Keylight is an industry-proven blue/green screen keyer. The core algorithm was written by the Computer Film Company and has been refined on scores of films. It is simple to use and is particularly good at tackling reflections, semi-transparent areas and hair. Because spill suppression is built-in, often selecting the screen colour is all you need to do to pull the matte and seat the foreground into the background so it looks photographed rather than composited.

Keylight 1.2v10 is bundled with AE CS4. Keylight (1.2v1 and 1.2v2) for After Effects 7 is no longer actively developed and will not be supported from November 2009.

Keylight is fully floating point for use in 32 bpc projects and comes with a suite of tools to erode, soften, despot and otherwise manipulate the matte should the need arise. Inside and outside masks are supported. Separate colour correction, suppression and edge correction tools are also included to fine tune the result.

Keylight has been used on scores of films including: Harry Potter and the Chamber of Secrets, Die Another Day, Blade 2, Resident Evil, Harry Potter and the Sorceror's Stone, the Beach, Notting Hill, Sleepy Hollow, Chicken Run, Lost in Space, The Hudsucker Proxy, The Truman Show, Armaggeddon, The Big Lebowski, Mission Impossible, Last Action Hero, The Saint, Strange Days, Little Buddha, Waterworld, The Quick and the Dead and many, many more.
