How to add audio to a video
- Drop the video. The video stream is copied unchanged, so this is fast and loses no picture quality.
- Add the audio file. MP3, WAV, M4A, OGG or even another video. Choose replace or mix and set the volumes.
- Preview and download. Music shorter than the video can loop or stop; longer music is cut at the end with a fade.

Questions people ask
Can I keep the original sound and add music on top?
Yes. Choose Mix, then set the original and music volumes separately. Choose Replace to drop the original sound entirely.
What if the music is shorter or longer than the video?
Shorter music can loop until the video ends or stop when it ends. Longer music is cut at the end of the video, with an optional fade-out. You can also cut the video to the music length.
Does this re-encode the video?
No. The picture is copied byte for byte; only the audio track is encoded. A five-minute clip is done in seconds.
Which audio formats work?
MP3, WAV, M4A/AAC, OGG, FLAC and Opus, plus the audio track of any video file.
