You can duplicate a clip to create a dependent—also known as an instance—or independent copy of the original source clip. If you create an independent duplicate, you can modify the animation of the original source clip without affecting the duplicate. If you create a dependent duplicate, then any modifications you make to the animation of the original source clip propagates to the dependent clip. The benefit of creating dependent clips is that you can change all the dependent clips on multiple characters with just one edit to their parent clip.
The Duplicate Clip Options window appears. See Duplicate Clip Options.
If you turned on Put Copy in Trax Editor and Visor, the duplicate clip appears in a new track below the original clip’s track and in the Visor.
If you turned on Put Copy in Visor Only, then the duplicate clip is placed only in the Visor.
