Holeeeeeeeeey shit - a CG animated movie with a 4K finish?!? Has the dam broken at last?

No 3D helps, pretty sure it is all IMAX 2D in the states and UK, but there are 3D 4DX screenings.

Well, that doesn’t make any sense. If there are 3D screenings, there’s a 3D DCP that had to be rendered. It doesn’t matter if it went to one screen or 4,000- it still took just as many machine-hours to render, thus providing the very same impediment to also making a 4K DCP as with any other CG movie.

I thought encoding of 3D content to DCP was still relegated to 2K resolution.

It is. The (2K) 3D DCP and the 4K DCP are separate packages.

I bet the 4k DI is a 2k upconvert. Doesn't take as long, especially if they also rendered a 3D version.


If Disney/PIXAR stopped with the 3D releases, they could do true 4k renders.

I'd assume both the Dolby Cinema and IMAX-laser 'DCP's are also 4K.

Less means its worth a 4k finish as 2k shows are not the majority and the 4DX would be a seprate file anyway.

Of course it's got 3D. You guys do know that the release info is available to view, right? The DCP for the USA is a 400-ish GB file that contains 4K 2D and 3D 2K files, along with 5.1/7.1/Atmos audio options.

See above: DCPs contain completely separate 2D and 3D encodes so they they can be done at different resolutions, this is nothing like BD's MVC encoding for 3D which piggybacks the 3D layer atop the 2D.

Upscaling for theatrical DCPs make no sense whatsoever. I mean, IMAX does it for their stuff but as its IMAX then who knows what other special sauce is in there, but for a regular projection in a regular cinema there is no benefit to doing so. No improved range or gamut or colour space or compression vs a 2K DCP. And if it's being projected at 2K then it will literally throw away 75% of the '4K' image anyway.

So I'm thinking that this might've been rendered at 2K+ but not all the way at 4K, that way you still get some resolution benefits.

There’s the anti-aliasing benefit, especially on larger screens, which I’m sure is why IMAX does it.

The only times I've ever seen aliasing in a 2K DCP were entirely source related, like the wibbling on Spidey's suit while he's sitting on the fire escape in Homecoming. Which, incidentally, is still there on the 4K upscaled UHD. And if such a benefit is there then why haven't more studios done so? IMAX do it becuz IMAX, it may have someone to do with their special sauce overlapped dual projection tech, but I cannot recall any prior instances of an upscaled 'regular' 2D DCP.

Well, I can’t speak to how much practical value it has, but that’s certainly what it’s about- it’s the primary point of upscaling.

Besides, you’re just talking about visible artifacts. You may not be conscious of it, but on a larger screen, a more smoothly-stepped curve can make a difference.

[Geoff D]

I'm as nitpicky an SOB as you can get, but if I can't see x problem then I'm happy enough with that! I just feel that if this was some sort of proper problem, even sub-consciously, then shirley it wouldn't have taken almost 20 years before the first 2K upscaled regular DCP made an appearance?

Still, perhaps I'm guilty of overthinking it. Maybe it was finished at regular 2K but uprezzed entirely at source for the reasons you describe, because of this being CG animated and not live action (where such problems are harder to discern IMO).

[Doctorossi]

Yeah, it’s not really about solving problems; it’s just the same subtle improved look our 1080p Blu-rays exhibit when we watch them on our native 4K screens.

Yes but the actual source you're playing is still 1080p, it's being upscaled at the display end which is the same function that a 4K projector would do if playing a 2K DCP...so there's no need to upscale it at source level, it's the display level where the pixel density matters most in this situation.

If anything the biggest benefit to having a 4K projection - regardless of a 2K or 4K DCP - is the lack of visible pixels, which is why IMAX do that whole 'dual overlapping projectors' thing so they can get away with blowing up their 2K Xenon digital projectors to gigantinormous sizes. (That the BFI IMAX, the biggest screen in Britain, still doesn't have a Laser install kinds boggles my mind.)

Even on a non-huge screen the 4K projection makes a huge difference, at my local indie theatre I could see the pixels from the first few rows but they switched to a 4K Sony PJ a while back and the pixels, they gone son!! But, again, you don't need to have the upscaling baked in at the source level to achieve this in the 4K theatrical environment.
