Chroma Keyer software

What Chroma Keyer software are you using with your HDSLR footage? I got a music video I am currently working on where we shot on green screen with a Canon 5D Mark II for some of the dancers and I wasnt really thrilled about the keyer that comes with FCP 7 so I bought a plugin from Fx Factory called Phyx. That too was a joke. It took the green out for most of the clip but left a lot as well. They also included a few other filters to help with removing the green but they didn't impress me either. On some of my clips, I had to use a 4 point garbage matte and a mask shaper just to get the remainder of the green out! Talk about being annoyed that I spent almost $200 for a keyer that didn't live up to its name. Now I am wondering if I am having these issues because we used a Canon 5D. The screen was evenly lit and the performer was placed about 6 feet from the screen. Some of the keys came out looking really good when I dropped in the animated background, but I have more clips that look bad than good after they were keyed.

Someone mentioned I use Keylight since they make it for FCP too but I am worried that if I go and spend the money on that if I will have the same results of it not being able to pull all the green out like they say that can do.

Your thoughts?

There could bf numerous reasons why you are bit getting a good key, but you shouldn't expect any keyer to be a one click solution. Keying can be an art in itself. There is a great article here on the cow which firms the basis for all keying I do. Although the article explains how to do thus in after effects, the principle applies across the board.

I find that I end up using many different keyers depending on the footage. Different settings are needed to keep nice detail and for the core matte and for dealing with troublesome areas.

I've been using Keylight in After Effects for any kind of footage for a quite a time now, and it produces great results.
You have to work yourself into the numerous settings, but it's worth it. You'll find a lot of information on keylight here on the cow.
