I already own, Final Cut Studio 2, which includes Motion 3 and Final Cut Pro 6 has a keyer, and I also have After Effects CS3, I will do some green-screen work, and need a good keyer, should I get composite lab? Or do I have enough for keying?
I'm actually going to say that you shouldn't get it. I own it and love it, but its painfully slow on my intel mac. It might be a good option if you had one of the last generation quad G5's, but if you are running intel its not worth it. Especially when you have after effects, which I assume has a good keyer.
