Hi

I've a problem of conversion.
I've a Mpeg2 video with 29.97 Fps NTSC and its audio stream Ac3 , no problem at all.

But i've another Ac3 stream, which is at 23.976 fps ( part of a divx) and I want to multiplex it with Mpeg2 video ( I'm using Maestro).

I'm often using Besweet to convert Ac3 23,976 to 25 fps without any problem at all !! But this time, when I use besweet to convert 23.976 to 29.97 fps, sound is totally accelerated !!!! Voice, music, is played quickly than normal ...

How can I make a proper conversion of this 23.976 fps ac3 stream to 29.97 to have a proper sync in DVDMaestro ?

Thanks a lot
Bye

What you need to do is telecine the video to 29.97 fps, not change the audio. You can use DoPulldown from the doom9 download page to do this. See this tutorial (http://www.doom9.org/ivtc-tut.htm) for more info on framerates and DVDs.

who the hell did introduce the 29,97 fps - thing into Besweet?
I don't know why someone should ever use a 23,976 -> 29,97 / 25 -> 29,97 or vice versa conversion!

Could 29,97fps be taken out in one of the next releases of the besweet (GUI) ?

It is useless and confusing.
