@herr_irrtum @lightweight @Salty @trib @meejah @jdmcg particularly with video editing, yes kdenlive for example is great, easy to use, you can make a video with it (especially if it's not such a complex project or you don't have to do too much colour work or effects).
But kdenlive has it's limitations, also how it uses the hardware, so that for us for our current project it's not good enough. And there is no open source video editor that is.
In a learning setting I would agree that learning video editing with something open source like kdenlive could make sense. And for people who really want to work with it the option to then learn with something more powerful like davinci resolve or any of the others.
