My issue with Kdenlive is that no matter what I do it never uses my GPU (7900 XTX) for rendering. I've tried multiple rendering presets and configs, codecs, made sure all the libs and related packages are installed but it never works

I use the Flatpak and here's how to get VA-API working:

Run the following command: ls -lah /dev/dri/render* and note down the number behind renderD
Create a project
Go to Project -> Render
Select VAAPI AMD H264 and click Save current preset as new custom preset
In the new preset, replace renderD129 with the result of the command in step 1, e.g. renderD128

You should now be able to hardware encode with the custom preset. Since you have an 7900 XTX you can also use H265 and AV1 to encode. For that you can copy the preset again and replace h264_vaapi with av1_vaapi or hevc_vaapi. When using AV1, you also have to switch the audio codec to opus instead of aac.

I'm not using the flatpak but rather the one straight from Arch repos. I did notice all the presets I had were using renderD129 and I found out I only have renderD128 as well so I changed that, but now it barely uses my GPU and CPU during render.

❯ ls -hal /dev/dri/render*
crw-rw-rw- root render 0 B Sun Feb 23 09:47:45 2025  /dev/dri/renderD128

Here's the render settings and outputs of btop, amdgpu_top and LACT:

It feels basic but it gets the work done. As long as you don't need a complex array of effects and graphics, it fits. Most of simple amateur video needs are easily covered.

I've tried it a number of times, but never could stick with it due to how buggy it was, though the last time I tried it was about 3 or 4 years ago, so it might be in a better state today.
