exported ProRes 422 from FCP to get rid of the green screen, but now i can't bring it back with the alpha channel ( need transparent background ). Should i choose 444 or another codec? what do i do?

ProRes 422 doesn't support alpha channels. In the ProRes family of codecs, only ProRes 4444 supports alpha channels, and theat's the one you should use.

Don't have it? Try QT's PNG codec.

thank you sir, that semi-worked. Now for some reason the background color tints the subject. It was professionally shot but if i get rid of the green completely ( using clip black ) the subject becomes a bit transparent and the background comes through and also shows edges of mask. In comp settings there's no way to unselect background :(
