DivX Convertion Problems

[maccool111]

Have recently downloaded several full length movies that are DVD Rips.
The format of the files is, Video: DivX Mpeg4 V3 and Audio: Lame MP3 Encoder (ACM).
The problem starts when I try to encode to Mpeg1 using TMPGEnc. The Video and Audio end up out of sync. I have extracted the audio and converted it to an uncompressed .wav file using CoolEdit Pro2 and inserted the video and audio seperately into TMPGEnc but to no avail. The problem still persists. I've tried using TMPGEnc to adjust the audio gap but with no sucess.
Any one out there offer ANY help?? I'm Desperate.

In what way is the audio out of sync, by a fixed amount or gradual drift?

Check the framerate of the original avi and pick a TmpGenc template with a framerate that is closest to (or best, the same as) your source material.

To find the framerate of your source, open it in virtualdub and select File->File properties.

Are the downloaded files in sync before reencoding? If not you're screwed. Is the mp3 audio vbr ? If so and converting to wav didn't work you're likely screwed. Download CDEX, try to reencode the mp3 audio to wav and then to mpeg1 layer 2 224khz CRC with CDEX. Use tmpgenc to mux the video file it creates with the .mp2 audio CDEX creates and pray to the supreme being of your choice (Higgs boson - "the god particle" for you athesists and quantum physicists) that it works. If not - guess what - you're screwed and you didn't even get kissed!

Another way of solving sync problems: I did the following steps: install avinfo, right click on avi with audio async, mark on avi info, tab utilities, extract wav file, then re-integrate wav file, use tmpgenc to encode, and my mpeg file was in sync!

Her's a link to avinfo:
