View Full Version : BeSweet / BeLight: NTSC IVTC to PAL audio not correct?

I need to do a standards conversion from NTSC to PAL.

My source material is an NTSC Digi-Beta with 3:2 pulldown, which I have captured as an uncompressed AVI and WAV File. The AVI has a runtime of 22:19

I've then used the following AVISynth script to IVTC, resize and change the framerate before encoding with Cinemacraft:


AVISource("E:\DR Output Media\WTC_JAP_NTSC_TEST\43P_WTC_JPN_01.avi")
AssumeBFF()
Telecide(guide=1)
Decimate()
Lanczos4Resize(720,576)
AssumeFPS(25)


The resulting MPEG-2 file has a running time of 21:24:00 in DVDMaestro, which by my calculations makes a speed up of 104.283489% which sounds about right.

I've then run the WAV file through BeSweet, using the following command line.


BeSweet.exe -core( -input "E:\input.wav" -output "E:\output.wav" -2ch ) -soundtouch( -r 23.976 25.000 )


But this WAV file comes in a 22:18:22 in Maestro. When I convert it to AC3 using Sonic's AC3 Transcoder, the runtime is 22:17:15.

ANy suggestions where I've gone wrong? I'm guessing with the audio hence my posting here...

I hope the values are:
22:19.00 -> 21:24.00 video
22:19.00 -> 22:18.22 wav audio

Try with integer values: -soundtouch( -r 23976 25000 )

When I convert it to AC3 using Sonic's AC3 Transcoder, the runtime is 22:17:15.
22:18.22 wav audio -> 22:17.15 ac3 audio

Really strange, if is true your encoder seems broken.
