​The Chroma key processor is a great design that supports Video or S-Video as the main source and the other Video or S-Video input as the background source. The background sources along with 6 background colors chroma key effects. The main source can stand in front of the background source and using the chroma key to take off the background colors to perform the different color effects. Also, using level adjust knob to control the color effect levels.
