I am using kdenlive since one month and I am facing a strange problem when rendering my video.
Sometimes the rendering operation seems to end correctly but the generated file is broken or sometimes the computer crashed before the end.
My movie is 5 minutes long which includes titles, movies and pictures with a lot of different extensions (.mts, .mov, .mpg, .mod, .wma, .flv, .png, .wma, .jpg, .mp4, .avi, .m4v, .wmv). I read a lot of forums on these problems, I tried to use kdenlive in root, I tried to avoid to use titles and I replace by Jpeg, I tried to avoid to use the 2 passes options. But I didn't fix the problem.
My melt version is 0.7.7 with Qt: 4.8.1, KDE platform 4.8;5 (4.8.5) and kdenlive 0.8.2.1.
Linux version: 3.2.0-38-generic (buildd@akateko) (gcc version 4.6.3 (Ubuntu/linaro 4.6.3 -1 ubuntu5)) #61 ubuntu
Please if you have any ideas ....
