I'm trying to render my movie i made on Kdenlive, and it usually just says that render is done when it is already probably under 10%! When i try to play that video, it is unplayable. What is problem, i use Ubuntu 12.04 64-bit.
What version of Kdenlive and what version of MLT ?
Because there are some known issues like this with earlier versions eg 0.9.0 and 0.9.1 (from memory). 0.9.2 is recommended.
