Why do people like to use the green screen as the background when making movies?

If you are a fan of Marvel Comics, you must know that most scenes of Marvel Comics are there? Green cloth? I took it before. The actors shoot in front of the green set and then add special effects, which is a spectacular scene we saw in the cinema.

Do you know why the green background is used in making movies?

Visual effects and animation

The running, flying and fighting scenes of superheroes in movies are not real. Only with special effects can they have such a cool picture.

After shooting video in this way, you can replace the green color in the background with any image or video in post-production, and use the key technology of chroma to simulate the flight and battle of superheroes.

Chromaticity key is a kind of visual effect technology widely used in post-production, which superimposes images and videos on color-based images or videos.

It can make the specified color become. Transparent? , and in? Transparent? Region inserts a specific background or animation.

With the rise of animation in the field of film and television, this technology has become a gold mine for digital graphics experts and designers in the film, news broadcast and video game industries.

According to the requirements of graphics, it can be used for many purposes, but it is mainly used to delete and re-edit the real background and replace it with another image or material.

For example, in the weather forecast TV program, the host stands at the front desk, and the background has almost no characteristics, while when shooting the weather forecast, the background has a big green or blue screen. What is the background in post-production? Transparent? , with maps and various animations.

Why use green in particular?

Theoretically, when using color key technology, this function can be used for any color, but green is not necessary.

The higher the color purity, the easier it is to type, so blue can also be used as the background. The background of many weather forecasts is blue. But in practical application, green is widely used.

The most basic point is that people's skin is not green, and green things are rarely used.

People's skin color and clothes are not green, so it can provide a better contrast between the subject and the background, and it can be easily adjusted without affecting other elements of the picture.

Another reason for using green is that the brightness of green is very high, which makes the green screen very bright and saves lighting for lighting engineers.

The use and popularization of green screen involves almost all fields related to virtual media, from education to any information field that needs more immersion and attraction.

Heroes like Iron Man and Spider-Man wouldn't be so cool without these huge green screens.
