DVD came out in 1997. Yes if the trend holds, around every 10 years a new and improved optical disc format is released. However by 2026 10Gbps Internet speed or higher should be common, which means the studios might have 8K download or streaming movies with lossless audio instead of using optical discs.

8K will be here before 2026, IMO

And hi-def streaming will use a compression algorithm without loss of picture quality, similar to what MQA is for audio. And, there will be wars, conflicts, screams from some video communities...it is simply inevitable, it comes with the evolution of the cinema territory...@ home and abroad on the cinema theater's screens.

This is my opinion, no need to adjust the vertical hold on your tube.

Laser is the future, in projectors as in defensive protection of our solar system.

Really need much bigger screen sizes before 8k will be worth it for home use.

8K streaming I can definitely envisage (although "lossless" video compression is pie in the sky stuff IMO) but 8K optical disc? Noooooooooooope. The problem as I see it is that current BD structures and data rates won't be able to support high-quality 8K video, even with a next-next-gen compression codec, so it will need a new storage system and no-one's putting money into that kind of R&D for physical consumer media any more. It took mucho wrangling to get BD uprated to triple-layer capacity for large scale UHD replication, to say nothing of an entirely new optical format being developed from the ground up.

For long term archival storage then yes, top men will always be working on such things but the more data you cram onto these discs the more fragile they become which is precisely why they're being optioned for long term usage inside caddies, rather than being naked in the grubby hands of the average joe. Even in the archiving world those discs e.g. Sony's ODA are still far more expensive and far less capacious than LTO tape. Sure, the ODA capacities are increasing with each generation but LTO is increasing by the same metric.

"The result was the DVD specification Version 1.0, announced in 1995 and finalized in September 1996.
The world’s first DVD player was the Toshiba SD-3000, launched in November 1996.
The first DVD players and discs were made available in November 1996 in Japan."

10Gbps Internet won't be common in 2026.
As an example here in Germany, 75% of all households have Coax Internet available while less than 1% got optical fiber. With the introduction of DOCSIS 3.1 this year - which will have a high adoption rate by 2026 - 1 Gbps Download and 100 Mbps Upload is possible via Coax (Upload can be pushed to 300 Mbps if they increase the upload spectrum which is expensive). Other countries have a similar fate, only optical fiber allows 10Gbps speeds, which is basically nowhere to be found.

We'll see but I personally don't think so.
Today most movies are filmed in 6k-8k and mastered in 4k (special effects 2k-4k). Only the best movies/series are filmed in 8k and mastered in 6k (e.g. House of Cards).

In order for 8k commercial videos to make sense you'd have to film in 10k and master in 8k (special effects 4k-6k). I don't see this happening before 2026, especially not widespread.

Not only because of the filming/mastering aspect but also because of the diminishing visual returns after 4k (especially if the bitrate is too low), I just don't see 8k streaming happening.
My guess for 8k Blu-rays is 120GB Triple Layer Discs and Encoding via JVET second generation codec.

I never thought 4K streaming would become as big as it has done and yet here we are. But, as I said to someone else recently, I didn't say that 8K streaming would be any good - and yet since when did that put people off? It may well end up as the main delivery system for such content outside of Japan which will naturally have 8K TV broadcasts whilst we're still struggling to get 4KTV off the ground in any meaningful way. 'Twas ever thus, they had HD content on Muse LD while I was still in short trousers.

You're not usually watching a tablet or phone from 10ft away though...

No, from roughly twelve inches away.

No tablet but Samsung S7 edge, but don't want to watch on such 1440 x 2560. At my age (68) and far sighted I heed glasses to watch close, and prefer to watch on my LG OLED65E6.


Most experts will tell you that you need to be closer than 5 ft (I usually watch at 10) in order to see full detail of 4k contant at this distance. I would like a screen size that fully can feel like a Movie Theater at 10 ft. For such maybe 8k would be good, but many feel that exceeds current Movie standards.

Oh, you are a young man, in the same age bracket as me.

Say we have an 8K front laser projector, or a huge OLED 8K TV, with a screen's diagonal of 220 inches, assuming we are wealthy and have a large home theater room in our mansion.
We would sit, say, @ twelve feet from that screen...what do you think we would say?

For regular bank accounts, the 8K screen is 96" in diagonal (OLED or QLED or LED ... or front projector...real 8K), and we sit six feet from it; would 8K Blu-ray movies or 8K video streaming or 8K own photographed pictures and videos help?

As an aside, with regards to color, Panasonic has already manufactured a 55 inch 120Hz/8K/4K monitor using a backlight system with laser light sources which covers 99% of BT.2020

On a great screen that size and with some sort of good 8k source we would say WOW. Not that I trust some of these graphs showing screen size vs resolution, but they claim over 120" at 6'. So 220" sounds right. I suspect 100" might really be good.

If I can get a 8K 80" Sony FALD or LG OLED for $5000, fine, until then, let me sleep.

[DJR662]

As long as glasses free 3D will be "the next big thing" that comes along with it, I'm all for it.

When they get up to > 100 inches, looking forward to a reassessment by Steve Yedlin regarding his previous resolution assertions

I’m informed that apparently a big theme of InterBee2017 is 8K, e.g. at NHK:SHC booth and truck –
