sorry to be so confusing!
basically i am trying to do greenscreening. i’ve tried with keylight and all the keyers in AE but none of them give me a good key…i get lots of jagged edges that aren’t smooth. i’ve tried softening but you have to soften sooooo much to get a good edge that i’m losing to much footage!
so i thought i’d try a different way to create a matte that i could use for the composite. this is where i thought the sin city effect might come in usefull. i have taken my footage and made it black and white except for the greenscreen, which i have left a bright green. is there any way i can use this footage as some kind of luma/sat/hue matte with my original footage to get a good composite?
hope i’v made a bit more sense now!
