4K restoration??? Does this mean Perfect Blue is going to get a 4K UHD BD release in the near future given this announcement. If it does, I'm not sure if Dolby Vision would improve anything on the visual and the wide color spectrum given that even in regular SDR, the film is still colorful no matter what.

Already released in Japan. Probably same 4K as that release but with subs added.

OK, I didn't know it came out in 4K UHD BD in Japan already. Uh, question: what kind of HDR does the JPN 4K UHD BD used, Dolby Vision, or HDR10? The CR article didn't say what HDR the 4K BD used, and even blu-ray.com's entry on that release couldn't give any info on it too. I would like to know if it used any HDR or no HDR at all.

This was my first Satoshi Kon film and still my favorite and I'm glad to see it coming back to theaters with a new remaster.

No HDR at all. Someone in the Blu-ray.com forums confirmed they bought the JP BD, but it was SDR. However, that doesn't necessarily mean GKIDS won't try to apply some light grading. Although, to be honest, most 4K HDR cel-animated titles I've personally seen tend to not benefit from HDR that much. And the ones that do get HDR grading, unfortunately, also seem to get DNR'd a lot, so I guess that's the tradeoff: color boost at the sacrifice of grain and detail or vice-versa.

Ah OK, thanks for the information and I will agree with you that HDR on cel-animated animation film don't bring out that much improvement. And about the one that do get HDR and it lead to them getting excessive DNR, that's the first time I've heard of that and I can see why HDR on cel-animation don't turn out well. Now I learned something new.

lol, I feel yah. I am… not good with horror. I do sometimes try to watch or read the classics, like Uzumki, but usually give up pretty quickly. Just taste enough to see why people love a thing, and then nope right out.

I wonder if that is due to cel animation being evenly lit. From my limited knowledge of HDR, I know it is a lot to do with high contrasts between colours and brightness. Cel animation(digipaint to some degree) is either bright or dark, not a mixture of the two in the same frame. So by nature it is extremely low dynamic range.

Yes. HDR is supposed to bring out colors/contrast/blacks, but more so in the sense of natural lighting that was captured on film. However, since a lot of cel-animated works have all that "lighting" baked into the source (literally colored into the frames, unless you start considering the era of digitally drawn stuff), there's not as much natural lighting to actually pull from, and the HDR just ends up accentuating some of the color and/or grain.

But making the grain look more pronounced can overdue the already filmic look, even more so on OLED displays, then possibly lead people to think "why is there so much fuzz on the picture?" Not to mention all that grain adds a crap ton of extra detail and information, hence, taking up more memory on the disc, which then leads to the company having to use a 100GB disc for the product instead of a 66GB one, thus increasing production costs.

But yeah, it's as you said, the dynamic range is low because there just isn't as much contrast in cel-animation versus something like live-action, which has all sorts of lighting elements to account for.

I've actually avoided buying the 4K for Akira (1988) after hearing about how much grain they took out. I even downloaded a pirated rip just to see the end result, didn't even make it past the opening motorcycle scene, deleted the file out of disgust, then just said I'll stick to my old Bandai BD with the supersonic 5.1 mix (which apparently wasn't even correctly ported over in the U.S. UHD).

Ghost in the Shell (1995) looks pretty great. But that's the only cel-animated title I've seen in 4K that actually retained a lot of the grain structure.

Anyway, concerning the Perfect Blue UHD in Japan, they supposedly didn't touch the grain at all and just cleaned up much as they could of everything else (dirt, print damage, stabilization, etc.). People who have seen that version say it looks fantastic. Whenever theater tickets go on sale here in the States, I'm pre-ordering, then scheduling that day off. And hopefully, GKIDS will release that on 4K disc/streaming over here as well.

Hey Tony K,

I got chance to read your post above about HDR being applied to older animation specifically cel animation and I appreciate your insight into that, and thank you for mentioning about the DNR being used in Akira, I didn't know they removed so much grain from the 4K UHD BD. Thank you for that info Tony.
