Earlier quoted context omitted.
was a few months ago when you tried kdenlive before or after their recent major overhaul? Basically, did you use the older version that was the traditional sequential-numbers versioning or the newer date-based versioning? (note that lots of progress has happened in even just the last few months)
Dunno to be honest. I've become a bit cynical because for the last decade or so people have claimed that there are good FOSS editors, then when you try and use them they fall apart at the first opportunity. Blender's the only NLE I've found that's not comically flaky. It's possible Kdenlive really has improved though.
Like I said before it's good to see some actual competition in this space.
