i need to batch a great many mpa files to mp2 files. i want to
keep everything about the files the same as the original mpa
files except i need to change the frame rate from 29.97fps to
25fps. could someone walk me through this? or point me to
the best way to do this?
fwiw, this is related to a thread in the virtualdub/virtualdubmod
forum called 'm2t problems.' i'm changing a lot of hdv m2t files
from 29.97fps to 25fps. this is being done by:
1. extracting the audio from the 29.97 m2t to a 29.97 mpa (dgindex)
2. processing the 29.97 m2t down to a 25fps m2v (ffmpeg/avisynth)
3. processing the 29.97 mpa down to a 25fps mp2 (belight)
4. recombining the 25fps m2v and mp2 files into a 25fps mpg (mplex)
so far, the snag in the process is the batching of the 29.97
mpa's down to 25fps mp2's with belight. belight seems to be
having a continuing and long term problem with its batch
functionality (just skimmed the belight release thread and
there are lots of references to this problem).
