CapCut how-to
How to use green screen (chroma key) in CapCut
Short answer
Put your new background on the main track and the green-screen clip on an overlay track above it. Select the overlay, open Remove BG > Chroma key, use the colour picker on the green, then raise Intensity and adjust Shadow (and edge controls on desktop) until the green disappears cleanly.

If it doesn't work
| What you see | Fix |
|---|---|
| Green patches remain | Re-pick the colour on the darkest green area and raise Intensity in small steps. |
| Holes in the subject | Intensity too high, or the subject wears green. Lower Intensity. |
| Chroma key option greyed out | Select the upper clip; the lower track doesn't offer it. |
| Uneven result | CapCut's help: the background must be clean and evenly lit; replace low-quality footage. |
Questions people ask
Why is my CapCut chroma key not working?
Usually the wrong clip is selected or the green isn't evenly lit. Select the overlay, re-pick the colour and adjust Intensity and Shadow.
Do I need a real green screen?
No. Remove BG > Auto removal works without one, but chroma key on an even green gives cleaner edges.
Can I use a blue screen?
Yes; pick the blue with the colour picker.
