running kdenlive 23.08.5 on Zorin-OS 18 i get a poor performance on generating proxy-files. There is a nvidia Quadro M4000 installed with nvidia-driver-580 an i think it’s working fine. glmark2 can use the GPU close up to 100% (checked with nvtop)
Importing a clip in kdenlive there is a max. utilisation of 12% while generating the proxy-file. “NVIDIA-Hardwareacceleration” is enabled and “Check Hardwareacceleration” shows “hardware encoders found and enabled (NVIDIA).”
The proxy-profile is set to “NVENC H264” . H264-codec is supported by Quadro M4000.
What’s getting wrong?
I’m using a X11-Desktop and tested with deb-Installation, Flatpak an appimage. All installations doesn’t use the GPU:
Hi and welcome.
Is there less than the 12% GPU usage before&after you are running proxy-clip renders? Meaning: Can you actually attribute this usage to the proxies being created? If so, then I would assume your GPU is properly used.
Remember, there are many factors at play and the GPU might need to wait for other things whilst rendering your clip. Not being 100% utilized doesn’t necessarily mean that it’s not working properly.
Yes, before and after rendering the CPU-Usage ist near 0%. I came from Debian12 and there i had much more power.
My Clips are 8 mins Full-HD and creating a proxy-file needs more than 1 minute. That’s nearly an PC with intergated intel-graphics.
That’s normal! The render will use your video card’s Nvenc; you should look at the “video encoder” graphic.
