Bad Audio

[bozoka45]

I have a movie, and the audio seems to be about 1second behind the video (not alot, but very annoying) is there anyway that i can rip the audio (using the method found on this website) and then somehow make it so that it goes with the video? I was thinking of adding a small blank segment to the front of the video, and hope they would be aligned correctly

No, use TMPG or something else to "demultiplex" your video & audio...a common prob with TMPG....then you can use BBmpeg to multiplex them back togther...because BBmpeg has options of delay or speeding up the start times of the video or audio...

I just finished dealing with this problem(happened to find a new one in a different field) but what I did was:
- Used virtualdub to split the audio into one single wav. track of the entire film. In my case about a 1.3 gig wav file.
-Then I downloaded the sample version of cool edit and inserted some blank time in front of the sound, something small like 0.7 sec.
-I then made this my new sound source for TmPEGenc and did a test at low quality of the first three minutes. Burnt it and checked where my sync was.
-Did it a couple times trial and error but the audio synced.
-Then I went into the advanced folder in TMPEGenc and clicked on the source range selection, set my in and out for disc one and made it part of my batch capture.
-Do the same for disc two in the advanced setting for the second half and add to batch capture.
-Start the render.

It all worked for me but being a dummy at the last second I got 80 minute discs instead of my 74 CD-RW test disc, changed the bit ratio and created a whole new problem. But this will work for your audio sync.

By the way if the movie you are working on is Memento the time to add in front is 0.5 sec for 352x240 and 0.6 sec for 720x480. Go with the smaller size, gets pretty digital at the large size.

See, my problem is worse. At some points, the Audio and Video are synced, and at others they arent. I just dont get it. I would be very hard to fix.

thank god monkeybone... i have been screwing with this movie for over a week! thought the problem was that the original avi was in pal format (352x288 48k audio) so i did use vdub to rip the audio, got my hands on the full version of cooledit, but cant quite figure out how to use it yet, heh.. nothing i have done so far has worked, but by god, when i get home frmo work i will do what youve said with your times, and finally be able to watch this thing!

happy to announce that using tmpgenc's source range setting and the -900ms delay on audio, this movie has finally been converted with perfect avsync.
