Alright...

I've been testing a clip with REDCineX exporting to ProRes422HQ. It looks great in FCP (same ProRes 10bit 444enabled settings as above), with the same gamma and saturation I set up in REDCineX. So I next tested a send to Color. It looks great in Color too. I adjust and render, send it back to FCP. Still looking great.

Then... I export a self-contained QT using current settings, open it in QT7 and it looks washed out and a bit too grainy and posterized than ProRes422HQ should look. It's like I'm right back where I started before the adjustments above which cleaned up the ProRes export for me.

Just to check, I then open the same clip in FCP and it looks great.

What is going on with QT7, there is some sort of Gamma inconsistency going on, but I definitely have FCP color compatability enabled. I was running REDCode QT Codec v3.9, but I just updated to QT Codec v4.2 to see if there was any improvement... But there is no improvement.
Just as worrying is that I'm still noticing the 'drifting' frame stutter issue.

Can someone please help me understand what is happening?

I found several examples of what I think is the same or very similar issue with washed-out ProRes in QT on the REDuser.net forum, but none of it is really helping me find a solution...

Thanks for your help so far, I just hope you're still with me.
