Technical Details

Chroma keying works by identifying pixels that fall within a specific color range (typically green or blue) and making them transparent. The challenge is handling the transition zone at the edges of the subject, where foreground and background colors blend due to motion blur, hair detail, or imperfect lighting. The tool provides tolerance controls to define how wide the target color range is, and edge feathering to soften the boundary between the kept and removed areas. Spill suppression reduces the green or blue color cast that often reflects onto the subject from the backdrop. These controls work together to produce a clean composite.

Frequently Asked Questions

My background isn't being fully removed. What should I adjust?

Increase the tolerance slider to capture more shades of the key color. If your green screen has uneven lighting, you may need a higher tolerance. Be careful not to go too high, or you'll start removing parts of your subject.

Can I use colors other than green or blue?

Yes. Use the eyedropper tool to pick any background color. Green and blue are standard because they're least likely to match skin tones, but any solid color backdrop will work.

Why are the edges around my subject rough?

Increase the edge feathering slider to soften the transition. Also check that your original footage has good lighting — harsh shadows and wrinkles in the backdrop make clean edges harder to achieve.

Can I export with a transparent background?

Yes. Choose the transparent background option and export as WebM, which supports alpha channels. Note that MP4 does not support transparency.
