Yes, Google Chrome is required to view them on a desktop.

i tried downloading the first video using 4K Video Downloader and the highest resolution option that came up was 1080p/60hz

Anybody recommend any other sites or tools for ripping these to a format that will play on the tv?

Ugh.

Does anybody know if these YouTube videos have any other tech spec than 60fps? Such as HDR, REC 2020, 10 Bit video, 4:2:2/4:4:4?

Also what codec are they using?

I have heard that Safari will work as well but I don't use it or Chrome for that matter so I can't check.

And does it really matter? Youtube absolutely destroys video quality by squeezing the life out of it.

I've seen 4k uploads that looks worse than Blu-ray.

I do agree with you I was just curious as a article on another website says they struggled to play them with a Geforce Titan 21Mbps internet connection.

Interstellar will be in 4K

the biggest problem with youtube is that it's not using the H.265 codec. 4K videos are absolute dogs in H.264

With enough bit rate, AVC is fine for 4K. With low bit rate online encodes, not so much.

that's what i mean though, H.264 is so inefficient that to get 4K video into a manageable package online takes far more compression than a 1080p video.

I've downloaded a few 4K youtube videos, and even though they use the same codec they are nowhere NEAR 4 times the size of the 1080p videos.

If they were using the H.265 codec the quality would be much higher.

But 4x the pixels doesn't translate to 4x the file size, not with video compression involved, because of the increased similarity of adjacent pixels in any given area of the 4K image vs. 1080p. Besides, as the Freakosaurus said, youtube is compressed to shit anyway so anyone using that as an ultimate arbiter of what AVC can do with 4K needs to look further afield.

Why? So 4K can look like 2K?

[tyrok]

Will 4K 3D Blu-rays be a thing or is that just too much to fit on a 100gb disc?

There is no 4k 3d content

Whether it is suitable or not I have had enough of all the apple shit.

The spec for it now exists though.

VP9 allows for 10-bit, 12-bit, 4:2:2, 4:4:4, and the Rec. 2020 color space. I don't know if/when those features will be seen on YouTube but VP9 can do it.
