Does the videos were shot in one piece or in successive scenes?

Not sure whether this is the same problem, but I experienced similar
symptoms with a VOB file (from a DVD camcorder) which was having
timecode breaks. I've traced down the problem into FFmpeg. MLT request
the AVFormatContext->duration in src/modules/avformat/producer_avformat.c:producer_open()
and in fact, libavformat returns the length of the *last* scene.
So I had to trick kdenlive by "reseting" timecodes of the input file
using ffmpeg with -acodec copy -vcodec copy -dts_delta_threshold.
There surely must be a better way.
