You may be right that the input frame rate does make a difference (and
that MEncoder only supports 24000/1001 -> 30000/1001 muxing, I don't
remember), in this case it may not make a difference and you can use
FFmpeg which will simply repeat the frames as necessary, no
additional calculations needed.

You can overwrite the input frame rate with "-r" if this is your question.
