Week 7 – Compositing With After Effects

Last Week’s Research Task:

  • What are some standard frame sizes?
  • What are some standard frame rates?
  • What’s the difference between frame based video or field based ( interlaced ) video?
  • What is the difference between Picture aspect ratio and Pixel aspect ratio?
  • What is a codec, and what are their strengths and weaknesses? ( eg H264 / photopjpeg / Apple ProRes / animation )
  • Codec related : Which codecs include alpha channels?
  • Codec related : What is a movie wrapper? What is a container format?
  • What is bitrate? (And what is an optimum bitrate for a video file to be played on the web or in a gallery? )
  • What is the difference between PAL + NTSC?

From the above, devise a list of what the optimum technical settings should be for your video project.
(We will use these settings as the submission criteria.)

After Effects

Rather than let visual effects drive your video – ask – what visual effects does this video need, then try and figure out a way to achieve that effect or look.

If video is a series of frames – how might these frames be treated? (Don’t limit the the use of After Effects to just animating digital images.. experiment with re-contextualised frames or footage to mix digital / analogue effects. What processes might help evoke your ‘perceptions in motion’? ) Some example treatments:

– frames printed out and shredded, repositioned : https://vimeo.com/4211147
– frames printed out and made into origami models : Fast Film by Virgil Widrich (making of) (full clip)

Familiarise yourself with the After Effects interface + workflow: Lynda.com.
For our compositing, colour grading and effects needs – we will mostly focus on these elements of the following Video Co-Pilot tutorials:

  • 01. Introduction
  • 02. Effects
  • 03. Animation
  • 04. Keying & Transparency
  • 08. Titles: 1 & 2
  • 10. Rendering
