About Chroma Key

The most common application of Chroma keying is on the evening news, when you see the weatherperson standing in front of a weather map. Actually, he or she is videotaped standing in front of a green wall while the weather map is contained in a separate video feed. To combine the two, the video editing program at the TV station eliminates the green background and superimposes the weatherperson over the video containing the weather.

Studio 10 works the same way. After getting the two videos properly placed in the Timeline, you tell Studio Plus which color to eliminate from the Overlay video, usually either green or blue. Then Studio Plus superimposes the video that wasn't eliminated into the Background video.
