I've been seeing for a while some intermittent, but very prominent pixelation occuring on seemingly random clips when I go to export a completed project.
The footage was shot with a Canon 5D MkIII, and I need to export to Apple TV 3 1080p 23.976. I've tried several different options (different output file-types, exporting it uncolored, and bringing it back in...) but it's continued to appear pretty consistently.
I'm not sure what attributes of a clip/effects cause it to appear on some and not others, but it's pretty frustrating!
What information about my computer/set up is best that I provide in order to get feedback for how to resolve this issue?
