My bad, I realized my comment reads a lot differently than what I was trying to say. Linux mints release schedule is not bound to Ubuntu. Linux mint gets a new major version every two years (although this is not strictly set) while LMDE usually gets a new major update with the new Debian version, but because Debian has been around for a lot longer than LMDE the number is higher.
In my experience no, apart from blender integration kdenlive does everything it does and more and kdenlive gets more new features. I just wish there weren’t 10 different Foss video editors that don’t come close to the proprietary ones instead of focusing on 2-3 projects, but that’s for the devs to decide
