Ghost Towns Is the First 8K Video Posted To YouTube -- But Can You Watch It?
Iddo Genuth writes: 4K videos and movies are still far from common and now 8K seems to start making its appearance online. A few days ago, what might be the first 8K video entitled "Ghost Towns" was published on Youtube and you can now watch it for yourself in its full 7680 × 4320 pixel glory — that is if you happen to have access to a 8K display (or projector).
The video was created by cinematographer Luke Neumann who used a 6K EPIC DRAGON camera using some advanced and complex techniques such as shooting in portrait orientation and then stitched the video together in Adobe After Effects. Some shots simply scaled up by 125% from 6.1K to meet the 7.6K standard and handheld stuff was 6K scaled up by 125% and sharpened up.
Youtube is now offering an 8K option and according to Google: "8K video has been supported since 2010, but that labeling for 8K video (the 4320p/8K quality setting like pictured above) was added "earlier this year — but presumably there was noting to view — until now...

It's worth noting that this video is only 8k resolution, but it's not what the eventual 8k broadcast standard will be. That requires a higher frame rate and higher colour depth as well. Same with 4k, it's more than just a resolution bump and most cheap 4k equipment is only HD with more resolution.

I was always wondering why a 4k video playing on a 1080p looks so awesome compared to same 1080P video. Well, the 4K and 1080P uses 4 pixels in a square with the same chroma. When you downsample the 4k on a 1080p, it goes to a 1/1 pixel matching, so no more 4 square pixels. You get a more detailed video with more vibrant colors and detail. Its crazy how better it looks. So the true visual quality is lost in the encoding on 1080p!
We are being robbed of visual quality, so more pixels is a selling point. (mostly)

And if you want to see the actual video, then here's the URL:

You can watch it while the linked article _about it_ times out after 30 seconds or so of trying to load.
It is dangerous to be right when the government is wrong.

Not only that, but the majority of the content is upscaled from 6K (whether using upscaling or stitching). It's cool and all that he spent the time and effort to do this, but, in my opinion, it's not true 8K until it's native video. Red has a 6K camera that can be upgraded with an 8K sensor.
But I'm curious as to why they'd change naming conventions. Is there any particular reason?
Short answer:
Because people in marketing are catastrophic idiots.
Longer answer:
This is the graphic to look at:

4K UHD has nothing to do with horizontal resoution. 4K is because its exactly 4 x 1080p tiled 2 by 2. (see how the FHD fits exactly 4x into UHD).
So 4K UHD is 4x1080p =~> 4K
By sheer coincidence 4K UHD at 3840x2160 which is sort of close to 4k horizontally 3840 ~= 4000 so lots of people thought it meant horizontal resolution rather than 4 x 1080p. To further confuse the issue there actually is a DCI 4K resolution 4096x2160 which *IS* named 4K for the horizontal resolution, which is actually 4K (4096 is 4k in binary of course).
Then when it came time to make the next standard, they did the samething as the did to make 4K. They just tiled a 4K screen 2x2. (Again see how 8K UHD is exaclty one quadrant of 8K... )... so 8K is 4 x 4K tiled 2x2 or 16 x 1080p tiled 4x4... but by then most people including the dipshits in marketing thought the 4K was the approximate horizontal resolution, so they called it 8K UHD. because 7860 is ~= 8000.
There are some other resolution standards in the 8K family that are derived from the DCI 4K... so they actually have 8192 pixels horizontally... well most of them anyway. 8K "21:9" keeps the vertical fixed and expands the horizontal out to 10,240... because why not. (I mean, I get it... but then 16:10 should have just varied the vertical and kept the horitontal... but that's 8192x5120... which isn't really consistent with anything.
I have two 4K monitors on my desk right now, both 28", as well as a 15" 4K laptop. On thing it adds (besides amazingly smooth looking fonts and GUI elements) is screen real estate. Even with the DPI turned up so text and icons look "normal" size there is a ton more screen space than you have on a 1080p screen. After using these for about 6 months now I have no plans to ever go back to 1080p if I can help it.
I browse on +1 so AC's need not respond, I won't see it.
