I have just made a VCD and the sound is out of sync.

I still have the .m1v and .mp2 so how do i get it back in sync??

and another audio question if my divx has ac3 sound do i still get it the way Black prince describes in his guide (vdub full process,HeadAC3he mp2)??

Thanks

Sync problem:
1) Determine which happens first by playing frames where there is
speaking and determine which comes first. The voice is before or
after movement of the mouth.

2) Use bbMPEG and multiplex again, but this time when you get to
tab "Program Stream settings" put in the settings from the Guide and
at the bottom of this tab "Startup Delays" you can set a delay for
audio or video. 1000ms ~ 1 sec. So, if the voice comes 2 seconds
before the mouth movement set audio to 2433 and multiplex. Play
back the .mpg and your sync should be closer to correct.

Audio: Even thought your audio is .ac3, use the same process as
described in the Guide. This should work The only time this might
not work is if the format is .ogg

Whats the easiest way to get it in sync? I mean how do i find out how far the sound is in front or behind?

i have tried about 20 times and still cant get it right

One way is to view the mpg in WMP and skip to a part where there's a noise like an explosion or something and time the offset with a stopwatch.

Here's a script using filter "avsmon". You must include the
audio .wav file. "Avsmon" displays the movie and the audio sync
in VDub preview, allowing you to change the delay as the movie plays.
I got this filter from Doom9. Do a search in their forums for it.
COOL Uh! When you come to scenes that talking occurs, you just
adjust the delay until audio and video are in sync. Write this
delay value down ( 1000ms ~ 1sec) and use it in BBMPEG.

LoadPlugin("E:\DVD Backup\2 - DVD2SVCD\MPEG2Dec\MPEG2DEC2.dll")
LoadPlugin("E:\DVD Backup\avsmon.dll")
#
video=avisource("D:\Temp\Divx.avi")
audio=WAVSource("D:\Temp\avseq01.wav")
#
LegalClip()
GripCrop(352,240,overscan=1)
GripResize()
TemporalSmoother(2,2)
AvsMon()
LegalClip()

I used this a few times and it worked

@MrCoopz,

Here's a link for "avsmon":

So it has to be the origanl wav that u get from VDub?

cant u use the Mv1 and Mp2 files?

@MrCoopz,

I save the .wav and .avi files just in case of sync problems and/or for short
test clips for picture quality. Even after I burn the final .mpg and play
on my stand-alone DVD player for the final test, do I remove all video
files. As I gained more experience with KVCD, I picked up tricks and
better ways to get around problems. Sync problems use to take me
alot of time until I started using "avsmon". Now it's a cinch
