Motion tracking is a method of recording the movement of an element (a shape or
reference point in a movie clip) in the Canvas, then applying that recorded movement
data to another element in the Canvas. For example, you can use motion tracking
techniques to pin a post-production graphic to the side of a moving bus, track a blurry
circle to a persons face to preserve an innocent bystander’s anonymity, or replace a
daring stuntmans head with the lazy mug of a leading actor.
