Welcome to Chroma Key Tv
  As our name says, this site is all about Chroma Key; "The process of overlaying one video signal over another, the areas of overlay being defined by a specific range of colour, or chrominance, on the background signal" (Quantel Digital Factbook).
On this site we've collected information, content, software, and links to other relevant Chroma Key resources. The Litering is a component of the Chromatte system, it is the ring of LEDs that shines onto the material. If there is any additional information missing from these pages that you think is relevant, please feel free to send an email to
What is an Ultimatte?
  The Ultimatte is the predominant chroma keyer in the industry for good reason. The unparalleled chroma keying capabilities of the Ultimatte make traditionally hard to chroma key objects like hair, fur, smoke, glass, and semitransparent cloth easy to chroma key. Spill suppression is another reason for Ultimatte's success, it can remove the colored light that bounces of the chroma key screen and onto the talents shoulders and hair. Ultimatte has both live and post production chroma keyers; The Ultimatte 9, the Ultimatte 10, and the Ultimatte 400 for live, and AdvantEdge for post production  
What is a Virtual Set?
  A virtual set uses green screen keying to create a set or stage that isn't real, and in some cases could not be. Virtual Sets are ideal for situations where a real set is too expensive because of either space, location, or materials cost. Building a football stadium would be very expensive. Building a football stadium made of gold on the moon would be impossible, but not with a virtual set. A small stage covered with green screen and adequate lighting is all that's needed to put your talent anywhere your imagination wants to put them.
