How big is the green screen for recording micro-lessons

The size of the green screen depends on the size of the shooting material, and there will be no problem of blocking the material when the material is put in.

Both the blue screen and the green screen are background screens for shooting special effects shots. Actors perform in front of blue and green screens and are photographed by cameras. The picture is processed in the computer, and the blue or green background is removed and replaced with other backgrounds.

Blue is the complementary color of human skin color, and it should be the easiest to handle with a blue screen as the background. In recent years, the green screen is more used for stunt shooting, but the fluorescent green used in the green screen is easier to separate from the foreground in the computer system, which is brighter and less prone to black edges.
