I have very,very nasty problem here and can't solve it.
We are recording on purely white background our collegue, put the video in FCX, and then add some titles on generated white background (or pure white .png).
Well, everything's ok in the final cut... horrible things happen after rendering.
My white background from recording is still perfectly white.
But the white from generated media is 252, 252, 251. And you can see that some of the white background is a little darker.
Why is it happening and what I should do to avoid that?
I've tried similiar thing in for example vegas - i have all ideal white background with smaller files... what's the point for FCX?
