Has there been any more info on HDR for the Planet Earth 2 UHD? I've read that it's only available to specific Panasonic TVs. This is a deal breaker for me if true.

Wow, talk about Chinese whispers.

The BBC's iplayer streaming trial for HDR (which included a short clip from Planet Earth 2) is HLG format, because HLG is what will be used for broadcasting HDR. At the moment, only some Panasonic TVs can view HLG with firmware upgrades for Samsung's 2016 range already announced and no doubt others to follow.

That trial is nothing to do with the UHD Blu-Ray release of Planet Earth 2 which will be a fully standards-compliant (ie HDR10) disc.

Has anyone here watched the new 4K Blu-ray of Donnie Darko which was released by Arrow Video this past December in the UK? It is not a UHD release - just a 4K blu-ray.
Thanks!

So it's one of those "mastered at 4k" releases for standard Blu-Ray? It's 1080p then. Blade Runner was mastered with an 8k scan of the film negative but it's still a 1080p release.

Yes, it's this: https://www.amazon.co.uk/Donnie-Dark.../dp/B01LW6R5H7
so off-topic for this thread.

However, it did get a full 4K remaster:

I have successfully downloaded some HDR videos from YouTube onto my PC, but the file extension is webm. This will play on the PC with sufficient HW capability and proper software, but does anyone know of a way to extract or convert these webm HDR files to a container (.mkv, .mp4, etc.) that can be played on my LG OLED? Is it possible to play these .webm files on Sony Android TV platform with VLC or some other app? Has anyone tried?

Then you take a movie like this which is already ultra sharp and upscale it with your TV and there really isn't that much room for improvement here besides HDR.
PS: I am using the Netflix app on my TV and upscaling to 4K, maybe you are upscaling through another device, causing it to be not as good? I remember, my K8500 was a big quality downgrade when it came to upscaling BDs compared to my TV.
Thanks for clarifying that. When I saw aaronwt’s post asking if he and I had seen the same show, Spectral it seemed clear to me that he had misunderstood what I was saying. I agree that UHD HDR, at least all of it I have seen, is easily superior to 1080p HD. But 2160 UHD without HDR is often virtually indistinguishable from 1080p HD.

I do not have the HW capability on my PC to play the files smoothly, and I do not have a 4k video card. Apparently MPV auto-detects HDR material in a .webm container.

mpv
a free, open source, and cross-platform media player
https://mpv.io/

see:

The Sorry State of Youtube HDR Video
http://www.personal-view.com/talks/d...e-hdr-video/p1


It seems that someone came up with a command line in ffmpeg to successfully convert downloaded VP9 P2 HDR streams from YouTube to HEVC, which should in theory be able to be played via USB with the internal media player in most UHD TV's.

VP9 to HEVC hdr demo conversion?
http://ffmpeg-users.933282.n4.nabble...td4678255.html

Perhaps someone would like to try themselves and report on their results. I know many who do not have 2016 Samsungs or Chromecast Ultras would like to download/play YouTube HDR content on our displays.

Thats because you have a Sony tv, which in my opinion has the best 4k upscaling available. So for you, the difference will be very minor but for others, the difference is more noticeable.

But that assumes the HDR material is in the webm container. The stream you have saved is probably plain VP9 with no HDR in sight.

I did not realise you had multi-posted the exact same question to different threads

How can you be sure the stream you have saved is HDR? I bet it isn't, unfortunately. After a negotiation where it determines you haven't got VP9 profile 2 capability, YouTube will serve the down-converted-to-SDR VP9 version to a PC and not the HDR VP9.2 version.

(If it is - great!).

When I had a Sony 4k,I used to say that too. That there were no difference between 1080p and 4k. Probably because of the Sony scaller.

Now on OLED, I see the difference between the two more easily.

I've noticed on every 4k display I've owned the difference in video between 1080p and 2160p SDR. I have Samsung, LG OLED and Vizio. I've never owned a Sony 4k TV though. I got turned off by Sony when I found out their Ultra app only works on specific Sony 4k TVs so I don't think I'll ever purchase one.

I just uploaded the world's most boring HDR demo clip:



It plays in UHD HDR on the Chromecast Ultra.



It is a collection of stuff we shot for 8K resolution testing, but I decided to grade them for HDR UHD.



More info:



This is a HDR video test clip, it is a handful of single frames shot on a RED Weapon 8K Vista Vision camera. The frames were exported as 8K 16x9 16bit TIFFs from REDCINEX beta using IPP2. The TIFFs were then graded for HDR in Davinci Resolve @1000 nits and exported as UHD/HDR.

I cannot accept that from eight feet I would see more detail in a UHD image on a 65 inch TV, OLED or not, than I see on my Sony 940D from the same distance. Obviously, though, you are entitled to believe whatever you want to believe.

In the interest of full disclosure, I carefully considered a 65 inch LG OLED but my research convinced me that for the same money, the highly regarded 75 inch Sony LCD FALD was a better bet. The silver lining here is that we are both happy with our UHD HDR TVs. Enjoy yours in good health.

What we see on any TV is a matter of screen size, seating distance, and individual visual acuity. With that many variables, anybody saying "My TV has better image quality than yours!" is silly. What next, "My old man can whip your old man?"

Could be. Or it could be evidence of my aging eyeballs. I would be the last to challenge that hypothesis.

True, but you can tell the difference between 1080p and 2160p SDR from any size TV by just getting closer to it if it is a smaller size. What I'm saying is that no one should say there is no difference at all because that's just not true.

I said that I couldn't see any difference between the 1880p and UHD only versions. Subjectively, I can't tell much difference. UHD and HDR are another matter, of course. I see that difference clearly.

In the interest of full disclosure, I carefully considered a 65 inch LG OLED but my research convinced me that for the same money, the highly regarded 75 inch Sony LCD FALD was a better bet. The silver lining here is that we are both happy with our UHD HDR TVs. Enjoy yours in good health.
Maybe that is the issue, the distance? I sit between 4 feet and 6 feet from my Sony UHD TV. So it's easy to see the difference between the resolutions and between HD and UHD streaming and HD and UHD disc.

Yes distance and screen size are the two factors that are important in being able to see the difference. For 65" 4K, most people would need to sit about 4.4 ft to see the full detail of the 4K screen, but will see some difference between 5-8 ft. Beyond 8ft, most people stop being able to tell the difference at this screen size.

And don't forget the viewer's visual acuity. At my age, I think about that more all the time. My corrected vision is still 20/20 but, as my ophthalmologist reminds me, it's not "normal."

I broke a rule I had made for myself when I ordered the UHD HDR disk of The Arrival. Ordinarily I won't buy a UHD HDR disk unless it has Atmos audio too. The Arrival disk is "only" DTS-HD MA 7.1 but I bought it anyway because of how highly regarded the film seems to be. Also Amazon is selling it at a bigger than ordinary discount.

I didn't think the video quality was anything to call home about but thought the movie was better than others have posted on this thread. Let us know what you think after watching. I only have the Vudu digital UHD copy so I don't know if the disc is any better?

How can you be sure the stream you have saved is HDR? I bet it isn't, unfortunately. After a negotiation where it determines you haven't got VP9 profile 2 capability, YouTube will serve the down-converted-to-SDR VP9 version to a PC and not the HDR VP9.2 version.

(If it is - great!).
I fully admit that I am not very savvy when it comes to all of this, which is why I thought others who are more experienced/knowledgeable might like to give it a go and confirm that yes, I am downloading HDR files from YT onto my PC.

The files I am downloading from YouTube (which are labeled HDR only viewable on Chromecast) when I play them in MPC-HC and check the properties indeed say VP9 profile 2 yuv420p10le.

Why doesn't someone here like yourself try it for free for themselves to confirm?

youtube-dl Download videos from YouTube (and more sites)
https://rg3.github.io/youtube-dl/

It seems the command line -f 337 specifies to YouTube to send the HDR version. It looks like you did not actually read through any of the links in my prior post.

You don't have to wait: You can already both download and stream/play the Youtube HDR files using free software:

Download:

youtube-dl -f 337 'htt ps://youtu.be/9WRW3f8ZGWQ'

Play directly from stream:

mpv -vf format=colormatrix=bt.2020-clrimaries=bt.2020:gamma=st2084 -vo opengl-hq --ytdl-format=337 'htt ps://youtu.be/9WRW3f8ZGWQ'

(I inserted a space in "https" to avoid the forum software to display a player instead of the URL.)

As you can see, the only difficulty left is that players like mpv (using ffmpeg for decoding VP9) are unable to recognize the VP9.2 flags that indicate the EOTF and colorspace, but you can specify them manually as displayed above.

Sorry I wasn't have a go - just wanted it to be a little clearer because the marketing "remastered in 4K [but it's a normal Blu-Ray]" stuff was deliberately designed to confuse (con?) consumers
