Cut a person out of a video with no green screen and no chroma paint — just upload the clip. The AI separates the subject from whatever's behind them, frame by frame, and gives you a transparent WebM, a green-screen MP4 and an alpha matte. Free, no account, no watermark.
Remove my video background now →VideoBGNinja is built for footage with a person in it — a talking head, a vlog, an interview, a dance clip. It runs Robust Video Matting (RVM), a model that has learned what a human looks like and tracks you through the whole clip with frame-to-frame memory, so edges stay stable while you move. You don't need a green screen, a coloured backdrop or special lighting. Pets and objects sometimes work too, but the model was trained on people, so expect softer, less predictable edges on anything that isn't human — and a clip with no clear person in frame comes back nearly empty.
Green screens key out a colour, so they punish you for wrinkles, uneven lighting, green clothing and spill onto your skin. AI matting keys out the subject instead, so it works in your living room or outdoors with the light you already have.
Deciding between a real screen and AI? The honest trade-offs are in green screen vs AI matting.
Every job hands you three outputs so you're never stuck, whatever app you land in. Your original audio is preserved in the WebM and the green-screen MP4.
| Output | What it is | Reach for it when… |
|---|---|---|
| Transparent WebM | VP9 with a real alpha channel — the background is literally not there | Web pages, OBS overlays, and modern editors (Resolve, Premiere, After Effects) |
| Green-screen MP4 | You, keyed onto clean chroma green (0x00B140) | Any app that can't read alpha — CapCut mobile, TikTok, phone editors |
| Alpha matte MP4 | A black-and-white mask of where you are | Manual compositing as a track matte in After Effects or Resolve |
A transparent WebM stores an alpha channel: every pixel carries a see-through value, so the subject stays fully opaque while the background is simply empty. That's different from a green screen, where the background is a real green colour you still have to remove — here there's nothing to key. Chrome, Edge and Firefox play VP9 alpha natively in a <video> tag, OBS takes it as a media source for overlays, and Resolve, Premiere and After Effects import it directly. For anything that can't read alpha, fall back to the green-screen MP4 below.
Not every app supports transparent video. TikTok, CapCut mobile, most phone editors and older software don't accept an alpha channel — but they all have a chroma-key / green-screen effect. That's why every job also gives you a green-screen MP4: your clip on a clean, uniform chroma green (0x00B140, the exact shade keyers expect), so keying it out is usually a one-click job with no lighting artefacts to fight. Here's where the control lives in the apps people actually use:
Streaming instead of editing? Load the transparent WebM straight into OBS — the full walkthrough is in the OBS transparent overlay guide.
Want the picture-in-picture, floating-presenter look without a green screen? VideoBGNinja isn't a live camera plugin — it works on a file you upload, which is exactly why the result is cleaner than a call app's real-time blur. Record your webcam clip first with whatever you already use (the Camera app, OBS, QuickTime, Photo Booth or your meeting tool's record button), save it as MP4 or WebM, and drop it in. The AI then separates you from your real background and hands back all three outputs. Float the transparent WebM over slides, gameplay or a product shot, or load it as an OBS media source for a live overlay.
Need a subject on crisp white (or any brand colour)? Remove the real background first: once the subject is cut out, the transparent WebM drops onto a white layer in your editor or slide and the empty area shows the white through instantly — no leftover room, desk or wall. Because you keep the transparent version, you can switch white for a brand colour or a gradient later without reshooting, something a real white-cyclorama or lightbox can't offer. One honest caveat: the model is trained on people, so a presenter holding a product cuts out cleanly, but a product filmed on its own — with no person in frame — comes out soft or nearly empty. For pure object shots, a physical sweep still wins.
Swap your real room for any scene — an office, a beach, a brand backdrop. Unlike a video call's built-in virtual background, this isn't a live filter that smears around your hair and flickers when you move; it takes its time on our GPU and tracks you frame by frame, so edges stay clean and stable. Upload your clip, download the transparent WebM (real alpha, so any background shows through), then place any image or video on a layer behind it in your editor and export. You're now in front of whatever scene you like, with no green halo and no wobble.
The tool is tuned for short clips: up to 1 GB and 60 seconds per upload, processed at up to 1280px. Longer material? Trim it into parts first — that keeps processing fast and free for everyone. It runs right in your browser on any device (Windows, macOS, Linux, Chromebook or phone); the work happens on our GPU, not your laptop.
Correct. VideoBGNinja uses Robust Video Matting, which understands what a person looks like and separates them from any background — no green screen, no special lighting.
MP4, MOV, WebM and other common video files, up to 1 GB and 60 seconds per clip.
It's trained on people, so humans work best. Pets and objects sometimes work but with softer edges, and a clip with no person in frame comes out nearly empty — the tool warns you when it can't find one. Try it, it's free.
No — it's not a live plugin. Record your clip first (any webcam or screen-record app), then upload the file. That's also why the result is cleaner than a real-time call filter.
Transparent WebM for the web, OBS and modern editors; green-screen MP4 for TikTok, CapCut mobile and apps without alpha; alpha matte for manual compositing. You get all three from one upload.
Yes. No account, no watermark and no per-clip charge. Ads keep the GPU running.
Your upload is deleted right after processing and the results are wiped within 45 minutes. See privacy.
