How to add background music to a video clip

Most videos do not need a complicated editing suite just to add background music. You need a simple workflow: upload the clip, choose or generate music, fit it to the video length, set the volume, and export.

Mubert Fuse lets you do that in one browser timeline. You can generate original background music for the clip, upload your own audio, or build a simple mix with voice, subtitles, and sound effects if the video needs more polish.

1. Upload your video clip to Fuse.
2. Choose whether to generate music or upload your own track.
3. Match the music to the video length.
4. Adjust the music volume so it supports the video.
5. Turn on auto-duck if the clip has speech.
6. Export the final video as an MP4.

A common problem with background music is timing. The track is too long, too short, or the best moment of the song does not line up with the video.

Fuse can generate music to match the length of your clip, so you do not have to manually cut a random track into shape. Use presets like Looped Video, Voiceover BG, Advertising, Educational, Funny/Meme, Sport, or Dramatic to get a track that starts from the right mood.

If your video has speech, the background music should not compete with it. Lower the music volume manually, or turn on auto-duck so Fuse lowers the music when someone speaks and brings it back during pauses.

This is useful for:

• talking-head videos;
• product demos;
• tutorials;
• voiceover clips;
• ads;
• educational shorts;
• podcast clips.

You can upload your own music if you already have a track and the rights to use it. If you are not sure whether the track is safe for publishing, check the license first or use a generated replacement.

Fuse-generated music is created for the project and comes with commercial-use licensing on paid plans. That makes it easier to use background music in videos intended for social media, ads, paid posts, or client work.
