Video Background Changer
Replace the scene behind your subject with a described environment.
How it works
Describe the new background and ask the model to keep the subject's shape, position and motion. Check edges and contact shadows in the result.
- 01
Upload the source clip
Drop in the 1–15 second MP4 you already have. It is previewed before anything runs, and its verified duration drives billing.
- 02
Describe the edit
Say what should change — color, background, style — and what must stay the same. A draft preview costs fewer credits for testing.
- 03
Compare and save
Watch the original and the edited clip side by side, then download the result or refine the prompt and run again.
Limits & requirements
- Same source limits as the editor: MP4, 1–15 s, up to 50 MB
- Subject should stay mostly in frame
Prompt template
Replace the background with a minimal sunlit studio. Keep the product's shape, color, position, motion, and camera movement unchanged. Match the new background lighting to the product and keep natural contact shadows.
Good for
Studio-style re-scenes for stable, centered subjects.
Not for
Transparent-background export (keying), subjects leaving the frame.
