The clip order decides whether CapCut's green screen works. Put the replacement background on the lower track and the green-screen footage above it. Select the upper clip, open Remove BG, enable Chroma Key, and sample a flat part of the screen. Raise Intensity or Strength only until the background disappears, then refine the edge.
CapCut's current help pages list Edit → Remove BG → Chroma Key on Mobile and Video → Remove BG → Chroma key on Desktop. The Web route begins at Smart tools → Remove background. Labels still differ between builds, so the guide separates platform paths and explains what each control does.
Choose Chroma Key, Auto removal, or Custom removal
Pick Chroma Key when the source has an even green, blue, or other solid-color backdrop. The tool removes the color you select, so you control the sample and the edge directly. CapCut's green-screen guide recommends this method for solid green or blue screens.
Auto removal fits a person or clear subject recorded in an ordinary room. Reach for Custom removal when the available brush and eraser tools suit a difficult outline better. Those two routes solve a different source-footage problem. Our CapCut background-removal guide covers footage without a solid screen.
CapCut's online Chroma Key page currently advertises the core tool as free with no credit card required. A plan badge can still appear on an adjacent AI or cleanup control. Treat the badge and export message in your own account as the current plan boundary.
Put the two clips in the right order
- Import the replacement background and the green-screen footage.
- Place the background on the lower video track.
- Place the green-screen footage directly above it. On Mobile, add this clip as an overlay.
- Extend the lower background under the full duration of the upper clip.
- Select the upper clip before opening Remove BG.

With the lower track selected, CapCut applies the controls to the background or hides Chroma Key altogether. If the timeline still feels unfamiliar, the CapCut editor layout guide explains tracks, the preview canvas, and the clip inspector.
How to use green screen in CapCut Mobile
- Tap New project and add the replacement background.
- Tap Overlay → Add overlay and add the green-screen video.
- Select the overlay clip. Tap Edit → Remove BG → Chroma Key.
- Tap the color picker and drag it onto a flat mid-tone area of the screen. Avoid a hotspot, dark wrinkle, shadow, or green reflection on the subject.
- Raise Intensity until the main green area clears. Stop if hair, skin, clothing, or props start to turn transparent.
- Adjust Shadow and any edge control shown in your build. Judge the result while the clip is moving.
- Scrub the start, middle, and end. Watch hands, loose hair, motion blur, and screen corners.

CapCut's Chroma Key troubleshooting page documents Intensity and Shadow on Mobile. It also confirms that uneven lighting, a poor color sample, low subject-to-screen contrast, and heavy compression can spoil the result.
How to use Chroma Key on CapCut Desktop
Desktop uses normal video tracks instead of the Mobile Overlay button. If the editor isn't installed yet, follow the verified CapCut for PC or CapCut for Mac installation guide instead of an unofficial installer.
- Import both files. Put the background on the lower track and the green-screen clip on the track above.
- Select the upper clip and open Video in the right inspector.
- Choose Remove BG and enable Chroma key.
- Activate the color picker and click a representative area of the screen in the preview.
- Raise Intensity or Strength only far enough to clear the screen.
- Refine Shadow and the edge controls shown in your build, then preview difficult frames at full size.

CapCut's official pages don't stick to one fixed vocabulary. The Desktop panel lists Intensity, Shadow, Feather edge, and Clean up edge. Another official background-removal guide uses Intensity, Shadow, Feature edge, and Clean up edge, while the help article also mentions Strength and Edge Feathering. Go by what each control does and where the control sits in the panel instead of copying a slider recipe from a different build.
How to find Chroma Key in CapCut Web
- Create a blank video and upload the green-screen clip and replacement background.
- Put the background below the green-screen clip.
- Select the upper clip, open Smart tools, and choose Remove background.
- Choose Chroma key, sample the screen color, and refine the visible controls.
- Export a short section first, then inspect it outside the browser.

Because the Web editor uploads and processes your footage, try a short clip on a stable connection before you commit a large source file. The CapCut Web guide covers account, browser, upload, and export checks.
What the Chroma Key controls change
Intensity or Strength
This slider sets how broadly CapCut removes colors around the sampled value. Set the slider too low and green patches stay. Push it too high and holes appear in clothing, reflective props, hair, and motion-blurred edges. Start low and stop as soon as the screen clears.
Shadow
Adjust Shadow in small steps and inspect the subject's edge. Don't assume it can repair severe green spill. When green light has soaked into pale fabric or fine hair, better lighting at the source often helps more than a bigger slider value.
Edge, Feather edge, Feature edge, or Clean up edge
The edge controls change how the cutout boundary meets the replacement background. A small nudge can calm a harsh outline. Push them too far and you get soft shoulders and smeared hair. Check the edge over the final background, since a light halo can vanish on white and stand out on black.
There's no universal set of values. Screen brightness, camera compression, wardrobe, motion blur, the sampled pixel, and the target background all change the result.
Shoot footage that is easier to remove
- Light the screen evenly. Remove wrinkles, hot spots, dark corners, and hard shadows before recording.
- Move the subject away from the screen. Adobe's chroma key shooting guide explains that reflected screen color can spill onto the subject and damage the edge.
- Keep the screen color out of the subject. A green shirt or prop becomes part of a green key. Use blue when green must remain in the shot.
- Keep the subject sharp. Motion blur and missed focus mix subject pixels with the screen color.
- Use the original recording. Repeated social-media compression creates blocky color edges that cleanup controls can't fully restore.
Green reflects more light than blue. Adobe's green screen and blue screen comparison recommends green for brighter daytime scenes, while blue can reduce reflected spill in darker scenes. Wardrobe and subject color still decide which screen is safer.
Make the replacement background fit the subject
A clean edge can still look fake if the perspective and lighting disagree. Match camera height first. Then compare light direction, brightness, color temperature, and focus. A subject lit by cool overhead light won't sit well in a warm side-lit room, even with a clean cutout.
Scale the subject against something recognizable, like a door frame, table, or railing. In a full-body shot, check floor contact and shadow direction. Hold off on color treatment until the edge is stable. The CapCut effects guide shows where finishing adjustments belong without leaning on a filter to hide a damaged key.
Fix the symptom you can see
Green stays in patches
Re-sample a clean mid-tone area and look over the source for shadows, wrinkles, or compression blocks. If the screen shifts color across the frame, one sample may not clear every area cleanly.
A green rim remains around hair or shoulders
Nudge Shadow and the edge controls in small steps. When the rim is baked into the recording, you'll need footage with more distance between the subject and the screen.
Clothing, skin, or props disappear
Lower Intensity or Strength and pick a cleaner sample. When the subject itself contains the screen color, switch to a different backdrop color or combine a careful mask with the CapCut masking workflow.
Chroma Key is missing or greyed out
Select the upper video clip, then reopen Remove BG. Update CapCut and try a freshly imported clip. Recent r/CapCut reports describe a moved Mobile Chroma Key control and greyed-out Remove BG tools, but those posts are directional signals rather than product documentation. I'd start with the official route and the clip-selection check.
The preview looks good but export looks rough
Go back to the original source file, dial back heavy edge cleanup, and export a short representative section. If the export fails, switch to the CapCut export troubleshooting guide. When the app freezes, work through the CapCut crash checklist instead of changing a key that already previews correctly.
Preview the full shot before export
- Watch at normal speed and inspect hands, hair, motion blur, and transparent objects.
- Check the first and last frame. Transitions can expose an edge problem hidden in the middle.
- Compare subject brightness, scale, and light direction with the new background.
- Export a short section and play it outside CapCut.
- Choose delivery settings with the CapCut export settings guide rather than raising every value.
Work in this order: source quality, layer order, color sample, Intensity or Strength, edge cleanup, then export. Raising one slider can't repair a wrinkled screen, heavy compression, or green clothing.
CapCut Green Screen FAQ
Where is Chroma Key in CapCut Mobile?
Select the green-screen overlay, tap Edit, open Remove BG, and choose Chroma Key. CapCut's help page lists Edit > Remove BG > Chroma Key. If the tool is hidden, confirm that the overlay video is selected before you search other menus.
Where is Chroma Key in CapCut Desktop?
Select the green-screen clip on the upper video track. In the right inspector, open Video, choose Remove BG, and enable Chroma key. The controls can be disabled when the canvas, an audio clip, or the background clip is selected.
Is CapCut Chroma Key free?
CapCut's online Chroma Key page currently advertises the core tool as free with no credit card required. Some adjacent cleanup or AI controls can carry a plan badge. Check the badge and export message in your own account before relying on a paid control.
Can CapCut remove a background without a green screen?
Yes. Use Auto removal for an automatic cutout, or Custom removal when your build offers manual brushes. Chroma Key is the more controlled route when the footage has an even green, blue, or other solid-color background.
Why is green still visible around my subject?
Sample a flat mid-tone area of the screen, then raise Intensity or Strength only until the main green disappears. Use Shadow, Feather edge, Edge, or Clean up edge in small steps. Strong spill from a poorly lit shoot may need source-footage changes rather than a higher slider value.
Can I use a blue screen in CapCut?
Yes. Chroma Key removes the color selected with the picker. Blue can work better when the subject wears green, when the scene is dark, or when lower reflected light helps reduce spill. Keep the blue backdrop even and distinct from the subject.
Why is Chroma Key missing or greyed out?
Select the upper video clip and reopen Remove BG. Then update CapCut, restart it, and test a fresh imported clip. If the option is still absent, compare the same account on another platform because menus and rollouts can differ by build, device, and account.
