I just came across this and found an easy option in the latest version of the help file. Compare it four yourself:
# Default preset listHandBrakeCLI --preset-list# Additionally load presets defined in the GUIHandBrakeCLI --preset-list --preset-import-guiIf you are asking youself:
Well, using the path to a specific file is also fine, isn't it?
If you want to keep track of every location on every system that you will ever use, sure! On Ubuntu I might have a package from a repository, Flatpak, Snap, eventually Appimage. I'm certain there are different styles to install and use Handbranke on Mac and Windows. Use --preset-import-gui, it's nice and simple.
