Editing Video and Audio Simultaneously
When you edit a clip that has both video and audio tracks, you can specify if you want both the video and audio or just the video to be affected by the edit.
The following sections explain how to enable and disable the editing of audio simultaneously with video for both gestural and command-based editing, and the results with various types of edits.
Specifying Tracks for Gestural Editing
Many gestural edits can be applied to both video and audio. The desktop contains the Audio Follows Video box, which you use to specify whether you want the edit to be applied to video or both video and audio.
(a) Audio Follows Video box
To apply the edit only to video:
Only video is affected by the edit.
To apply the edit to video and audio:
The video and both audio tracks are edited simultaneously.
You can also enable or disable Audio Follows Video in the Desktop Preferences menu.
The following table explains which editing functions are affected by the status of the Audio Follows Video button.
| Function | Audio Follows Video Enabled | Audio Follows Video Disabled |
|---|---|---|
| Cut | Cuts are placed in audio tracks at the same location as the video track, and the same portions are removed. | Audio tracks are not cut and the complete audio tracks appear on both parts of the clip. |
| Splice | Splice points are created in audio tracks at the same location as in the video track. If the source clip does not contain audio, the target clip's audio is overwritten with silence. | Audio in the target clip is unaffected; audio on the source clip is ignored. |
| Insert | Splice points are created in audio tracks at the same location as in the video track. If the source clip does not contain audio, the target clip's audio is overwritten with silence. | Audio in the target clip is unaffected; audio on the source clip is ignored. |
| Replace | Splice points are created in audio tracks at the same location as in the video track. If the source clip does not contain audio, the target clip's audio is overwritten with silence. | Audio in the target clip is unaffected; audio on the source clip is ignored. |
Specifying Tracks for Command-Based Editing
Many editing commands can be applied to both video and audio. The applicable menus contain an Video/Audio option box for specifying whether the command is applied to video or both video and audio.

The following table explains how editing functions are affected by the status of the Video/Audio box.

| Splice | Splice points are created in audio tracks at the same location as in the video track. If the source clip does not contain audio, the target clip's audio is overwritten with silence. | Audio in the outgoing clip is kept. |
| Replace | Splice points are created in audio tracks at the same location as in the video track. If the source clip does not contain audio, the target clip's audio is overwritten with silence. | Audio in the target clip is unaffected; audio in the source clip is ignored. |
