Unstabilize: This behavior does not perform tracking analysis. Instead, the Unstabilize
behavior applies the movement recorded by a Stabilize behavior to a clip or object.
This allows you to match the camera shake in a movie clip to foreground elements
added in post-production. To load the tracking data, choose a track from the Action
pop-up menu, located in the tracking behavior HUD or Inspector.
Note: The Unstabilize behavior can be applied to nearly any object type.
When applicable, you can convert tracking data recorded or referenced by the Match
Move, Stabilize, or Unstabilize behaviors to object keyframes. When converted, the tracking
behavior is removed and the transform keyframes are “baked” into the object. For more
information on converting behaviors, see Converting Tracks to Keyframes.
Shape Track Points Behavior
The Track Points behavior, a member of the Shape behavior subcategory, allows you to
do either of the following:
Track the control points of a shape, paint stroke, or mask to reference features on a
source clip. For example, you can draw a mask around a car in a clip and then track the
control points of the mask to the moving car, cutting the car out of the background.
You can then apply effects to the isolated car, and the surrounding image is not affected.
Apply existing tracking data recorded by the Analyze Motion, Match Move, or Stabilize
tracking behaviors to the control points of a shape or mask.
Note: The Track Points behavior can be applied only to shapes (including paint strokes)
and masks.
Track Behavior
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.
