Video and Audio problems

[Ashendon]

I am having trouble when converting an avi file that has the appropriate audio and video to svcd-the audio slows down and doesnt match the video-i have read that it is impossible to fix it...so how can i convert it over from avi to svcd without audio troubles?

Make sure the source AVI has the same framerate as the destination SVCD. OPen the avi in virtualdub and select file->file properties to find out the frame rate of your avi file. Then select the TmpGenc SVCD template that has a matching frame rate. This should solve many sync problems encountered by beginners to this stuff.

Also, read the guides on this site, they are full of useful info.

thankyou...but i have followed all the how to's in trying to fix the audio sync problems and nothing has seemed to work...i wasnt able to find any mention of trying a different template for svcd to match that of the avi file...

Well try it and see what happens, if you are lucky it will fix your problem. Let me know how you get on.

i am trying nero now with the svcd plug-in that lets you convert files to svcd...so hopefully it will also repair the file i am trying to do

[bugster]

Well its nice to be able to give advice to newcomers to this pastime, even if it is completley ignored!!!

I did try what you said and 15 hours into the dub...there was an error in the movie...i scanned it and there were no errors detected and then i restarted the dub and the file that came out had no sound still...so then i restarted the dub again...using the extracted wav that i used virtual dub to extract for the source audio and it still didnt turn out and yes i did use the right template for the movie that I was doing and no i didnt ignore you-just a lot pissed off that i have to waste so much time because one setting is off somewhere by a bit(why cant there be a standard for the movies files-setting wise?)

I've currently spent the last week trying to fix audio sync problems when doing divx to svcd conversions. The problems I've had is mainly with VBR MP3s in divx, or doing PAL to NTSCFilm conversions, but in any case, the audio is always out of sync when played in a DVD player, but fine in a software based player (WinDVD 3).

So far, the only way to consistently get the audio synced was to:

1) rip the audio in VirtualDub

2) encode the video using TMPGEnc

3) use a utility (Bitrate Viewer) to get the total number of frames of the video (.m2v)

4*) open up Cool Edit and stretch the audio so the total number of frames divided by the encoded video frame rate (23.976|29.97) match.

5) encode the streched audio in TMPGEnc, making sure the frequency is 44.1kHz

6) multiplex video and audio in bbMPG (for SVCD scan offsets-enables fast forward and reverse on your standalone player).

If you encode the video and audio seperately, you can always just work with the audio so you can try a couple of different things without having to re-encode the video, which can take half a day.

I've even had sync problems where the Divx and SVCD had the same video framerate, but the one consistent thing was VBR MP3.

*You can most likely skip the Cool Edit step if the video framerates are the same, but when you encode make sure the frequency is 44.1kHZ.
