Additionally I'd say the colours look nothing like Velvia 50 either. I shot on Velvia for a number of years, and this really doesn't look like it. Sorry!
Can you help me understand what you are trying to do here? You are passing a DNG through resolve as a way of simulating a filmic (stills) look, in this case, Velvia? It seems a roundabout way of doing things if that's the case. What's the benefit?
