I haven't had issues before rendering, but now certain filter effects are causing the output to have a reddish or greenish cast, and looks to include some sort of checkerboard pattern over the movie. Very ugly. It's even doing it on files that previously rendered fine. It happens in both FCP and Motion. Also - at the same time the default gray background in photoshop is now an ugly green. I'm guessing it's either a system setting or corrupt file or something to do with the video card (files look funny on different monitors as well) Any ideas on how to fix this? Sound familiar to anyone? Any help would be appreciated- thanks!
