editing_three point system

To edit content into a sequence using three-point editing, you first set edit points in your source clip and sequence, and then you perform the edit. Three-point editing gets its name from the fact that Final Cut Pro needs no more than three In and Out points (in the Viewer and in the Timeline or Canvas) to determine what part of the source clip to place in a sequence. The result of the edit is dependent on which three points are set in the clip and in the sequence.
