Features

  • Replace the sound or mix music under the original.

  • Loops short music to cover the whole video.
  • The picture is kept as is when it's already H.264, so it's fast and lossless.

Frequently asked questions

Does the video get cut to the music length?

No. The result is always as long as the video. Longer music is cut; shorter music loops or stops.

Can I use the sound from another video?

Yes. Add two videos: the first one with a picture is used as the video, the other one's sound as the music.

Can I use copyrighted songs?

Only if you have the rights. Platforms may mute or block videos with copyrighted music.
