Hello,

After mixing a few clips, I tried to output the resulting video (different codec : mp4, xvi, mpg2,...) but nothing was in the file. I checked by doing "melt myproject.kdenlive" in a terminal. The result was a window with "INVALID" text displayed. In the terminal, I have the following errors :

Thanks for you help.

I found what was the problem: I had melt4 instead of melt5.
