How to remove a green screen in CapCut

First: do you actually need chroma key?

Chroma key exists for files that have a coloured background baked in. If your overlay came with a transparent version, use that instead — CapCut reads transparent .mov files directly, so there's nothing to remove. Every BRANDED.GG order includes a Transparent Background folder for exactly this reason; the green screen version is only a backup for the odd app that can't read transparency. If you do need to key out green, read on.

On CapCut desktop

1. Import the green screen file and drag it onto a track ABOVE your main video.
2. Click the overlay clip on the timeline to select it.
3. In the panel on the right, open the Video settings and find 'Remove BG'.
4. Tick 'Chroma key', then click the colour picker and click on the green in the preview.
5. Raise the Intensity slider until the green disappears. Stop as soon as it's gone — going further starts eating into the graphic itself.
6. Use the Shadow (edge) slider to soften any hard green outline left around the graphic.

On CapCut mobile

1. Save the green screen file to your phone first.
2. In your project, tap Overlay → Add overlay and pick the file.
3. Tap the overlay clip to select it, then find 'Remove BG' in the toolbar (some older versions call this 'Cutout').
4. Choose 'Chroma key' and drag the colour picker circle over a solid green area.
5. Adjust Intensity until the green is gone, then Shadow to clean up the edges.

CapCut moves its menus around between updates. If you can't see 'Remove BG', select the clip and scroll the bottom toolbar — Chroma key always lives with the background-removal tools.

Getting a clean key

1. Pick the colour from the middle of a flat green area, not near the edge of the graphic where colours blend.
2. Zoom in on the preview and check soft parts — glows, shadows and motion blur are where green fringing shows up first.
3. Play the whole clip, not just one frame. A key that looks fine on a still can flicker as the animation moves.
4. Don't use the automatic 'Remove background' (the AI cutout meant for people) on graphics — it guesses at edges and can flicker frame to frame.

Why green screen is the backup, not the first choice

Chroma keying works by deleting every pixel close to the chosen colour. That causes three problems with animated graphics. First, a thin green fringe often survives around edges, especially on text. Second, anything semi-transparent — glows, soft shadows, glass effects — gets either cut away or left with a green tint, because a green screen file can't store 'half see-through'. Third, any green in the design itself gets removed too: a Kick-green button, a green brand colour or a green emoji can vanish along with the background. A transparent file stores real transparency for every pixel, so none of that happens.

Common problems and fixes

1. There's still a green outline: raise Shadow slightly, or lower Intensity and re-pick the colour closer to the edge.
2. Parts of the graphic disappeared: Intensity is too high, or the design contains green. Lower Intensity — and switch to the transparent file if it has green in it.
3. It looks blurry: the overlay may have been scaled up a lot. Keep overlays at or below their original size where you can.
4. The exported video has a green tint around glows: that's the limit of keying. The transparent version fixes it.
