4k Video Comes on YouTube
YouTube's player now supports 4k, a standard resolution for films that measures 4096x3072 pixels.
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.
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.
