4K 60p coming to YouTube at DVinfo.net

Disclaimer: the video linked in the story was EDITED in a 60p timeline with 24p sourced footage. It is not a proper demonstration, but it proves it's possible to a select group of people. In this case, NASA.

Do keep in mind Google WANTS you to use their VP9 codec instead of H.265 to decode this at 60p, (they give you no other choice, it's VP9 or bust) hence there are no current hardware decoders for VP9 fast enough at the moment to decode the full resolution and frame rate. That would be a year down the line when people like Nvidia, AMD, and Intel start to implement hardware VP9 decoders fast enough.

Also, if you look at the reel they later posted, for standard videos, they're starting to shrink 4096 to 3840. Those shooting for the web, you must shoot for 16:9, not the ideal 17:9.

I still can't get 720p60 payback from YouTube. It is always stutter, stutter stutter on any camera movement. Kind of over YouTube as a delivery medium. Always defaulting to low resolutions and choppy playback. I have tried the HTML 5 player and it did not improve much. It is what it is...

16:9 is ideal for what the overwhelming majority of shooters on this forum will be delivering to.

This is because Google wants you to use their VP9 codec which not a single hardware acceleration chip for PCs have support for. Even in Chrome, it tends to stutter. There is no 60p option for Flash too.

I seemed to notice MACs played online videos a let better than PCs. How could such a large section of the computer world be left out of Goggle's product? Crazy and it does explain why I have never had good playback online. Is this ever going to improve?

Is that video you linked to causing you playback problems? On my pc it plays fine up to the 4K resolution, eventhough my screen is 1080p only.

Once I get the raw WEBM file and play it in MPC-HC, smooth as butter. But playing it in a browser is never going to work smoothly cause they're not optimized for video playback, especially if your CPU is doing all the work.

Same here. Straight off YouTube in Chrome at 4K 60p on my MacBook Pro 15" Retina. Plays back fine for me, over WiFi no less.

I just tried again to play that file in a chrome and opera browser and in both cases the 4K file played fine, no stutter, I have a i7 3770 processor and processorload during playback was around 70%, the second video after that was also 4K and the processor load dropped to about 30-50%, not sure why it was higher in the first video.

Plays OK in Firefox or Chrome on my PC. i7 3770K, WIN 7.

On my computers YouTube always looks like they have a variable frame rate option in the encoding. There are always micro stutters as I saw in this NASA clip. Even though they are saying it is 60p it does not look like 60p on a television or Blu-ray. I don't have a smart TV to compare with. Maybe it is just computer vs TV screens.

I don't know but there is a difference between "plays back fine" and looking like broadcast 60p. As with a lot of things on the internet, the bar seems to be lower.

The bar is not lower on my end. Full speed on a 27" 1440p display that I sit two feet away from. Looks like broadcast 60p.

Could you do me a favor and watch this clip? It was uploaded in 1080p60. It stutters like crazy when I watch it on YouTube.

The opening animation isn't very smooth (not sure if that's source or not), but otherwise plays fine for me for the most part.
