Click the screen color in the picture, adjust the range and the soft edge while watching the live preview, then choose a new background color or picture. The video never leaves your device. It is read and saved by your browser, so there is no upload, no queue and no copy on a server.
Green screen (chroma key) works with any evenly lit, single-color background: a green screen, a blue sheet or a colored wall.
How to remove a green screen from a video
- Drop your video on the box above.
- Press “Pick it from the video” and click on the green background.
- Raise Range until the background is gone, and use Soft edge to smooth the outline.
- Choose a background color or picture, press Replace background and download.
Getting a clean key
Even lighting on the screen matters most: shadows and wrinkles make patches of a different green. Keep the person a step or two in front of the screen to avoid green light spilling onto them; the tool also removes some green spill from edges.
Range and soft edge
Range sets how close to the key color a pixel must be to disappear. Too high and parts of the subject vanish too. Soft edge blends the outline so hair and edges don’t look cut out.
Questions
Can I get a transparent background?
Not yet. The background is replaced with a color or picture.
Does it work with blue screens?
Yes, pick the blue in the picture.
Is it slow?
Every pixel of every frame is checked, so expect roughly the playing time of the clip on a laptop.
