Chroma key overlay, most likely chroma key, is a visual effect and therefore a post-processing technique for compositing (overlaying) two video or image streams based on hue (color range). This system has been used in many professional fields to remove the background of a particular object from a photograph or film, especially in broadcast news, motion visualization and the film industry, and video games. The color area in the foreground frames is always made transparent, which allows you to insert separately captured frames of a track recording or a static image into the scene. The chroma key technique is commonly used in video production and post-production. This method talso called Color Keying, Color-Separation Overlay (CSO; just BBC) or other terms for some Color Keying Color-related types such as green screen or yellowish screen; The chroma key can be done against any color that is uniform and distinct, but dark green and blue are the most commonly used as they differ the most in hue from any human skin color.

Porter in The Great Train Robbery used double exposure to add whimsical scenes to windows that were dark during filming on set, and exposed most of them with only functional frosted glasses.

He is credited with ensuring that Larry Butler, the scene with the worker genie escaping from the bottle, was the first use of the true blue screen process to create an airplane travel mat for The Thief from Baghdad (1940), which won the Oscar for Best Special Effects of the Week . In 1950 withWarner Brothers employee and former Kodak researcher Arthur Widmer began working on a traveling UV matting project. He also began to develop blue screen action: one of the first films to use them in a positive way was a 1958 variation on Ernest Hemingway’s short story “The Old Man and the Sea” starring Spencer Tracy. 
How was blue screen made?

Rybczynski Zbigniew also contributed to the fact that you can use the blue screen technology. A printer optics with five projectors, a camera and a functioning “beam splitter” were used to insert the actor along with the background material ohm frame by frame before a random blue screen. In the early 1970s, American and British TV stations began using a new background instead of blue for one-person newscasts. By the 1980s, minicomputers were definitely being used to visually control the printer. For The Empire Strikes Back, Richard Edlund built a nice solid “square optical printer” that made the program much faster and saved money.
