[TMPGEnc]Every movie except the first has async sound on dvd

[Majin]

Hello,

i created a movie dvd with tmpgenc, with menu an such - i wanted to burn 10 movies (futurama) on one dvd. However the problem is - only the very first movie on the dvd plays well, all others have serious async problems - after about 5 minutes in each movie, its like 2 - 3 seconds.

The movies were originally mpegs1, they are all the same

Video : 29.970 B/s, 352*240 (4:3)
Audio : 24 Kbps, 44100 Hz

At first i thought it was my dvd player which had a problem - but than i tried to play the files which created by tmpegenc on my harddrive and they had the same problem.

The original mpegs play just fine !

The movies only differ by a few seconds in length, but i think that doesnt matter - could anyone point me out the error i made ?

Thanks,
Regards

Using what? Using some software multimedia player doesn't say anything about the integrity of the file, or its suitability as DVD material. I'd bet it's lousy source material that's causing you your trouble.
Anyhow, how do you go abot making these mpegs DVD compatible? For one thing, the audio has to be 48 kHz. mpeg1 at 352*240 is valid DVD video.

Thanks for the reply, so that means i have to create the 48khz manually ? I thought tmpgenc would take care of that... Could you point me out how i easily achieve this ? And why does the first movie work well, but not the others ?

[mats.hogberg]

TMPGEnc doesn't - TMPGEnc DVD Author may do. You still haven't told me how you go from source mpeg1 to DVD.
Why the first works but not the rest, I can't tell. Maybe it's in a different format? It's hard to tell from here... Do you author each ep as a separate title, or just as one title, one ep=one chapter?
To resample at 48 kHz, demux, convert mp2 to wav, resample to 48 kHz using GoldWave (or SSRC) then reencode to mp2

sorry, i was a bit unclear - im using TMPGEnc DVD Author, so befor using the author i have to reencode the audio stream - how do i put the video stream and audio stream together again ?

Each ep is a chapter of its own.

Thanks for your help

[mats.hogberg]

Each ep is a chapter of its own.

What if you make each chapter a title of its own?
Does it make any difference which mpeg you use as first chapter?

I tried to switch the order, the track1 was just coincidence - the first ep was the only one synced - no matter where i put it at.

The only working ep has the same specs like every other ep so i dont know why this one is synced.

Sorry, but i dont quiet understand the different between chapter and title here. Every ep is a track of its own in tmpgenc video dvd.

Edit : Well, i used virtualdub to save the audio stream as 48khz as you suggested, during dvd creation i selected the orig mpg as video source and my saved wav as audio source - the result was the same - still async - so that was not the error.

anyone ?

most likely the audio in you original files was recorded with a variable bitrate. you need to open the problem file in goldwave and save the audio as wav. then open video file in dvd author and then change the orignal audio with the audio you made from goldwave and let dvd author take it from there.

Have a look at:

Perfect AV Sync: SVCD/VCD to DVD

If your mpegs have been edited (to cut commercials etc) or dropped frames - it is likley that this will highlight it.

If you have a gradual sync issue then this is down to the capture process (clock timings etc) and can be resolved using:

https://www.videohelp.com/forum/viewtopic.php?t=140540&start=0&postdays=0&postorder=asc&...hlight=gradual sync

Also does one rogue file on its own (in the authoring software) still have the issue?

[Majin]

What do you mean with rogue file ? The created *.vob files ? Than yes...

That gradual sync guide gave me the right idea - after checking the movie length and the mp2 length i found a difference of about 7 seconds.
Now i used goldwave, i set the sample rate without resampling - first i tried to match the exact movie length - but that didnt work that well - i figured than about 0,5 sec shorter was the perfect match right till the end of the episode. I dont know why it wasnt a good match for the same length.. My final playrate was 43970, the perfect match should have been 43955 tho - which is like 0,5 sec - probably the video and sound start at a different time (blank video ?).

Thanks for the advice, now this is gonna take an awful long time to convert 60 episodes - i wish i could just use the video time, but i see i will have to manually match each episode, sigh.

EDIT : Well, apprently i can also do it like the first guide suggested just rencode with tmpenc plus - it takes about 25 minutes for every ep - but the advancment is that i dont have to do it manually which is a plus, and i dont seem to lose video quality i think.
