I have tried unsuccessfully to convert a DIVX movie to MPEG2 (DVD).
Each time I encode (using TmpGenc) the sound is out of synch.
I have tried extracting the sound (WAV) file using VitualDub and then encoding to DVD (using TmpGenc by selecting the DIVX as input for video and the WAV file as input for the audio) but the sound was nowhere near being in synch on the output file.
I then selected the original DIVX file for input as BOTH video AND audio and while the sound appared to be in synch at the beginning is was out by maybe 2 seconds by the end of the output video.
Using GSPOT (to determine codecs on the original file) it shows that the STREAM TYPE is OpenDML AVI, the video codec is div3 DivX 3 Low-Motion with a bit rate of 825 kb/s and 23.976, and the audio codec is 0x0055(MP3) ID'd as MPEG-1 Layer 3 with a bit rate of 141 kb/s (70/ch, stereo) VBR LAME3.89 48000 Hz.
Should I try TooLame to extract the audio?
What is the answer to fix this synch problem?
Thanks
John

convert the audio to 4800 mhz and save the file as wav using virtualdub. then convert the wave file to ac3 / 192 bitrate using ffemggui.
when you're converting the avi to mpeg2 are you setting the output frame rate to 23.97 with 3:2 pulldown encode mode?
use tmpgenc dvd author or other dvd authoring program to mux the video and audio. -
convert the audio to 4800 mhz

If the sync problem still exists after remuxing and buffing and waxing then you will have to either stretch or shrink the time line of the audio with a sound editor program so that it matches.,takes some work but can be done.
