Hmm, i'm not really understanding what difference using a png generated from photoshop or AE makes, even if it is a movie file that is 1 frame long i cant see any difference in the quality of the edges.
+i've read up a little on 72dpi video. Every link i've looked at seems to say that 72dpi doesn't relate to video atall + that its the pixel count that matters. I'm more confused now than i was before
Would anyone else like to share their mask creating workflow aswell?
