Hi,
I read many posts on this forum in Media Encoder CPU usage (50% instead of 100% for exemple), but I never read about optimisation.
So, I got two questions :
Tell me if you need more informations
Thanks !

I made some render test on different servers.
For a 3 minutes video with 2 quick fast-forward and contrast / level / luminosity filters.
On server with 18 CPU Cores :
- render with After Effects (through x264 encoder) : 18 min
- render with Media Encoder Youtube 1080 preset : 25 min
On server with 8 CPU Cores :
- render with After Effects (through x264 encoder) : 19min40
- render with Media Encoder Youtube 1080 preset : 28min30
On server with 4 CPU Cores :
- render with After Effects (through x264 encoder) : 20min20
- render with Media Encoder Youtube 1080 preset : 44min
CPU usage during tests :
- 18 CPU : all cores at ~18%
- 8 CPU : all cores at ~30%
- 4 CPU : all cores at ~55%
My question : how can I improve render time ?
Thanks

We just tested a transcode from Phantom4 Pro 4k H264 to Cineform 4k on 3 different machines in the office. 4790k 4c/8t 4ghz was the fastest. 8c/16t 3.6ghz Ryzen 1800x next fastest. Xeon 24c/56t 2.2ghz slowest. What?! How do we get AME (Adobe Media Encoder) to use all available resources so we can offload transcoding to the most powerful machine? We are looking to invest in a dual AMD 7401 server for 3D rendering and I was hoping to use it to transcode also. With 96 threads it should blow through this, but our finding is that AME prefers clock speed over cores. Any thoughts or help appreciated. Willing to use alternative software as long as we can still use Cineform.
Interestingly, on the 56 thread machine, the cpu usage on the shamefully low 12 threads it was using, was only about 30% utilization.

Did you find a solution for this, I’m just looking at this exact problem rendering out 4K footage and getting different opinions on what to buy? I have been looking at a Z840 36core machine for rendering but your saying this isn’t the best option?

Unfortunately there is no "solution". After much testing and reading, it turns out AME pretty much maxes out at 6 cores 12 threads. The perfect CPU for this right now is the 8700k since it has the fastest core clock speeds. We ended up getting the i9-7940x as our editing workstation because it supports 128gb ram which we frequently use in after effects and 3D rendering as part of our pipeline. Check out Puget systems' articles for a very in depth comparison of adobe suite vs each CPU. Disappointing from Adobe's part in my opinion. There's no reason in today's landscape of CPU cores that we shouldn't be using all that available horsepower. Again, I can't recommend any CPU above 6 cores/12 threads for adobe workload. The faster the CPU clock, the better your experience will be.

ADOBE - PLEASE FIX THIS! I have to stop all other work to use AME. I can select max processors in AE, why not in AME??
