.05 - 1000 nits or .005 - 540 nits

reminder that people struggle to see ~10 nits too well in a well-lit room. that second bracket is a huge cop to display manufacturer's delusions.

also per-frame metadata is stupid and i'd be surprised if the dolby solution that ships actually uses it for anything

it's dynamic range, not brightness. the ability to do shadows is meant to also be improved (although in practise it's just not going to get worse)

also 10k nits looks sweet as and is a visible improvement on 4k

in theory 10-bit pq follows one of the barten curves for just-noticeable difference, so it sits right on the line where if you take code points away you start to see banding. in practise, dolby almost certainly can't get a 20k nit screen going.

that's exactly the case, but the dark regions can't afford to lose the ~50 points you'd need to reasonably cover 10,000 - 20,000 without visible banding.

10bpc had the advantage of existing infrastructure. prores is 10-bit, SDI is already all 10-bit and 10-bit HDMI came in just in time to be used. you can also pack 10-bit into a 32-bit integer. 12bpc is basically as many as you'd ever need though, and that's where all the intermediate formats will probably go.

is that necessarily the case? i mean, i have to imagine, that while no doubt lambasted as a complete waste in *this* thread, hdr will eventually end up rolling out on stuff like cheap youtube shows which have enough post-production done that they can quickly tweak it into sanity (e.g. clamp it out of any scene where it'd otherwise look too terrible, leave it in when it makes content a bit more lively), but i guess dolby vision is really just for stuff where you have many expensive pro post-production hours to spend then?

the two major things dolby vision gets you over HDR10 are support for using the full 0-10,000 nit range of PQ in 12-bit, which isn't going to be visible on a regular desk for a few years yet (and when it does, someone will be waiting with a free standard for it) and calibrated output, which is pretty much the definition of 'too much effort'

yeeah it's 48fps so they could half it and mush it up a little bit for the 24fps version, which sucks. 120fps would have been better but billy lynn was pushing the boundaries out even for today. still mad i didn't get to see the preview showing of a scene in 120fps/HDR/3D

right but there's no point to that, the 24 fps release i mean. all the digital projection systems already in place could at least handle 30 fps display, film distribution was nearly entirely dead, etc.

there's a lot of grody film types in hollywood who are convinced 24fps is a totally unique, magic frame rate. they're generally people who are pretty unhappy with the advent of digital capture/distribution full stop.

oh yeah that's a nice arri 24mm prime you've got there, allow me to place your �15k glass right here in front of this lovely loving three-way prism. optical aberrations? what the gently caress are those?

and let's hope you never loving drop this thing because if those sensors move half a millimetre out of sync you're going back to the clean room

which you need to fix your camera because there's a stupid loving block of glass in there

all because idiot nerds understand pixel count but not colour science

duuuh, my screen has a red green and blue for every pixel, so should my camera, even though the colour channels correlation 90% of the time and interpolation is perceptually indistinguishable from capture, i think we should have a full loving image sensor for blue pixels

polarisation???? who knows

yes, I know that bayer patterns are a thing we have to live with and that they’re fine Most of the Time.

but it seems that somebody would’ve put something like a foveon sensor in a digital cinema camera by now and at least tried to market it to VFX studios or whoever based on the increased color resolution, though.

the thing is, demosaicing algorithms are really good. aside from aliasing, you get pretty much everything you need and the operations which make it better from there (various blurs, sharpens, other filters) are a known quantity. the foveon design has all its own set of issues (as well as a few in common with the bayer pattern) and there aren't as well developed solutions to them. those 5 microns of depth might suddenly be more of an issue on a 35mm equivalent sensor with an f/0.9 lens.
