Pixar's Render Farm

it's almost certainly rendered in cinema 4k (4,096 x 2,160 pixels), if not more. moreover it'll be in a 16/32bit log colourspace as well

Nobody renders higher than 4k DCI unless the film is screening on large format (imax etc).

The color space will be acesCG most likely these days.

ahh smashing, I've been away for a while. I had heard rumours that they'd made a new colour standard, but I'd not actually looked into it.

Have you examined it or are you guessing? Because I'd have assumed they did too but I see jagged stairsteps on the 4k stream when zooming on sharp edges.

There is no way on earth that they will render at 1080. If it was 2007 it might have been 2k.

The master will have been rendered into a DCP.

What gets delivered to the streaming service is another thing.

what then ends up at your screen is even more of a guess.

A 4K dcp is a JPEG2000 stream[1], with 16bit colour. Something like 60-120 megabytes a second. Obviously this isn't practical to stream to consumers. 4K over a stream is always a balancing act, more often than not it drops to 1080.

[1] well normally it is

But you shouldn't be judging a stream, it's the worst version.
