How it works

Upload a clip

MP4, MOV, WebM and more — up to 1 GB and 60 seconds. Filmed anywhere: your room, outside, the office. No green screen needed.

AI separates every frame

Robust Video Matting runs on our own GPU and tracks the subject through the whole clip — hair, motion and all — usually in under a minute.

Download three versions

A transparent WebM, a green-screen MP4 for any editor, and an alpha matte for pro compositing. Original audio stays in.

What people use it for

Talking-head videos

Put yourself over slides, gameplay or product shots — the webcam-cutout look without buying a green screen.

TikTok / Reels / Shorts

Swap your messy room for any background. Export the green-screen MP4 and use your app's chroma-key effect.

Editing & VFX

The alpha matte drops into After Effects, Resolve or Premiere as a track matte — clean edges, no rotoscoping.

Questions, answered

Do I really not need a green screen?

Correct. The AI model (Robust Video Matting) understands what a person looks like and separates them from any background, frame by frame, with temporal tracking so edges stay stable while you move.

What do I get back?

Three files: a WebM with real transparency (VP9 alpha — works in browsers, OBS and modern editors), a green-screen MP4 (universal — key it out anywhere) and an alpha matte MP4 (black & white mask for compositing). Your original audio is kept.

What are the limits?

Max 1 GB and 60 seconds per clip, processed at up to 1280px. Longer material? Trim it into parts first — processing stays fast and free for everyone that way.

What happens to my video?

Your upload is deleted the moment processing finishes, and the results are wiped within 45 minutes. Nothing is stored, watched or used for training. See the privacy policy.

Does it work on animals or objects?

It's trained on people, so humans work best. Pets and objects sometimes work, but expect softer edges — try it, it's free.

Why is it free?

The site is supported by ads. The AI runs on our own hardware, so we don't pay a cloud bill per video — and you don't pay anything at all.
