Premiere Pro does not use GPU even renderer is set to Cuda

Report · Mar 07, 2023

Hello, I am Frans from Indonesia.

I have been using Pr 2020 for editing video 1920x1080p 30 fps for several days. Sadly, for 17 minutes of video, it took 7 hours 45 minutes of exporting. I know it is NOT normal, i know. I know you are also curious about my specs.

Here it is :

- Asus TUF gaming FX505DD

- Ryzen 5 3550H (constant full load to 100%)

- IGP Radeon Vega 8 (working up to 30% something, then constant to 10% something)

- dedicated GTX 1050 (extremely rare working up to only 40% for seconds)

- Ram 8+4 (constant load 11,8gb)

- nvme ssd for system + hdd for storage

FAQ :

1. Have i set the renderer to CUDA? I have.

2. Have i set the encoding to hardware encoding? I have.

3. Have i used any other apps to show if my GPU works? I have. Blender using BMW, render spent 7m59s. Games (Naruto storm 4 and eFootball PES), GPU works up to 90-100%.

not normal right?

I have tried using version of Pr from 2017, 2019, 2020, 2021. The results are variative, but still hours.

But there is something i realized recently. When i see rendering process using Media Encoder (Me) 2020, at track that is using text, the GPU works to 40% as i mentioned above. At track that is using keyframe to edit position and scale, the GPU is back to 0%.

My concern questions are :

1. Is there any possibility of software issue? or it is just my GPU?

2. Is it normal, when the track is using text, it needs more of GPU to work, and when the track is using keyframe to edit position and scale, it does not need GPU to work?

Enabling Mercury GPU Acceleration is for accelerated timeline playback, not for encoding. Most encoding and transcoding happens on the CPU, but the latest versions of Premiere have GPU-accelerated H.264 encoding, which would use your GPU, if it's supported. I believe Premiere 2020 was the version that added this feature, so what options are you exporting with? Can you please post a screenshot of your entire Export Settings dialog with the "Video" tab selected and expanded?

One thing to ask yourself:

How much VRAM does your particular GTX 1050 have? Some of them have only 2 GB total of VRAM, and if that were to be the case, then it would not surprise me that the hardware acceleration would cut out in the middle of the rendering job due to the depletion of the GPU's VRAM.
