Comment (by elenril):

 Are you entirely sure this worked as you wanted? I see no indication that
 -fpsmax was ever intended to work with VFR. As per the manpage:
  -fpsmax[:stream_specifier] fps (output,per-stream)
    Set maximum frame rate (Hz value, fraction or abbreviation).

    Clamps output frame rate when output framerate is auto-set and is
 higher than this value. Useful in batch processing or when input framerate
 is wrongly detected as very high.  It cannot be set together with "-r". It
 is ignored during streamcopy.

 In other words, it affects the way the output framerate is selected, but
 there still is a fixed output framerate.
