Clip relations are a type of time constraint between two clips so that when you move one clip, the other clip follows proportionately. For example, you may want to create a relation between an audio clip to a shape clip for a lip-synching animation so that when you move one clip along the track, the other clip also moves, maintaining their offset.
For more information, see Linking Clips Together (Relations) [ Nonlinear Animation in the Animation Mixer ].
To apply: Select two clips of any type in the animation mixer and choose Effect 
Create Relation from the mixer's command bar. The first clip you select is the master clip.
To redisplay: Right-click a clip with relations and choose Clip Relation.
