convert 23.976 and 29.97 to 25FPS

How can I convert AC3 audio

from 23.976 and 29.76 to 25FPS for PAL

i.e.

1) from 23.976 to 25
2) from 29.76 to 25

USING BESWEET

??

Actually both conversions are the same, because when 29,97fps is converted to PAL, the video is first converted to 23,976fps without speed change.

Sorry, I don't know anything about BeSweet, but does it have an option to increase audio speed? If yes, use that to increase audio speed with 4,096%.

Something like this

"BeSweet.exe" -core( -input "myfile.ac3" -output "mynewfile.ac3" -logfile "log.txt" ) -ac3enc( -b 384 -6ch ) -ota( -r 23976 25000 )

thanks a lot

but what about audio 29.97 FPS ?

I made a search in Google and found this :

-ota( -r 960 1001 -G max )

For audio NTSC , but what does it mean ???? can I use this as generic NTSC to PAL Audio 25FPS conversion ??????

Just use

"BeSweet.exe" -core( -input "myfile.ac3" -output "mynewfile.ac3" -logfile "log.txt" ) -ac3enc( -b 384 -6ch ) -ota( -r 29976 25000 )

Heh, that would be a very stupid thing to do. Because when converting, the video is 4% sped up, but using that BeSweet command, the audio is slowed down 20%.

Like I said, just use the same command line for both conversions.

IMHO it depends on how you convert video. In case of 23.976 -> 25.000, you must speed up audio by 4.2708% and this conversion can be done by -ota( -r 23976 25000 ).

In case of 29.970 -> 25.000, you can either decimate video down to 23.976 and then speed up it as above, or directly slow down it to 25.000 (by 16.583%) (IMHO it is to distort movie unacceptably).
