Audio out of sync??
 

Here is the dilemma:

I ripped my movie using DVDcrypter in file mode
Used the latest version of DVD2AVI to frameserve, my settings here were

forced film
audio: decode to wave file

After the frameserve I loaded my wave file into HeadAC3he in which I converted it to MP2 resampled to 44.1 khz at a CBR of 112

Then I loaded my d2v file into MA Script ran through tmpgenc and then muxed using tmpgenc. the audio is out of sync (behind) this has happened with two different DVD'S.

I should mention that Headac3he doesn't show any audio delay it's at 0ms.

Has this happened to anyone before & if so is there a fix?

The original DVD is in sync.

You should'T extract a wave file, You have to exr´tract the AC3 file and then DVD2AVI shows you the delay wich you can correct with HeadAC3he.
And all is in sync.

I tried that in DVD2AVI to "Demux all Tracks" however when I convert in Headac3he the resulting mp2 file can't be muxed in tmpgenc I still have to convert to a wave file in headache. Am I missing a step?

I should mention that during the DVD2AVI cycle the "video type" in the information window bounces back and forth from NTSC to film and the film is around 87 - 88%

You not only set "Demux al Tracks" In this field of the Programm is another point demux and another Option Automatic select both and the prog extract the AC3 File.

Surely ! Headache does perfect mp2 files so you should make something bad. use besweet if you can't use headac3che.

O.k I demuxed to ac3 file and Headac3he is still telling me that there is no delay. The version of dvd2avi I am using is 1.77.3dg1.0.0RC2 and I don't see a auto select anywhere. I am also not familiar with BeSweet I've tried using it before but it's more confusing to me than Headac3he.

I feel it's a problem within the DVD2AVI process and it happens with version 1.76 also.

When I rip the "entire" dvd to the hard drive I can play it and there is no sync problems so I figure the problem is not with
DVDcrypter.

no matter what I do the audio is out of sync with the video after i mux it. Is there anyone who has ever had this happen and found the solution?

hmmm,
You mean you burnt the resulting mpeg and it's out of sync watching in the standalone or you are just watching it in your pc?
I say this because I had audio out of sync issues, long before I joined the forum, but these were only watching on pc.
If I burnt it to a cd there were no problems watching on standalone.
I never figured why this was happening because suddenly it got cured by itself :roll:
Could you try to burn it on a CDRW and try it?

If the delay is constant, yes, some had the problem and the solution is to "estimate" the delay by watching the video and then re-encode the audio with this delay setted in heada3che.

If the delay is increasing during the play, then you have a bad framerate issue somewhere.

Woow,
I would agree 100% with you if it was a DivX source but it's supposed to be a DVD. Would you find that possible :?: :roll:
Unless this DVD is not an original DVD and has been made from a DivX but then there would be out of sync issues with the source also. :roll:
What do you think, Phil?
Cheers

Constant delay is possible even with DVD. See there :

Sliding delay is generally due to bad DIvx encoding, I agree.

In the video type info box of DVD2AVI it will say film at 98% for a short while and then bounce back and forth from NTSC to film finally ending up on film around 86% - 89%. I do notice certain areas where it's only 12% or less just for a short time. Could this be where the problem is?

I did rip the entire movie too my HD and it plays fine no sync issues at all when watching it. So I feel that the problem is in DVD2AVI.

I have my settings at forced film & decode audio. I have tried to demux to ac3 however when I do Headac3he converts the ac3 to mp2 but with an ac3 extension so it won't mux in tmpgenc.

I've tried BBmpeg but I've found tmpgenc to mux better.

Not really sure what to do with the DVD2AVI problem.

suggestions would be awesome!!

Back again two post above : you have a problem with headache !

Headac3che does PERFECT mp2 for tmpgenc. Stop lookign further, decode in DVD2AVI is awfull.

Solve your problem with headche !

so when I set up DVD2AVI should I set the audio to demux or decode to wave so that I have something to put into Headac3he? I've tried both ways and always use Headac3he to convert to mp2 file. Am I missing a ac3 codec? I've always decoded to a wave file in dvd2avi and never had any problems except for now.

You probably don't have problems that you heard, that is different. This time your hear bring you back to reality :-)

You have to demux with dvd2avi then put the ac3 in headac3che and ask it to do a mp2 ! AFAI remember, the GUI of headeache is trivial and you shouldn't have any problem.

:crashed: O.K I've been going nuts all day on this 8O

When setting the delay in headac3he how does one know which way to go in setting up the delay? + or - delay.

Here is the info from headache 1:58:00.224

Video is 1:57:55 according to tmpgenc and thats loading the d2v file directly in. I arrived at the figure in source range by going all the way to the end of the movie.

if my math is correct my delay is 313ms off or am I off? So which way + or - on the delay

I'm really starting to feel :smileysex: about this except I'm not smiling

Hi nighthawk

Also when you demux as ac3 it will tell you the delay

when you load the ac3 into headach3e it will set the delay automatically

I am very new to this but this is how it works for me

sorry to chime in if i'm totally off base (it was kind of hard to follow this thread)

There doesn't show a delay in headache, when I load my file in it show 0ms delay. That's why I'm having so much trouble with this one.

It should be - but trying both will take you no more than 10 minutes ;-)

Judging by the length of your audio and video files, I would say that your audio is 'behind' the video, right :?:

If that's the case then you need to bring the audio forward by reducing the delay, so -313ms
