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??
