here is my new short film (23 minutes):
Edited with Kdenlive 9.6 on Ubuntu 12.04 (64-bit)
Nearly no crashes. As recommended, you need always about 20 GB free disk-space.
Kdenlive is still my favorite, much easier to work with as with lightworks. Even lightworks maybe has a better trim function.
Filmed on Canon 600D with Magic Lantern 2.3
Hope you like it.
