From my expirience: kdenlive kinda works but is very basic, yet quite complicated to use, Openshot and Pitivi are similar but crash a lot more often. With that said, blender is pretty much completely missing the audio parts. Want to add some compression and gating to your audio track (and yes, you do),? Nope won’t work. Gotta fire up ardour and xjadeo for that.
