Thanks Chris for your kind reply.
I don’t do this professionally, but I understand that what you get out of a calibrated broadcast monitor cannot compare to what you see on a regular LCD computer display and that this is the only way to go when you are producing broadcast material.
Still it baffles me to think that apple would produce a product so tightly integrated with QT and that works properly only under such demanding work conditions. Does this mean that if you install FC on a computer your QT’s will never look like what you see on FC, unless you hook up a very expensive video system to it? I find that hard to stomach.
Anyways, I’m not here to debate one thing or the other. To me is clear I have a problem on my work flow and that FC and QT are not talking to each other correctly. By now my only practical solution is to continue watching my exported clips via VLC.
I have attached an image of how things compare among FC and the 2 players in mention if anyone wants to look at it.

Thanks for all the feedback.
