MBP 13" 2015 is unable to play 4k 60fps video?

- Probably, yes. I assume you have checked internet connection related issues. 4K 60fps is insane stuff.
- My more powerful 2011 quad-core has trouble, too. Plays for 3 seconds, pauses for 1 second, plays for 3, pauses for 1, and so on. How are your symptoms?
My symptom is that video stuttered randomly, it plays 3 secs and pause and then plays 1 or 2 secs and pauses again
No your computer should be able to play 4K 60fps, but you will need a bare minimum of 25Mbps ( more like 50Mbps to be honest for smooth layback) internet connection to stream it (assuming you are only trying to do that one thing on the connection).
If you have an internet connected 4K tv you'll be better off using the in built app, if you are using the MacBook screen then why bother it isn't a 4K screen just stream 1080p 60 fps it'll look just as good.
I tried to download and watch offline but the video still stuttered. My issue is the same as this video from another user:
- Can yours? Example. Note that neither Safari nor Firefox support it. You must use Chrome.
- Is that video supposed to be slow motion, or is that the way the problem shows itself for that user? Because mine is different. Mine plays smoothly for 2-3 seconds, then pauses entirely for 1 second, and keeps going like that pretty consistently.
Just to dispel the internet connection issue completely (it can be easily distinguished from actual playback issues, but whatever), I'm on 60/60 Mbps and can stream the video faster than it can play.
No ,that video is 4k 60fps, the issue is that it becomes slow motion on my mbp when watching offline. if I watch online on youtube, the video will stuttered
Looked at this video ( I think) and a few others.
Browser issues could be a source. I am safari so cranked up I got problems I expected to see, safari not on the list. Lower settings looked fine. 15' mid 15 mbp
Encoding can be an issue. Saw a few comments in a few kpop ones this recommended but I think it was this one where codec guidance was given as some issues at first. Some commentators asked for source in fact. An eye to other friendlier codec conversions assumed.
Also could be the software. Never worked with what they use. something about .lge output files. Quick googling seems to show one off converters for these. Youtubers didn't mention what is used in workflow either. Won't speak good or ill of them since never touched this. All I know is with my new entry into vdslr exporting is where things can just as get interesting just as well as shooting and editing. Video work has been more for home use and its an apple device house basically (if you take away a windows and couple Linux virtuals I have for testing in paralles lol). Only recently have I looked at tweaking exports for other setups tbh.

Mine is a 2013 with IRIS 5100 graphics I would expect it to struggle the 6100 in the 2015 is rated to run 4K fine.
, its mp4 tho. Think its maybe encoding related...I think it has to do with software. I downloaded a 4K .265 video in mp4 but quicktime wasn't able to replace it. Since it should be technically playable (according to Intel Broadwell is able to decode using a mixture of CPU and GPU) I'm guessing Apple hasn't placed priority in creating the software to decode it. Granted I played in same file under mpv but utilized 100% CPU and framerate was abysmal.
I see stuttering on anything full screen on a 4k monitor. Even playing a simple browser game like Agar.io isn't smooth. However if I shrink the window size it eventually plays smooth.
Why not? Why Chrome? The only thing there is to remember is to revert back to Flash for 4K playback, if you happen to have ClickToFlash installed. But this Transformers video plays back in my Safari without problems.
I tried playing the 4K 60fps video linked in post 9. This was with a 90 Mbps connection. It still will not play smoothly.
- YouTube ditched Flash a long time ago. It uses HTML5 by default now. Not sure you can even manually set it to Flash anymore...
The video might be playing, but is it playing in 4K 60fps? Check the quality settings in the video.

Not really. Try to use ClickToFlash Flash blocker and you will see. In HTML5/MP4 rendition, max resolution you can see is 720p.
To see 1080p or above resolutions, you need to switch back to Flash. It may well be just a wrapper around the H.264/265 video, but Flash is there:
In Safari, I see only 2160p, but not the framerate:
- I can see up to 1080p60fps in Safari with HTML5 (in other words, the standard player). Up to 2160p60fps in Chrome.
- You mind telling me how to force the Flash player? I'm curious.
(ClickToFlash is outdated and no longer supported in Safari, according to their website.)
- That means it's not 60fps. Nothing is stated if it's normal framerate, but "60" is specifically displayed when it's 60fps.
Like I said, Safari doesn't support it.
Dunno. Still works for me:
But you are right - the Flash player is phony. When running it without CTF, it allows me to select max 1080p resolution. When I run it via CTF and re-enable Flash, I can see up to 2160p, without framerate given. I can see the quality change to up to 1440p from there on not any more, because my monitor maxes out at 1440.

I noticed mine does this as well when I upload videos from my 4K GoPro.. At first I thought it was my memory card but the videos play fine on my 4k samsung tv so I assume it's my late 2012 rMBP that can't handle the graphics..??
