Green Screen for Chroma Key
A chroma-green surface requested from the browser as sRGB #00B140 for video matting, OBS keying, and small tabletop shoots.
Open tool fullscreen →Interface and local controls remain in Portuguese.
How to use
- Open the tool and enter fullscreen mode.
- Position the display behind the subject with dedicated frontal lighting.
- Configure the Chroma Key filter in OBS Studio or your NLE editor and adjust threshold tolerances.
When to use
- Clean chroma key backdrop for macro product reviews and unboxings.
- Self-luminous green background for compact webcam streaming setups.
- Rapid compositing in DaVinci Resolve, Premiere Pro, and CapCut.
Limitations
Active displays emit light that can cause green spill on nearby subjects. Maintain physical distance and calibrate brightness.
Frequently Asked Questions
- Why is green commonly used for chroma key?
- It often separates well from skin tones, and many camera sensors sample green more densely. Results still depend on the camera, compression, lighting and subject.
- How do I reduce green spill on reflective objects?
- Increase subject-to-screen distance, lower brightness until the key is stable and light the subject separately while checking the camera preview.
Technical Methodology & Display Science
#00B140 is a nominal CSS reference. Colour management, profiles, brightness and panel characteristics can change the light recorded by the camera.
Cameras and platforms may reduce colour resolution or compress video. Spill, moiré, banding, reflections and focus on the pixel grid can all weaken the key.
A screen avoids fabric folds but does not guarantee uniform output or remove shadows. Check exposure, distance, foreground lighting and key tolerance in the captured image.
