eh? Thought they already streamed 4K? I've watched a lot of 4K on their already... maybe they are updating their hideous compression?

YouTube has had 4K for many months. I've downloaded some content for a neighbor who naively bought a 4k set thinking she would get better quality, but now finds that there is zero content available. All she has been able to watch are the thrity-second demo files stored on the set.

Here is a link to some current YouTube 4K content:

Youtube 4K

I cannot get YouTube (or Vimeo) to give me decent 1080p streaming over a 12 mbps connection, and many people on this forum with even faster connections have reported similar problems. I can't imagine what sort of stop-and-go quality people will get with 4k.

As I said in another thread, this is an acquisition play, and use as a consumer delivery format is a long way off. I watch the 4k stuff on my computer monitor and the quality improvement over 1080p was impossible to detect. When used for delivery rather than acquisition, this is a format for theaters, not home screens.

+1.
Plus Youtube, and others, 1080p bitrates are pretty low. 8Mbps at best.

Heck my FIOS cable is only fair. I see pixelation often.

Give me decent 1080 before moving up.

This is the video equivalent of the digital camera megapixel race. More is better...right?

I just tried playing one of YT's 4K clips (Skydive Dubai 2012) and it streamed perfectly ! That's from the other side of the planet on a pretty low end PC. No artefacts, in fact given the nature of the content some of the cleanest footage I've seen on YT.

Interesting what YT are doing, they seem to be supporting Scope natively as it's flagged as 1440p. Now this makes a lot of sense and is where I'd suggest 4K distribution makes a lot of sense keeping in mind that Scope at 2K only gives us around 700 lines of vertical resolution.

Bob.

I just tried playing one of YT's 4K clips (Skydive Dubai 2012) and it streamed perfectly !OK, what's your secret??

1. What bandwidth connection?

2. What browser?

3. What version of Flash?

Do you have any other hints or advice?

I am very jealous ...

I just watched a couple of the 4K clips here and they looked great without a single hiccup:

20Mb cable connection - IE11 - Flash 11.9.9

OK, that's two people who are getting good results. Did both of you click on the YouTube quality icon (lower right corner) and make sure you were actually streaming in 4K rather than 1080p, 720p, etc.? I just can't believe you are getting results so much better than what I'm able to achieve. YouTube defaults to much lower resolution than 4K to you definitely need to change this manually if you want to get the 4K (or even 1080p) version.

Woah! - Well I can't put THAT particular Jeanie back in the bottle!!! How does YT do that?

Watching now . . . . . . O-M-G!!!!

I just back peddled through 1080 and then 720, just to make sure . .. . eh, not so much.

G

Here's my iPhone snappy!

OK, I guess the problem is on my end. I'll have to figure it out on my own.

BTW, 1440 is not 4k.

John? Am I correct with those numbers? It's higher than my usual 1080p?

It looks amazing. If I can help - I can't think HOW give us a shout.

G

Yeah.....

So where do I spot that 4K number then?

G

Breath out and . . relax...

For what it's worth...
I can bring 2.5k ProRes and DNxHD from my BMCC directly into Vegas and edit, but I can only output (render) to 1080 from Vegas. With the handy dandy Davinci Resolve that came with my BMCC, I can output to 4k, 3k, 2k or 1080. I suspect not every NLE allows for that and some may be rendering out to values less than 4k and uploading to YT where it sees a value greater than 1080 and some are confusing that with true 4k. It would be interesting to know if VP14 will allow output up to 4k.

my 4k youtube streaming always seems to buffer: 50mb pipe at office, or 20mb at home - always stops and buffers when 4K is selected :/



and I am only watching on 1080p laptop screen.

you can also downlaod 4k footage using keepvid.com (IIRC) to mess with inside vegas - but it has YT compression on it already

[I]my 4k youtube streaming always seems to buffer: 50mb pipe at office, or 20mb at home - always stops and buffers when 4K is selected :/[/I]Yes, that is exactly what I am experiencing. However, at least two people report they are getting it to work smoothly. It will be interesting to see if anyone has an idea what we are doing wrong.

[I]"BTW, 1440 is not 4k"[/I]

You're right, it's 2560x1440, the latest standard for mobile phone screens.
It's also known as WQXGA.

I have tried other "4K" videos and had no problems streaming them over our 20Mbps cable connection. I suspect we don't have any heavy users sharing our cable segment. I'm just using the latest version of IE and Flash on a 2.67GHz i5with 6GB of RAM with a GeForce 220.

Bob.

And now I have 4k. See the next piccie.

G

and you did select 2160p 4k on the Youtube settings?
I just checked our work network again: 13 ping, 45mb down / 17mb upload
STILL can't stream 4K smoothly.
This is all getting very interesting....

does the little white "Loading" bar stay ahead of the red playback location thingy?

maybe provide a link to one that streamed smoothly?

I watched these two (earlier today -- no buffering issues):





I just watched another one (had 1 buffering pause about 2 minutes in lasted about 4 seconds)

I've closed down for tonight.

I'll apply an analytical, evidence-based approach tomorrow and get my brain into gear.
