I am trying to get my head around the Keyer in Shake. My background is Discreet Flame, and I feel very confident with their Keyer (Modular keyer as well as the new Master keyer) The result I am getting from the shake keyer (Keylight and Primeatte) is not something I am proud of 
!
Having said that I need to spend some more time learning them, so it is unfair for me to judge them this early on...
I know there is also the Ultimatte/AdvantEdge keyer.
What is your experience with the different Keyer and also if anyone has used booth shake and flame/inferno keyers?
Are there any other 3rd party Keyers out there?
