Green-screen effects used to require a physical green backdrop, even lighting and careful setup. Now the AI does the keying for you: upload a clip of yourself — filmed in your room, outside, anywhere — and VideoBGNinja returns the same clip with your background replaced by perfect chroma green. Drop it into CapCut, TikTok, Premiere, Resolve or After Effects and key it out like real green-screen footage.
✂ Green-screen my video — freeThe AI (Robust Video Matting) tracks the person through the whole clip with temporal memory, so edges stay stable while you move. You get an MP4 on chroma green (0x00B140 — the exact green every editor's chroma-key filter expects), plus a transparent WebM and an alpha matte as bonuses. Original audio stays in.
Not every app supports transparent video. TikTok, CapCut mobile, Instagram edits and most phone editors don't accept alpha channels — but they all have a chroma-key / green-screen effect. A green-screen MP4 is the universal currency of background replacement.

Up to 1 GB and 60 seconds per clip, processed at up to 1280px. Trim longer videos into parts first.
No — your upload is deleted right after processing and results are wiped within 45 minutes. See the privacy policy.
Chroma green 0x00B140 — the standard shade chroma-key filters are tuned for. Set your keyer to that colour and the background vanishes cleanly.
