To add a group to a project from the Library
1 Open the Library and select the category that contains the group.
2 Do one of the following:
• To nest the group in an existing group, drag it to the existing group in the Layers tab.
• To create a new group, drag it to an empty area in the lower portion of the Layers tab.
The group is added to the project.
To apply a behavior to a clip from the Library
1 Open the Library and select the Favorites, Favorites Menu, or Behaviors category.
2 Drag the behavior to the clip in the Layers tab, Timeline, or Canvas.
To reference another tracking behavior in a project
1 Add an Analyze Motion, Match Move, Stabilize, or Unstabilize behavior.
2 In the tracking behavior’s HUD or Inspector, choose a track from the tracking behaviors
pop-up menu.
The track is applied to the tracking behavior.
Note: In a Stabilize behavior, only tracks from other Stabilize behaviors can be chosen
from the tracking behaviors pop-up menu.
Tracking Behavior Parameters
The following section provides a detailed description of the parameters available in the
different tracking behaviors.
Note: Cloned objects cannot be tracked.
Analyze Motion Controls
The Analyze Motion behavior is designed for use with footage (a movie or image
sequence). This behavior can be thought of as a “traditional” correlation tracker—you
position an onscreen tracker on a reference pattern on a clip. The movement of the clip
at the specified reference point is analyzed, and the analyzed data is saved in the behavior.
The recorded data can then be applied to other objects in the project.
The Analyze Motion behavior does not transform the input image. It is used only to
generate tracks that can be referenced by the Match Move and Stabilize behaviors.
For information on using the Analyze Motion behavior, see General Motion Tracking
Workflow .
Note: Analyze Motion cannot reference other tracking behaviors.
