When you splice two clips with audio, use the Video/Audio box to specify how the audio is affected.
Select: | To: |
---|---|
Video & Audio | Splice the audio at the same location as the video. If the source clip has no audio tracks, the target clip's audio tracks are overwritten with silence. |
Video | Ignore the audio tracks in the source clip. The audio tracks on the target clip are unaffected. |
