Strange thing happened. I opened a project I was working on a week ago and my preview was horrible, very pixilated. I usually work with my preview set on Preview (Auto) and I get a good preview with minimal pixilation, but now it’s bad. Also I have a few people in front of green screens and no matter what preview I use “Preview (Best) for example it does not filter out the green, but if I render the timeline its fine. I think I must have change a setting or something. I restored all project settings back to default and the preview remains bad.

Has anyone had this problem? Your comments will be much appreciated.
