No audio with Avisynth?

[xaanin]

Hello, I'm trying to speed up a NTSC Film avi to PAL (23.997 to 25 fps), but my problem is that I don't get any sound. I've also tried ripping the sound and using audiodub to use a separate audio source, but that won't work either.

I'm running Windows XP on a T-bird 900, 384 ram and 7200rpm HD.

Some more details are necessary.
Is the audio uncompressed?
Post the .avs here.
Which encoder do you use?
What are you aiming for, .avi or .mpg?

Audio is compressed in mp3 format when using the avi audio. When trying with a separate audio file then no, the audio is not compressed.

I've tried this script with both Virtualdub to produce another avi, and with tmpgenc, and neither will give me a file with any sound. If I try using the audiodub I get an error saying it needs a separate video and audio input...

I'm aiming for a .mpg

OK, I reduce it to its essence, correct me if I am wrong.

AVISource("510_How_To_Eat_With_Your_Butt.avi")
assumeFPS(25,sync_audio=true)

Decompress the audio with VirtualDub and save it as new .avi, that you as AVISource. That might solve the problem.
If you use the AudioDub command, you have to define a seperate WAVSource.

video = AVISource("510_How_To_Eat_With_Your_Butt.avi")
audio = WAVSource("................wav")
assumeFPS(25,sync_audio=true)
AudioDub(video,audio)
#using this script you might end with sync problems, not sure.

Btw, are sure "assumeFPS" is that, what you want? It will speed up. To preserve the playback speed try "ChangeFPS".

#4 NTSC film 23.976 -> PAL 25

That's why I believe assumeFPS should be used.

Also I got it working, I had to make a copy of the avi without any sound to be able to use a .wav audio source, thought it would work with the original avi and a stripped wav but apparently not.

Thanks for your help
