The problem I'm having comes when I export from FCP. if i export a self contained video, no problem, but giant file size. I want to export a reference file so i don't have the enormous size video. however, throughout the reference file video, there are slight changes to the brightness of the video. These are in random spots too. Check out the sample video of what i'm talking about. Any solutions? Suggestions?

FWIW, I've given up on reference files. I bought more storage and only export to self-contained files. Even so there are occasional trouble spots.
