Edits

What are Ripple, Roll, Slip, and Slide Edits

Final Cut Pro provides tools for implementing four types of edits: Ripple, Roll, Slip, and Slide. Each edit will either add time to a particular clip or remove time from it, but each treats the clips before and after the edit in different ways. These tools, available via the Tool Palette and keyboard shortcuts, work with video, audio, and linked video and audio clips.

Roll
The roll edit adds frames to the end of a clip while substracting the same number of frames from the clip beside it, maintaining the length of a sequence. This technique is useful when you are working with two clips that are in synch but need a different edit point between them.

Ripple
The ripple edit adds or subtracts frames from a clip without changing the duration or content of the surrounding clips. (Instead, it increases or decreases the length of the entire sequence.) This is most helpful when you want to extend or trim a clip without changing the surrounding clips.


Slip
The slip edit keeps the duration and position of a clip, but changes its content by shifting the In and Out points within the clip to show a different section of the original media file. The duration of the overall sequence is unchanged, as are the duration and content of the surrounding clips. This technique is helpful if you want to find a better part of a shot, particularly if it's a B-roll or accent shot.


Slide
The slide edit moves a clip left or right in the Timeline, maintaining the clip's duration and content, as well as the duration of the sequence. The surrounding clips will be extended or trimmed in the Timeline to fit the new location of the clip you are sliding. This can be helpful when you need to synch a clip with audio underneath it without disrupting the synchronization of the clips around it.
