How it works

What happens to your file.

The selected audio file is added to the video timeline and encoded into a compatible output. The tool matches the audio and video streams so common players can play the result.

Where it stops: If the audio is longer than the video, it may be trimmed; if it is shorter, the remaining video may be silent depending on settings. Mix levels should be checked before posting.

Questions

Common questions.

Can I replace the original audio?

Yes. Add the new track after muting or replacing the old one.

What audio formats work?

Common audio files such as MP3, WAV, M4A, and OGG are supported through the audio engine.

Will the audio loop automatically?

No. Use an audio editor first if you need a looped track.
