Audio out of sync 5 seconds - DVD ripped with DVD Decrypter + AutoGK :(

Hi everyone,

I ripped a DVD today with AutoGK and DVD Decrypter using this guide: http://www.rita.lt/guides/AutoGK_DVDtoAVI.htm.

The original DVD contained 2 angles: Angle 1 was English credits and Angle 2 = Japanese credits. It contained Japanese audio and English audio. I chose to rip Angle 2, and wanted the result to have Japanese audio and English subtitles. The video is perfect - my English subtitles encoded in perfectly - they matched the mouth movements exactly.

But, the audio is consistently out of sync with the video by about 5 seconds throughout the movie. I followed the directions, word for word. Does anyone know what I did wrong, or how I can get the AV in sync? Thank you so much, I hope someone can help me.

Hi-

Rita's guide is excellent. But she's not all that clear on how to decrypt using DVDDecrypter. You should be using it in IFO Mode (Mode->IFO, at the top), and getting only the movie with the angle you want. Maybe you did that. For newer movies (with newer protections), sometimes RipIt4Me in Movie Mode is the way to go. Otherwise, assuming you have the latest AutoGK installed, I'm not sure why the audio wound up out of synch. It's easy to fix, though.

Open the AVI in Media Player Classic. Right-click the screen and go Options->Filter->Audio Switcher->check the "audio time shift" box, and fill in an estimate of the amount of asynch. Hit "Apply" and test it out. Negative values are to make the audio play earlier. 1000 ms= 1 second. Resume playback. Adjust until you get it right. At that point you'll know how much the audio is out of synch and how much to set the delay in VDubMod. Then open the AVI in VDubMod, set the Video for Direct Stream Copy, go Streams->Stream List->Right-click the audio->Interleaving->Audio Skew Correction, and set the same delay as you found using MPC. OK your way out of there, go File->Save As, give it a new name, wait a minute or 2, and test it out.

When all done, either uncheck the box or set the audio time shift back to 0 in MPC.

Hi-

ore whas it the switched?

You have it switched.

sound comes about 4 sec after picture

Then you want to make a negative (or -4000 ms delay) to fix it. Setting a positive delay makes the audio play later in relation to the video. A negative delay makes it play earlier.

Remember that when testing the fixed AVI, if you use Media Player Classic, you have to have turned off the delay. Otherwise that delay you set will apply to every AVI or VOB you play using that player.

One moore question, how do i sett the sync if it is a MPG-file then?

i have counted out the correct time-value , but the problem is if i try to complete it with VirtualDub to, i must save the output as an AVI, and i dont wanna

how should i do?

How do you set the synch if it's an MPG? I don't mess with MPGs, but if the audio is AC3, then use DelayCut to do away with the delay. If the audio is originally a second off from the video, then in DelayCut, set the delay for 1000 ms (either + or -, depending on if the audio plays before or after the video), to either cut a second from the beginning of the audio file, or to add a second of silence to the beginning of the audio file. Then mux the video with the fixed audio.

Me again

,

I don't have any MP2 audio with which to test, but I think you can use HeadAC3he for the job. Open the MP2. Set the Destination Format as Source. Set the delay you want in the Delay box. If it doesn't crash and leave you with nothing, then you can tell if it worked by comparing the filesizes before and after. A negative delay will make the output size slightly smaller; a positive delay will make it slightly larger.

There are probably other ways as well, but I don't mess around with MP2 audio much.

Yes, BeSweet can convert MP2 to AC3 if you wish, but since MP2 audio will only have 2 channels, I don't think it create anything but 2 channel AC3, which is also known as AC3 2.0.

It is NEVER wrong here to create a new thread.

I know nothing about Delaycut. I can't answer that question.

Demux means that you will create a separate audio only file from the combined audio+video file (DVD) that you have.
