# Ripple Replace Edits

A ripple replace is an insert edit in which an element that lies between two transitions is “swapped” for the incoming source clip. As the name implies, ripple replace edits ripple, meaning the edit sequence changes duration if the source clip is of a different length than the element it replaces.

To ripple replace gesturally, Ripple must be on. The Ripple Replace hotkey and Ripple Replace option in the Src/Rec Player always ripple regardless of the Ripple mode.

In the following illustration, New Clip replaces Clip B. As New Clip is longer than Clip B, everything after Clip B is moved ahead to accommodate the duration of New Clip.

To ripple replace gesturally:

1. View the edit sequence in Storyboard view.
2. Enable Ripple.
3. Scroll the edit sequence until you see the shot you want to replace.
4. Drag the source clip to the middle of the shot in the edit sequence and release when you see the ripple replace cursor.
