And how do you do that using GUI? The exact same way, looking blindly and playing random videos (or name the file properly in the first place).
Thumbnails? Or maybe searching through find, which is not as straight forward as something like search in dolphin.
Also “name the file properly in the first place” is such an off putting mentality. I want my computer to simplify work by doing things for me, not need to properly catalog every random video because of the failures of my UI.
Name the file properly, say that to a photographer with 3 cameras and an auto export. This is what thumbs and a gui are built for.
