i can’t upload a picture but il try explaining again its like art effects on the hair only on the hair,rest of the body+arm got no problems,its a cause of the chokker or the keylight? i heard that maybee there is another plugin which can fix the problem…hair colour is black.

well i know all that ,thats why i come to this forum
iv searched the manuall and done few tuto’s but still what im looking is for some tips maybee some plugins or some effect i can apply and continu from there till i get a good result.

Most likely you are screwing your Alpha by shifting the grey levels at some point. In technical terms you are enforcing some bright grey levels in the Alpha to be used as white without having compensated for it so you get holes. You usually don’t see that at first sight, but if you view the matte channel, it should show up. Try to adjust your Rollback parameters in Keylight. Don’t use the Matte Choker, it only intensifies that problem (it is not a very subtle tool compared to Keylights built-in tools).

okie first of all thanks …we’r makeing some progress to what im trying to say,im still at work so i can check only later but from what you said
i can tell you that i chceked the alpha channel at the views of the keylight
and its white no holes in it and as i said its only in the hair ,rest of body
+arms are good ,in the top of the hair/sides of hair there are some glitches or whatever dunno how to call them ,some distortion of something..
but the alpha channel is good with no holes in it. -
Mmh, distortion? That would mean it was in the original footage somehow (block artifacts or digital flicker) or you are using some crooked footage settings or time remapping. No idea where it would be coming from otehrwise.
