Stumped... Just can't figure out audio problem!

[chiga]

I've reached an impasse... I have a single avi file (712MB) which I am trying to encode to svcd in two parts (by using the source range in tmpgenc). The first part came out okay. The second part keeps having messed up audio synching!!!!

My tools: vdub & tmpgenc

I've scoured the forum here & have tried multiple attempts, but nothing seems to work. I tried frameserving from vdub to encode in tmpgenc (my usual method), and the first part came out fine, but the second mpeg file has major audio synch problems.

I tried adjusting the audio gap, but I don't think it's consistent since the fix in one area doesn't fix the synch in another area.

I've tried just encoding the avi directly in tmpgenc, but that results in no audio. I also even downloaded the special vdub to scan for junk frames (there were none).

Note: Vdub does show a message that it has "detected an improper VBR encoding in the source AVI file ... may introduce up to 94361 ms of skew from the video stream" ... but why does the first half encode okay... and why is the audio just fine when I view in windows media player?

I don't know what to do... I can't save the wav out from the avi because of my hard drive space limitations... Is there an easy solution to my headache?

so you saved the audio to a wav file using vdub or what. you said you used vdub but at the bottom it says you didnt because of space limitations.

if you didnt use vdub to save a wav file i dont know how the audio was in sync on the first cd since you said you get that error message when you load the video into vdub.

delete some stuff you dont use, make a wav file, then delete the wav file when your done with it.

i think thats the easiest way to go about this

try it and reply

I used vdub to frameserve & check for junk frames. I tried separating out the wav, but it is projected to be over a gig in size, and I ran out of disk space (I've already pared down to my bare necessities)! Any other suggestions?

Chiga . . .

You have some serious hardware issues to sort out first: 4gig of disk space is just not enough to do a lot of what you'll find suggested here in the forums for correcting your sync problems.

If you haven't got the tools handy, then the fixes just ain't gunna work *wry smile*

hey bolta... don't be such a naysayer.

from the time I started researching and learning how to convert, there have been so many times that I was at the point of giving up & throwing in the towel... it has such a long & painful learning process for me.. but ultimately, extremely rewarding, because when there's a will, there's a way!

I am constantly amazed at the wealth of information available all over the web, thanks to forums like these and other fabulous websites.... And even with my pathetic computer setup, I've still managed to extract solutions to create svcds and workaround problems like a small hard drive, ac3, codecs, MV on my TV/VCR combo, and so many other "little" obstacles (which seemed like mountains when I first encountered them)!

Anyways, I'm trying to get a different version of the avi file to see if this works, since it doesn't seem like I'll be getting any workable suggestions to my problem.

I don't know if anyone's reading this thread, but I also have a separate question... Does anyone know if different DVD players can produce different audio synching playback? For example a Daewoo seems to play a SVCD fine, while a GoVideo unit shows audio synching problems on the same disc..?
