Hello all,
using Kubuntu 18.04 LTS.
My old KDEnlive version (unkown excatly version may be 4.x, installed from apt) crashed (while starting) for a few days (i don't know why) and now i installed from snap the version 19.08.2.
KDEnlive started and runs fine, but rendering does'nt run really.
The Programm typing "waiting" but it's not create the destination file ("Rechnen.mp4") in the destination... and never ends.


Screenshots:





I hope anybody can help.

Cheers,
Ralf

Please try with the AppImage 19.12.1 from the download page. I assume you have some package issue as Kdenlive 19.04 onwards uses higher QT version as you have installed with Kubuntu 18.04 LTS.
