I did a search here before asking. I checked the Q&A and didnt see a solution to my particular problem. With that said, heres what is happening:

The movie is Business of Stangers, I have the vobs, no dvd. Vobs are in synch.

Every time I try to encode the movie, The MGM Lion comes up and growls, but no audio. About 10 seconds or so later, You can hear him start his growling. Entire movie is out of synch. When I play the first vob, there is a blue MPAA rating screen that comes up before the MGM-Lion screen. This is not in the encoded video and I assume this is why the video is ending up out of sych.

How can I either make sure the MPAA screen gets added to the encoded video to keep the audio in sych or either move the entire audio track to start earlier? I would assume the former would be the best route but unsure how to complete the task.

Thanks for any help in advance.

What did you use to rip the VOB's?
If you used anything, but the two inluded rippers please rip the Vob's again with the included rippers and if there is still a problem then reply.

If you did not use the included rippers and you don't have the DVD there is little that can be done with DVD2SVCD. Even if you did this sounds like a case that you will need to re-rip the DVD with either the included rippers or something else.

Yes I reripped from the vobs I already ripped. The result is the same. As I stated before though, if I view the vob1 file with windvd, the movie plays back correctly. Is there anyway to adjust whatever is telling dvd2svcd to not rip that 10 sec trailer video? If I can get that MPAA trailer to rip all should be well.

I wasn't suggesting to re-rip the already ripped files. I was saying to rip again from the DVD with the included rippers if you didn't use them to begin with.

Why are you trying to re-rip them? Uncheck ripping and just select the IFO off the HD. I know it's said to re-rip for A/V sync issues, but this is a different issue.

When you originally ripped the DVD what did you use? If you used anything other then the included rippers then most likely you are out of luck with DVD2SVCD.

If you still had the DVD then there might be a work around, but you cannot use the already ripped files. These are probably useless.

since you were trying to make a svcd-compliant mpeg2stream, i suggest you takee the completed mpeg2-file and use bbmpeg to demultiplex video&audio.
after that you multiplex the two streams with bbmpeg and set the audio delay(i think itīs called that way) to the amount of time the video&audio are out of sync - which in your case would be a negative value eg. "-10000" for 10secs.
:D

FORC3 why would you go to all that work when you can adjust it in DVD2SVCD?

There was a post about a similar problem with 2 4:3 DVD's that became out of sync when the "formatted to fit your screen" image came up. The only answer was to rip the DVD with Smartripper and particular settings. I think this might be close to the same issue.
Unfortunetly you need the original DVD. You cannot do this from the already ripped Vob files.

Have a look at this thread. I think it is the same problem, but you need the DVD.

i was assuming that lonewolf454 already converted the vobs to a Svcd-compliant-MPEG2-stream, which is not in sync.
imho it would be less work to just adjust the audio&video-stream than to do the whole conversion again (given that it takes 12-20 hours on my pc), since itīs quite easy to fix (and not nearly as time-consuming).

No, you simply use recover and as long as you still have the mp2 and the mpv files you can keep muxing forever with all the changes you want. No need to do it all over again.

Guys dont get mad at me but I am unsure then can I rewcover and just remux the files then and change setting in bbmpeg(the advanced setting) to remux with a delay in audio of -10000? This would make audio stream start faster correct? I tried just going to the bbmpeg executable files in the dvd2svcd, but unlike tmpeg, they have no option to demultiplex.

So can I remux with the files I already have in the movie folder? I of course do not have the dvd anymore as I have put this one off for five months now.

Thanks.

It might be possible, but it will be very hard to get it right. It will be allot of work and trial and error.

You are better off delaying the video start then saying - anything for the audio.

I sure hope that you can fix that copy of you Aunt Bessy's wedding. Worse case maybe you can borrow it back from you cousin and rip it again using the method in the linked post.

I know it isn't a copy of a real movie since we don't do that here.

FYI: With TMPG you can also adjust unsynced video and audio. Its under the settings->advanced tab where you have to double click the source-range filter.

At the bottom of the screen is an audio setting that will shift the audio stream forward or backward in time (as compared with the video stream).

I have to use this option when I capture video from my capture card. I have a constant time delay of (approx) 6 seconds that I can correct for with TMPG.

BTW: It is extremely difficult to find out the exact delay time in milliseconds. Its best to find a piece of the movie with clear actions that you can easily adjust with the acomanioning sound. I have used a capture of a drum-scene. The close-ups of the drummer enabled me to exactly adjust audio and video.

I never used BBMPEG for this, is this process easier with BBMPEG?

Problem is I havent figured out how to get bbmpeg to demux and remux the mpeg files. Even in the help section under bbmpeg there is nolthing about demuxing or how to do it.

I sure am ready to see Aunt Bessie in that wedding dress

TMPG -> File menu -> MPEG Tools.

Happy (de)muxing :)

If you still have all the files from DVD2SVCD then the mpv and the mp2 are still there. You can simply use recover and start from muxing and cutting.

Thanks Mark.

I had tried what Force3 had recommended first, added a -10000 to the audio stream which was to hopefully actual advance the audio by 10000 ms. Well It didnt work and encoded movie result was the same as before with the 180 default setting.

I tried your recommendation of delay the video. Tried 10000 first, wasnt quite enough. Tried then 10180, and ended up with 10350 which was as close as I could get it. Perfect synch at beginning of each image, and slightly off at end of each video, but within half a sec, close enough!

What I didnt figure out, with a delay of video 10000, the bbmpeg00.mpg file was in perfect synch, but after I ran it thru iauthor and cdmage, it was off again slightly, thus the end setting of 10350 on video. I dont understand this because other movies turn out perfect synch in bbmpeg file as well as the bin file.

O well, I have finally got this movie off my hard drive and I am grateful. Thanks again, and I hope this post helps someone else that surely has the same problem. We are all learning from each other here.
