I have been trying to put some avi's onto dvd with divxtodvd and the sound is massively out of sync, any ideas?
Try decompressing the audio in your AVI file before converting it.... If you PM me with your e-mail address I can send you a Small tool for Decompressing the audio in your AVI file.... Many AVI files downloaded off of the Net have VBR MP3 audio which will allways go out of Sync after encodeing so the solution is to decompress the audio so this Doesn"t happen.....
I would greatly appreciate this 'tool' as well because I have been having the same problem with my own AVI files when burning them to DVD. Even when trying to save the VBR MP3 as WAVs in VirtualDub or the like won't work for me.. Thanks!
Once the sound is compressed, the reason for having a sound not-in-sync with the video is only having a CONSTANT delay between them, because once you author the DVD with the video obtained from an AVI file and an uncompressed WAV file extracted from it you will not add extra un-syncs between A/V. My suggestion, but you'll have to find 'by ear' the right delay to add to the sound which causes A/V synv (e.g. "300 ms"; having a 100 ms = 0.1 s precision is enough, for me). Run HeadAC3he and load the uncompressed 'audio.WAV' file you obtained from the AVI, using VirtualDub in audio___full processing mode, as always. Increase the 'delay' value until you add the needed number (the precision which HeadAC3ha allows you to have is 1 ms = 0.001 s, which is more than anough). Until you've put the right delay value (you'll have to spend some time, since the arrow increase of 1 ms the value and you cannot enter the number directly) , press the 'start' button (the destination format, by default, should be WAV and you have to save in WAV format) and wait the time needed. Once you have the 'audio.2.WAV' file, use it, once you have checked the A/V sync: you can check with TMPGenc using the VCD template with 'very low quality (very fast)' using various 'select range' intervals, to be sure. Once you have a WAV in-sync with the video, make your DVD in the way (using the AVI for the video and the 'good' audio.2.WAV file for the sound, obvously) you usually do...
