It’s because the v1.0 DNR version is basically an entirely different “fork” from the v1.0 No-DNR version with an entirely different base color grading, so any color corrections which are done to one of them can’t be applied to the other.
If Williarob pops in here, he can explain better than I, since he’s the one who did v1.0 DNR in the first place.
There is a new version in the works which uses DrDre’s new reel-by-reel color grading that should finally give us a new DNR version and bring DNR and no-DNR into parity so future updates to one can be applied to the other, like 4K83.
Thanks ChainsawAsh thats the kind of info I was looking for, good to hear a color grade DNR is a future posability still as I find the DNR is done perfectly in ANH Tattoines sandy landscapes were far too grainy 😄 with non-DNR.
So DrDre’s color grading technique is the way forward it sounds like, look forward to seeing it at some point.
