Questions asked many times however still not fixed....

I have the problem many other people have when you play a movie the video slows down and the sound keeps going and then the movie speeds itself up. Please dont tell me to seach around the forum because I have and in each one of those people tell that person to do that. So it is a big ol run around. I have posted this question 5+ times with no avail. Here is what I do, I open Jay and Silent bob.avi in virtual dub I get the vbr error so then I do the full prossesing mode and select no compression and then convert it to 44.1 khz and all of that then save. Just like I am suppose to do then I open it in tempgenc and put everything like it is suppose to be and save half of it and then it encodes for and hour and fifteen minutes usually. Then I save the last bit of it and then burn it on my cdr at 16X instead of 24X to make sure there are no errors. I put it in my dvd player and sometimes during the movie the problem occurs. Please help me this whole thing is getting really annoying. I did From hell.avi yesterday and the movie was unwatchable because of the problem. Thank you for any help that I may be given. Please dont flame me and tell me to go search.

I assume the source avi is "in sync" (not the boy band) before you attempt to encode. If it is not then it most likely cannot be fixed. I would use nandub instead of virtualdub to save the wav from the avi. Nandub is a hacked version which handles non-std audio and is available from www.doom9.org I would encode the audio separately from the video. Use tmpegenc to encode the video to whatever settings you want. Once you have a .wav file of the audio try using CDEX from http://www.cdex.n3.net/ to encode the .wav to mp2. Under options, settings change the encoder to 'built in mp2 engine' or something like that. You can pick the std settings of 224kbps etc... Once you have a .m2v or .m1v and a mp2 file mux with tmpegenc or bbmpeg. If you have the same number of seconds of video and audio and the source was in sync - you should have an in sync mpg file.

If you play the converted mpg on your computer does it also get out sync?

If it is a framerate conversion problem I can send you my guide which goes through step by step how to correct the 'gradully losing sync issue'

Basically it involves

1) Extracting a wav file from the avi using Virtualdub
2) Using avifrate to convert the avi to the desire fps and noting down the new video length in seconds to 3 decimal places
3) Applying the frame rate change to the avi using avifrate
4) Stretching the wav (keeping pitch and using low precision) in cooledit to the exact length of the video
5) Encoding in TMPGenc using the avi altered by avifrate as the video source and the stretched wav as the audio source
