I edited my blender reel for the Che!Blender conference using KDEnlive.
I could have used Blender, but I wanted to try with KDEnlive just to know.
The result was pretty good. Despite some glitches in some advanced features (speed control previews fine but renders bad and some weirdness in the UI of the overlay filter), it worked great with good performance and better stability than previous versions.
The overall UI is neat, although it's clearly something that needs further improvements.
