Advice needed on PC workstation for 8K files in After Effects

[Walter Soyka]

[Chris Pettit] “Cant tell you how much I appreciate your responses to Davids questions Walter. Interesting to get all of your perspectives on current state of AE. Just bought a new machine and will be installing CC (reluctantly) so appreciate all the info”

Thanks, Chris. I’d be happy to try to answer any other questions you might have.

Seconding what Chris said, Walter. Great info and very helpful.

A couple new questions:

What happens if we add Premiere Pro to the mix of applications?

We just got our first batch of test files back yesterday. They’re 2Kx2K previews of the 8K files. I did a quickie 12-layer comp test in Premiere (Chris, I think that was your suggestion, thanks) on my MacBook Pro and though it couldn’t playback in realtime, the rendered output worked great.

I’m thinking a 2K/8K proxy workflow in Premiere might be a good fit, especially since the masking tools in Pr CC are fine for our needs. I can also see benefits from dynamic linking between AE and Pr.

My understanding is Premiere takes advantage of GPU for final rendering so is this an argument for a fast CUDA-enabled GPU?

What about core count? Can Premiere take advantage of multiple cores/processors? We’re going with some flavor of dual Xeon, based on your and Chris’s feedback.

I assume maxing RAM and fast PCie storage is still the same.

Thanks again!

I’m going to add to this question as well (sorry to piggy-back David). Since Premiere is GPU accelerated ,as I understand it, can it take advantage of multiple GPU’s? (I will soon have dual Titan X cards) In Octane its all about CUDA cores, the more you have the faster the render. Is that true for Premiere?

Thanks again in advance Walter!

[David Lawrence] “My understanding is Premiere takes advantage of GPU for final rendering so is this an argument for a fast CUDA-enabled GPU?”

Yes. Not just final rendering, but normal playback, too.

Not everything happens on the GPU, but a lot of important processing does:

[David Lawrence] “What about core count? Can Premiere take advantage of multiple cores/processors?”

Yes. Totally different architecture than Ae in this regard.

Yes, with one caveat: real-time playback uses a single GPU only. Render supports multiple GPUs.

That article also links to this white paper, which I had never read before but does have some information pertinent to this thread:

Chris, on a separate topic entirely, I’d love to hear your thoughts on Octane sometime. I’m very intrigued, but I haven’t tried it yet. How much render improvement are you seeing? Could I build an Octane monster with as many GPUs as I could fit in the case, or an Octane render farm with a couple PCs and homogenous CPUs? How’s the workflow?

Great info, Walter. Thank you!

[Walter Soyka] ” I tend toward Xeon over i7 partially to be able to go dual-processor for CC 2014 multiprocessing, but mainly to support ridiculous piles of RAM. The i7 Dany lists above “only” supports 64 GB. An 8k square image needs 256 MB of RAM at 8 bits per channel, so holding 4 of them in memory consumes 1 GB of RAM! At 60 frames per second, every 64 GB of RAM in the machine will give you about 4.27 seconds of single-layer, full-resolution, in-memory storage. Even previewing at reduced resolutions, you will want all the RAM you can stuff in the box.”

The only downside of Xeons compared to i7’s is the clock-speed/price ratio. i7’s are unlocked and can be overclocked with limited impunity. My office X99 Haswell 5820 12 core is rated at 3.2GHz but runs with ease (<50 degrees) at 4GHz. Xeons are locked so you pay much more for equivalent cores and clock speed. That said, when I re-build my Premiere editing station it will be on dual xeons.

David – Is the reason you plan on choosing dual Xeon in the future because you want dual processors or more RAM than you can get with i7?

Hey Walter,

I’m coming into this thread really late (and butting into your question to Chris, sorry), but, have you seen the demonstrations of Octane using multiple GPUs? Note the viewport performance… unreal. The answer to both of your questions is yes. Ocatane will utilize as many Cuda cores as you can stuff into a case, and you can build a render farm for additional render nodes. BTW, it will also run on Amazon…

As I noted in another thread, one of the big advantages of Octane is the speed at which you can make design choices because of the viewport performance. I don’t think I mentioned how much faster the final gathering render is though. If you haven’t already, I think you should really download and try it for yourself… then try Arnold. I would be curious to know what you think. 🙂

More cores for Premiere.
