I'll jump on this for the shift to HFR alone. Hopefully it becomes the standard sooner rather than later.

Haha, and I just got my new Oled-TV, no 4K support on it, but I'll buy a new TV in a couple of years either way.

i'm not sure about that, it's really confusing for people and I'm sure they won't buy an another Blu-ray player thinking they have already one ( PS4,Xbox One etc .. ), now I feel bad for all people that have bought a 4K TV that is useless now.

HDR 4K TV are over 5000$, good luck with that.

No 4k 3d support............ FUCK

Really?! Damn............. I guess we are still not there yet.

The Hobbit Trilogy 4k HFR in my veins!

To those afraid of having to upgrade their collection. I really think the visual upgrade for movies shots in 35mm (meaning 99% of movie in history!) won't be super noticeable, or at least way less than the one from dvd obviously.

I can be wrong but i'm really curious to see some comparison between a 2k bluray of a 35mm movie upscaled to 4k (on a tv or projector) and a real 4k master of the same 35mm movie.

35mm can be mastered at ~5k+.
An HD bd of T2 on a 60" tv will look worse than an UHD remaster of it on the same size.

there's really a lot more factors than that.

I have the dollars trilogy and all but one of the dirty harry movies, and at 1080p on 106" screen, there is blur from depth of field or focus issues. For some movies it simply doesn't matter how well it was restored, you can't fix issues like that.

So in my opinion older movies are going to be really hit or miss in 4k. Some, that don't have those types of issues are going to look stunning, others are just going to have super magnified flaws.
 
DTS:X and Dolby Atmos.

Are they here to stay and will I need to buy a new receiver? What kind of speaker configurations will I need to take advantage of these?

Lawrence of Arabia in 4K? I'll take two!


That's on the basis I purchase a nice 4K set. I'm willing, but it's hard to justify a purchase outside of gaming. Probably will not get a 4K player until the PS5 and next Xbox launch. Regardless, glad to see image quality be at the forefront for the new specifications, as it was sorely needed.

Yeah i always hear that but that doesn't mean anything. You can scan an analog source at infinity if you want .. Some will say the grain structure etc..

The real question is, are there details, on a 35mm film, and i mean visual details, like "i can now read that little thing in the background" that are missed on a 2k bluray ? I think not. I can be wrong.

Sure the pixel density will be better but it will be the same if the 2k source is upscaled nicely.

there's lots of receivers/processors that have atmos already, so they should be around for a while.

Dolby's website recommends 11.1 or 11.2 for atmos. It gets complicated because there's some speakers that are "atmos" enabled where they bounce the sound off the ceiling. Vs. having dedicated speakers in the ceiling.
 
Yes. This is good. I just hope the players aren't expensive. I mean BDXL drives are already around $70 USD.

If the price is right I'll try to jump in sooner rather than later.

I feel like there will be significant diminishing returns with most movies. This may be better for much newer stuff though.

Well that much is a given ofcourse, which is also why I mentioned T2, since it has a superb master.

Obviously it will look worse, but the question was how much worse. I'd be interested in that comparison also.

Well, 1080p will still look good, but the clarity of true UHD footage is just much more visually pleasing.

Well, infinity doesn't mean anything, that's why I said ~5k+, that's the point where you kinda reach "max" resolution.
And yes there are details, 35mm is a pretty great format.
 
Can we retcon old Blu-Rays to be called 2K Blu-Ray, just to fuck with cellphone marketers who are calling 1440p screens "2K"?

Oh, of course. It should be great for watching anything recent with really expensive action scenes on a large 4K TV though. Nature documentaries look pretty nice in 4K as well.

The reason i don't believe it, but maybe you can find an example to prove me wrong: I can't find a 35mm movie, in bluray, that has an image as sharp as a digitally shot movie in the same format. (i'm not talking 70mm obviously).

So for me that means something simple. 35mm film doesn't "max out" a 2k resolution in term of actual visual details. Now, maybe 35mm scanned at 4k or more can be sharper, i know there are some of them.

This will be years out, as despite being filmed in 5K, the final master was in 2K, with the special effects rendered in that res too.



I believe LOTR can only ever go up to 2.8K because of the way it was filmed.

Just in time for the LOTR remake then! (Please don't attack me with pitchforks, I was only joking)

Bought DVDs for 7-8 years; now I've been buying BRDs about that same length of time.

Each collection represents a few thousand dollars investment.

Have no problem spending another few thousand over the next 7-8 years on UHD BRDs. Considering how much enjoyment I get out of my movie collection, and how I'm able to give away my old disks to friends when I replace them.. It's not even that expensive of a hobby.
 
What happens if you put a UHD Blu-ray in a Blu-ray player? PS4?

If Sony and Microsoft can upgrade their Blu-ray playback to partially support the UHD spec (4K, no HDR, or HDR, no 4K, etc.), this has a chance to take off.

Are the formats modular, like Dolby Digital Plus, where if Plus isn't supported, you still get Dolby Digital sound?

I didn'tsay as sharp, since that would be weird, but it's definitely of a higher grade an HD scan of the print.

this is going to be a niche product, blu ray already is, most people just stream nowadays. it's only cinematophiles that seem to but physical media these days.

Shouldn't Ultra HD really be called 2k, seeing as full HD is defined by its vertical resolution i.e 1920x1080.
4k standard is 3840x2160 so surely it makes more sense for it to be called 2k??

4K is a bigger number.

Bigger = better for marketing purposes.

Sharpness has more to do with the lens than the medium on to which the image is captured. Also perceived sharpness does not necessarily increase with an increase in resolution.

Our eyes are most sensitive to high contrast, "coarse, contour-defining details in an image" rather than lower contrast very high frequency details. So a relatively low resolution image with many high contrast coarse details will appear appreciably sharper than a higher resolution image without as many. The quote is from the .pdf I linked to below.

A real world example would be Technicolor film prints.

Technicolor prints were made using lithography as opposed to regular prints which are produced photographically. They have lower resolution to a regular print, but due to how they are made have much better contrast. This makes them look much sharper, when projected, despite their deficiency in absolute resolution.

A good visual example of this sharpness/resolution relationship, and details from 2k and 4k scans, can be found, along with more information on this than you could ever want or need, in the following .pdf.

http://archiv.arri.de/infodown/cam/broch/2008%2003-25a%204K+%20Technology%20Brochure.pdf

So just because digitally shot movies tend to look "sharper" it doesn't necessarily follow that they are actually higher resolution. If I had to hazard a guess I'd put it down to the fact that sharpness and density of information is part of the aesthetic of many modern films. That is true whether they were shot on film or on digital cameras. Sharpness can be easily cranked up during a digital intermediate, if desired, irrespective of the source.

I have little doubt that many (most?) 35mm sourced films can look appreciably better in 4k than on Blu-ray. But, as noted by others, the difference may not be as dramatic as the jump from DVD to Blu-ray.

This is because the sorts of details which 4k would excel at reproducing are the high frequency, relatively low contrast details of the type mentioned above. The really important (from a perceived sharpness perspective) coarse, high contrast details can be adequately reproduced on Blu-ray.

As for 8k, there is next to no content available at 4k. Most films from the last 10-15 years are stuck at 2k (or 1080p in video terms). So what would we watch on these 8k sets?

4k standard is 4096x, not 3840x (uhd)
2k standard is 2048x, not 1920x (hd).

Surely a compatible odd will make it to a future PS4 revision.

Can we expect wider gamut, HDR and HFR to trickle down to streaming services in the near future? Is the bandwidth cost heavy?
