youtube 4k is out :D

[AstroZombie1]

Give me 60 fps videos instead please google. 

[JAKEBAB]

is this a joke? this is like months old even when people posted 4k videos on here it was old!

Original quality would stream at whatever your bandwidth could handle if I remember right, not just 4k

Nope, original quality is whatever the video is uploaded at. YouTube reencodes the video to lower quality resolutions. Original is no reencoded at all (past the original rendering).

Well it is reencoded to reduce the bitrate, but the resolution is left unchanged. I am fairly sure that the rumours that you would get better video quality by setting it to original were false unfortunately.

If I'm not mistaken, "original" quality in YouTube secretly only went up to 3k or something, although I could be wrong.

Hope you like my vid in 4K lol.

 

That's 1440p, not 4K.

[Equlix]

so they can do 4k but not 60fps? or 1080p without terribad encodeing? wtf youtube.

my Phenom II (4c/3400mhz) and my 7850 can handle this 4K YouTube video (yey i am in the 4K age) 

 

 

(my connection does not)

youtube needs to fix a metric fuck ton of shit before they even THINK about releasing 4k.

2160p is rather new. Previously, it was just 1080p, some rare instances of 1440p and then Original (which could mean anything ranging from resolutions greater than 1440p, 1744p, 2160p or much greater). Blender's 4K Sintel (2010) was marked as Original, though it was only 4096x1744. I suspect 2160p specifically arrived due to a certain hardware, but it could be a coincidence. A lot more content creators will look to upload 4K videos now, though... As a side note, these 4K videos are limited to 24/30 fps.

4k is not 4 times the resolution on 1080p..... 4k is 3840x2160. 1080p is 1920x1080. 4k is twice as much as 1080

 

I'll teach you some math.  3480x2160 is 2^2 (two squared) times larger than 1920x1080p.  You are correct in that 2160 is 2 times the size of 1080.  However, a screen resolution is a "squared" measurement.  Remember when you calculated the area of a rectangle in grade school?  Multiply width times length, for example 5 meters times 8 meters, and the area is 40 meters *squared* (not 40 'plain' meters).

 

Finally, 2^2 is two squared, or 4.  This means that you can fit 4 1920x180 sized rectangles inside a 3840x2160 rectangle of similar measurement (in this cases, pixel count).

All videos are limited to 24/30 fps (or 29.97). 2160p/4k has been added to the list now because some people will be getting 4k monitors now, and soon it will begin to actually be popular (few years).
