Top Spec computer But Premiere Pro running slow

Good morning,

I have:

1 - 18 Core (i9) @3,10 Ghz

2 - Nvidia GeForce CTX 1080

3 - 32 Gb Ram

4 - SSD disk

I tried

1 - Enable GPU Previewing

2 - Media Cache to Different Drive (SSD)

3 - only running AE at the same time

and yet - it drops frame as I play back, task monitor shows that it uses 10 to 15 % of the CPU, Ram is also partially use.

It does not go much faster than my MAcbook pro 2015.

Any tips welcome, I hope this could help others with a similar issue.

Thanks for your help

Something I often recommend is a proper internal hard drive setup. The following offers both excellent speed and organization. It's a good starting point.

C: Windows & Programs only

D: Project files, audio files, stills

E: Cache & Scratch

F: Camera media and proxies only

G: Exports

C, D and E can be SSD's, but F and G will need the most room, so large terabyte HDD's are probably the better choice.

Hello Jim,

your proposed set-up seem ideal, it would certainly be faster.

however:

1 - it would be harder to take with me to work on my MacBook when I am not home.

2 - I am afraid that dividing the project across different disk would be a problem with medi unlinked as I archive the project and work on it again months later as the client as for another video.

But from a pure performance point of view, your set-up seem ideal.

Thanks for taking time to answer,

Jessie

Hi Jessie,

Jim's suggestion is great, but heavy on the pocket. Also you can consider the following which is exactly what I do, to have great editing experience and staying mobile.

1- SSD for OS and Software

2- SSD for exports, cache and some personal files.

3- RAID0 HDD (WD black 2x 2tb) for Media and Projects.

4- External SSD for proxies. This way when you can grab the external and edit using proxies on your laptop on the go. I work with 2 fail proof systems: a) Set up a one way mirroring/sync that only constantly copies folder structure, projects and other assets like audio or graphics to the external WITHOUT the original media. Size of proxies is small to save on space. b) I also rely on Adobe'c CC folder to keep my projects synced between my PC and my laptop. This way, when I need to edit on the go, I just grab my external, plug it into my laptop and launch the project, PP will ask to locate files, I hit cancel (not offline) and it locates the proxies and everything else thus allowing me to work on the go. Project is already synced with my PC, use teamviewer to export and upload.

As for your GPU, it is a great GPU, don't get me wrong, but I wont be surprised if it drops some frames on heavy 10bit 4k.

If you need further explanation about my workflow, please let me know.

Hello,

Can you share details about the project and media?

Are you working in 4k? Long GOP source media? 10bit?

You mentioned AE - Are you using Dynamic Link? Is this where the slowdown occurs?

Any 3rd party effects or filters?

I would imagine that some formats play back fine on that computer?

Hi Wes,

I usually use 4k footage and 1080p at 120fps 100m 10bit (from Sony A7Riii and S7s2)

AE = I use Dynamic Link (DL) a lot, cuz I love how much I can do within AE and bring it up automatically in Pr. that is really cool.

(that makes me think of another question, when I use DL I always must names them 2 times

1 - in premiere in my project panels

2 - in AE

the name does not seem to carry over. (just a detail but I was wondering)

I rarely use third party effects, I do however color grade, but only once I am finish with the project.

the slowdown occurs before.

I was hoping that a faster computer would help playback quicker, but I should also take in consideration that files format are more and more demanding to decode.

Thanks for your help,

Jessie

If you only have 1 SSD where everything is stored, that's your problem and a major bottleneck.

You need to have OS + Software on the main SSD, Media and Projects a separate drive (Preferably a RAID0) and Cache + Export on a secondary SSD.

Hello Chrisitian,

Thanks for the advice.

on both Macbook Pro (4cores i7) and PC (18 cores i9)

1 - I have software install on the Desktop SSD. (only OS + main software

2 - I have a USB3 SSD on which I save Footage + proxies and other assets (I tested the transfer speed, it copies at 400mb/s)

Hopefully it is sufficient.

On the PC the HDD copy at 200mb/s so the fact that it is external should not be the issue. (but maybe)

the point is that I take the project with me to work on my mac (when I am on the go) and on my PC when I am home.

Hey Jessie,

1 - I have software install on the Desktop SSD. (only OS + main software

What about the Cache? where is it stored? I think it helps if it is not stored on the main SSD.

2 - I have a USB3 SSD on which I save Footage + proxies and other assets (I tested the transfer speed, it copies at 400mb/s)
Hopefully it is sufficient.

I am not sure how you are getting these numbers, but I suggest you get Blackmagic's Disk speed test to know your writing and reading speeds of the drive. Nonetheless, assuming that it is 400 for both reading and writing, which seems logical for any SSD on a USB 3, Although it is enough to edit without major problems, you will still have some dropped frames on the playback for 10bit footage. And the same time, your 1080 GPU is not the best to seamlessly read those heavy files.

However, you should not be facing any problems with your proxies, if you are, please consider another settings for your proxies, or even create your own.

Lastly, your PC's performance is always measured by it's weakest link. In other words, it's only as powerful as the weakest component. In this case, your GPU and your storage configuration, not your CPU or RAM. To be more precise, Your CPU is 10/10, your GPU is a 7/10 and your storage configuration is a 6/10. that makes your PC a 6/10.

Premiere Pro is not yet optimized for more than 10 cores. CPU speed is more important.

What type of media?

Try using proxies:

Hello Peru,

Thanks for your answer.

seem like that computer is an overkill, did not need that many CPUs.

I have made quick comparison with my mac in encoder.

The PC with 18 cores is much faster at ingesting and compressing my proxies.

Yes - I use Proxies - ProRes422 (I got in a habit to do that with my Mac Book) cuz he does not playback live with 120fps footage.

Thanks again for answering,

Jessie.
