My Experience With Keying
While I wouldn’t necessarily refer to myself is a “Green Screen Guru”, I have my share of experience with pulling color based keys. For me is started on a Grass Valley 200 switcher in the late 80’s with the little spinning knobs you used to select and finesse the color. I remember that little chirping sound it would make as you went from one limit to the other. Just thinking about that switcher really takes me back.
In later years I worked with a Ultimatte 45 external hardware box that allowed you to pull great keys using a component signal. At the time it was a $35k box and the place I was working at would only rent it when we had a project that required it. Sometimes I would run it as part of a studio shoot to check keys as we went, but most of the time it was setup in the online suite I was in.
The difficult part about using this box was that the first few times I used it I only had a few short hours to actually learn the box. As soon as it showed up I would pull out the manual and start reading so that I could at least appear to the client that I knew what I was doing!
Years later we have tools that are so much more powerful right on our computers, and they cost a small fraction of what the original Ultimatte did, or in some cases come free with editing and compositing software. FCP Studio has some ok keyers included, but Primatte inside of Motion is actually pretty good. And AfterEffects has KeyLight, which I find to be the best blue/green screen keyer out there for what I do. It’s rare that I can’t get a good key out of keylight regardless what I throw at it.
