Your edit. A new soundtrack.
How can I add music to a video automatically?
Upload your video to Sonilo and generate an original soundtrack around its duration, pacing, and mood. Choose a musical direction, keep speech when needed, and preview the result before exporting the video with music.
It is a video-first music workflow: the soundtrack follows the edit, rather than asking you to recut the video around a stock song.

From upload to export
Add a soundtrack in three steps.
- 01
Start with your video
Choose an MP4 or MOV. Use a finished or near-finished edit so its scene order, timing, and ending can guide the score.
- 02
Set the musical direction
Describe the mood, genre, or instruments. Enable speech preservation for a narrated video, review your settings and credits, then generate in the studio.
- 03
Listen, refine, and export
Preview the soundtrack with the picture. Check dialogue, cuts, and the final frame; adjust the mix or try another version, then export video or audio.
Choose the right workflow
Generate new music, or add an existing song?
Both put music on a video. The difference is where the soundtrack comes from and how much editing it needs.
| Your task | Add an existing track | Generate with Sonilo |
|---|---|---|
| Find the music | Choose a song or search a licensed catalog. | Create a new soundtrack using your video and direction. |
| Fit the edit | Trim, loop, or move the track to fit the cut. | Use video duration and timing as generation context, then review the fit. |
| Keep narration clear | Balance music and voice in your editor. | Keep speech and vocals, then review the mix. Separate audio ducking is available by API. |
| Check usage rights | Check the license for the specific song and release. | Check your Sonilo plan, generation record, and current Terms. |
| Best fit | You already have the right song and its permissions. | You want new music shaped around a video you have already made. |

Common questions
Adding music to video, answered.
How can I add music to a video automatically?
Upload an MP4 or MOV to Sonilo, choose a musical direction, and generate a soundtrack using the video as context. Review the music against the picture, adjust the mix, then export the finished video or audio. Sonilo generates new music rather than choosing a song from a stock library.
Does the music automatically match the length of my video?
Sonilo uses the video duration and visual timing to guide music generation. You can work with the full clip or a selected section in the create workspace. Preview cuts, transitions, speech, and the ending before exporting; generated results still need editorial review.
Can I keep the dialogue or voiceover in my video?
Yes. Enable Keep speech and vocals for the video-to-music workflow, then review the balance of speech and music in the workspace. If you already have separate voice and music files, the audio-ducking API provides a separate workflow for lowering music under speech.
Can I add my own song instead of generating music?
This page starts a new AI soundtrack from your video. If you only need to attach an existing song, a conventional video editor may be the simpler choice. You must have the necessary rights to any music you supply; generating a new soundtrack does not clear the rights to an uploaded song.
Can I try automatic video music for free?
Sonilo offers a Free plan with limited credits. Account, credit, duration, and file-size limits apply, so check current pricing before generating. Free and Creator output is personal and non-commercial; commercial projects need an eligible plan.
Can I use the music for YouTube, ads, and client videos?
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 monetized YouTube videos, ads, or client delivery. Free and Creator output is non-commercial.
What files can I upload and export?
Upload an MP4 or MOV video. The workspace checks the video and the limits of your plan before generation. After reviewing a result, use the export options in the studio to download the video with its soundtrack or the audio for further editing.
Can I automate this workflow in my own app?
Yes. Developers can use the Sonilo Video-to-Music API to submit a video and musical direction. Follow the documented authentication, response format, and task or stream workflow. API access and billing are separate from this website upload form.
