What is Green Screen?

Chromatic keying is the process of overlaying footage over a different background by using a green screen as a backdrop.

Colour keying, or chroma keying, are all terms used to describe this process. 

During this chroma key process, the green screen isolates actors from bright green backgrounds, which are replaced during the postproduction process. By focusing on the green value, editing software removes it, isolates the actor(s), and then replaces it with an isolated

Different Types of Green Screen

Although blue screens are also used as de facto industry standards, green screens are currently the standard since green is also distant from human skin tones and is relatively less common than blue in costuming and props. As a result, no colour in the shot can be the same as the background when using chroma keying-if; for example, if the character’s shirt is green, the shirt will be removed from the shot and replaced with the background.

In addition to films, green screens are also used frequently in television newscasts (mainly when showing the weather map in a weather forecast), video games, and music video production.

Why Is Green Screen Used in Film Production?

Green screens can depict disparate locations and sequences as they remain within a soundstage. Filmmakers use this technique for a wide variety of purposes in Hollywood, often dealing with special effects. Among some of the possibilities:

  1. The idea is to make it appear that two actors were on screen simultaneously when, in truth, they were filmed separately and then combined using chroma key.
  2. Enlarge or shrink a character relative to their background.
  3. Move characters to animated or computer-generated backdrops.
  4. Make actors appear to fly in a superhero film.
  5. Transport characters back through time, or into difficult-to-film environments like outer space.
  6. Place actors into seemingly life-threatening situations like a pit of snakes or a balanced on the lightning rod of a skyscraper.

What Are the Advantages of Green Screen?

Filmmakers can do pretty much anything with a green screen as long as they put forth the effort to ensure that it is done correctly. The biggest advantages of using a green screen are:

  1. Producing scenes that expand the possibilities and language of filmmaking.
  2. The use of green screen technology can help actors remain in the studio and away from the dangerous environments they are supposed to portray.
  3. Even if they filmed the scene separately, actors could appear on screen together. This helps with scheduling.

What Are the Disadvantages of Green Screen?

Green screen use is challenging and also presents some considerable disadvantages. These include:

  1. The technique appears artificial and off-putting to audiences if the lighting is not perfectly balanced.
  2. Despite being cheaper than practical sets, this process is still time and labour-intensive, cumbersome, and expensive and not ideally suited for independent films or low-budget productions.
  3. If the foreground footage contains any background colour, it will be replaced during the keying process.
