How it works

How Sonilo generates background music for a video

  1. 01

    Upload your video

    Choose an MP4 or MOV. Sonilo reads the visuals; your original audio is kept unless you replace it.

  2. 02

    Choose a mood and keep the energy low

    Pick a mood, or type a short prompt such as "warm acoustic background, no lead melody". Enable Keep speech and vocals for a narrated video.

  3. 03

    Generate options

    Sonilo composes several tracks to the video length, using the pacing and scene changes of the edit as context. Compare them against the picture, not on their own.

  4. 04

    Export

    Export the video with the track mixed under your original audio, or download the music as its own file for your editor.

Who this is for

Best for: background music that stays out of the way

Tutorials, vlogs, product walkthroughs, explainers, and corporate videos need music that supports speech rather than competing with it. A stock track is written to be heard on its own, so editors spend time ducking, trimming, and hiding its loop point.

Sonilo composes the track for the video it is given, at the video length. There is no fade-out to fake and no loop seam to hide, and the arrangement can stay sparse where people are talking.

If you want a hook-driven track that leads the video rather than sits under it, start from Add Music to Video instead. Sonilo does not edit your footage.

Common questions

Generate Background Music for Video, answered.

Will the background music be too loud under my voice-over?

Sonilo composes with speech space in mind when Keep speech and vocals is enabled, and you set the mix level before export. Review the balance in the workspace; generated results still need editorial review.

Can I generate background music without uploading a video?

Yes. Text-to-Music takes a prompt and a duration and generates a track without video context. Video-to-Music is the better fit when the music has to follow a specific edit.

How long can the video be?

Video-to-Music accepts MP4 or MOV up to 15 minutes on Premium; Free, Creator, and Pro have shorter per-video limits. The generated track matches the video length. Check current pricing for the limits of your plan.

Can I use the music on a monetized channel or for a client?

Free and Creator output is for personal, non-commercial use. Pro, Premium, Enterprise, and eligible API users have commercial-use rights under the current Sonilo Terms. Check the plan used for the generation and the intended release before publishing.

Is the music original?

Yes. Every track is generated for your video by a model trained on a licensed Shutterstock catalog. Keep the generation record with the project so the source of the music is documented.
