the audio prepass (frameno) is a very bad idea, imo. you really need
to use vf_harddup with mpeg output; otherwise if there are any
'duplicate frame' messages you'll have a broken mpeg file as output,
and broken a/v sync. and the frameno nonsense is incompatible with any
filters that affect frame dropping, which includes vf_harddup.
