Video Greenscreen Remover
Remove or replace a green screen background. Upload a video, set the key color and tolerance, preview the result, and record and download the new video — completely free, all inside your browser.
First select a video, then press "Start Preview". The recording downloads in WebM format.
How to use
- Select the video with the green screen.
- Adjust the key color (usually green) and the tolerance slider until the background is cleanly removed.
- Use "Start Preview" to see the live result, then save the new video with "Record & Download".
Tips
- An evenly lit, plain single-color background gives the cleanest key.
- Raise the tolerance slowly: too high starts eating into the subject's edges.
- Watch the preview closely around hair and edges before recording the final video.
Frequently Asked Questions (FAQ)
How do I remove the green screen?
Select the video, adjust the key color (usually green) and the tolerance slider until the background is cleanly removed, preview the result, then record and download the new video.
Can I replace the background instead of just removing it?
Yes. You can leave the background transparent (checker), fill it with a solid color, or place your own image behind the subject.
What kind of background removes most cleanly?
An evenly lit, plain single-color background gives the cleanest key. Raise the tolerance slider slowly, because too high a value starts eating into the subject's edges.
What format does the finished video download as?
The recording downloads in WebM format.
Is my video uploaded anywhere?
No. All processing runs in your browser, and the video never leaves your device.
