How to Use Green Screen in CapCut (2026): Chroma Key, Step by Step

This post contains affiliate links. If you buy through them, I may earn a commission at no extra cost to you. I only recommend tools I've thoroughly researched.

The fastest way to use green screen in CapCut: add your green-screen clip as an overlay, open the Chroma key tool, and tap the green with the color picker. CapCut drops the green out and shows whatever layer is behind it. Then nudge the strength slider until the edges look clean. It's free on both the phone app and desktop. And if you don't own a physical green screen, skip to the last method: CapCut can cut your background out with no green screen at all.

Key out a real green screen (chroma key)

Use this when you filmed against an actual green (or blue) backdrop and want to drop in a new background.

Step 1: Add your background, then your green clip

Put the background you want (a video or image) on the main timeline. Then add your green-screen footage as an Overlay on top of it, so it sits on a second layer.

Step 2: Open Chroma key

Select the overlay clip. On the phone app, scroll the bottom toolbar to Chroma key. On desktop, select the clip and open the Video panel on the right, then turn on Chroma key (sometimes under Cutout).

Step 3: Sample the green

A color picker or eyedropper appears. Drag it onto the green area of your clip and let go. CapCut removes that color, and your background layer shows through where the green used to be.

Step 4: Clean up the edges

Use the Intensity (or strength) slider to control how much green is removed. Push it up if green is still hanging around the edges, back off if parts of your subject start disappearing. Good lighting on the original green screen makes this step easy. Patchy lighting makes it a fight, no matter the tool.

No green screen? Use auto background removal instead

This is the method most short-form creators actually want, because almost nobody has a green backdrop at home. CapCut can find a person and cut the background out automatically, no green required.

Step 1: Add your clip and a new background

Put your new background on the main timeline, then add your normal footage as an overlay on top.

Step 2: Use Remove BG

Select the overlay, open the Video options, and choose Remove BG, then Auto removal. CapCut detects the person and erases everything behind them, dropping your new background in. No color sampling, no green screen.

Where CapCut's green screen hits its limit

Chroma key is only ever as good as the footage you feed it. Even lighting and a wrinkle-free backdrop give clean edges. Shadows and folds in the green leave a fuzzy outline that no slider fully fixes. The auto background removal is useful, but on busy backgrounds or fast motion it can nibble at hair and fingers, so scrub through and check before you export.

None of this costs anything. Chroma key, overlays, and auto removal are all on the free version.
