it's durn hard to get the hard information. So for some users, a 1-2-1 NLC tag would simply get the correct view.Īnd I'm told there's not many systems where the 1-2-1 tag is a problem, fewer than where 1-1-1 is a problem.īut. On most systems that show 1-1-1 as 2.2, the "other" or "2" tag will cause the system to apply gamma 2.4. On some systems though, 1-1-1 seems to be shown as gamma 2.2. So on mine for example, with everything calibrated and profiled for Rec.709/2.4, anything 1-1-1 will show as I expect, gamma 2.4. ![]() So whatever gamma is applied via monitor/LUT box will be used. In some applications/CM, 1-1-1 will show as Rec.709 without a gamma specification. And need to know, professionally, exactly what PrPro does with the NLC tags inbound and outbound. They work out of Resolve, Baselight, and Avid mainly, and have gear including $10,000 spectroradiometers to use for calibrating their spendy monitors. I work with some of the top colorists in the world daily. The "display color management" preferences option makes PrPro look at the monitor's ICC profile and attempt to remap the image to show as correct Rec.709 on that monitor's color management system. I know the app is hard-coded to assume Rec.709 b-cast standards for monitors: sRGB primaries, D65 white point, gamma 2.4, and 100 nits monitor brightness in a semi-darkened room. And there is no published information on what PrPro's NLC practices are concerning both reading and publishing tags (to file headers on export). Tags are rather crucial to working in video post professionally.
