Adobe Premiere Pro not utilising CPU or GPU

[Chris Houston]

Hi There,

I have a reasonably recent Ryzen build for video editing. My issue is that in Adobe Permiere Pro will only utilise around 30% max but generally sits around 20% on the CPU and no more than 3% on the GPU while encoding 4k footage with 2 LUTs, warp stabiliser and grain applied.

My build:
Ryzen 1800x @ 3.9 GHz with Noctua DH-14
GA-AX370 Gaming 7
32 gb GSkill Flare X (2400 MHz) at 3010 MHz
GTX 1080 Ti
Samsung 950 Pro 512 gb (OS Drive)
2Tb Firecuda
Corsair AX760
Windows 10 Pro

I have CUDA enabled in premiere pro. All other settings are standard.

Any help much appreciated.

Cheers,
Chris

Hi. I have read in past threads that Adobe is quite selective with using hardware for its acceleration. This is especially valid for the GPUs but should get frequently updated by Adobe. I assume its the same issue with your Ryzen...Adobe needs to work on this.

For your reference: https://helpx.adobe.com/premiere-pro/system-requirements.html

If I was you I would raise this topic to the Adobe product support and ask for their advise.

Adobe only uses the GPU for preview playback. Final render is CPU only expect for a few things offloaded to GPU for motion blur and minor other things. Seems like its Encoder is waiting on something since the CPU is only 30% load.

Well that's how far you will get https://www.pugetsystems.com/labs/articles/Adobe-Premiere-Pro-CC-2015-Multi-Core-Performance-Update1-806/
you can try updating to newer, I know they make it use more cores currently, still it depends on what you use.

Is it worth turning off CUDA and forcing software only?

Worth a try for sure. Would expect that then GPU usage reduces and CPU increases.

there is something not right... I am currently exporting a 1 minute clip as a test which is a mixture of 4k and 1080p slow motion footage. In software rendering was fast, about 5 minutes to render all effects. The encode is currently sitting at 2 hours!!! this is slower than my last CPU which was an ancient Intel 2600k.

Based on this review: http://www.guru3d.com/articles_pages/intel_sandy_bridge_core_i7_2600kthe_2018_review_time_for_an_upgrade,12.html

The Ryzen should be at least twice as fast!
