I’ve avoided running mavericks on all of my systems, for now. I’m still running 10.8.5, so unfortunately, I can’t test that out for you. Anyone else running controllermate on mavericks with any success?
Preconforming will take a flattened QuickTime (even with dissolves) and slice it up based on an EDL. However, since you’ve already graded it, that wouldn’t do you much good. I think recreating the dissolves in resolve is you best bet, but if it comes up again, I’d use the preconform workflow if possible.
