ABSTRACT
Green screen (or blue) is a nickname for the technique traditionally known as a traveling matte composite. The technique takes advantage of using color backgrounds to use any process that will remove that color and replace it with a different image. Any slight changes in the brightness and darkness of the green screen make the job more difficult. Blurring will reduce the number of colors and details the screen has. For the best result, one should create two three-point lighting setups: one for the actors and one for the green screen. Motion Blur is an effect that one can enable from the time line that creates the appearance of how a camera responds to movement. Shot setups that include a television are a common problem. If the TV is on, due to interlace technology, the camera will distort the image and a black bar appears on the screen.
