I've got a pretty high-end PC in the office with gobs of memory and even after it's downloaded, it won't play the video without stuttering. It can take 45 minutes to download an Apple "HD" video from iTunes. At this resolution, a feature film would probably take several hours over my 10MB connection.

This is why physical formats are still necessary (although there is no viable, standard, commercial format for 4K video).

But it's nice that YouTube is accepting these resolutions.

Same thing, I have a nice gaming PC that I built but it skipped frames like crazy when I tried to play this clip. I switched to 1080p, it looked the same and played just fine. Btw, I'm running 1980x1200 on a 28" monitor

As high bandwidth connections and more powerful computers become more common, viewing media online in these resolutions will be awesome

Full HD PC monitor now becomes mainstream products for the regular desktop PC, but most of Notebook's LCD can't reach full hd.

Can't be too high end of a machine, as my i7 920 OC'd to 3.8ghz, with 12gb of DDR3 memory played it flawlessly. And from my connection, it took only 20 seconds to download each of those sample vids.

Unsurprisingly 4K absolutely slays my Core2Duo MacBook *shrug*.

I find it pretty hilarious that even at 4K, they're still using the same audio as '360p': AAC 2.0 @128kb/s. Who's genius idea was that?

Exactly, it seems pointless until a 4k monitor is used to view it. I wouldn't even attempt it on my high end gaming tower.

Very sweet but not useful at the moment. Pioneer can always build me a 200" Kuro. (I wish...)

4k resolution and its download size is only 268MB, well, the video is only 1m54s, though.

When's in HD everything looks much better and clearer, I've got 1080p FullHD, so no intention on getting more than this.

I just tried watching the video on its original size [4k] on my PS3 and it didn't show anything, I knew it wouldn't but still gave it a try.

Heh, will dl the 1080p and see it, wow big difference, 1080p is only 47MB.

The thing that bothers me is how are people going to get even HD quality onto their screens (i have a Panny 50 inch plasma) when/if all this downloading/streaming crap
takes off. Don't get me wrong i still think Bluray has at least ten more years but i am only 36 and i wonder if there will be a time when we don't need hd tv simply because brainless people will prefer streaming and downloading. If all cable, satellite is also overtaken by streaming that would mean all us purists wouldn't really have a point for hd 1080p televisions because there would not be a high def source to watch it on. I can't hack streaming quality on my current plasma.

Wow..... dramatic much? I already have a few hdtv's, but if you are so convinced that yours will become useless thanks to "brainless" people; I will consider giving yours a proper new home.

But to address your points. Every movie ever made is not on blu-ray... nor will they EVER be. Actual entertainment fans embrace all of the options available to them to see the wide variety of entertainment they desire. Format fans only want to see the relatively few (when compared to all the movies ever made) things available on blu-ray.

First, there are TONS of great movies in the world that will never come to blu-ray... nor would a blu-ray treatment even do them any good. They weren't filmed in a resolution at least as high as 1080p and they only have stereo or mono audio. Streaming is a fantastic way to view these movies.

Second... there is a LOT of high def streaming content. TONS of it. Vudu, Netflix, Hulu, Zune and others all offer hd content.... some of it 1080P... there's even some HD 3D content available for streaming these days. HD refers to the resolution only. What you are referring to is compression. Now if it is compression that you think makes content non-hd, there already is no hd content for you to watch on your hdtv. Go ahead and chuck it now. Cable, satellite... and yes even blu-ray all use video compression.

Please do not insult my intelligence by telling me bluray is compressed. I know what bluray is and indeed i do consider the compression the key factor. By the way i have yet to see a stream that can compete with satelite hd here in the uk. Also i have hundreds of dvds so i already own a vast collection of films. I also have hd sattelite with a pvr so i am not short of options. The bluray image is by far the best image i have ever seen outside of a cinema. To have people tell me streaming is hd quality is simply a lie.

I guess I'm not an "entertainment" fan because I think 99% of the TV shows on are crap. I'm fine with that. I like movies.

A lot of movies weren't "filmed in 1080p". They were filmed, analog style. The resolution is in the transfer to digital. Want some proof? How about "M" (1931). Looks much better on blu-ray than DVD. How about "The Wizard of Oz" (1939). It wasn't "filmed in HD". It was filmed. From your argument you don't understand this...

Sure there is lots of HD streaming. But resolution is not the end-all be-all of quality. What is the bitrate again? The very best quality HD streaming (VuDu) is not as high a bitrate as a good Blu-ray disc transfer. Reign in that rhetoric. Just because it says it's HD doesn't mean it's all the same. Case in point Youtube. Their videos look like crap on youtube, even in 720p resolution. Super huge compression and artifacts. Yes, all HD is compressed. That doesn't mean it's all the same, far from it. I could take a .jpg image and save it with 90% quality and at 50% quality... think you could tell the difference?

Lastly, do you honestly think a company who streams a movie is going to spend hundreds of thousands of dollars on a new HD transfer or comprehensive restoration efforts? Will their customers, who already accept lower quality even know/care/notice the difference? Will streaming FUND such efforts like BD sales do?

Here's an article I found from 2007 (four years ago!)
Quote:
Blu-ray and HD DVD movies are presented in 1080p. In several cases, the movie studios also go into their vaults and mess around with the video to optimize it for high definition. This is the kind of meticulous detail that’s overlooked for over-the-air HD content, which is usually either streaming live or a bland regurgitation of something recorded on HD video cameras. Watching the same movie on HBO HD and on Blu-ray Disc will actually result in a big difference, in obvious favor of the Blu-ray presentation.
