Thought I’d update this in case anyone else has the same question.
It doesn’t seem to matter that the .rdm subfolders, .rfc and .profile items are missing. I simply copied all the R3Ds into a new folder on my external drive. From there, I made _p.mov quicktime proxies using REDAlert. After import, drag them to a ProRes sequence and render.
I attempted working in a REDCODE sequence, but this was causing serious scaling on the slo-mo footage, and I was unable to add any basic effects (the entire clip would grey-out after render).
I imagine I wouldn’t have to render as much if I’d transcoded to ProRes, but it’s a bit late for that now and the _p.mov proxies seem to be working fine otherwise.
Hope that helps someone!
