Again thankyou for the reply Graham. I can’t test this out know as im on another computer. But will try exporting using YUV and RGB codecs to see the difference (at a guess i would say that FCP is keeping the signal within a 16-235 range on export to animation RGB codec). However this contradicts what your saying in your article that FCP only affects still image import and export and not video rendering (import/export). But i’ll give it a go and report back.
