Ripple Overwrite
Ripple Overwrite is a four-point edit that’s useful when you can identify a segment of the
Timeline you want to overwrite, but the incoming clip is of a different duration and you want
DaVinci Resolve to automatically ripple the Timeline to accommodate the difference.
You can use the Ripple Overwrite command one of two different ways:
 You can overwrite an entire clip in the Timeline with another clip of different length.
 You can overwrite a section of the Timeline marked with In and Out points with a
another clip of different length.
In both cases, all clips to the right of the clip or timeline section being overwritten are rippled to
the right or left to make room or fill the gap. Because of this, the ripple overwrite edit will most
likely change the overall duration of your edited sequence of clips.
Using Ripple Overwrite on an Entire Clip in the Timeline
Using ripple overwrite as an automatic four-point edit, you can overwrite whichever clip in the
Timeline intersects the playhead on the tracks defined by the destination controls, in its
entirety, with the incoming clip. For this to work, there must be no In or Out points set in
the Timeline.
After performing a ripple overwrite in this way, the original timeline clip is eliminated and the
incoming clip takes its place, and all clips to the right of the clip being replaced are either (a)
rippled to the right if the incoming clip is longer than the original timeline clip, or (b) rippled to
the left if the incoming clip is shorter than the original timeline clip. All of this is done in a
single step.
This is useful in situations where you want to quickly switch one clip in the Timeline with another
of unequal duration and have the Timeline automatically make room to allow this all in one step.
To use ripple overwrite to replace an entire clip in the Timeline with another source clip:
1 Move the playhead in the Timeline to intersect the clip that you want to replace; the
playhead’s exact position is not important.
2 Click the appropriate audio and video destination controls of the track containing the
clip you want to replace, and press Option-X to eliminate any In and Out points there
might be in the Timeline.
3 Open a clip into the Source Viewer, and set In and/or Out points as necessary to define
how much of the clip you want to edit into the Timeline.
4 To execute the edit, choose Edit > Ripple Overwrite, drag the clip to the Ripple
Overwrite overlay of the Timeline Viewer, or press Shift-F10.
Before and after of using ripple overwrite with no Timeline In or Out points; Clip K at the
position of the playhead is replaced in its entirety by the short segment of Clip U from the
Source Viewer; all clips with In points to the right are rippled to the left to fill the gap
