What is Chroma key?
Chroma key is a visual effects technique for layering two video streams together. The most common example of Chroma Key is the weather news. The weatherman is not actually standing in front of weather map, he is actually standing in front of a blue or green screen. The blue or green background is digitally removed and replaced with the image of a weather map.
