Can you try this?

So I played it just fine.

It's a bit of a jaggy video because the camera is jaggy. But I played it over and over on several different sizes and on my M1 16" max laptop and it plays the same on all of them.

Which is to say perfectly. I even blew it up to full screen on my 8k 85" monitor, played fine.

I just tried this on my 7.1 16 core with 6900xt and its smooth as silk. Maybe the guy who sent link has other issues. but would imagine yours should play it ok.
Hmmm, well it played back just fine on my system, and that was even just in the preview window with spacebar...so if your concern is playing files that are this one you've linked, then you're fine...

That said, the solution I use is my Mac Pro 7.1 is for GPU INTENSIVE WORK. It absolutely smokes anything and everything that doesn't have minimum 3 RTX 3090's in it when it comes to GPU accelerated 3D rendering, which is about 60% of what I do. But then there's the other 40%...which is editing, and for that I use...well I still use my Mac Pro mostly lol, cuz it's damn good at that too, but when the footage is a codec that doesn't play nicely, my MacBook Pro M1 Ultra crushes anything and everything I throw at it, which pipes right into my monitors as well when needed for editing.

There's ZERO chance of me moving on from my 7.1 anytime soon, especially considering looking to the future, the RTX 4090's are roughly 30% faster than the RTX 3090's, which places my machine in it's current state "2 w6800x duos, 28-core" roughly ON PAR with 2 RTX 4090's.

THAT SAID lol...An article just released today where Mark German claims Apple had an M! Mac Pro ready to ship months ago but wanted to wait for the M2X to do it, and that a Mac mini Redesign is unlikely...SO...if they are going to allow me to bring my w6800x duos over to an 8.1 Mac Pro that is powered by an M2X but happens to play nice with MPX Module GPU's and can perhaps 4x my 28-Core CPU...yeah, I'll drop $52k on that day 1 for sure.

Online is 4K too.

For this 4K clip, bitrate is about 350Mbps. If people do online playback, make sure your Internet download speed is 500Mbps or faster. Otherwise, I suspect you won't have a meaningful test.
Online streaming is completely another codec / format / bitrate.

My hotel network (even using LAN) only has about 15Mbps, I can still play that online version smoothly. Sure that's not the same file as the offline version which takes 40min for me to download in the hotel.

28 core with W6800x Duos? I would be surprised if it does not play everything... :)

LMFAO! To be fair, yeah lol. I'm not gonna lie though, I'm salivating at the possibility of an M2 Mac Pro that is PCIE equipped and MPX module GPU compatible LOLOL.

Spent a bit more time digging in. While codec, color space & etc seem the same, apparently you're correct about bitrate.

I managed to download the streamed version. The bitrate is drastically lower ~20Mbps but still 4K. No wonder an ancient 2011 iMac can smoothly playback in QuickTime.

Both versions (~20Mbps & ~350Mbps) are VBR. I would assert that when stuttering happens, the scenes are a bit more complex, and the bitrate overshoots certain threshold where the software decoder starts choking on less capable CPUs.

But I'm still puzzled modern CPU like Intel 10th gen runs into such issue.

Alright guys I need some help here. I’m a pro video editor working on FCP (proxy-less workflow) and I have an employee that edits next to me and I’m upgrading their machine from a iMac 27” to either my newish Mac Studio Ultra or my 7.1 Mac Pro. Although to be honest I need some help deciding which machine to use OR possibly upgrade my 7.1. I’ve run a lot of real life editing tests which I mention below. Keep in mind I own both and I’d like to keep them separate rather than use my employees machine for points where my 7.1 is lacking.

Let me know what you guys think! All in all I love the 7.1 but it is a work tool and I need to be using the latest and greatest to work efficiently as possible. The Mac Studio as noted above is 5-10% slower for my workflow in most areas than my $16,000 7.1 Mac Pro, pretty impressive work on apples part considering if you maxed out the Studio and got 1TB internal and used an external drive you can get the whole 8K video editing machine for $5,800. Totally different machines but I’m impressed.

I would get a second M1 Ultra Mac Studio, and then start planning/saving for a M2 Extreme Mac Pro...?

Also plan to upgrade your network to take advantage of the 10Gbe ports in the 7.1 Mac Pro & Mac Studio desktops & the forthcoming ASi (8.1) Mac Pro...!

Ok we got a little off the rails here but basically I still have not decided what to do with my computer however I think I will just wait for the AS powered Mac Pro and buy that. Every way I cut it with spending money on my 7.1 really doesn't make sense. Will update the thread as I decide to hopefully help others in a similar scenario. My 7.1 is here to stay but possibly just as a server.

If only a future AMD card for the 7.1 could add better 10 bit 422 h265 support… it would really extend its lifespan!

Or yes sorry I was talking about offline playback of course. It is a 2.1 GB file to be played in FCP, or VLC or QT, Resolve or Adobe Premiere Pro.
Very strange. I got 4 video cards installed. The screen I now played this is connected to my W6800. W6600 is mirrored to that display, but not physically connected. W6800 is connected to both Samsung TV (4K and the display 1080p). 6900XT is connected to the Samsung TV (4K):

Now the funny part. Previously I was trying to play this video (downloaded) through the 6900XT and it was choppy in every player. Now it plays smoothly in QTP (still choppy in FCP). And according to the Activity monitor it uses W6600 for playback... Go figure.

If I open it straight in Compressor it plays fine. If I export it from FCP to Compressor it plays choppy.

GeForce RTX 40 Series use the same NVIDIA Decoder as RTX 30 Series - 5th generation NVDEC. There is no support for 10-bit 4:2:2 decode.
So much for the NVIDIA (or AMD) providing 422 subsample support with the newest cards. Stick with M Macs or Intel quicksync 11th and later generations for that decoder.

Wow that's unfortunate. Let's see in November if AMD uses same decoder as RX 6000 series.

It's sad because Intel's ARC GPU actually has the best media engine out of the three gpu makers I believe.
