The Track behavior, a member of the Parameter behavior subcategory, allows you to
match the position parameters of shapes, clips, or filters (such as the Center parameter
of a Circle Blur filter) to a reference feature of a clip.
The tracking data is obtained in one of two ways:
• After you add the Track behavior to a position parameter, another clip is analyzed in
the Track behavior, and the recorded data is applied to that position parameter.
• Tracking data from another tracking behavior is referenced by the Track behavior. The
recorded data from the referenced behavior is applied to the position parameter.
Note: Although it’s a Parameter behavior, the Track behavior is only designed for use
with position parameters.
