[SoX-users] wav speed up to match inverse telecine

[Jim S. <jsh...@pp...>]

Friends,

i am in need a means to 'correct audio' for  video that has been inverse 
telecine.(ivtc)
basically i capure video at 29.97 - i can sucessfuly remove the 3 2 pull 
down making it the or (film) 24 fps ( 23.98 fps)
but now the audio is out of sync.

the video ( after some time like 10 min ) is ahead of the audio. I think 
this is because the ivtc basically throus away frames

My solution might be use sox and speed up a wav and mux that [ speed up 
]  sound with the video [ that has had IVTC applied }

something like
sox -V file.wav speedup.wav speed 1.1

has anyone ever done this - am i on the right track?
