I have read this thread and can say I am having all of these same issues. I use the Black Magic Intensity card and thought it was that at first & then started to realize that it was happening mostly to the RED 2k proxies. I have 2 512mb video cards and am still trying to figure out if it’s the video cards, the Intensity card, the RED proxies, or just straight up Final Cut.
One thing that helped me was changing the sequence rendering to “Always RGB”………it seemed to fix a lot of the issues, but I still get green flashes here and there.
I’m using:
Octo Mac Pro
2x Nvidia 8800 Video Cards
8gb RAM
Black Magic Intesity Card
If anyone has any other advice……..I’m all ears!!!……..Thanks!
