UHD BD to BD?

[Beber]

Here's what I obtain with Mission: impossible, which I just saw on 35mm last night, June 28th: the Blu-ray, overall, is quite faithfull. It's in the ballpark. I feel it needs to be warmer on the color temperature and probably a couple points towards the green side on the color spectrum to cut back a little on the red.

Blu-ray/RipBot (-5, 0.9, -1, 0.9)



Too pink on the Blu-ray. Not enough on the remaster.



Too pink on the Blu-ray. Not enough on the remaster.



Both in the same ballpark. Better looking on the remaster that cuts back on the pink skintone but still some on the cheeks. That's good.



Better contrast on the Blu-ray. A bit better colors on the remaster, especially on Cruise's leather jacket.



A scene that should look quite warm, so definitely better on the Blu-ray. Way too cool on the remaster, and the plant which Bluray.com enjoyed so much in here is nowhere as noticeable on 35mm. It's not supposed to stick out the way it does on the remaster.



A bit too warm on the Blu-ray, way too cool on the remaster.



Blu-ray here is dead on.



Blu-ray needs a bit more warmth or saturation for a better looking blue, but not to the point of the remaster which is way too colorfull.



The blu-ray is quite dead on here. The remaster makes the green drapes behind way too noticeable. This is actually one of the scenes I tested before testing my tweaking on the whole film, and thus why I reduced saturation to 0.9 instead of the usual 1.0.



Both in the same ballpark here, with a better looking warmth on the remaster...



... except that right after, when the Blu-ray remains consistent, the remaster is suddenly way too colorfull.



Blu-ray is a better match to the 35mm here.



Blu-ray is a better match to the 35mm here.



Blu-ray is a better match to the 35mm here, obviously. I don't even understand how the remaster can look that dark and weird...



... and even wierder here.



Blu-ray is way better here.



Blu-ray is a bit better here, but both fail in getting the city landscape in the backgroud right: it should be green. Definitely not blue.



Here, the door window is supposed to be mustard color, definitely not green. Blu-ray is better.



Blu-ray is dead on in its ability to give us the proper shade of cyan blue in the lensflares. The remaster is so wrong!



Blu-ray is dead on with that warm dusk lighting in this scene.






Blu-ray is dead on with that purple color on the umbrellas on both sides of the conversation.



Blu-ray is dead on with that orangy sunset.

Of course, my observations cannot take into account the way the actual HDR UHD Blu-ray looks, 'cause I don't have the equipment to see it that way. Nevertheless, I believe the Blu-ray colors, with a little tweaking, should be applied to the remaster using the color match thingy to give it a proper look.

I'm seeing a lot of people putting extensive work into getting the balance just right on these conversions.

I was wondering if anyone is intending to release any of their final versions or if this is going to be a strictly academic discussion with only settings posted.

I hate to be that guy, but I'm looking at the work involved (and my color blindness) and I'm thinking this isn't something I can really do on my own in any worthwhile way.

Well, for my part, my connection is so weak to upload stuff that it would take forever for a big file. So I just report back on my tweaking tests so that people can make their own versions if they like the result I obtain. And when I obtain nothing worthy, like on Mission: Impossible, I launch the idea for someone with the color matching know-how to put the Blu-ray colors onto the UHD remaster.

Beber did you compare with the french TV version with the french credits? Is it different from the Blu-ray?

The non-French parts seem to look the same:




But the French credit part does look even better in both definition and color (less pink) than the Blu-ray. Framing and aspect ratio geometry are also different, which indicates that the French part really is sourced from real 35mm French material:

Here's what I obtain with Mission: Impossible II. I haven't done the full movie conversion yet, just some tests on the first 15 minutes. The Blu-ray appears better defined, maybe as a result of edge enhancement, being an old master, but I don't really see the white thin line on the edges that usually indicates edge enhancement. The color timing is very different, obviously. Not as pink in the skin tone department, greener greys and a very warmer Seville, Spain sequence, with the love-at-first-sight flamenco. Framing is different, and the black bars thickness is also different. The movie will air tomorrow night in France, probably with a 35mm-sourced French opening credits, so that'll be the climbing sequence.

Blu-ray/RipBot264 (-1, 1, -1, 0.9):

[Colek]

I think RipBot264 is doing some weird stuff with quality of your encodes. This is how it looks raw from Remux, looks way superior to Bluray in terms of details.

[Beber]

Well, to be fair, I make my tests in 1 pass with the fastest rendering possible. That could explain it. Once the settings are determined, I do the full movie in 2 pass with much slower rendering.

I think the new HDR grades are almost being done on the fly in many ways. There seems to be much fluctuation even on a shot to shot baisis. I'm dying to see M:I 1's new transfer but don';t have any 4K gear. however judging by those it is technically great but all over the place in terms of color.

It must be remembered that the old master was literally reused time and time again and seems to date back all the way to the 1996 LD. I don't know if it is the same one used every time or merely a higher res one made in the DVD era but it is really outdated as were the ones for 2 and 3. I imported the Scandinavian discs with lossless audio and slightly better encoding.

Of course my question no one seems to be able to answer is if the thunderous original audio mix is on the UHD. Only the LD had it intact as every reissue mixed down the LFE and tamed channel separation.

I noticed during the 35mm screening that we could clearly hear Ethan feet touching the desk in the silent computer heist scene. They are quite muted on the current mix.
