MP 7,1 Editing 1080p not smoothing FCPX with 12 cores and 580x [video example]

[jccmaxon]

Hello,

I have got a new Mac Pro. 12 cores and 580x. When I playback sometimes lag. My videos are 1080p mp4. What hardware would have to improve? With my iMac 2013 late I could do it smoothing. I don't understand. The CPU usage is 6% and the GPU memory over 80%, but it reaches 97% fast. I don't want to use proxy with a new Mac Pro.

If I buy a 5700xt or radeon vii: will it be smoothing while I playback? Because I suppose CPU It isn't the problem.

Thanks

Please help. I need more power To playback

The most likely reason your iMac is better is because it has the integrated GPU.

Playback speed also depends on how many layer of effects and adjustment you have used. Realtime Preview could become choppy. It is hard to say what the reason could be, if you don't share the parameters.

What computer is it: Do you mean the 2019, current Mac Pro?

Yes. New Mac Pro 2019. 12 cores 580x. Import vídeos 1080p60 mp4

Here You can see it all

This happens in 1080p. I would like to pass at 4k soon. What should I improve? I guess the GPU. What is your opinion? Thank you

Radeon VII is best deal

 

[pertusis1]

What hard drive is your video stored on?

 

[bsbeamer]

What OS is/was your iMac running?
How much RAM was in your iMac?
Which dGPU was in your iMac?

How much RAM do you have in your Mac Pro?
Are you using internal SSDs for your media/scratch drives? If not, what is the config?

Have you run AJA System Test Lite and/or Blackmagic Disk Speed Test to confirm data rates are not an issue?

Have you tried to see if hardware acceleration was working in iMac vs. not working in Mac Pro? Many use VideoProc to test. The Mac Pro's CPU (Xeon) itself does not work with H264 as well as iMac (Core i3/i5/i9) due to lack of Quick Sync in (most) Xeon processors.

This is s good option?

250mb/s RAID hdd, but I also tried with the internal nvme, the same. Hard disk not

thanks

XFX GPUs have known issues with macOS and are NOT recommended over other manufacturers. That is the reason Sonnet will not certify ANY XFX GPU for use with their eGPUs in macOS. See page 7:

imac 27 late2013 i7 and 780m. No problem with the same external disk wd Thunderbolt duo 6TB.

No dgpu in IMac.

24gb ram with the iMac and now 32gb.

using internal SSDs the same problem. Disk no problem.

new Mac Pro is more power than last iMac. I thougt it will be better. I dont understand.

If i buy radeon vii will it go smooth? Or is the problem xeon?

The problem occurs in transitions and when several videos are gathered on screen as seen in the previous video. the strange thing is that the cpu goes to 5% and the GPU also occurs when there is free memory. It will be the speed of the gpu. Will I need another gpu to gain fluency?

I don't think a Mac Pro can't get smooth playback

My iMac 27 late 2013 i7 and 780m. Mac Pro 2019 12 cores and 580 have To be better no?

 

[bsbeamer]

No dgpu in IMac.

That is incorrect. If you had a 780M, that is the dGPU.

I looked at that chart and I can't figure out where you are getting your info about XFX and eGPU's.

I have two XFX Radeon VII's. There may be problems that I am not noticing, but they work.

PAGE 7.

Not a single XFX GPU is listed as MAC compatible. First column would have an M/W for Mac/Windows. All XFX are W only, aka Windows only. Then look at a vendor like Sapphire who nearly all their GPUs with Mac drivers are Mac compatible.

Again, these are for eGPU but the same applies to macOS across the board. It is an excellent reference for all Mac-based GPUs.

 

[electonic]

The 580x should be more than enough for this. Your GPU is not the problem.

Do you have an old USB device or hub plugged in. USB is the pits when it misbehaves, creating lots of annoying interrupts.

 

[krakman]

your time line has row of little white dots along the top of it. this means its not rendered and its trying to render all the effects on playback.

you can try:

alt + shift + R to render all and see if playback is better.

or

in the viewer window click on view and look for "Quality" and select "Batter Performance" this will playback faster but with lower resolution. This does not affect the exported file.

TBH, the 7,1 is too new, you better contact Apple. There is not much the community knows about the 7,1.

https://www.sonnettech.com/support/downloads/manuals/Compatibility_Graphics_Cards.pdf

All Radeon VII are the same. Only reference card available, no 3rd party options, brand won't affect compatibility.

Anyway, I am running a XFX Radeon VII with macOS right now.

 

[bsbeamer]

Did you import your apps and settings when setting up MacPro, or was it clean and you installed FCPX?
What version of FCPX and is there an update available? There was a special update for MacPro issued.

What exact macOS version on MacPro? About This Mac > Software > System Software Overview. Copy/paste those details.

High Sierra and Mojave have better GPU performance than Catalina in all testing to date, but that is not your issue here. Unfortunately you cannot roll back your MacPro and it requires 10.15+ to function.

Your drive speeds look slow. Even single SATA SSD would have 400-500MB/s speeds via most USB-C connections. That may be playing a role here, but likely not the root cause.

Please read that Note 2 carefully, same for all Radeon VII regardless brand.

Some further questions: what codec is the footage? All H.264? It looks like the clip you did Get Info on in the Finder is H.264. If so, the T2 chip in the Mac Pro *ought* to be handling that decoding on the fly. However, I also noticed the dimensions are only "16 x 9", which is an aspect ratio, not a set of dimensions (like 1920 x 1080). So that's a little odd. I'm just wondering if there's some sort of mismatch or something FCPX doesn't like about that base track. Still, that wouldn't explain why a 12-core Mac Pro is getting tripped up where a 2013 iMac is not...

Do you have any effects or filters applied to the main track? That would compound the work that FCPX is having to do, along w/ the compositing of layers. Again, I wouldn't get why a 2013 iMac would do a better job if all else is equal.

After the first clip, when you start adding layers, I notice the timeline is un-rendered (dots at the top of the timeline window). Any chance the iMac has been previously given the "opportunity" to render everything in the background, so that it DOES play back smoothly where the Mac Pro does not? Might wanna check the background render settings on both setups.

 

[h9826790]

your time line has row of little white dots along the top of it. this means its not rendered and its trying to render all the effects on playback.

I think this is exactly what OP want. No need to wait for rendering.

 

[fhturner]

I think this is exactly what OP want. No need to wait for rendering.

Right, but it might explain at least why there's a perceived degradation in performance between the Mac Pro and much older iMac if the latter is rendering in the background while the former is not.

XFX cards ACROSS THE BOARD have compatibility issues with macOS. It's been well reported in this forum and many others. Radeon VII may be a different case (no manufacturer versions) but still would not recommend an XFX version over any other for macOS specific usage. As always, some people (yourself included) get XFX cards to work and others run into major issues.

Radeon VII has other issues and would personally not recommend using that particular GPU, especially if you're trying to troubleshoot an issue. The stock 580X config is where I'd start...
