Video Composer

BachGround Video Composer uses video analysis and your optional brief to create original background music for video. Review the soundtrack with your footage, then refine it in the timeline.

What Video Composer does

Built for filmmakers, editors, and storytellers who need music that reacts to picture instead of merely sitting on top of it.

Reads the edit

Video analysis provides context about scenes, transitions, and pacing to guide the score.

Follows emotion

The mood of your footage and your creative brief help guide the musical direction.

Writes for your footage

The result is a bespoke score shaped around your visuals, not a generic stock track.

Edit music timing, volume, and fades in the timeline. Adjust music and source-audio levels independently, change automatic ducking intensity, and generate music for selected regions. Export WAV or MP3 audio, or your video with its soundtrack.

How it Works

01
Upload Your Vision
Upload an MP4 or MOV video. Video analysis provides context about its scenes, pacing, and mood to guide music generation.
02
Define the Vibe (Optional)
Use the Creative Direction Brief. Want a "cello-heavy noir atmosphere" during the rainy alleyway scene? Just say so. You can refer to specific scenes by description or timestamp or leave it blank and let the AI interpret the mood for you.
03
Generate & Edit
Generate a soundtrack informed by your video, preview it with the footage, and adjust timing, volume, and fades in the timeline. Review the result before exporting; synchronization may need refinement.

An independent project

We are a small, independent startup of researchers and musicians. Video Composer is our maiden product, the result of countless hours of fine-tuning and development.

We are currently in an active experimental phase, working around the clock to upgrade the engine, improve synchronization accuracy, and expand our musical vocabulary.

Starter usage and ongoing plans

New accounts receive limited, one-time starter usage to try Video Composer. This is not a recurring free subscription tier. For ongoing generation, choose a monthly or annual subscription or purchase persistent credits.

Every purchase helps cover the computing power required to render your score and supports the continued development of BachGround. By choosing us, you are supporting an independent project built by creators, for creators.
