Replace Audio in Video swaps a video’s soundtrack for another audio file: a song, a voice-over, a dubbed track or a cleaned-up recording. It opens with Replace it with the music selected, so the original sound is dropped. The picture is copied without re-encoding: the quality is unchanged and even a long video is done in seconds.
Common reasons to replace the sound
| Problem | New audio |
|---|---|
| Wind, traffic or crowd noise | Music, or the sound cleaned with Noise Reduction |
| A take with a mistake in the voice | A re-recorded voice-over from the Voice Recorder |
| Music you cannot use on a platform | A track you have the rights to |
| A video in the wrong language | A dubbed audio track |
Tips
- To line the new sound up, type a start time such as 0:01.5. Play the result and adjust if it is early or late.
- Untick Repeat the music to the end for voices and dubbed tracks; keep it for short music loops.
- To only remove the sound, without adding any, use Mute Video.
