Performing an Overwrite Edit in an Advanced Sequence
If you are editing an advanced sequence, you can use the Overwrite feature to replace a portion of the sequence with a clip that is loaded in Asset mode. There are two ways to perform an overwrite edit:
• Click the Overwrite button or press the B key. This method provides you with more options:
- You can use the position indicator as an In point for the overwrite.
- You can perform the overwrite edit from either Asset mode or Output mode.
The following illustration shows the Overwrite button circled. The NAT track is enabled, so that audio in the source clip will overwrite audio in the NAT track.
• Drag a clip from the Media viewer and drop it on the Sequence Timeline. This method is a quick way to build a sequence but has fewer options.
- You can overwrite only from the beginning of a video segment.
- You can drag only when the Media pane is in Asset mode.
The following illustration shows how a video-only overwrite edit is displayed when you drag a clip to the timeline. A thin guideline is displayed through the video track. If you release the mouse button above the guideline, you perform an overwrite edit, as indicated by the red arrow and red overlay.
The following illustration shows how a video and NAT overwrite edit is displayed when you drag a clip to the timeline. The NAT track indicator is enabled.
The examples in this topic use a horizontal timeline. If you are editing a sequence in a vertical timeline, the guideline is also vertical, and the edits are determined by dragging to the left or to the right of the guideline.
If you have both NAT and SOT segments associated with the video, you can enable both tracks to overwrite the video segment and both audio segments. You can enable the VO track, but only VO audio will be overwritten.
You cannot overwrite NAT-only or SOT-only segments.
If you release the mouse button below the guideline, you perform an insert edit, as indicated by the yellow arrow and yellow overlay.
Note the following:
• You can perform an overwrite edit only in an advanced sequence.
• If you use the drag and drop method, and you drop your clip in the Sequence Timeline before the guideline appears (approximately 0.5 second), you perform an insert edit instead of an overwrite edit.
To perform an overwrite edit using the Overwrite button or B key:
1. Load a clip in the Media pane and mark In and Out points.
The amount of material that you overwrite is determined by the In-to-Out duration marked on the clip.
When you use this method, the Media pane can be in either Asset mode or Output mode
2. In the Sequence Timeline, move the position indicator to the location where you want to start the overwrite.
3. (Optional) Click a track selector to enable the audio track or tracks on which you want to overwrite the audio. If you do not enable an audio track, only video is overwritten.
The Video track is always enabled. You can overwrite video only, but you cannot overwrite audio only.
4. Click the Overwrite button or press the B key.
The selected material overwrites the material in the timeline and the position indicator moves to the first frame of the next segment.
To perform an overwrite edit using drag and drop:
1. Load a clip in the Media pane and mark In and Out points.
The amount of material that you overwrite is determined by the In-to-Out duration of the asset.
When you use this method, the Media pane must be in Asset mode.
2. (Optional) Click a track selector to enable the audio track or tracks on which you want to overwrite the audio. If you do not enable an audio track, only video is overwritten.
The Video track is always enabled. You can overwrite video only, but you cannot overwrite audio only.
3. Drag the clip from the Media viewer to a location in the video track of the Sequence Timeline. Make sure the mouse pointer is above the guideline in the middle of the track.
The timeline shows where the overwrite will take place.
Do not release the mouse button before the guideline appears (approximately 0.5 second) or you perform an insert edit instead of an overwrite edit.
4. Release the mouse button.
The selected material overwrites the material in the timeline and the position indicator moves to the first frame of the next segment.
- If the selected material is shorter than the segment that you are overwriting, and you are overwriting only video, the audio of the overwritten segment is preserved and creates an L-cut. The following illustrations show an example of the edit in progress and the result.
- If the selected material is the same length or longer than the segment that you are overwriting, and you are overwriting only video, the audio of the overwritten segment remains in the sequence. The audio is not associated with any video in the timeline. For more information, see
