Some problem about delay of audio file (NTSC) after extracted by Doitfastforyou.

[movieinmyblood]

I have one DVD (NTSC version - South America).

When I extract all the components of my DVD from Doitfastforyou. I have got MPEG file (movie) and AC3 file (audio) as always. That is satisfactory.

Next, when I compile both MPEG file and AC3 file into Scenarist, I can also compile both without any problem.

However, when I watch my movie, I really get lost with its result because the audio delays. Why does it happen like this?

In the past, all of my DVDs have never had a problem of delayed audio before, after compilation by Scenarist. This is the first time. Is there any software to help me out for having an audio file synchronized with MPEG file?

Thanks for any experts :thanks:

Do you know if it's drop or non-drop? Scenarist defaults to non-drop for audio, you might try changing it to drop and see if that solves the problem. (Delete the audio track from the the video stream, change the setting, and drop it back in.)

Does the audio slowly go out of sync, or is it out of sync from the beginning?

Also, when you drop the audio on the video track, is it the exact same duration? Scenarist isn't trying to offset it based on embedded timecode, is it? That's another possibility... Manually create the audio track (without dropping in the AC3), uncheck the little check box near the audio language selector, and then drop in the audio. See if that does anything different...

That's the only two things I can think of off hand that might do this..

Thanks for your prompt reply.

I will try your process and will update you again.

Big thanks!

Doitfastforyou is quite old (vStrip, DVD2AVI, ...) try with more actuallized soft to do the extraction (AnyDVD/DVDFab, DGIndex, ...).

And this isn't an audio problem but a decrypt/demux problem, here we can help you to delay/stretch the audio if you know the desired delay/stretch parameters.

RIK113 - The default is non-drop for audio. I change it to drop at Drop Type. But when it comes to DVD compilation, I can compile only MPEG, but AC3.

AC3 can't be compiled with the sentence below

AC3 audio VTS_01_P01-81-448K-E66T''''s resolution or drop type does not match with existing data

If I don't change Audio to drop, I can compile both together. No matter what I try to drop an audio, Scenarist won't allow it at all. Thus, I have to compile an audio file (non-drop) with MPEG file.

By the way, after being compiled, I can see that the delay starts at the beginning with the same rate of audio delay till the end of movie.

This is what I get.

Tebasuna 51 - I have never used other software before. So, in this case, what should I do?

Okay, if that's the case, it's not a drop/non-drop issue anyway, so don't worry about that.

Is the audio the same duration as the film in the timeline? (Is any of the video missing when you watch it?)

The easiest thing to do is probably just manually move the audio around until its in sync. When you click on the audio file in the track editor, you should be able to state what they start time to video is. Just guess how far out of sync it is, offset by that much and see if it sounds good... Trial-and-error, just keep doing that until you get it perfect...

I'm not sure why you are having the problem in the first place, but that should help you fix it. (Never used Doitfastforyou....)
