trackers to the Stabilize behavior.
Unstabilize controls
The Unstabilize behavior is used to apply movement tracked in a Stabilize behavior applied to
another object. This behavior does not perform tracking analysis. The Unstabilize behavior can be
applied to many object types, including groups, cameras, shapes, particle emitters, and so on.
For information on using the Unstabilize behavior, see Unstabilize workflow on page 974.
Parameters in the Inspector
•
Source: Drag a source object for the behavior to this well. The source object can be another
Stabilize behavior or a footage object. To clear a Source well, drag the item away from the well
and release the mouse button.
Track Points controls
The Track Points behavior lets you link the control points of a shape or mask (including paint
strokes) to reference features on a source clip. This behavior also lets you apply tracking data
recorded by the Analyze Motion, Match Move, or Stabilize tracking behaviors to the control
points of a shape or mask.
The Track Points behavior can be found in the Behaviors’ Shape subcategory in the Library,
or by choosing Shape > Track Points from the Add Behavior pop-up menu in the toolbar. For
information on using the Track Points behavior, see
Track Points workflow on page 974.
