When I use Windows and install Kdenlive, Kdenlive detects my GPU. But when i m using Zorin OS or any other distro, I can't see this. Only "VAAPI". Any idea or solution for this?
Are you using flatpak? If so use the .deb instead or you could try tweak the flatpak with flatseal.
I usually use flatpak versions of programs. What can I do with flatseal?
With flatseal, you can set up Permissions for Flatpaks. When You have installed it, start it, and choose Kdenlive. And then You should see on the right Side a Toggle to allow Access to all Data.
Or You could use the AppImage instead the Flatpak Version, what You can download here:
Look for this:
I know that the appimage version of Kdenlive automatically recognizes the GPU on my computer with an nvidia card.
When You know that, You could use the AppImage.
I just turned on GPU acceleration on Flatseal.
