Green Screen Live Previewer

Green Screen Live Previewer takes your webcam feed, keys out the green (or blue) backdrop in real time, and drops in a solid color, image, or blur so you can see exactly how clean your chroma key actually is before you hit record on anything. Point it at your camera, pick your key color, and adjust spill suppression and edge softness while watching the live result — it’s built for the five minutes before a stream or recording where you’re checking for wrinkled fabric, uneven lighting, or a stray shadow that’s going to show up as a green fringe around your hair once you’re actually live. Because the video never leaves your browser, it works the same way a local camera-check in any recording software would, just without installing anything.

FAQ

Why does the edge around my hair or hands look rough?

That’s almost always lighting, not the tool — chroma key struggles most where the backdrop and subject share similar brightness or where shadows fall across the green. Evening out the light on the backdrop itself, separate from your key light, usually fixes it faster than adjusting the key settings.

Does this record or export video?

No — it’s a live preview only, meant for checking your setup before you record or stream elsewhere. Nothing you see in it gets saved.

Can I use a photo as the replacement background instead of a solid color?

Yes, you can upload a static image to preview against, which is closer to how the final composited shot will actually look than a flat color fill.

If you’re setting up the shot itself rather than checking the key, Webcam Mirror is the simpler flipped-preview version for framing and positioning before you bring the green screen into it.
