Under “Screen Matte” go to “Screen Despot White”. you’ll find a selection called “replace Method”, choose “Hard Color” and see what that does. It cleared my chunky video right up.
I seem to be good with my updates. It’s done it since day one with this CS5 version. It’s got some other weird problems too that I don’t like. Sometimes it drops the audio off a spot when it renders or commands don’t respond.
This version used to run properly on this machine, but somewhere in it’s history it was deleted or fiddled with and I just can’t figure out why it’s not working now. Seems like re-installing would take care of it.
Thanks for the reply!
