Hi there!

I am experiencing the same issue.
I don’t think it’s the computer, I think it’s some kind of bug in FCPX with R3D footage.
First, I thought it was freezing because of the external storage unit, my footage was on.
But after moving the whole thing, I started digging and found your thread.
I am working on an iMac Pro, 128gb RAM, 18 cores and the best graphics card, so I’m pretty sure it is not a hardware related problem.
I also work with 4K R3D footage, trying to put on the Flow transition.
When I changed the view to proxy, it worked just fine, but I really want to export in full quality.
The Apple customer service was no help at all, for he did not even know what R3D footage was…
I hope someone will fix this issue.

Sorry to open this back up, but I thought maybe it is of interest for you guys.
Or maybe you came up with a solution?

Regards,

Benjamin
