How to use Video background remover
The video background remover replaces the background of a short clip with a solid color, frame by frame, using a background-removal model that runs in the browser. It processes up to 20 seconds at 4 frames per second and a maximum width of 640 pixels, then rebuilds an MP4 with the original audio. The default fill is green, #00ff00.

Frequently asked questions
Can I use the video background remover as a green screen?
Yes. The default background color is #00ff00, a common chroma-key green, so the output can be keyed in a video editor. You can pick any other solid color instead.
Why is the output video choppy?
Frames are extracted at 4 frames per second and processed one at a time, so motion looks less smooth than the original. Separate frame processing can also make edges flicker, which the tool notes in its result.
How long can the clip be for background removal?
Set Maximum seconds from 1 to 20, with 10 as the default; the first part of the video up to that length is processed. Clips must produce between 1 and 80 frames at 4 fps.
Where is my input processed?
Source files and text stay in this browser. The first run downloads public models from Hugging Face and local runtime assets from the site. Models may remain in the browser cache. No source upload to Vercel, Supabase or a conversion service is required.
