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? |
