I did not want to post a working command line but an as-simple-as-possible
command line that allows to reproduce the problem (and avoids using an
external library). Note that I missed the issue originally because of the
noisy x264 output.
The FFmpeg mov muxer only supports cfr, if your input file is vfr, frames
are dropped and / or duplicated to produce cfr output. Knowing the correct
frame-rate is not always easy.
