How to add music to video
A holiday clip, a phone slideshow or a short for social media sounds better with a tune under it. The sound is mixed on your device and the picture isn’t encoded again, so even a long video is ready in seconds.
Background music under the video’s own sound
Two sliders set the levels: Video sound and Music. When the clip has sound of its own, the music starts at 40 %, quietly under the voices. Turn it up for a montage, or set Video sound to Off to hear only the song. A soft limiter keeps the mix from crackling when both are loud.
Fades and song length
- The music fades out over the last two seconds by default. Fade in is one tick away in Settings.
- A song shorter than the video starts again, with no click at the joint. Untick Repeat a short song, and after it only the video’s sound is left.
- A song longer than the video stops where the video ends.
Formats and quality
- The picture keeps its quality, because it is copied, not encoded again.
- MP4 stays MP4. WebM gets its sound as Opus.
- The song can be MP3, M4A, WAV, FLAC or OGG, or the sound of another video.
- The new file gets “-music” at the end of its name.
Before you post
Songs you didn’t make may be protected by copyright, and some sites mute such videos. Royalty-free music or your own recordings are the safe choice. For a reel made of several clips, merge them first, then lay one track over the whole thing.

Yes. Drag the frame on the waveform to the chorus. The video then begins right on it.
Yes. Choose that video instead of a song: its sound becomes the music track, and its picture is ignored.
One song per video. Join the two songs into one file with Join audio first, then add that file as the music.
