5 Functions of Green Screen in Filming

When watching a movie, we will be presented with a visual appearance that catches the eye. For example, a movie scene depicting someone who is adrift in the middle of the ocean in tense weather conditions or someone who is climbing or climbing a building. Everything looks real. However, is it true that the scene took place in real or use certain effects?

In the process of making a film or video, there are usually a number of scenes where the process of shooting is done in the studio. In the studio, the actor performs certain scenes according to the script in front of a large curtain green (green screen) or blue (blue screen) as the background. When entering the editing process, this background is then replaced with another image or color according to the text using the Chroma key technique. Chroma key technique is a technique of combining two images at once made with a video camera. From this combination, the background color of an image is removed and replaced with an image or other color.

Therefore, what is meant by green screen?

Green screen (or blue screen) is a curtain or green screen (or blue) that is used as a background in the process of making films or other visual communication practices. The purpose of using the green screen itself is to facilitate the editing process by adding background, characters, or other images.

Use a blue or green screen as a background in the process of shooting in the studio because the two colors are seen as not resembling skin color. However, between the two, the green color screen is the most widely used in making videos or films. This is due to the increasingly widespread use of high-definition cameras by users. In addition, compared to blue, green is easier to illuminate with artificial lighting so that the light needed to illuminate green is not much. Savings in film production costs can also be reduced primarily related to lighting and installation.

Then, what is the function of the green screen in the process of making films?

In making films, green screen has several functions, among which are as follows.

  1. Change the background

Green screen is a large curtain that becomes the background of the subject when the shooting process is done. This background will later be removed and replaced or combined with other images or colors also taken using a video camera in accordance with the demands of the film script. (Also read: Duties of Film Producers – Function of Artistic Procedures in Film )

  1. Creating illusions for film players

The existence of this green screen requires film players to imagine for themselves the setting desired by the director to refer to the film script that has been made. They must be able to imagine being in an actual location such as palaces, terrain, open sea, high cliffs, and so forth. Of course this is not easy because of the lack of property in the studio. (Also read: Crew Duty on Film – Backsound Function in Filming )

  1. Creating certain visual effects

The function of the green screen in the next film making is to create certain visual effects. This is closely related to filling the background with other images according to the film script. After being filled or combined with other images, a visual appearance will appear more alive. For example, someone who survived an explosion and burned a building and that person walked away from a burning building. Here, the background is a massive explosion accompanied by a burning building. While the actor who is the subject is in front of him. (Also read: The Role of Script Writers in a Film – Storyboard Functions in Filming )

  1. Facilitate the editing process

Green screen also functions to facilitate the editing process. As we all know, the main purpose of using a green screen is to highlight the main object while blocking the background so that the editing process is easy. Editing using green as separating the background with the main object or when neutralizing, green is easier to edit than blue. (Also read: Management Functions in Film Production – Composition in Cinematography )

  1. Savings

The function of the green screen in the making of the next film is to save on film production costs. This is because some shooting processes for special scenes are done inside the studio and not outside the studio. But there are also some shooting processes that are done outside the studio by using a green screen but not in the actual location. For example, the film John Adams who made the process of shooting outside the studio but not at sea actually as we see in the film. (Also read: History of Indonesian Film – Stuntman Function in Film )
