Audio Sync Out (even using Virtual Dub)

[Bertold]

Im not quite a newbie at this but still learning.

I have some DIVX rips which after ripping the sound with vrtual dub and converting to mpg with TMPGenc the audio sysnc is out on the MPG.

I have searched the forum and every one with this problem seems to have solved it by using Virtualdub but it doesn't seem to work or only have the problem after its been converted to a VCD.

As I said i do know what im doing to an extent most conversions work fine but i do have a few dvd rips which i just cannot get to work.

Anyone got any suggestions.

Try use avi2wav or goldwave to extract the audio to wav instead of virtualdub and see how it works.

Thanks for the advice i tried them but that didnt work.

Under environment settings will the order of the files in the VFAPI Plug ins make a difference. if so what order do they need to be in.

Otherwise any other ideas please

The audio is out of sync you say but in what way. Is out of sync the same amount from the start, does it gradually get more out of sync as the movie plays or is it apparently random. Which one of these it is will help us to pinpoint the problem and maybe find a solution.

BTW, if it is gradual sync loss, this is commonly caused by encoding the mpeg with a different frame rate from the original avi.

you may not have done it right with vdub
open avi in vdub go to audio check full processing mode
then go to audio again andcheck conversion then check 44100/16bit/stereo/highquality then save the wave or avi but use video/directstream copy if you save the avi. this should solve your problem

The mpg sound creaps out of sync to as much as 20 seconds towards the end of a film.

I have tried all the suggestions above which didnt work I have managed to solve the problem its long winded and involves converting twice.
I welcome any other ideas to speed this up

This is how i have done it.

Start a new project in tmpgenc load the video & audio then start decoding (dont choose a template).

The mpeg file should now be in sync but i haven't found any software that will burn this to vcd so you have to then convert this file using a template result a working mpg in sync that you can burn to a VCD.

I dont know why this works as i am still learning how to use tmpgenc but it worked for me !

If it is gradual sync loss as you describe the most likley cause is that when you encode to VCD you are using a template or setting where the framerate does not match that of the original avi. I would check this.
