Can the new Macbook Pro 16" play this video without lag?

[jerryk]

Interesting. After playing the vide

Yes of course it can, Firefox support VP9 code, please see attached screenshot. 8K (7680x4320@60) 0 frames dropped!!

No way I can playback this with my 2015 MBP 13" haha

That is the Japan video that played buttery smooth for me. The question is on the Peru video referenced at the top of the thread. And the browser in question was Chrome, not Firefox.

But, I actually think the issue with the Peru video is the YouTube servers ability to feed the data. After I played it few times on my system it pays buttery smooth at 8K. My guess is the file gets cached on my machine by the repeated plays.

And it plays fine in Firefox with 8K, but not in Chrome.

BTW, do I have to install something to get 8K support on Firefox?

Ahh Ok sorry I missunderstood. You are right for some reason I'm only able to playback Peru video in 4k. Cached or not doesn't really matter as still needs the GPU computing power to be able to playback any 8k or 4k video. Codec plays a big role here as H264 is very inefficient.

lol my base imac 2017 intel struggle on 2160 .. only survive smooth on 1440.. and ipad the same 1440

High definition videos like 4k and above need a proper desktop graphic card, maybe an eGPU.

No problem with my MBP 13 late 2013 in 4K, I think the problem is from VP9 codec that is poorly optimised.

Can you playback 4k youtube videos with 2013 MBP or you mean 4k movies?

4K vidéos on my computer, I have safari so no 4K on youtube (and I remember a time were it was possible and it worked fine).

 

[junkw]

It's called 8K because you need to spend 8K to play it

So what are the reasons that the i9 MBP cannot play the video smoothly? The MBP 16" I got (i9, 8GB VRAM, 32GB RAM, 2TB) could not play smoothly.

Supposing a laptop has a 4K screen. Does it make a different playing the 4K vs. 8K versions of the same video? Do images look better on a 4K screen when playing the 8K version, rather than the 4k version, of the video?

There's no reason for it to not play it smoothly (unless your network speed is too slow to keep up). It should play it back no problem...

Tried both videos on the 16" and it can't play the 8K version of either without stuttering every few seconds with a spinning circle. Tried it on my base model 2018 Razer Blade 15" and it played flawlessly (in Chrome). A little annoying if I'm honest, but I wonder if it's not some kind of bug. All of the CPU cores seem to be getting hit pretty hard on the MacBook Pro. EDIT: I have the higher tier base model MBP with the better video card for what it's worth.

 

[BootLoxes]

My 7700k 1070 pc runs it flawlessly. Also I finally now know where all those TV demo vids come from. That said it surprised me that the MBP 16" couldnt do it

It does not have the appropriate driver. It’s really simple, really. The reason behind it is not technical, it’s political - part of ongoing codec war between Apple and google.

 

[vemac575]

Specced out 2018 15" Macbook Pro. It would pause every 3 seconds, for about 2 seconds on 8K, but played 4K with NO problems.

I don’t think so. The 8k version plays perfectly smooth on my iMac Pro.

Play it 2 or 3 times and see if the results change. On my machine it became smooth suggesting the issues is not with the graphics, but with getting the bits down to the system.

And yet is is the truth. The video in question is using the google VP9 codec while Apple is pushing HEVC. So it has to be decoded in software, placing unreasonable burned on our CPU and degrading performance. Maybe your iMac Pro is fast enough to decode it in software properly, I have no idea.

Still, the answer to the question "why can't MPB play it without lag" is "because Apple does not ship a hardware accelerated VP9 decoder".

You can read more here or just google about Appel and VP9

I don’t know, I just have the base model 8c iMac Pro. I would think that an i9 in a MacBook should be comparable, so that’s weird. 😲

This is very interesting. My ex-MBP 16" had i9 and 32GB RAM. It could not play that video smoothly. Lots of pauses. However my Windows laptop with i9, 16GB RAM and 4K screen can play it smoothly.

Which browser on windows? Windows ships with support for VP9 and the default Windows Edge browser has support for VP9. Now that Ballmer is gone, there is a lot of bi-direction research and code sharing with the software and hardware teams at Microsoft and Google.

The peru video - I am curious if the new MBP 16" can play it at 8k @ 60fps HDR?

You may need to install chrome to see the option for 8k:

On a PC/Win10 with ~1650 graphics card it uses ~80% of the GPU but CPU stays close to 0%.

Streaming Compressed 8K is pretty useless.
try using the Hard file copy, of H.265 VP9 10-bit HDR10 7680x4320 source file. Which can be like 40GB for a 11 minute clip.

Let me know if you MAcBook Or PC can run that file.

Only way my PC was able to run it was thanks to 32GB DDR4 3200mhz RAM and a 9700K OC to 4.9Ghz ALL Cores and a RTX 2080 Ti and running off a 1TB WD Black Nvme M.2 at 4x PCI Express 3.0 3500Mbps Read Write.

The default Edge I believe.

Well of course, you have hardware accelerated VP9 drivers for windows. I’m fact, I’m sure that the same Mac running boot camp will play the video just fine. Can someone try out?

Again, I do not know why your oMac can play it without lag. Maybe the software decoder can take advantage of the AVX512 support on the iMac Pro Xeon, or maybe it’s something else. Regardless of that, this “issue” has nothing to do with performance, just competition between rival formats.

 

[hajime]

Another test: Using the same Windows laptop that can play that video smoothly, test if it can play the same video smoothly as a Hackintosh? If not, then it is software related issue.

Just tried, smooth like silk..
