I have recently tried downloading 4K 60fps content from YouTube.
I'm having hard time playing them in vlc or any other player (i've tried 5K player).

I am downloading the videos with IDM, the options above 1440p (Starting 1440p 60fps and above) are available only as mkv downloads, and those are the ones i am having a lot of stuttering, blurry screens frame losses etc while playing.


I've also tried playing with a few preferences in VLC sometimes it works, sometimes it doesn't.

I'm basically downloading these 4k content to put them as animated wallpapers on my desktop with Wallpaper Engine, and the program does not open mkv formats.


Any idea how to make this work?

I have sli GTX 980's
1440p monitor @90Hz
Intel i7 2600 .
Thanks for the response.

MPV played the video flawlessly.

Now,
Any idea how to download these videos from Youtube as MP4 files to use them with wallpaper engine?
I appreciate your help tmash2,
So could you please guide me on how to convert the files to mp4 (or any other format that works with wallpaper engine, I'll provide the list later) without losing the quality?

On another note, I downloaded an 8k video, tried playing it, ran into same problem with stuttering frame loss etc but this time with my cpu usage at 100% lol.

Just a technical inquiry, as i didn't want to open a new topic for this.

Why won't my PC play videos above 4k resolution? (whether was it streaming or video files).
Basically anything above 4k (starting 5k and up), the video is freezing and my cpu usage is at 100%.

My specs are:
i7-2600 @3.9Ghz
GTX 980 SLI
24GB Ram

Oh and a 2k Monitor @90Hz.

980 SLI is feature set E 4096p max
Hmmm, Thank you for all your help.

So basically you're telling me that the 980 cannot display video Playback more than 4096p.

Although i saw some Games being played at resolutions more than 4k reaching till 8 and 16k with an 980ti (which is still feature set E as i saw in the list. Yes, with unplayable frame rates, but still being played and not completely freezing.

I'm not an expert but i find it weird that the GPU is being able to play and render games on resolutions beyond its limit, but still not being to playback videos at those resolutions.

(Encoded) Videos are decoded then streamed to framebuffer or render (sw compositor) games are rendered on GPU then sent to framebuffer. Two different things two different proccesses. My 7th gen NUC Intel HD can play HEVC 10bit at 4k 60hz, and 8k h.264 at 0% CPU usage since a hardware decoder exists for this type of codec, GPUs can have multiple functions and multiple components. (There are even dedicated decoders out there like the broadcom crystal hd decoder for old netbooks using mpcie, optimus-like streaming to the integrated graphics, same thing with RED rocket x) Most modern GPUs (since more than a decade now) integrate a hardware media decoder, in your case its limited to the specs indicated on the wiki. E.g if you add gtx1050 and set decoder to chosen GPU (1050 as it supports 8k) it will run fine even if the video output and master GPU is 980. Not all players support this option though. (MPV does)

Edit: typo and clarification
Understood.

So, now, in order for me to play those videos at 4k and higher, i need to upgrade my GPU to the new 1000 series i.e. 1070,1080,1080ti etc as i saw they were in the list of gpu who are able to play up to 8k.

Or, correct me if i'm wrong,
If i change the cpu to a newer generation like kaby lake or the new currently launching ones coffee lake.


Personally i'm not planning to change the GPU's, but have been thinking for some time now to upgrade my cpu.
If upgrading my cpu will indeed allow me to play those videos at 4k or 9k then it will be lead me towards upgrading definitely.
tmash2 wroteYou need an astronomically powerful CPU to decode 8k with regular players in realtime as the time of this writing. Unless you meant by using the new integrated graphics decoder.
Yes i meant that.
Inter Quick Sync Video as they call it.

Its says that the latest kaby lake processors added H.265/HEVC Main10/10-bit encoding and decoding acceleration.
But it didn't mention the resolution.

Does that mean that i will be able to play 8k videos depending on kaby lake / coffee lake?
