Same, having an issue that the rendering is slow when trying to use hardware encoding.
Running a 7800X3D and a 7900XTX.
I’m rendering a 1080p@60FPS video with av1_vaapi (hevc_vaapi was even slower) and it’s between 70-80FPS while encoding.
(encoding,parallel) = (16,8) and that yielded the most results. I tried 16/16 but no change.
CPU is at around 38% while GPU is at around 10%:
Might help if I post about my environment?
My host system is Fedora Kinoite and I’m running kdenlive inside of an archlinux container via distrobox.
