8K is only gonna be for upscaling 4K UHD discs in the mainstream hollywood content sphere. I would be super shocked if 8K ever even became a thing in streaming for movies with scans 8K and above. Even 10 years down the line, that would be such a niche library it wouldn't really be a thing at that point.

I did hear that the movie "Seven" with Brad Pitt was currently under going an 8k remaster. A friend of mine purchased a Panasonic Ub820 from someone in Los Angeles recently (they got to talking cause it turned out they lived on the same block in New York before he moved to LA).. The guy is in part of the process on the remaster. I would not expect this to be common though.

Hey I'm all about scans and restoration work being done at high resolutions. As it only gives them better results when scaling to 4K UHD.

... and future proof in case somehow technology becomes so low-cost (the AI revolution theorizes such scenarios) that 8K and 4K content can be delivered lossless along side one another in the market for pennies, sent to your home in amazon drones as "physical" (not optical disc, but next generation hard drives etc) media.

In that dream world we'd want all our current stuff to be mastered at 6K or 8K so it can plug and play into the system with no wait times at all on that delivery for our wall screens of MicroLED 8K modules with no "seams" issue.

Not surprised if true, as David Fincher has been pushing these boundaries with his movies for a while now, working in a 6K DI on Gone Girl to deliver a 5K master for example.

IMO, all movies shot in 35mm/4-perf or better with the OCN preserved should be scanned and restored in 6/8K since there are still some benefits in term of details with a higher scan than 4K. It would be the ultimate restoration for a movie and avoid studios to scan and restore the OCN again in 5 years in 8K. Btw we all know that 8K resolution is the end of the guideline (UHD Phase-2) and will be the final public resolution for decades.

Most movies today are still finished in 2k for cinemas, but we "need" 8k scans for home video? Meh.

Granted I said much the same thing about 4k, but HDR is the real difference there. There's no "HDR 2" on the horizon, as far as I know. They might bundle 8k with glasses-free 3D I guess, but do we really think another physical format will come along? I guess anything's possible, but I doubt it. Also I've read several articles that said 8k screens with glasses-free 3D in 65" type sizes at a reasonable price is a pipe dream.

I was talking only about 35mm film with OCN preserved, not recent digital productions finished in a 2K DCP.
But yeah, i agree that even a 2K DCP in a home theater is good enough for immersion.

Samsung says their new Exynos chip which will no doubt power their next Galaxy flagship can record 8k 10 bit HEVC.

Many 4K transfers ARE done at 6K/8K at point of capture, e.g. the Arriscan on double flash mode (6K) or the Northlight 2 (8K), while others like the Scanity scan @ 4K across but use a method called Time Delay Integration to build up the image in lickle slices and claim an "8K equivalent" rendition of details. So we're getting the benefits of that oversampling in the final 4K product and have done for a while, even if the image wasn't ultimately output to a raw 6K/8K state (which is a lot of data to wrangle) and then archived.

Taiwan Display International 2018 is held during August 29-31 at Nangang Exhibition. Innolux 100 inch 16Kx8K S-UHD Display module exhibits the best for human vision ever. The product is equipped with the latest video chip, high-transmittance pixel design, high brightness, 16Kx8K high resolution (15360x8640), wide viewing angle and wide color gamut, to present images with sharper outline and stereoscopic feeling. No pixel dot would be detected at even as close as 50 cm. The combination of 16K and 100 inch panel enhance the image realism.

They might bundle 8k with glasses-free 3D I guess, but do we really think another physical format will come along? I guess anything's possible, but I doubt it. Also I've read several articles that said 8k screens with glasses-free 3D in 65" type sizes at a reasonable price is a pipe dream.

"Stream TV Networks, developer of Ultra-D optical/rendering technology that enables a video panel to deliver 3D images without viewers having to wear 3D glasses, is not giving up on 3D TV, even though major TV makers have largely abandoned the concept.

At last week’s CES 2019 in Las Vegas, the Philadelphia-based company demonstrated its second glasses-free 3D screen — a 27-inch “8K Lite” PC monitor offering 16 million pixels that sits between a 4K monitor with 8 million pixels and a full 8K monitor with 32 million pixels.

In November, Stream TV partnered with BOE Technology Group Co., the world's largest panel manufacturer, and introduced a 65-inch “8K Lite” TV.

"What the 65-inch television does for entertainment, the 27-inch Glasses-Free 3D monitor does for gaming — provide an experience of unprecedented quality and depth,” said CEO Mathu Rajan. “Since our technology allows consumers to view all existing content in stunning 3D, there's no waiting for dedicated content. As new higher-resolution content becomes available from any source, it only enhances the amazing 3D effect consumers and gamers see on our screens."

Both TVs use advanced optics and powerful rendering algorithms to create a 140-degree viewing angle and convert content from any 2D or 3D source for glasses-free 3D viewing, according to Stream TV.
These products are not yet available on the consumer market but the company hopes to have a brand partner this year with roll out in late 2019 or early 2020."

How does glasses-free even work? Is it limited to one viewer at a time?

Download 8K/HDR Video From Space!

Need something to watch on that new 8K TV? (You have one of those, of course, don’t you?) Florian Friedrich, a developer who creates HDR mastering software and who has worked with video expert Joe Kane to develop UHDTV test content, has created a reformatted 8K version of the 8K footage NASA recently made available for download on its website.

It apparently was necessary for Friedrich to reformat the original NASA 8K footage because it wouldn’t play on the Samsung 8K TV that he initially tried it with. Why not? According to Friedrich, “The whole encoding was not optimized for playback with CE-devices: wrong video levels, incompatible MPEG profile, critical bitrate.”

Friedrich’s consumer 8K TV-friendly version of NASA’s footage can be downloaded from his website here. All you’ll need to do to get it is enter a name and email address to receive a company newsletter.

The complete download package not only includes a reformatted 8K/HDR version of the NASA content, but additional 4K resolution versions Friedrich created with HDR10 high dynamic range, Hybrid Log Gamma (HLG) high dynamic range, and P3 wide color gamut, respectively. If nothing else, you can use these to check out the performance of your brand new 4K TV as this whole 8K thing gets sorted out.

Done! I LOVED that 4K HDR NASA video that LG did as demo content, so want moar pls

[gkolb]

Also Done! Wonder what the file size is for the 4K HDR, want to put it on a USB stick and feed thru the Oppo. My Sony Z doesn't like to recognize USB drives.

[Geoff D]

My OPPO had zero problems reading the 80-something GB file for 4K77, albeit from an HDD and not a USB Stick
