well, first i used keylight i messed around with the screen matte settings: output black/white. Put screengain to 110 i think. And i auto traced it. Hope thats enough info
I also tried to key this footage with premiere pro 2 and used all kinda stuff like offcourse chromakey,greenscreen key, roughen edges, levels and some more. But with AE i get slightly better results.
I can accept the bad quality picture but the edges are killing me, the pic needs to stay still if you know what i mean.
