Is there a difference between green screen and blue screen in film stunt shooting?

The difference between green curtains and blue curtains;

1, color difference: blue curtains are blue curtains. Green curtains are green curtains.

2. Advantages and differences:

(1) Green screen: The fluorescent green used in the computer system is easier to separate from the foreground, and at the same time, it is brighter and less prone to black edges. The noise of the blue channel is the most serious, and the mask edge after blue screen keying is noisier than that after green screen keying.

(2) Blue screen: Because blue is the complementary color of human skin, it should be the easiest to cut the image with a blue screen as the background. The green channel has less noise than the blue channel, so the edges of the green screen keys are smoother.

Note: whether to use the green screen or the blue screen as the key depends on the color of your subject first. If there is a lot of green in the foreground, then I will focus on the blue screen. If there is a lot of blue in the foreground, we will shoot on the green screen.

3. Application differences:

(1) In Europe, green screens are generally used.

(2) In Asia, blue screens are generally used.

Reason: Most Europeans have blue eyes. If you use a blue screen, it is easy to gouge out the actor's eyes later.
