Audio gradually getting more and more out of synch

[wiggy]

Hi to everybody

I'm not a complete newbie in regards to converting avi and such like to vcd/dvd/etc but when things don't go completely right then I'm stumped. Most of the avi files I converted to dvd etc have worked just fine using Nero or Roxio but one or two seem to lose audio synch during the conversion. It isn't by a fixed amount (which I understand how to correct) but the audio gradually falls behind the video as the film progresses and gets worse as you go through the movie. Can anyone advise me of a reasonably simple way of correcting this or point me in the direction of where I might find the answer.

Cheers

this usually works:

download Virtualdub (free)

http://www.videohelp.com/tools?tool=Virtualdub

change the audio to a .WAV file using Virtualdub. Load the file. Go to "video">Direct stream copy. Under "audio">full processing mode, Click "audio" again. click Conversion check 48,000Hz and check "high quality" and ok. Go to "audio" >compression, select "no compression" (PCM) and ok. Finally go to FILE> save WAV. this will produce a .wav file (audio only).


when its done, load the original avi file again under file. go under audio, select full processing mode, go to audio again, select wav audio. load the wav file you made earler.

under video select direct stream copy, again under video select framerate and change so audio and video durations match.

go to file and save with a new name and see how it is.

Many thanks for the advice - I'll give it a try and see how it goes.

All the best

if it still isn't good, post everything you see under file>file information when the ORIGINAL file is loaded in vdub
