I have a lot of footage shot on DV tape using a PD-170. I have usually used FCP 4.5 to do my keying with average results. recently i got after effects and have started to use the Keylight(1.2) plug in. its controls are good, but i am having a lot of trouble getting rid of the severe edge pixilation. am i missing something here, i have been through a few tutorials and although my original footage doesnt have the best edge lighting on FCPs keyer it is much better than keylight??
I prefer FCP's keyer. I don't know that it's more powerful than Keylight, but I'm just more used to FCP's, I guess.
You will probably have to put up with some amount of green fringe because DV is probably the worst format you could use for keying.
What helps me sometimes is to generate a grayscale mask of the key, then apply some blur and levels/threshold to re-sharpen the edges and make them more smooth curves instead of pixelated, then apply that as a track matte in FCP. That gets pretty complicated though.
