:cry: o.k I've tried this 6 ways from sunday so to speak. When I rip the movie everything is in perfect sync. Then after it goes through DVD2AVI that's where the problem is. After DVD2AVI I thne proceed as usual with the MA script Headac3he and so on. When it's finally muxed the sound is way off!!!

Is it possible that some DVD's just won't frameserve through DVD2AVI correctly? Incendently contrary to my prior post I've gone back to using DVD2AVI 1.76 I have tried other DVD'S just to be sure and every one that I've tried will rip and frameserve correctly.

Has anyone had this problem????

As every piece of software DVD2AVI isn't 100% sure; There is always a "black sheep" for every tools and everyone.

It seems you found yours :-)

nighthawk 02-16-2004 12:50 PM

is there any other software that will do what DVD2AVI does?

I take it by "black sheep" that you mean that this is a program glitch?

Dialhot 02-16-2004 03:31 PM

No what I mean is that there is always, in everything, a situation that works for everyone and refuse to work on your PC. You can do whatever you want, copy/paste exactly the configuration of your neighbour for who everything is okay, it refuses to work at your home.

That's how computers works :-)

BTW, there is no tool like DVD2AVI.

But I suggested a long time ago to estimate the delay "with your hear" and set it manually in headache. You never answered on that.
The same, you never said if the delay is constant or varying.
And finally, you never solevd your problem with headache :!:

In sum : you ask a lot but don't give feed back on the hint we provide to you. Not very helpfull....

I apologize if I had not posted everything that was needed.

The delay is constant and I did try to do verything I knew how and followed all suggestions to to solve this within headache from negative delay to positive delay and nothing worked.

Since headache was not reporting a delay on it's own I was trying to work with number from tmpgenc and headache to come with the delay. that's when I got the 313ms off but that didn't solve it either.

I did post that when running dvd2avi that in the stastistics window under video type the movie would jump from film 99% to very low numbers that were NTSC and then back to film again only to be aroung 85% then it would slowly climb again and fall back to NTSC around 12%. I had never seen anything like it. That i why I posted that the problem must be the way dvd2avi must be handling the movie.

If the delay is increasing during the play, then you have a bad framerate issue somewhere.
Dialhot You had posted the above earlier and I'm really not sure at all how to check for a bad framerate or what to do for it either.

Again I apologize for not having posted to all of the hints I thought I had. I had to walk away from this one for awhile and then come back to it. I think that the "bad framerate" might play into this giving what dvd2avi is doing. It doesn't look as if the delay is varying but it might ever so slightly where I'm not noticing it.

According to your hears, absolutly nothign changed ? or was 313 too short (or long) ?

For sure, it's not common.

I never said it wasn't. But from the beguining I told you that if the problem is constant, all you have to do is to "estimate" it from hear and set it into headache.

You just said your delay was constant :!: So this part is out of subject.

By varying I was talking about something that is barely noticable at begining, increasing constatlly and finishes to be very obvious at the end. Not something that change back and forward during the playback.
If you are in the late case, for sure you can't do anything ! That would mean that the framerate isn't constant during the playback :!: (that's perhaps why the stats of DVD2AVI are so weird)

I just went through the movie again and yew it is more out of sync at the end than my corrections are at the beginning. So I think the framerate comes into play. Though I don't understand it completly. The dvd play fine on the computer, just fine after the rip, as well as on the standalone dvd player.

When it's processed through dvd2avi that when everything goes to **it.

I think it's fairly certain that nothing we do is going to solve this one. Could you further explain this bad framerate to me as I don't understand how erverthing is in sync on the dvd then even after the rip.

The actual movie framerate is 29.970 and after I use forced film it is 23.976 if that helps.

That's because DVD2AVI can't modify the framerate in the middle of the movie where A DVD player can.

When you have a 23.976 pulldowned DVD, the player reads it at 29.970 (that is called "pulldown during playback"). But the movie is actually at 23.976 and there is just a flag that tells the standalone "read this at 29.970 not 23.970".
Your movie seems to have parts where this flag is set and parts where it is not. A standalone can handle that, but DVD2AVI use either 23.976 or 29.970 for ALL the movie.

That's where your problem can appear. And that's why I told you you can't do anything if this is the case.

FORCE film is exactly what I wanted to say : as you can see, you _force_ DVD2AVI to use film mode for all the decoding.

Note: give a change to "automatic" mode, just to see what happens.

nighthawk 02-17-2004 07:14 PM

There is definitely a framerate issue here, at one point I was up to 1900ms delay correction. I never did gain on it either, setting dvd2avi to auto didn't solve it. I would have to say that the dvd itself is badly encoded.
