Overview of the Chroma Key technique:

The Chroma Keying technique is used in video/cinematic effects to remove a green or blue background, often called a 'Green Screen' or 'Blue Screen'. This technique is also known as color keying, colour-seperation overlay or simply as Green Screen and Blue Screen.
