Video & Audio | Insert the source audio tracks along with the video, overwriting the target audio tracks. If the source clip has no audio tracks, the portion of the audio tracks corresponding to the inserted frames on the target clip is overwritten with silence.
Video | Ignore the audio tracks in the source clip. The audio tracks on the target clip are unaffected.
