I have a problem with a title that has diffrent FPS for different parts of the movie

The first part is 24FPS (no problem there).
The second part is 25FPS (the problematic part).
The thired part is also 24FPS (also no problem here).

The problem is that you can't append a 24FPS to a 25FPS DivX files, so I converted the second part of the movie to 24FPS and I need a utility to sort of strech the sound file so it would fit the new length of the modified video file.

If anybody can offer help on the matter, I'd apprechiate it allot.

thanks

BeSweet is capable of doing ntsc2pal conversion.
you can find some info here (http://doom9.org/mpg/avi2svcd.htm#ntsc2pal).

Looks like this thing will do the job.

I'll try it tonight.

What I need is the other way around.

I see you have a NTSC2PAL mode and I need PAL2NTSC since I have a 25FPS movie that I need to append to two 24FPS segments.

Shure I can convert the two pieces of the 24FPS to PAL but I think thats kind of the wrong way to do things.

Thanks

What I ment when I saied:

The first part is 24FPS (no problem there).
The second part is 25FPS (the problematic part).
The thired part is also 24FPS (also no problem here).

Is that the whole movie was 25FPS but the two parts of the movie, the begining and the end, they total about 70 minutes, have a 2:2 PAL puldown, which Decomb succedded in deinterlacing very well and thats how I came up with the two parts of that have 24FPS.

In the middle of the movie there is a 20 minute part thats 25FPS and here the problem starts if the sound stayes in the same format, when I multiplex it back together its compleatly out of sync, but you probebly know that better then I do.

Hope you can help me.....

I saw in BeSweet Gui a feature called "Change frame rate from _____ to _____" in the Overall track adjustment, isn't this feature used for what I need ?

yes, but you should pay attention to line 10 at this thread (http://forum.doom9.org/showthread.php?s=&threadid=15738).

How is it possible to know which frame rate conversions are possible ??

Is there a more detailed version of the link you gave me in the replay above ?
