set the quality to original and enjoy
hey whats up, my youtube displays only the lower quarter of this youtube video. How do you fix that
Hmm, I'm not sure my Internet is capable enough to stream that
Nice, run flawless @ 23 to 25 fps.
need to get myself to the apple store tomorrow and try that i reckon
Took several minutes to buffer enough to play smoothly on my 50mbit work connection. I feel as if the internet is not ready for 4k yet. Or maybe it's just YouTube's crappy servers.
Same for me, the internet is not yet ready.. thus the need for google fiber.
The vid bitrate is *only* at about 23 Mbps. Most common Internet access give enough bandwidth.
The video looks nice. Although to my old tired eyes, it is marginally better than 1080p. But one item, I did notice was that even the smallest details were visible, such as eyelashes, leaves, hair strands. It looks very natural as if I was standing there myself and looking at the scene. Maybe that is what 4K is all about, blending the lines between what I perceive as an image on my TV or screen and a real life image that I am physically present and looking at. Hmm.
Side note: YouTube was very fast to down load the file, only took about 15 seconds for the 830MB file as I was getting ~180MB/s speed.
There are some comments on the video that youtube doesn't support 4k and only displays 2k, is that correct?
Either way the video looks real nice on my rMBP. However even with a 35Mbps rated connection (which is actually running at 60Mbps this second), I was getting a half second buffering every 30-40 seconds.
youtube can be finicky. I have a 35 Mbps connection and youtube occasionally has trouble with some low quality videos. My connection is fine so i know its youtubes servers that suck. Im starting to think youtube is getting more popular then it can handle.
It's been this way for a long while. Even before I upgraded and was on a 20Mbps line, youtube would struggle with 480p trailer. Just don't think they have the capacity that they need most often.
I noticed pretty much the same thing myself. The thing about 4k is that it doesn't really get noticeable much over 1080p until you get into much larger screen sizes than out 15" notebook computers.
Take this same video and put it on say a 60" display capable of 4k and you will definitely see a difference between it and a 1080p video on the same size screen.
My connection (50mbit cable) had no problem streaming the video. I can only confirm the experiences of the posters above me: subjectively the video looks only marginally better than 1080p, but at the same time it just looks so... natural! It is a very weird sensation. But my brain clearly prefers the 4k.
It runs noticeably smoother using the GT650M than it does with the HD4000- at least that's what I found.
Also nice smooth HQ here, no pauses, no dropped frames. 30MBps FIOS connection.
Those fans ramped up quite a bit there for awhile, and she got a bit warm. Must have been enjoying it.
Frankly I couldn't tell the difference.
Mine was all smooth and loaded fine in 4k. But my fans stayed quiet and my computer wasn't warm...
I had forgotten I still had fan control set to turn up the fans early and based on GPU temps.
Did anyone notice YouTube tries to downsize to 2048 x 1536.
Possibly being a bit dense here but I can't see any quality settings anywhere. I played it and it looked great, really fantastic. It didn't have to buffer so perhaps I didn't even get the full 4K version. My internet connection is rated as 16Mb/s and we usually get about 13-13.5Mb/s.
Whether I got the full resolution, it was a treat for the eyes. Thanks
EDIT: I have Flash blocker installed. Don't know if that might explain not getting quality settings...
If you're in the HTML5 trial you will not get the "original" quality setting. So yes, 4k is in Flash only at the moment afaik.
Don't you need to change to Max resolution (3840X2400) before watching this Video with a program such as:
Runs fine on my 13" rMBP. No frame drops
Yes, this is correct. Even in "Original" mode the video is nowhere near actual 4k quality (both in bitrate and resolution). I believe it cuts it to 2048x1536. In order to get the original 4k resolution, you must download the original .mp4 video using whatever method you prefer (I use jdownloader).
Using the OP's youtube link, the original 3846x2160 video file is 792.38 MB (compared to 170.14 for 1080p). There is a noticeable difference between 2k and 4k versions.
I'd also recommend you use VLC to watch the video and not QuickTime X. For whatever reason, Quicktime X seems to output the video at the "perceived" screen resolution (rather than the retina-aware pixel matching native resolution like VLC). I could be wrong about QuickTime, not sure why Apple would have it report a bogus resolution in the "Movie Inspector" window.
After watching the original video, it's not a very good example of 4k. Checkout the video at the link below (you have to download it by clicking "Stahnout" below the video). The file should be 264.7 MB for 43 seconds. It's a much better 4k example with a 120 Mbit/s bitrate.
