Question

GPU Works in Premiere, doesn't work in After Effects during export

Hello.

I made a simple test. I took a footage 1280*720, placed it in Premiere project, changed scale to 300% and rendered it 3840*2160 through Media Encoder. My GTX 1060 was loaded 30%. Video engine load 0%. Then I did the same in After Effects. GPU load was 0%, Video engine load 0%, time of rendering 2 times higher. What is the problem? Adobe software 2018, windows 10 64, latest drivers, have no IQSV in my CPU. Cuda was enabled in AE, PP and ME.

      Hi сергейз48634810,

      Thanks for posting in Adobe Forums. As we know After Effects & Premiere Pro are applications designed for different functions & they take the advantage of GPU on your graphics card for different kinds of processing. We cannot compare both the applications in any way including the speed & performance. Please check the following article for information related to the GPU utilization in AfterEffects:

      Thanks,

      Vidya.

      Hi Vidya,

      Thank you for your answer. I've already read this artice, it's not very helpful. I'd like to use more GPU power in classic 3d. Now I see that my GPU uses cuda for making a preview but it doesn't use video engine hardware decoding for that. How can I turn on video engine inside AE?

      Also I see that when exporting h.264 from AE through ME my GPU doesn't work for scaling and it doesn't work for encoding. It's very frustrating, is there anything I can do to fix that?

      Hi сергейз48634810,

      You can enable in AfterEffects, File > Project Settings > Video Rendering & Effects > Use "Mercury GPU Acceleration".

      In Media Encoder, in Queue panel, right bottom corner, Renderer > Select Mercury GPU Acceleration.

      Please note, AfterEffects do not use GPU for all functions.

      Thanks,

      Vidya.
