Administrator DKT27 Posted July 10, 2010 Administrator Share Posted July 10, 2010 Thought 1080p video on YouTube was big? Think bigger. YouTube on Friday announced that its player now supports 4k, a standard resolution for films that measures 4096x3072 pixels. As YouTube Engineer Ramesh Sarukkai explained in the announcement on YouTube's official blog, "4K is nearly four times the size of 1080p," and it dwarfs even Imax, which projects films in the slightly smaller 2k format, with its 2048?1080-pixel resolution. Of course, the proof of 4k's merits is in the pudding, which is why YouTube has a special playlist of five films that can be played back in their original 4k resolution. As Sarukkai warns, viewing these properly requires considerable bandwidth speed, as well as the right gear. Speaking of which, even with a fast connection, home users will need the proper equipment to enjoy 4k videos in their native resolution. This means a large display, or 4k-capable projector--neither of which can be had on the cheap. It's also worth mentioning that while quite good-looking, streaming 4k video still has to jump through some of the same compression hoops that lower resolutions of HD video must do, meaning that they'll be playing at a much lower bit rate than you'd see, if you were to watch it from the source. On smaller videos, this can be less noticeable, but when blown up big, compression artifacts can be easier to spot. 1080p remains top size in most consumer HDTVs, as well as the service's previous resolution limit. Newer-model phones like the iPhone 4 and HTC Evo are just now becoming capable of shooting in the lesser 720p resolution, leaving 1080p and above to dedicated filming hardware.A 4k video in YouTube. 1080p--the previous YouTube size limit--is approximately a fourth of the size.

DreamHaters Posted July 10, 2010 Share Posted July 10, 2010 Wait why? Most people are just getting 1080p monitors and they release stuff that not even Imax has. Link to comment Share on other sites More sharing options...
Jared Posted July 10, 2010 Share Posted July 10, 2010 I guess it's just a technology people just want to push to it's limit. It's exciting to be able to think that, at some point, cinemas will be projecting such high definition video, moreover, the speed this will pick up when it finally becomes a stable form of media.I'd give it two years at most before this is the *new* thing in disc form. I mean 3D has been around for a while, but only now have they got TV's which enable it to be viewed at home, so there is hope for this yet.
