If I’m not mistaken, if the Bluray were GOUT synced, one could apply these colors easily, right?

No, it’s not a matter of being sync’d. The GOUT appears to have had a single color correction applied to it, which allows us to apply a single LUT to correct the whole film. For example, if the GOUT is 10 points too red, it is 10 points too red on every frame, therefore we can apply a universal correction to reduce the red by 10 points and the whole film will look better.

On the blu-ray, the colors are all over the place, so this sort of universal correction will only improve some of the shots, while making others look worse. While the whole blu-ray can be greatly improved with a single LUT (as JawsTDS proves here http://originaltrilogy.com/post/id/1042832, it would not be possible to match the colors of all the shots in a single pass).

No, I get that. What I’m saying is that I thought that Dr Dre was going to do a one pass LUT with the GOUT and THEN export a shot by shot LUT. With this shot by shot LUT, you can take any GOUT synced video file and have it come out like the technicolor.

Yes, that would certainly be possible, but you would also have to contend with many of the color issues (missing gradients, and is some cases missing colors), that NeverarGreat has tackled for his bluray regrade.

Right, gotcha. So your shot by shot LUT would work best on neutral scans so to speak?
