You can animate shapes using Mocha from Boris FX.
This is the second video in a series about the surface and shape relationship.
Watch Part 1.
In this quick video, Mocha Product Specialist, Mary Poplin, explains the difference between the shape and the surface tool. Mocha's shape based planar tracking can help you solve difficult tracking challenges:
Multiple shapes can be added to one track layer
Shapes can be moved or animated for offset tracking
Shape layers can be stacked to avoid foreground occulsions
Mocha is the ideal tracking and masking plug-in for Adobe, Avid, Nuke and many more hosts.
