I snipped a bit from the quote above about 3:2 pulldown to 29.97 fps because it doesn't apply to the conversion we would want to do to watch a high def movie converted from MKV to WMV format on our Xbox 360s.

So basically, when I want to convert a PAL movie shot on film from 25fps to the correct 23.976fps, I first play the MKV to determine if the pitch has been corrected after speedup to PAL.  If the voices sound a little high pitched, then my movies.avs file contains:

QUOTE

DirectShowSource ("C:\WMV-HD Conversion\movie.mkv")
AssumeFPS(23.976, true)

If on that rare occasion the audio had been pitch corrected to compensate for the 4% speedup to PAL, I still want to correct the framerate, but also correct the pitch so that sound and dialog doesn't run too slow and low pitched after correcting the speed, in which case my movies.avs file contains:

QUOTE

DirectShowSource ("C:\WMV-HD Conversion\movie.mkv")
AssumeFPS(23.976, true)
TimeStretch(pitch = (100.0*25.0)/23.976)

Obviously, you'll have to change the path to where you keep the movie.mkv file you want to convert.

I just finished watching Mindhunters, a cool flick I never could have stood to watch with squeaky voices.  I converted it using this method and the speed and pitch was correct, the audio was never out of sync and the video was smooth as silk!
