analyzed more quickly.
Unstabilize Workflow
This section provides a basic overview of using 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 another
tracking behavior, such as Stabilize, to a clip or object. This allows you to match the
camera movement from a background clip to foreground elements, or unstabilize a
stabilized clip.
Note: A project must include a tracking behavior with recorded motion data in order to
use the Unstabilize behavior.
To use the Unstabilize behavior
1 Select the object you want to unstabilize, click the Add Behavior icon in the Toolbar, then
choose Motion Tracking > Unstabilize from the pop-up menu.
The behavior is added. If a Stabilize behavior (that has completed an analysis) is present
in the project, the Stabilize data is automatically applied to the Unstabilize.
2 If you don’t want to use the Stabilize behavior that is auto-selected, do one of the
following:
• In the HUD or Behaviors tab of the Inspector, choose a tracking behavior from the
pop-up menu to the right of the Source well.
