The concepts of planar tracking

VFX trainer Steve Wright has an informative introduction (in QuickTime) to the concepts of planar tracking, the underlying technology behind Mocha tracking tool bundled with After Effects. It's the 1st of a series that will be oriented more to Nuke compositing.

See also Resources for mocha for After Effects and Motion tracking overview and resources in AE Help, as well as AEP posts on Mocha and tracking.

Update: Motionworks collected a few Mocha resources, mostly new ones from Steve Wright in Mocha for After Effects.
