In Shuffle mode, you can move clips freely within a track or onto another track, but their movement is constrained by other clips. That is, if you place several clips in a track, their start and end points automatically snap to each other. You can then “shuffle” their order, but you cannot separate them from each other and you cannot make them overlap as in Slip mode. In Shuffle mode, adding another clip to the beginning of a track moves all subsequent clips to the right by the length of the clip added.
Pro Tools “shuffles” the position of the two clips. The second clip now occurs first, yet the two still cling together.
Locked clips (see Locking Clips), and all clips occurring after the locked clip, are not displaced when other neighboring clips are moved in Shuffle mode. If there is not enough room to place or duplicate a clip in front of a locked clip, the insertion area is disabled.
If you place a clip while in Slip mode and switch to Shuffle mode, Pro Tools preserves the relative timing and position of the slipped clip, and any space between it and other clips.
