Screenshot Comparisons 4K

[Streetlight]

Can someone post screenshots comparison between Silence of the Lamb 4K vs Criterion BD?

[Dino1482]

I'm very curious to see screenshot comparisons between Disney+ 4K and the disc counterparts

I just watched Cliffhanger on my IPhone XS and didn’t notice any bright highlights. Is there something wrong with my phone? I’ve been disappointed with bright highlights in general on it. I would think if something is 1200 nits it should be noticeable.

I hope you're joking.

Don't judge a transfer by a phone or tablet and don't expect a smart device to have the capabilities of a large TV display.

I can't imagine watching a movie on a phone anyway. The experience is poor and your eye muscles will be hurt.

David Lynch and myself would certainly think so.

This is especially prevalent with animated films. Trolls is a great example.

It doesn't help that a lot of shop demos try and sell UHD in this fashion either with ultra saturated bright videos with the sharpness turned up to extremes.

I'm amazed no screenshot comparisons between the 4k restoration of the Twin Peaks pilot and the 1080p version on the Entire Mystery set has appeared online yet. Anyone?

[Streetlight]

I need comparison between:
Dredd: US BD vs FR BD vs Scandi BD vs US 4K BD and/or DE 4K BD. No spoilers.
Batman Begins: VC-1 BD vs AVC BD vs US 4K BD. Bonus if it includes the 100GB 4K BDs
Oblivion: 4K BD vs 4K Digital
Silence of the Lambs: Criterion BD vs 4K Digital
Batman (1989): Remastered BD vs 4K BD
Batman Returns: Remastered BD vs 4K BD
Taxi Driver: Mi4K BD vs 4K Digital
Gone Girl: BD vs 4K Digital
The Disaster Artist: BD vs 4K Digital

Hotel Artemis

A quickie where I was mostly taking a look at the HDR.

US IMO has the better pq (less filtered and there's some aliasing on the German one - didn't notice the latter when whatching the movie mind you), Germany has the HDR though, so YMMV.

#13 isn't the same frame - I only it included again, because it's the 2nd localized title on the German release...

US (SDR) | Germany @100 nits (I believe - it's been a while...)

1.

2. (#3 613 nits)

3. (#3 357 nits)

4. (#3 575 nits)

5. (#3 667 nits)

6. (#3 667 nits)

7. (#3 529 nits)

8. (#3 546 nits)

9. (#3 757 nits)

10.

12.

13.

Those are remarkably close for being two different grades in two different color spaces.

I only have the 4k stream no Criterion

Many sites like this one, DVD Beaver and Caps-a-holic posted screencaps of the Criterion BD. You only have to take screencaps that will match those.

I know, I prefer my own caps as I know how to take them and a few sites do get it wrong

If you have filmmakers who know what they want and colourists who have the skill to provide it for them then you could have the two grades looking so close as to be identical at first glance, e.g. https://forum.blu-ray.com/showpost.p...&postcount=527

I'm actually more surprised things aren't closer than they are in general. Going between Rec709 and 2020 is just a mathematical conversion. I can convert a screenshot from a regular BD to ST2084/2020 and viewing it in HDR will look more or less identical to viewing the original in SDR. Vice versa for any UHD shot that isn't overly bright and saturated. There is the issue of tonemapping, i.e. what to do with the values that don't fit in the space you're squeezing it into, but even that doesn't account for a lot of the differences seen. For example why does The Shining have a much cooler white point on UHD than the new BD?

Which cannot be said often enough. Mind you that I don't have the knowledge re. the math myself (i.e. it goes beyond me, even though I'm actually good at math) and I have to rely completely on what the tools do, but I do know that, for the most part, it is just simple math (problem, as you said, being mostly the bright stuff).

Or in other terms: rec.2020 vs. rec.709 is completely overrated colour wise. People don't know or ignore the fact that rec.709 is a big subset of rec.2020. And therefore, for the most part, can be converted without any substantial loss. Which is also the reason why the converted caps aren't as useless as some make them out to be. And I don’t say that only because I do them quite often. One "only" has to be careful re. the bright stuff (and therefore the dynamic range). Converted UHD caps often having way better colours than the BD counterpart says it all.

Because Warners' own SDR conversions are whack, yo. Just look at their new 1080p Blus of The Matrix and 2001 too, they've got markedly different colour to the HDR versions and not just becuz SDR, they're materially different grades/trim passes.

But yeah, to the other issue it's not that upconverting SDR into HDR is some kind of unicorn to get right, but it does still need competent people as maths isn't always everybody's cup of tea. And for the reverse then competence is essential in getting it right, although there is a certain amount of subjectivity introduced when it comes to handling the tone mapping side of it, which can drastically affect APL and colour.

With due deference to the king of caps Andreas, we do often see "better colours" in SDR conversion but the more that the colour is tied into brightness the more it can get leeched out when converted, especially with a rigid conversion like what capsaholic use rather than Andreas' nuanced 'multiple levels' approach, which is why I don't like to take the colour in converted caps solely at face value. Black levels, yes, I take them as seen, as nothing should be happening to the black floor with a sensible conversion, and DNR and sharpening are easy enough to detect though there's no substitute for seeing that stuff in motion, 'twas ever thus.

Maleficent

Way too many caps, but therefore much to choose from (maybe people also have some to kill these days...). Date says Nov 2nd 2019 btw. - I really did procrastinate uploading this one...

Anyway, IMO a very nice, yet subtle pq upgrade from Disney. I actually just peeked at Geoff's review () and yes (other than the removed flatness), I found the blacks to look markedly better here as well without being crushed. Good example was the scene from #22 forward IIRC (that goes also for Maleficent).

Don't have any additional comments, because it's too long ago.

BD (upscaled) | UHD-BD (madVR/SDR/200 nits)

Disclaimer as to why the UHD-BD images may appear to be too dim and please ignore any off-looking colours:

[Show spoiler]Please note that the UHD-BD shots have been converted from HDR to SDR using special techniques, which drastically compresses the dynamic range of the original image (the colour bit depth has been compressed as well). The UHD-BD shots are therefore not an accurate representation of the original HDR image - dynamic range, colours (tone and intensity) and contrast should be taken with a big pinch of salt and the main focus should be on comparing details. Typically, the image will appear too dark (which is by design when the caps are done at 200 nits; on its own they should be viewed with monitor brightness set to 200 nits), may lack a certain "pop" and may at times also appear "boosted" when compared to the BD shots. The SDR conversion should still give you a good idea of the actual image of the UHD-BD though and one should also be able to at least catch a glimpse of the increased dynamic range. The BD shots have been upscaled for comparison purposes, but other than that should be accurate.
