Chroma Key Plugin/filters????

I did a green screen shoot back in my FCP 3 days. Had a tough time keying then, but I was given info about a plug in that worked GREAT. (I believe it was free...)

Anyway, I'm in 4.5 now and just did another Green Screen shoot and I'm finding the Chroma Key good, but not as good as that old filter (I no longer have...)

Any suggestions on what the latest cool filer or plug in is that works wonders with keying out Green Screen????

Thanks in advance. Couldn't find anything helpful in the archives. But if you have a link, I'd appreciate.

I found a great article and some very good tips.

4.5 does have teh Smoothing 4:1:1 filter and that was what I was looking for.

Thank you
