perfect matting in PP
I need to shoot a woman with back lit white translucent hair in one location and composite her into a new location. Can this be done visually perfect in HD and PP2? I’d prefer to not use uncompressed codec but can use the component video out of my Sony Z1. Of course the subject and backgroud would have identical lighting, camera height and lens setting, distance, etc.
In past I’ve done this with a green screen in DV NTSC but it was never convincing (little green fringing and or softend transitions on the head and shoulders. I suspect this is caused by the 4:1:1 DV codec I had to use then. Can I expect success ? Do I need special plug ins to do
a perfect matt like Ultimatte? Any advice would be appreciated. -

Just wait for the CS3 release, since it includes Ultra, IMO the easiest and best chroma keyer there is.

Green fringing is almost always caused by green spill. If you flat light the background, and use good three point lighting on your subject, and maximize the distance between green screen and your subject, that helps eliminate the green fringing. DPs tend to forget about the importance of backlight when up to a green screen, but the lack of it, is a stopper. Also a good keyer like CS3 will ship with – definately helps. However if you can’t wait, try the lighting. 2.0 is capable of a pretty decent key.
