# Overwriting Clips in an Edit Sequence

When you overwrite existing material in the record clip with new material, the overall length of the record clip does not change. The result of the overwrite edit depends on how you perform the edit. In the following illustration, New Clip is edited gesturally at the transition between Clip A and Clip B. Clip B is overwritten. Clip A and Clip C are unaffected.

You can also edit a source clip into the record clip at any frame. The source will overwrite all existing material for its duration. In the following illustration, New Clip is edited into the record clip at a frame in Clip A. Frames after the insertion point are overwritten by New Clip. All of Clip B and some of Clip C are overwritten.

When you overwrite a section of the timeline with a source clip that contains gaps, you can fill gaps in the source clip with media already on the timeline or preserve the gaps in the source clip.

To overwrite a clip in the Record Area gesturally:

1. Disable Ripple.
2. View the edit sequence in Storyboard view.
   NoteIn Storyboard view, use the edit cursors to guide where your clip will go.
3. Scroll the edit sequence until you see the transition where you want to make the overwrite.
4. Select a source clip and drag it over the edit sequence. As you drag, the cursor changes shape depending on where it is in relation to the underlying clip.

   (a) Source clip (1 frame)(b) Clip beneath cursor (2 frames)(c) Overwrite cursors (green)(d) Duration of sequence before overwrite (00:00:01:03)

5. Drop the source clip where you want to make the overwrite.

   The edit sequence does not change duration to accommodate the new clip.

   (a) Source clip(b) Duration of sequence after overwrite(c) One frame of clip is overwritten by source clip (00:00:01:03)

To overwrite a clip in the Record Area using the hotkey or Src/Rec Player options:

1. Select a source clip.
   NoteTo overwrite with material that starts at a specific frame, move the source timeline positioner to the frame that you want to use as the beginning of the overwrite.
2. Scroll through the edit sequence until you reach the frame where you want to make the overwrite and then do one of the following:
   - Press H or click Overwrite in the Src/Rec Player.
     NoteIf you have a multi-layer source clip with a gap on one of its layers and you want to fill the gap with the media on the corresponding layer, you can also press H or click Overwrite.
   - If you have a multi-layer source clip with a gap on one of its layers and you want to preserve the gap in the source clip, press Shift+H or select Overwrite (Keep Source Gaps) from the Overwrite pulldown list in the Src/Rec Player.
     NoteYou will most likely fill gaps rather than preserve them.
   - To delete the source clip from the Source Area once the copy is edited into the timeline, select Overwrite (Delete Source) from the Insert dropdown list in the Src/Rec Player.
