I used cs5 ultra key on my green screen filtering project.
applied everything from the adobe tv tutorial. now my problem is,
since i have a pretty bad lighting done i have this pretty bad shadows.
but i was able to get rid of them by tweaking the parameters on the ultra key effect.
after having that fix now my main prob is the edge of my subject flickers and it's very edgy.
I tried correcting them in the matte clean up option tried to smoothin the edges, but the flickers
are still there and the smoothing is very obvious that is so not natural.
Infos: my video is from a d90 camera set to 720p recording and im editing it in my macbook black 2.4 Ghz with 128 mb gpu (i guess)
My Background used by the way is a White Matte, so the detials on the edges are very obvious.
Did you found a solution for this ? i have exactly the same problem... I think my problem comes from the video, the focus is not exactly on my subject...
