They can design anything on the screen from settings of a medieval village to animated weather maps you watching during the weather report.
How Does It Function?
This particular process requires and takes the digitally transferred film or recorded video through a computer output or video feed. As soon as the video reaches the video feed, technicians will remove a green color based on the region of the spectrum you wish to achieve.
In most cases, people are using bright green or blue, because these colors differ from human skin tones and you will not be able to find them in clothing, which means that you will not affect the actor by removing the background.
Have in mind that if you wish for this effect to function, you have to evenly light it and try to keep it away from shadows, especially if you are doing it professionally. As soon as green screens are identified and removed, you will be able to implement anything you can imagine.
