Comment:

 The relevant output would be the one of {{{ffmpeg -i output.mkv}}},
 FFmpeg's matroska muxer supports variable frame rate, so it is not
 necessary to actually write the duplicated frames to the output file.
 Please compare with a muxer that does not support vfr like {{{mov}}} or
 use {{{-vsync cfr}}} to force the actual frame duplication.
