Save tracks to the Library
As with all behaviors in Motion, you can save tracking behaviors to the Library. However, a tracking behavior must reference the tracked source object. Therefore, it may make more sense to save the group that contains the tracking behavior, as well as the source footage, to the Library.
Save a group to the Library
Open the Library and select the category where you want to save the group, such as the Favorites category.
From the Layers list or Timeline, drag the group that contains the tracking behavior and its source (tracked) footage into the stack at the bottom of the Library.
The group is added to the Library category.
Save a behavior to the Library
Open the Library and select the Favorites, Favorites Menu, or Behaviors category.
From the Layers list, Timeline, or Inspector, drag the customized behavior you want to save into the stack at the bottom of the Library.
When you save a customized item to the Library, it is saved in the /Users/username/Library/Application Support/Motion/Library/ folder.
