Linear scans in Resolve

I have 2k linear DPX scans I want to color grade. I can't play them back in real-time though. I want to convert them to ProRes4444 HD files. What's the best way to do that? They are 16-bit right now. Do I need to put them through a LUT to properly convert them to Rec709 aka properly gamma encoding the files so I retain all the proper bit depth when I go to HD?

Converting them to another color space will probably clip them. You should just convert with no LUT.

Realistically the scans are probably 12-bit in a 16bit wrapper, as not many CCD's or CMOS sensors go beyond 12-bit linear. I would just make a flat pass unscaled render to ProRes444 which is a 12-bit capable format.
