or those files and ffmpeg, which appears you did not more directly
test. Recently on the kdenlive list, Evert was complaining about a
FFmpeg demux bug that causes this same issue with his AVCHD. When he
tried to do his own transcode using ffmpeg it reproduced the problem,
but using one of the DNxHD profiles we provide in Kdenlive, it
transcodes just fine.
