I use video editing private quite a lot, changed from the better Kdenlive to Pinaccle (Windows) but get tiered of the bad performance of windows pinnacle.
I thried installing kdenlive via software - comes from package hub I thing. Installation work well, but Kdenlive do not start.

hans-christoph@LINUXSLES:~> kdenlive
