On your phone
- Open your project with your main video.
- Tap Overlay → Add overlay and pick the green-screen clip.
- Stretch it to fill the frame, tap it, then Remove BG → Chroma key.
- Drag the colour picker onto the green, raise Intensity until it disappears and add a little Shadow to soften edges.
On desktop
- Drag the green clip onto a track above your video.
- In the Video panel open Remove BG and enable Chroma key.
- Pick the green with the eyedropper and adjust strength and shadow.
Fixing common problems
- Green fringe around text: nudge intensity or shadow up.
- Parts of your video vanish: your footage contains similar green — export the overlay on a blue screen.
- Overlay in the wrong place: export it in the same format as your video (9:16 for Reels, 16:9 for YouTube).
Free green-screen overlays

Frequently asked questions
Does CapCut support transparent video?
Most phone editors don’t, which is why a clean green screen is the most reliable option.
Green or blue?
Green by default; blue when your footage has green clothes or plants.
Does this work in InShot or Premiere?
Yes — InShot has a Chroma tool for picture-in-picture clips, and Premiere uses Ultra Key.
