van for 3 weeks, a dozen gigs, bouncing from Melbourne to Brisbane and back in a space-age Tarago, foam parties, passing through schoolies week in the Gold Coast, realising that our Wagga Wagga gig was at the same time as a world bantam weight boxing match being screened at the same venue, burnouts in Ballarat (as savoured by French Fries who had come along for that gig), Mat Cant twittering away and getting shout outs from Rinse.fm as we travelled, a projector mount that clamped onto anything ( including hotel cabin doorframes for late night movies ), and of course, a never ending supply of great tunes (most overheard sentence in the van? “This track is sick.”)…

Being able to actually document projections in a half-decent way now ( thanks to picking up a Canon 7D last year ), means I’m going to publishing a lot more video online from here in. It’s something that has been a long time coming, and I’m quite happy about finally getting that ball rolling.

Syphon Teaser from vade on Vimeo.

Syphon
Syphon is “an open source Mac OS X technology that allows applications to share frames – full frame rate video or stills – with one another in realtime. Now you can leverage the expressive power of a plethora of tools to mix, mash, edit, sample, texture-map, synthesize, and present your imagery using the best tool for each part of the job. Syphon gives you flexibility to break out of single-app solutions and mix creative applications to suit your needs.”

Out of the box, this means you can send live video signals between these applications: quartz composer, max msp jitter, Freeframe GL and Unity 3D Pro ( a game engine ). Within a short while of release though, this list has been extended to include Modul8 and the MadMapper mapping software, Resolume Avenue, built-in support within the new beta of VDMX, Isadora, CoGe, Open Frameworks, Cinder and Mix Emergency ( software for scratching video with a Serato turntable set-up ).

It all happens on the graphics card, not the CPU, which means HD video can be shuffled between applications at 60 frames per second. This is a great boost for live video flexibility ( lossless live video mixing in and out of 3D game engines? No problem. ), and when it evolves to include being sent over networks, awesome collaborative possibilities await.

Kinect
Another splasher in the visual tech world has been the recent release of the Kinect camera add-on for the XBox. The device features “an RGB camera, depth sensor and multi-array microphone running proprietary software”, and enables 3D motion capture, facial recognition and voice recognition. Being such a hacker’s delight of a device, within a week of release there’s already a growing range of software written that enables it to be used outside the Xbox. Some of these include the ability to draw in 3D (and rotate the image) using gestures, visual FX applications and thanks to Syphon, there’s already a way to include Kinect 3D depth images within Quartz Composer – by first using it within OF and then sending it through Syphon to your visual app of choice.

Notable Kinect shout-outs: real-time light sabers(love the use of the little mirror to frame and juxtapose the original footage here), kinect puppet shows and instant fat-suits.

And there’s a nice extended Kinect round-up of projects over at Creative Applications.

So there you go, the future is already here – *and* it is starting to become more evenly distributed…

What’s a DVD again?

a) “Another Useless Ironic Colourful Object In The Long List of Items Produced By The Falling Western Empire”
b) Plastic taking up room on shelves you wouldn’t need if you didn’t collect plastic
c) A great way to support independent visual artists and musicians
d) A snapfrozen piece of the internet, a medley of fragments and crosswired influences
e) All of the above, ie Faits Divers by Gangpol & Mit, published by Pictoplasma publishing, beautifully packaged and designed by Wiyumi.

“Sonic and Visual in Love”
Faits Divers finds my favourite French audiovisual duo heading off into a more narrative driven direction than previous animated efforts. Sure, the sugarbuzzy pop charm is still there, and they are still farming the possibilities of blending nostalgic sounds and visions with a caricatured cutting edge tech. Where this once presented itself as mutant rhythmic AV probably best suited to a live environment, we are now treated to extended explorations in their cartoon worlds – where deviant plots unfold over time and the music doesn’t try to fit so much in at all times.

“Many of the characters in the clips are easily read as extensions of the creators themselves, battling it out on the ping-pong table, aloof deities on a tiny cloud, lusty beings united in tantric embraces, or sailors stranded on a distant shore, on the verge of embracing cannibalism”

The DVD comes in 4 flavours: Clips/Stories (eg The Hatred Boat), Activities (eg Stand on Waste) and Art with Heart (Interviews with fake artists) and Archives. There is no option to play the soundtrack by itself, which is maybe deliberate, but there is available:
“A special free gift mp3 package delivering 4 new edits of its soundtrack, alternative versions especially reworked to animate your new years celebrations, wedding parties, mystic choirs, ethnic orchestras and goat skin percussions etc”.

“In times where digital media and low-cost travel shrink the globe to the size of a pixel, we are haunted by the computer generated nightmare version of this carnival. The man-eating feast is taken place just millimetres below your computer screen – slaughter on the motherboard.”

“Gangpol & Mit’s message is subliminal: Eat technology before technology eats you!”

Everything in quotation marks has been nabbed from the French horse’s mouth… ie the DVD liner notes*, “The Cannibalist Ethos of Techno Cannibalism,” by Lars Denicke and Peter Thaler, or the G+M website, where many treats await you.

Meathaus is a number of things – a loose collective of New York cartoonists and illustrators, a sporadic comic anthology, and a fantastic blog abundantly filled with wonky and woozy illustrations and comics. Check their about page for their amusing modus operandi.. or their wikipedia page which lists those who’ve been on-team over time, including the likes of now-famous illustrator James Jean and the engaging and disturbing comic storyteller..

If already gobbled, then you’d be excited to know that Dash has followed up his animation series, The Unclothed Man in the 35th Century A.D, with work on an animated feature film, Ruined Cast. It’s great to see something so far from the Disney template getting the feature green-light, and even better that work in progress is available to view: Ruined Cast.

Scott McCloud’s Blog
Aye, the author of the oft-revered ‘Understanding Comics’ ( great for thinking about art, multimedia and the web, not just comics), has a site, blog, and twitter account. Very comic-finger pulsey, for those inclined. I’ve been enjoying his blog over the last few months because it often points to innovative web designs and comics I mightn’t have otherwise discovered, such as… Vincent Giard This Montreal-based cartoonist has a huge palette of vivid illustration style, but I especially enjoy the way he uses animated GIFS within a series of comic panels to create something that lies in between comics and animation – there’s a few hours to be lost clicking through all these pages.

Thisisnthappiness.com
Another collater of unusual images, these kind of sites are swarming all over tumblr now, but this one manages to keep the images eclectic and surprising enough to stay interesting.

A quick guide to using photographs for making time lapse movies (or rubbery timed stop motion animations).

Nutshelly
Sequence 24, 25 or 30 ( for film / PAL / ntsc ) photographs after one another, and you’ve got yourself a one second movie. Stitching these photos together can be as easy as naming the files sequentially, keeping them in a folder, and then opening them with Quicktime Pro on mac or PC. Choose File > Open Image Sequence, then select the first image within the folder, choose the frame rate when the option appears, and then Quicktime will open all of the images as a playable movie. You can also do this within most animation and video editing software, and even from within photoshop, but the quicktime method is most painless, given the often huge number of photos involved.

For those who like shooting RAW (here’s why you should), After Effects unfortunately can’t process RAW files directly, but Creative COW shows you how to import a .jpeg or .tiff sequence into Adobe After Effects with Adobe Camera Raw development settings applied. Regardless of which method you choose, the high resolution of many photographic cameras means using photographs to create a time lapse can deliver a much higher resolution movie than most video cameras are capable of. Fun times ahead.

Timing Your Photographs
An intervalometer is a cheap device ( from $30 on bay + amazon, which effectively mimic more expensive options that can run into the hundreds ), that allows cameras to be programmed to open their shutters at timed intervals (or you can make your own). Experiment with different time, exposure and shutter settings to see the results they give.

Learn from the BBC Nature Dept.
Who better to trust on a time lapse tutorial, than someone from the BBC documentary division? Some take away tips from a lengthy and insightful post on DIY time lapsing by Timothy Allen:

1. Use manual settings on your camera
2. Set your ISO to its lowest if shooting in daylight without ND filters
3. Solid tripod = no camera movement
4. Longer shutter speed = more realistic movement (up to a point)
5. Set your interval according to how fast you want the action to move
6. Check that your memory card has sufficient free space for your images
7. Make sure you have enough battery power to last the duration of shooting.

The whole article is worth reading for more detailed insights into exposure, reducing flicker, equipment tips and how to approach panning time lapses – with a link to a particularly mind boggling behind the scenes video from the BBC’s Life documentary.

Volcanic Time Lapses
Sean Stiegemeier’s time lapse of the recent Icelandic volcanoes, utilises a motorised dolly to provide a graceful and awe inspiring look at the spewing ash clouds ( and nice soundtrack from Iceland native, Jonsi of Sigur Ros).

HDR Time Lapses
And then there’s HDR time-lapse techniques. High dynamic range imaging involves taking three separate photos at separate exposure values then combining the highlights, midtones and shadows of these into one image. HDR time lapse video then requires three sets of photos to be first combined, and then imported as sequence.

Also worth a look? dragonstopmotion.com, a “premier capture software for stop-motion animation, motion design and visual effects,” with quite a range of features, including direct control of Canon + Nikon DSLRs.

Under The Dome
The Melbourne Planetarium (at the Scienceworks Museum in Spotswood) features a ’16m domed ceiling, reclining seats, a stereo surround sound system and has recently been upgraded to incorporate Sky-Skan’s DigitalSky projection system’. In practice, this means craning your neck around everywhere to see what’s happening beyond your peripheral vision. MIFF featured 3 compilations of dome films, and I opted for the experimental collection – which could’ve been called screensaver collection and only a couple of films would’ve suffered by that description.

Domefest / Elumenati
Part of the compilation came from Domefest, an annual screening curated by Artslab, an interdisciplinary arts centre in the New Mexico desert. A big of googling reveals that festival to be connected with another group, Elumenati, virtuoso specialists in the field immersive projection design. Which also happens to be a group that Johnny De Kam ( founder of VDMX and vidvox.net ) has done a lot of work with. Small world dome thingy.

Anyways, best film of the evening? Celestial Mechanics by Scott Hessels (2005), which aimed to visualise the manmade aerial technologies between us and the heavens, starting from police and news helicopters, and working through a range of transmitters and satellites, beautifully evoking their processes as it unfolded. Less good? Cosmic Dance, self-described as ‘astrophysics meets Bollywood’, and a painful 48 minutes of a patronising female host, who when not speaking down to the audience, was being washed in cliched special effects and dancing with the universe. Or something.

DIY DOMING
“DomeXF is a content plug-in for Adobe After Effects, Windows version. For fulldome producers, it is a key tool for transforming flat-screen content to the dome. The DomeXF plug-in for Adobe After Effects is available from Sky-Skan for $395USD”.

DomeXF offers the three standard Full Dome video transformations: standard, panoramic and fisheye.
• Standard transformations give the artist the ability to represent true geometry on the dome allowing the composite layer to appear flat and undistorted.
• Panoramic transformations force the bottom of the composite layer to align with the horizon, even when resized.
• Fisheye transformations give the composite layer depth, akin to the traditional all-sky transformation.

And a vast array of potential filming and projection transformative possibilities await you at Paul Bourke’s site of maths and video surfaces.

Dome Lab 2010 wants you, applications due Friday 3 September 2010, masterclass to be held 31 October – 5 November 2010 :: Perth, Australia.

“… most fulldome content to date has been educational and comprised of computer-generated animation, data visualistion, or a combination of both. Now, however, there is a shifting focus, with producers turning their sights to the entertainment potential of live-action story-telling for large-formats such as fulldome. Dome Lab is a world-leading intensive workshop investigating this potential and the specific challenges involved in creating compelling live-action narrative content for large format and frameless screens.

Filmmakers and artists excited by the chance to leap beyond the frame and into the expansive creative potential of large-format, immersive screen experiences are invited to apply. Participants will work alongside a team of creative and technical luminaries including Academy-Award winner, Ben Shedd, 2010 Peter Rasmussen award-winner, Peter Morse and international fulldome pioneer, Hue Walker Bumgarner-Kirby.”

All below are cheap options, and can be frowned upon by photography purists – you’ll lose some of your camera controls ( eg autofocus), but when used for DSLR video, image quality is still fantastic compared to traditional video cameras in the same price range, and really, you’re swimming in miniature worlds, and potentially capturing them in HD video.

Macro Conversion Lenses
Option one – find out what diameter size your lense is ( it’ll look like this on the lens – Ø72, meaning 72mm ), then buy a cheap lens add on magnifier of the same diameter that will screw on. An Ebay search for ‘macro lens kit’ will deliver a cheap collection of lenses with a variety of magnifications.

Reverser Rings
Again, the diameter of your lens is needed her, and when you flush the reverser ring search through Ebay, a small package will arrive from Hong Kong in a week or so. The reverser ring attaches to the front of the lense, which let’s the lens go onto the camera backwards. (Or DIY Reverser ring )

Extender Tubes
These cheap metal cylinders extend the distance your camera’s innards and the end of the lense, enabling a closer minimal focal distance for shooting from.

Bellows
There’s something perversely analogue and satisfying about these, kind of like attaching a small piano accordion to your digital pixel capture magic box. They allow easy fine tuned adjustments, moving the lens with respect to the focal plane for focusing. ( Crazier, more expensive tilt-shift bellows option, with full Canon EOS controls retained by camera: Novoflex have you covered.)

Or You Could Just Use
A Pringles can. And aye, naturally, there are many DIY iphone macro photography tutorials ( eg Instructables ). Mostly they involve magnifying glasses of some sort in front of the camera lense. Or maybe a video endoscope‘s more your flavour?

Challenges?
Depth of field will be a problem. Even very, very small movements with the camera will take objects in and out of focus. Stability is key then, and DIY stages / environments for objects, even better. Lighting can also be a problem, both in terms of having the camera so close to the object, and with the extra lense lengths being added, letting less light through to the camera. This can be solved with ring lights which fit around a lens, or thoughtful side lighting / reflected light.

Be off swimming with the micro-beasties now, won’t you?

Hassle Canon to sell a 7D at cost price in exchange for review, knowing from using the camera, and seeing online videos, that this is a most desirable camera for shooting video.

Part 2: Zoom In

Focus the review on the video qualities of the Canon 7D, knowing that the Canon 5D MK II has much better photo image quality, and that while other video cameras are on the horizon, which promise similarly large sensors but better video handling controls ( eg the SONY NEX range), the 7D holds a unique position for video capture at this point.

Part 3: Dirt, Meet Fingernails

Run around with the camera a bit, see what it can do ( it sucks light in! ), see how it feels ( sturdy, solid, well built). Think back about shooting video with it, and analyse each component.

The Body
Jumping inside, the camera’s sensor is APS-C sized which means the focal range of all lenses used with it need to be multiplied by 1.6 ( eg a 50mm lens which gives a natural perspective on a full framed camera, will look like an 80mm lens on the Canon 7D – 50×1.6 = 80mm = a lense which gives a slightly zoomed in perspective.) Lenses are separate, and not something being considered here, but the camera itself feels great. Controls are precise and reliable, built to last. That said, this is not a traditional video camera, with ergonomic focus and zoom adjustments within reach. The small size ( relative to a big video camera) also means stabilisation is needed to prevent too much wobble-cam. There is a smorgasbord of companies rushing to supply supporting rigs, but the cost of these also needs to be considered up front if video is your goal.

Software
- Highly customisable interface ( hardware buttons can be re-defined / has 3 custom global settings for easy access to specific settings to suit particular shooting conditions )
- Saves files to a Compact Flash card, in the H264 codec. (Good quality, but needs transcoding into editing software)

Image Quality
Utterly gorgeous. Induces giddy laughter in low-light. It’s not without issues ( google 7D + jello-cam, rolling shutter, moire and aliasing ), but if you’ve come from any other video camera in the same price range, you’ll mostly just be slack-jaw amazed at what the camera is capable of.

Audio Quality
As lame as might be expected for what is essentially a photographic camera slowly morphing into becoming a video camera. A work around? Record using an external recorder such as the Zoom H4N, and use PluralEyes software to auto-sync up your high quality audio files with your lower quality ones, within your video editing software. Once synced, delete the bad audio, and your filmic masterpiece now has rich sound to match.

Part 4: Duel at Dawn

Compare the 7D with the 5D Mk II, the 7D’s only true competitor in the field.

5D: Full frame sensor, greater image quality, more depth of field. Better for wide shots. Use up to 25600 ISO ( ie great for low light). 3.9 FPS for photos. 1080p at 30p only. ( ie 1920 x1080 HD progressive / non-interlaced footage at 30 fps ).

7D: Smaller APS-C sensor ( means less image quality, but also means closer to 35mm movie sensor size and possibility, after adding mods, of using cinema lenses ). Better for telephoto shots. Use up to 12800 ISO. 8FPS for photos. 1080/30p (29.97), 1080/25p, 1080/24p (23.976), 720/60p (59.94) and 720/50p ( 50p + 60p footage can effectively create slow-motion footage at 25p and 30p ).

Aside from the above specs, the 7D also has a dedicated video record button, a better LCD screen for viewing in daylight, and better ergonomics for handling. Plus, this guy recommends it for video.

Part 5: Signing Out

When offering some final words of critical acclaim for this most desirable video camera, don’t forget to crowdsource, and point to the huge range of support material online developing around the 7D and it’s enthusiastic fanbase. People like to see it for themselves.

French Rubber

Mr.Oizo, already somewhat notorious from his audio exploits at Ed Banger records, has earlier branched out into music video and film making. Steak, a feature released only in France in 2007, had a plot based around kidnapping, plastic surgery and the fashion world, and handily, featured cameos from French artists Sebastien Tellier, Kavinsky, and SebastiAn ( who appeared as wheel-chair bound car thieves ). Apparently Mr.Oizo himself, Quentin Dupieux, is the only person who has an English subtitled version, after the French producer lost interest post-release in France.

Rubber on the other hand, is already popping up all over the web video radar, with quirky trailers available at vimeo.com, or fresh from the leathery horse’s mouth at rubberfilm.com ( and as it turns out, writing rubberfilms by mistake, delivers a premium fetish gallery. Not to be confused with Rubber, the 1936 Dutch flick, or Chris Cunningham’s flickerfest, Rubber Johnny ). It’d seem easy enough to think of this as a quirky road movie ( and yet another feature film shot on the Canon 5D), but this rubber tyre serial killer flick might just transcend the genre’s usual offerings. Also on the soundtrack alongside Mr.Oizo, will be Gaspard Augé of Justice ( another Ed Banger ). Make of it all, what you will. See Rubber at the 2010 Melbourne International Film Festival.

And In The Other French Corner..

Being both a master of comic timing and carefully orchestrated cinematography, Jacques Tati‘s films inevitably unfold with visual charm, and an abundance of surprise for the eyes. Playtime, his most famous film, took 9 years to make, was shot on 70mm and involved a set on the outskirts of Paris which resembled a small city in itself. Like his other films, it too took a sword to modern society, lampooning social attitudes and obsessions with gadgetry and convenience, and being near dialogue-less, requires viewing to see just how funny it and Tati are. Interest is high then, for The Illusionist, an animation based on a script by Tati, and directed by Sylvain Chomet ( who also directed the gorgeous Triplets of Belleville animation feature). Tati intended to make the film as a live action film with his daughter, with the plot revolving around ‘a struggling illusionist who visits an isolated community and meets a young lady who is convinced that he is a real magician.’ And being a French production, naturally everything is a little more complicated.

See The Illusionist at the 2010 Melbourne International Film Festival

Car Sharing
Taking a leaf out of Kurt Vonnegut’s book, and looking at civilisation from a distance – we do seem to be a species of oil crazed demons, intent on paving the planet over, and shuffling ourselves around in vehicles that weigh a whole tonne all by themselves. In cities with better urban planning and public transport, it’s obvious to citizens living there that not every single person needs to own a car to survive. Extending this idea another step, car sharing is about renting out cars for short periods of time and thereby reducing the amount of cars needed for a suburb. Some people need a car daily for various reasons, but for others who only need the occasional trip, the car sharing service can save a lot of money ( and other problems such as maintenance etc ). If you drive less than 15,000km a year you will probably find carsharing will save money. There’s three main car sharing groups operating in Sydney and Melbourne, each blowing their own eco-trumpet about the benefts of having access to a newer, fuel efficient car when you need it, and through sharing it with others, effectively reducing the amount of cars needed.

Renting Two Wheels?


Like car rentals, daily bicycle hire has long been an available option for visiting tourists and wandery folk. Arguing that the short trip rental could appeal to the general public, and potentially encourage them to leave cars at home, the Victorian Government has launched a $5 million scheme which will see 600 bicycles available to pick up or drop off at 50 different bike stations across Melbourne. Subscriptions cost $50 a year, $8 a week or $2.50 a day – and the first half an hour of every trip is then free, $2 for the next half an hour and so on. A credit card is needed to participate, and helmets aren’t included, so it’ll be interesting to see whether people find bringing a helmet into the city more convenient than bringing a car. [ Yet to see a single blue bike 'in the wild', though plenty of them seem missing from their racks around the city... ]

Buzzkill
Audio nerds the world over must love soccer, because there’s been a huge outpouring online of ways to filter out the drone. Create Digital Music have done a pretty great round-up of these, tackling everything from EQing with onscreen TV controls ( get rid of 233, 466, 932 and 1864 HZ if you can), free VST plug-ins for mac and pc, acoustic engineers explaining the science of why vuvzelas are annoying ( I actually enjoy the medieval carnival / sacrifice kinda vibe they add ), vuvuzela orchestra ( yes, really ), vuvuzela radio ( uhuh ), and how to re-route audio signals using JACK or Soundflower into another application that has better audio filtering and VST capacities.

Audio Re-Routing
Wormhole2 – allows routing of audio between machines on a network. Now you can make use of all the processing power in your studio. For example; set aside a machine for complex instruments or effects, route audio out to it, then back into your favorite DAW. Or route audio between your PCs and Macs to get the best of both worlds. Or share audio between laptops on stage.

Soundflower is a Mac OS X (10.2 and later) system extension that allows applications to pass audio to other applications. Soundflower is easy to use, it simply presents itself as an audio device, allowing any audio application to send and receive audio with no other support needed. Soundflower is free, open-source, and runs on Mac Intel and PPC computers. IS often used for podcasting to combine tow different audi streams, or to combine skip interview voices etc.

Jack (the Jack Audio Connection Kit ) is a low-latency audio server, written originally for the GNU/Linux operating system, and now with Mac OS X support. It can connect any number of different applications to a single hardware audio device; it also allows applications to send and receive audio to and from each other. Jack is different from other audio server efforts in that it has been designed from the ground up to be suitable for professional audio work. This means that it focuses on two key areas: synchronous execution of all clients, and low latency operation.

Video Re-Routing?
But let’s say you want to send a video signal from one program into another program – how to do that? No such re-routing software currently exists, but there is at least a work around through Vade’s excellent ( and free ) Screen Capture utility. This is a Quartz Composer patch ( and therefore mac only) which allows a portion of the screen to be selected, then sent into another compatible program. This can mean web browsing / web-flash games / computer games etc can all be displayed in one corner of a screen, and then accepted within VJ software such as VDMX and used as a live signal, and filtered, mixed or processed to your heart’s content. ( Be warned : Removing plastic horns visually is likely a bit trickier… )

But Wait, There’s More..
Vade has more in the pipeline, a video re-router that will work fast, and on the graphics card rather than CPU. Tests so far allow easy re-routing between Max MSP / Jitter / Quartz and VDMX. Bookmark his site for announcements to come. And in other news the Auvi Objects have been updated for Max 5, which will please live visualists who remember it.. )

“Auvi was designed with an attitude of sympathy towards beginners. Even now, Auvi can be a lot of fun for those who are less technically advanced — for example, those who don’t want to mess about with shaders and GL. I like to think of Max as a haven for artists whose needs aren’t met by standard software. Auvi was my attempt to increase the fun-factor for these newcomers.” Kurt Ralkse

Soccer Video Remixing
Because you need something to do with all those pipes, right? Recommendo : the 1981 Escape to Victory starring Sylvester Stallone, Michael Caine + Pele in a German prisoner of war camp. Or maybe? Pele’s viagara campaign, where he offers these last smiling words to the camera:
“Talk to your doctor, I would..”
An amusingly careful phrasing, which allows Pele to retain all suggestion of athletic virility, but let anyone else know – Pele says it’s ‘ok’.

Actually Making Stuff From Within Your Browser
How about that! Again, just a convenience in some ways, and not meant to replace your more powerful desktop tools, but sometimes there’s more than enough power right there in your browser.

aviary.com – First shout out must go to Aviary – where from within the browser you can use a variety of their software to do – Photo-editing, adjust vector logos, play with web templates, filters, color palettes, screen captures, edit audio files and more.

looplabs.com – An online music mixing application with an impressive list of features in the sidebar.
online jamming : ninjam.com + jam2jam.com

soundcloud.com – Increasingly popular hosting service, which notably allows comments on specific parts of audio timelines, has convenient dropboxes for easy file sharing, and has many more musician-friendly features. (See intro video for more )

skype.com – Screensharing options for comparing software production notes / techniques / debugging. Voice chat, audio recording.

xtranormal.com – your text + their audio + button to publish = auto generated and published animated movie

pixton.com/uk – Templates for generating online comics.

slideshare.net – Easy development and publishing of slideshows with accompanying audio.

Need Files to Play With?
The popularity of Creative Commons has meant a continued growth of sites legally offering media files for creative re-use :

ccmixter.org – Huge collection of mostly musical sounds, including song parts, and full tracks by the likes of Chuck D and the Beastie Boys, DJ Vadim etc etc.
freesound.org – Giant library of atmospheric, FX and musical sounds.

flickr.com/creativecommons – Flickr’s creative commons collection is ginormous.
http://en.wikipedia.org/wiki/Public_domain_image_resources – Also ginormous.

archive.org – Noble San Fran cats with an abundance, an overload of audio and video work available for re-use. Lots of high quality and unusual vintage material, as well as contemporary netlabels etc.

And What To Do With It All?
Maybe something like this? starwarsuncut.com – where Star Wars is being remade by fans, in 15 second chunks – there are still a few scenes left – sign up and make yours, to be part of the final edit!

Get some print on demand books happening via lulu.com – upload a PDF and no-one pays a cent until a book is ordered online, then it’s printed and delivered to them, money put into your account, and all why you lie in your hammock.

Upload your work to bandcamp.com – and have them offer a variety of free to expensive downloads and even VINYL options!

Make $19,000 in ten hours on Twitter. ( Yes, this may work easier if you are Amanda Palmer )

In other words, you can build your own interactive software or effects using Quartz 2D, Core Image, Core Video, OpenGL, QuickTime, MIDI System Services, RSS (Really Simple Syndication), XML and various hardware inputs ( eg mouse, audio inputs etc ) – without needing to know any code. It is however, also kinda complicated to get a non-programmer head around. The benefits for mac visualists though, are starting to get too large to ignore: continuous developer and community momentum behind it, easy integration into many other applications ( eg VDMX, Resolume for live work, or other apps for production ), a large body of existing examples that can be customised to suit, and the potential to create or invent visual effects, transitions or processes that are exactly suited to your one-off or overall needs.

With that in mind, I’ve decided to try and document my own learning process with it here, and aim to post a weekly-ish blog post exploring what I’m learning, or what I’m struggling with. Hopefully this’ll motivate me to get up to speed quicker, but also provide something useful for someone else. This first post just sets the scene, puts Quartz Composer in some kinda context, and offers up some links to the key online resources for it. With the next post, I’ll try tackle what it feels like to dive into, and how to start making sense of it, what kinds of rules and quirks it has, and how to start making your own quartz patches. Yes, neantherdal baby steps, because they’re mine. Somewhere in the distance, there’s an endgoal though, of being able to execute a range of long desired visual effects and processes that would be handy / interesting in some situations. And so begins the Hobbit like adventure..

What You’ll Need
- A mac running the Leopard ( preferably ) or tiger operating system.
- XCode Tools ( free on the OS installer disc, once installed, Quartz Composer + examples can be found in the /Developer/Applications/ folder).

How does it work?
Quartz Composer creates Quartz Compositions ( motion graphics programs that work by assembling ‘patches’ in a workflow for processing and rendering. There are several types of patches eg Composite Patches / Controller Patches / Environment Patches – Filter Patches etc which can be combined in various ways.

User Interface
Opening up QC, options for Blank Composition, Graphic Animation, Graphic Transition, Image Filter, Music Visualizer, RSS Visualizer and Screensaver offer easy templates to begin from, and give some idea of the program’s scope.

Once open, there are four main windows to consider:
Editor window – a workspace for assembling and connecting patches. Also, on the editor window toolbar clicking the patch parameters button will open up the Patch Parameter Pane – a place for Editing input parameters.
Patch Creator – utility window for browsing and getting information about QC patches and clips. ( A good place to browse and familiarise with available patches )
Patch Inspector – Utility window for editing input parameters and patch related settings.
Viewer Window – Where you get to see the results of all your pixel mangling.

A good beginner exercise is just to open up the example patches that are installed with the program ( found inside Developer/Examples/Quartz Composer ). Exploring some of those will help clarify the relationships between the above four windows, and give an idea of how it operates. I’ll dive in further with the next post, and the resources below will help anyone wanting to keep on trucking.

Alternatives to Itunes For Podcasts
While the iphone/itunes combo can be a delight, it can also be a pain in the ass – Apple extending it’s control too far, and trying to limit how easily media can be moved too and from your device. Stepping outside the itunes publishing monopoly also reminds how much more can be found on the web. And indeed, there are several options for subscribing to podcasts :

Doubletwist.com
This looks interesting, coming from a company with ‘DVD Jon’ onboard ( famous for reverse engineering many pieces of software for the purpose of allowing citizens to do what they wanted with files ):
“We started doubleTwist because we were disappointed by the quality of software applications offered by the major device manufacturers. We feel that just like you don’t use a different browser for every web site you visit (Firefox to read the NY Times, IE to stream Hulu, Chrome to browse YouTube, etc) you shouldn’t have to use iTunes for Apple products, Nokia software for Nokia phones, Sony software for Sony products, etc. The typical household today has many such devices and there is a need for a simple and powerful software that connects them.”
Boasts a much bigger podcast directory than itunes, and features easy sync with any gadget, as well as amazon.com mp3 access.
Songbird ( mac / pc / linux )
Smoother interface, easy gadget syncing, social media integration, artist ticket updates.

Miro ( mac/PC/linux )
Includes audio, video podcast subscribing, bit torrent downloads, HD optimisation, smooth interface.

yamipod.com ( mac / pc / linux )
No podcast services, but worth mentioning as a good freeware app to manage an ipod.

Love to hear about any other recommended podcasts, be it tutorial wise, or clever audio storytelling from the likes of Radiolab… Drop a line if there’s something you love..

- collaborating on projects via tropical hammocks. (“no, no – I think an edit to a darker scene at 1:47.. like this… just a sec.. topping up my coconut juice”)
- remote tutorials (in real-time rather than recording and uploading).
- really direct feedback and refining of work ( compared to email ping pong and uploading / downloading test clips / songs / graphics etc )
- live remixing of processed video from afar

A friend introduced me to this while we were working on an animation project together, and it was so effective at jumping to problem areas on a timeline, and changing things immediately without having to render and upload etc. Move this bit here, put that on the other side of the screen, a bit less of that effect etc.

Working on an animation project with a friend, we began to use it quite a lot to show each other where we were at on the timeline, able to voice chat at the same time, and request to adjust parts, or jump to certain parts of the timeline. Really useful, and

MPEG StreamClip
Elsewhere in the so-damn-useful video software ballpark, is the free MPEG Streamclip from Italy, an awesome but under appreciated bundle of code downloadable from http://www.squared5.com:

“MPEG Streamclip is a powerful free video converter, player, editor for Mac and Windows. It can play many movie files, not only MPEGs; it can convert MPEG files between muxed/demuxed formats for authoring; it can encode movies to many formats, including iPod; it can cut, trim and join movies. MPEG Streamclip can also download videos from YouTube and Google by entering the page URL.

You can use MPEG Streamclip to open and play most movie formats including MPEG files or transport streams; edit them with Cut, Copy, Paste, and Trim; set In/Out points and convert them into muxed or demuxed files, or export them to QuickTime, AVI, DV and MPEG-4 files with more than professional quality, so you can easily import them in a DVD authoring tool, and use them with many other applications or devices.”

It support a huge range of file formats, allows easy cropping of images ( to get rid of bad borders etc ), it does batch processing, it lets you easily export snippets from DVDs, it can split large files onto multiple discs, and the list goes on. A must download for any video-heads.

http://fffff.at/fattag-meet-projector
For whatever reason, the iphone’s video out can’t be used while using apps – without jailbreaking the iphone. In other words, the phone has the capacity, but this is being annoyingly withheld. Once jailbroken, yes, there’s an app for ensuring video out while playing games or using visual tools. And a sign that this dormant feature might become activated? Try the ‘fat tag’ graffiti app – which although doesn’t support video out in it’s official version, has been made available as a custom version that does. Draw, paint, connect video out to projector and there’s a nice little portable touchscreen projection rig right there.

Glimpse a few of their animations and live performances to grasp some more.

http://vimeo.com/6364896
A vibrant array of visual creators constantly pump out material on vimeo.com, so even casual exploration of the site usually brings some rewards. It’s especially nice though, to discover delights in clusters, masses of talented folk orbiting around one of vimeo’s groups or channels. Such as the awesome compilation ‘Everything’, curated by Danny Jelinek, each episode tending to feature 5-6 snappy segments, sharp editing and humour, and sophisticated but whimsically used visual effects.
 
Op Art in Visual Chinatown

davidope.com
http://dvdp.tumblr.com
On the optical art front, albeit with a more contemporary feel, ‘davidope’ creates hypnotic looping animations, which he offers up as a series of tumblr gifs ( hosted at what he calls his ‘visual chinatown’), or java apps / quicktime movs for those inclined. His recipe?

1. I create a simple animated 2d looped pattern in Flash or with Illustrator+Javascript.
2. Then I use them as a displacement/diffuse/alpha map for a static 3d object in 3dsmax.
3. Rendering it with Vray or Illustrate.
4. Finally converting it to GIF with Photoshop.

DJ Yoda 

www.djyoda.co.uk/
youtube.com/user/djyodauk

Belated shout outs to DJ Yoda, who toured Australia in late December. Admittedly I was skeptical after glimpsing a set portion online a long time ago ( too obviously cut and paste in that mid-late 90s way, with little sampling subtlety in the choices or choreography), but for the sonic and visual heads in the audience alike(@ Falls festival) yoda ‘ripped it’, constantly weaving through pop culture grabs with fluid, sophisticated ease. This included a range of recently new worthy items as well as an extended encore of contemporary Australian TV.    

Apart from busily honing his live gigs, DJ Yoda also recently contributed to the DJ Hero game ( Playstation, XBox, Wii ), offering up two mixes for playing : Jackson 5′s “I Want You Back” vs. Gang Starr’s “Just to Get a Rep”, and Little Richard’s “Tutti Frutti” vs. Shlomo’s “Beats”. As an aside – has anyone ever used this? The game made a lot of splashes on release, but I haven’t heard from a single user of it since, or even seen anyone pointing to an interesting video of it (or it’s turntable controller ) in action. Meanwhile, ‘Scratch, The Ultimate DJ‘, being developed by Bedlam games and delayed because of legal troubles, is now back on track – with tracks by Mixmaster Mike, Kid Koala, Gorillaz, Salt N pepa etc. Stay tuned.

The Books ( Mini Review )
John Curtin Hotel ( Carlton, Melb Jan 09)

Thanks to the tasteful way they’d championed the collagey folktronica sound back in the day, what with their sparse guitar, cello, vocals and samples (though never sampling or playing drumkits, only using ‘inanimate objects like children’s toys and filing cabinets, sampled and looped’ ) and their charming albums ‘Thought For Food’ and ‘The Lemon of Pink’, New York duo The Books have gathered quite a following. Expecting they were only in Australia for the Sydney festival, I was pleased to discover they were also doing a Melbourne show, and that it extended their sampling to include video in the live show. Unfortunately the John Curtin’s low stage meant two things – only the front row of the audience could see them performing ( they sat near milk-crates to play with their electronic gear and play their guitar / cello ), and even the onstage projector screen itself was hard to see much of. Eyes closed the music was gorgeous, if a little too perfectly replicating their album sounds. Open eyed, the screen shared some of the responsibility for mirroring the albums so tightly : it seemed they were playing entire tracks of video for each song, which included lots of screen-based audio. Many of their known sample riffs’ then, were sampled from video in the first place, which makes for an absorbing av show, but limits their live improvisation when played as stand alone tracks. Later realised, they released a DVD of 13 music videos, ‘Play All’, in 2007, and you can watch snippets from these at www.thebooksmusic.com. New album on its way, Break, themed around New Age philosophies, and using samples from self-help and hypnotherapy cassettes.

Stingray Sam

Kicking space musical western ass since 2001, the year of his debut feature, American Astronaut, storytelling musician and film director Cory McAbee was in Melbourne recently for the screening of his cinematic follow-up, Stingray Sam. Designed for both mobile devices and the cinema, it’s shot with smaller screens in mind ( a tendency for close-ups rather than long shots, lots of static shots, broken up into six small episodes etc ), the film’s another great vehicle for Cory’s uniquely combined explorations of musical storytelling and cinematic style. Although the songs of his band, The Billy Nayer Show, tend to be comedic, they survive or even thrive on the salt of the earth charm embedded throughout, and it helps that the film(s) can shift into song in such unpredictable ways. Recommendo.

The World As Sonic Map?
Via @ballardian, a link to a nice post about collaborative sound mapping projects – from the BBC, others exploiting Google Maps, and sites that allow to pick a starting point and destination, then present a mix of field recordings between the two places ( sound transit ). The Freesound map gets a deserved shout-out in the comments at the same site, and elsewhere you can listen to the underwater atmosphere of Antarctica in realtime.

All of the above of course presumes we navigate by text / visual cues… what about if we navigated by sound?

The World As Instrument?
The World as instrument: A Theoretical Workshop Taught by Francisco Lopez ::February 16-18 2010

“focused on the historical, sociological and philosophical aspects of different practices that have the “real world” as a source, or an inspiration, for sonic creation. From ancestral manifestations of music derived from nature to the present massive sonic exploration of our world, analyzing the historical attempts at recording sonic reality and creatively transform it, from musical notation to digital technology… the workshop aims at stirring up discussion and at challenging many stereotypical and misleading conceptions about recorded sound in many diverse areas and objects of study, from bioacoustics to experimental music, from phonographs to hard disk recorders, from birds to cosmic radio emissions.”

Chimps are now making movies. It’s true. And their movies are getting screened on the BBC. A bunch of chimps were given access to specially designed chimp-proof cameras as part of a scientific study into how chimpanzees perceive the world and each other, and could also use some touchscreens that allowed them to view remote parts of their enclosure. This was all part of a natural history documentary, and the relevant chimp clips were shown as part of the program Chimpcam on BBC 2.

When Chimps Make Noise
Am eternally indebted to Jim Knox ( I Flips Me Lid ) for casually pointing out that the makers of the Get Smart sitcom also made Lancelot Link, a 24 episode detective series with a cast entirely comprised of chimps. Which isn’t to say they held back on the storyboarding. As well as car driving chase scenes, there were water skiing chases, camel rides in the desert with falcons on shoulder, chimps dressed as undercover surgeons performing surgery – and so on. And then some. Complete with musical interludes to break up the show, with magic trick performing MCs introducing the ‘live band’, of instrument wielding chimps, bashing along in time to some sixties psychedelic sitcom rock. ( More on that here ) The chimp band’s name? ‘The Evolution Revolution’.

Inside The Chimp Mind
Radio Lab at WNYC produce an excellent weeklyish radio show and podcast, where on given themes, they carefully craft together a show using a range of interviews, sounds effects and themselves making provocative jabs at each other. That the end result comes off as so freewheeling and conversational is testament to their editing skills, but anyways – a recent show was about the Animal Mind and they asked whether it was possible for one animal to know what is going on in another animal’s mind, and looked at the problems of anthropomorphising too much (Said one animal scientist : Expecting that every other creature perceives the world as humans do, vastly reduces the complexity and diversity if the world ). Can we really see inside a chimp mind? Or they, ours? What type of communication is really possible? The one hour show is worth listening to for the interesting scientist perspectives, but it’s the tale involving a large, floating whale eyeball that did it for me.

No Chimpee, No Cry

Carson Mell is “an artist/filmmaker living in Hollywood, CA without a wife or an animal”. It said so on the internet : vimeo.com/user520733. Animal owner or not, Carson makes great short films, as featured on the also wonderful Wholphin DVD compilation ( from McSweeneys ), and it’d seem from the sprawling animated carcass of his short about an aging touring rocker, Chonto, Carson and animals, they have a special relationship. Get your Chonto fix at vimeo, or over at http://www.carsonmell.com. (Or aye, full-length atyou-toob )

Chimp Shout-Outs
It’d be appropriate here to mention, Soda Jerk’s The Dawn of Remix which features a wonderful scratch video section using the apes from Kubrick’s 2001 to great effect. Soda Jerk? Those Sydney cine-remixers behind the likes of Picnic at Wolf Creek, Pixel Pirate II. They spend a residency in India recently, so future work may have a Bollywood tinge, and they’re currently working on ‘The Dark Matter Cycle’ of videos, exploring the intersection of death, temporality and cinema. “Go(o)d times”.

And Then There Were None
Did you know there are as little as 21,000 chimpanzees and 25,000 gorillas floating about? As it turns out – around ’1.2 million years ago, only 18,500 early humans were breeding on the planet- evidence that there was a real risk of extinction for our early ancestors, according to a new study‘. We’ve managed to rise to 6.8 billion now. Is is possible there’ll be more chimps than then in another 1.2 million years? Not at our current rates of deforestation. If there is however, what will the future chimps think of the ANIMATED series, Return to Planet of the Apes?

VIDEO
REEL DIRECTOR – $9.99 and a video editing mobile (3GS) now lives in your pocket. Although understandably limited in scope, it does allow to assemble different clips from your library onto a timeline, edit those, and add a variety of transitions.
REEL MOMENTS – by the same company, is all about creating time lapse videos.
SLOMO – let’s you make videos 8 times slower or 2 times faster – with an option to change audio pitch or not.
AClapboard – $7.99
VINTAGE VIDEO MAKER $3 – Adds a retro effect. Not really sold on one-filter apps, but it’s probably a while away before there’s going to be an After Effects killer on a phone. Key frames on trams.

PHOTO / GRAPHICS / ANIMATION
pCAM Film + Digital Calculator $47.99 Calculates Depth of field, focal length matching, running time to length, underwater distances and other long lists of technical details useful for Directors of photography, film, visual effects etc.
phone photos swapped with others randomly?
SKETCHBOOK MOBILE – $5.99 from Autodesk. Multitouch 2500% zoom, paintbrushes 3 layers / import photos. Closest to a mini-photoshop in your pocket I’ve found yet.
PETIT DUMMY – Add any photo, add audio track, select mouth points, create moving animation.
FLICKMATION – Frame by frame animation with layers, onion skinning ( transparency which let’s you see the last frame while drawing the new one ) and a stamp system that can be made from existing photos.
STORYBOARD COMPOSER – $23.99 – An excellent storyboarding app (formerly Hitchcock ), which is possibly the most native feeling app I’ve used. It just seems to harness the touchscreen and gesture controls well, has easy integration of photos, has a great interface, and has a certain immediacy to playing with it, that really encourages exploration.
REAL CAM SP – $1.19 – onscreen menu items to help control iphone camera better… digital zoom, white balance for specific areas in frame etc. That said, there’s a LOT of one-function photography apps out there, with their one cheesy effect that can be added easily to your snap of the day.

INTERACTIVE
TOUCH OSC – $5.99 – Let’s you send and receive Open Sound Control messages over a wi-fi network using the UDP protocol. Which means controlling software on your onstage-laptop, from the dancefloor or in front of the speakers / screen etc. Faders, sliders, an X/Y pad, multi-touch. And a visual editor available from their website.
MRMR – Another OSC app, this one’s free and multi-user by design.
OSCEMOTE – $5.99 multitouch TUIO, accelermoter xyz
ispy Cameras $1.19 – view + control camera from public cams, take screenshots
TONETABLE $9.99 – produces a control tone – for controlling a digital vinyl system – eg serato scratch live / traktor scratch / m-audio’s torq etc. It also allows easy jumping between different pitches through a series of buttons. By the makers of Mix Emergency ( a video mixing app for use with Serato ). And included in this visual app list, because the digital vinyl system can control video as well.
VLC REMOTE $3.99 – Because you wanted a way to browse your hard drive of Al Jazeera recordings from the comfort of your bed.

Shout out to CANABALT, a kind of one-finger Bruce Willis platformer, which has captivated this week. ( My record? 5204m )

When Cinemek’s Jonathan Houser dream of ‘making innovative film tools’ met the iPhone in his pocket, a new mobile storyboarding application was born: Hitchcock. Utilising the iPhone’s touchscreen and built-in camera, Hitchcock adds a layer of fun to location scouting, planning for films and storyboarding sequences. The app has two modes – a panel view that focusses on each shot ( gathered from the photo library ) and allows easy overlays of character stand-ins, camera and character movement and text overlays. The sequential mode allows a finger to slide the panels into a sequence, and control the timing between each shot. There’s something great about the immediacy of being on location, arranging a sequence, and watching it playback to see how well it works as an idea. Hitchcock is a simple app, but executed wonderfully, with a gorgeous interface that encourages play and re-use. When done, press a button and email your completed PDF storyboard. Future developments include : drawing functionality, adding audio, ability to add custom stand-in characters, export to .mov, etc. Cinemek’s Jonathan Houser was happy to answer a few questions about it below.

How do you feel about Hitchcock today?
I’m pretty pleased with how Hitchcock turned out as it is version 1.0. It really accomplishes what I set out to do which was create a lightweight mobile app that allows creative people to jot their ideas down in a visual medium. 

What has the iphone platform been like to develop for?
As a non-coder I was really supprised at how easy it was to design the app under Apples specifications. They provide developers with tons of tools and free API’s. The hardest part for me was to find a person who had the calibre of coding necessary when you reach beyond those free API’s. Jason Thane at General UI did a great job with this. 

What changes would you like in future iphones / the future iphone development environment?
There are many small things that I would like to see. The biggest for me is Apple’s payment process. They are really ambiguous about how they pay you. You may receive reports for a given months sales and the actual fund paid are 20-30% less than what those reports reflect. The worse part is actually contacting them about such problems. It’s pretty messy but I’m sure it’s getting better. 

What’s missing for you to develop Hitchcock on Android?
Right now, proven demand. We have been talking to other developers and the success rate for Android porting is very very low. We have not by any means ruled it out, we are taking it one step at a time. There are many updates to the iphone version of Hitchcock we hope to do before we port to other platforms. 

Hitchock feels like the beginning of an interesting animation sketching app – have you had any thoughts about creating an app that tilted more towards animation?
Yes, we are definitely exploring different specialized uses for Hitchcock. I think the animation community is large enough to warrant a application designed directly for that community.

Other iphone apps that impress?
There are so many – for filmmaking, the guys at Chemical Wedding just released an app called Artemis. It’s a professional director’s finder for the iphone. It contains just about any lens you can think about shooting on. REALLY cool. As for non filmmaking apps, Convert bot has a really cool interface. Its just a conversion app, but the UI team did a great job with the design. Shazam is still such a cool app. There are a bunch of Augmented reality apps coming out which will prove to be pretty useful. 

What aspects of the iphone are least utilised by apps?
I think the biggest aspect of the iphone that is least utilized is multi-touch. It seems like most developers design their apps as ported desktop versions of their app. The buttons are too small and do too little. I think there will be more apps in the future which utilize the whole iphone. 

Do you have a gallery of favourite storyboards submitted by users anywhere?
Not yet. But we are planning on creating a community for that. Keep checking in. 

Popular feature requests?
.mov export is the biggest request. This will be available really shortly. Possibly the beginning of December. Local PDF creation and emailing. Available in the next update as well. Sharing Hitchcock files. This will be available in the Pro version. Many people want to be able to import more PNG’s for stand-ins. We are working on a slick way to exchange PNG’s on a server. This will be a great tool for people who work on specialized projects. Ie car’s, Zombies, Dogs, people with guns etc. 

Other iphone app areas you’d like to explore in the future?
I have a few projects which involved the ipod touch as the software/hardware interface. They are in their infancy still so I cannot go into detail, but they are oriented towards the filmmaking community. 

Hitchcock Demo from cinemek / Hitchcock on Vimeo.

Via Germany : Yes, MAXForLive is near, which should turbocharge audiovisual performance capabilities, bringing together the custom sophistications of MAX/MSP and MAX’s visual Jitter objects, with the musician grade sequencing capacities of Ableton Live, enabling the easy creation of complex and dynamic audio and visual relationships.

Via Hungary : Animata is open source real-time animation software, was built in Kitchen Budapest . It was especially designed for interactive theatre and projections, and
“… the animation – the movement of the puppets, the changes of the background – is generated in real-time, making continuous interaction possible. This ability also permits that physical sensors, cameras or other environmental variables can be attached to the animation of characters, creating a cartoon reacting to its environment. For example, it is quite simple to create a virtual puppet band reacting to live audio input, or set up a scene of drawn characters controlled by the movement of dancers.”

Via Finland: Thanks to Mansteri / Monsteri, a DJ/VJ, Animata can now be controlled with a quartz composer patch and OSC.

Via Hungary : As well as the free open source VJ software CoGe, the http://coge.lovqc.hu/forum also offers two useful quartz composer plug-ins for real-time compositing. CoGePSBrushes is a free and open-source Quartz Composer plugin, which enables photoshop brushes to be used within a quartz composition. And CoGePSDLayers is another Quartz Composer plugin, which allows separated photoshop layers to be played with inside Quartz. Real-time animation.
Via U.S. : You like to code with Open Frameworks? Thanks to Vade, your OF code can now swim happily within Quartz composer.

Theme from above? Quartz Composer. ( Hello summer tutorials )

Hardware?
Via the UK : DVI mixing comes a step closer, ie a mixer is being developed which will input and output VGA and DVI, and allow you to do what nothing else will: dualhead at 1600×600, triplehead at 1920×480, HD at 1920×1080@60Hz. In other words mixing of the good digital signals being given out by a computer, and to a range of screen possibilities. Toby *spark gives more details on his blog, about future availability and potential developments ( add + multiply blends etc ): The project is one where Toby is connecting a manufacturer with potential buyers ( there’s a form to register interest ), but apparently “The Swedes won’t buy a pig in a sack”, so a video is promised to show the existing DVI mixer in action.
