Drag the rotation handle in the center of the region to change the angle of the region.

3 After defining the track region, click the Analyze button in the Behaviors Inspector.
Because analysis takes place in the defined track region, the clip is analyzed more quickly.
Unstabilize workflow
Use the Unstabilize tracking behavior to reapply camera shake or movement into a finished clip.
The Unstabilize behavior’s sole function is to apply movement recorded by a Stabilize behavior
to a clip or object, letting you match the camera movement from a background clip to
foreground elements, or to unstabilize a stabilized clip.
Note: A project must include a Stabilize behavior with recorded motion data before you can use
the Unstabilize behavior.
Apply the Unstabilize behavior
1 Select the object to unstabilize, then choose Motion Tracking > Unstabilize from the Add
Behavior pop-up menu in the toolbar.
The behavior is added. If a Stabilize behavior (that has completed an analysis) is present in the
project, the Stabilize data is applied to the Unstabilize behavior.
2 If you don’t want to use the automatically selected Stabilize behavior, do one of the following:
•
In the HUD or Behaviors Inspector, choose a Stabilize behavior from the Action pop-up menu
at the right of the Source well.
•
Drag an analyzed tracking behavior to the Source well in the HUD or Behaviors Inspector.
The motion is applied to the destination object.
Track Points workflow
The Track Points behavior (located in the Shape Behaviors category) is designed for use with
shapes, masks, and paint strokes. Use the Track points behavior in the following ways:
•
To track the control points of a shape or mask to a clip (for example, when rotoscoping)
•
To apply tracking data from another tracking analysis to the control points of a shape or mask
•
To apply the animation of an object to the control points of a shape or mask
Note: To apply the analyzed movement of an object to a shape or mask as a whole (not to the
shape’s control points), use the Match Move behavior.
For a full description of the Track Points parameters, see Track Points controls on page 1003.
