Open the MPEG in VirtualDub-MPEG2 then go to:

Audio -> Full Compressing Mode

Then:

Audio -> Compression -> <No compression (PCM)>

Then:

File -> Save WAV

That should take care of the audio file. When you encode your movie to MPEG2 use the WAV audio and the original MPEG video, all should be good.

[killerfabber]

many thanks....
so after this process i will have two separate files, one for video, one for audio???

sounds cool

[killerfabber]

hey mate, but tmpeg dvd author can't handle waw files

it says:


ILLEGAL AUDIO FORMAT FOR A STANDARD DVD YOU CAN ONLY USE THE FOLLOWING AUDIO FORMATS

DOLBY DIGITAL (AC-3), MPEG1 AUDIO LAYER-2, OR LINEAR PCM

what can i do???

thanks

Also you need in VirtualDub to activate Audio Conversion. The file must be 48000Hz, 16bit, Stereo. After that should work.

Are you editing these mpgs before you use Tmpgenc DVD Author?

The audio sync happens in TDA after editing with some programs. Strangely the mpg itself is still in sync after editing.

I have no sync issues after editing with womble mpg vcr and then using TDA.

In many cases you don't need to use an extra program to edit. Just make your cuts in TDA in the same window where you set the chapter marks.

[killerfabber]

i'm make no editing...
just opening mpg files into dvd author main window.......

but after burned, the audio goes out of sync ;(

[presto]

Don't use TDA to burn. That was another suprise. You can get OOS in the burn process. It happened to me once when burning with TDA so I've burned with Nero ever since.

[killerfabber]

oos = ???

anyway i don't burn with dvd author but with nero


any clue then why the audio goes out of sync???
thanks

Tmpgenc DVD Author sucks boatload of ass. Avoid it. Use a good authoring program like DVDLab or, if you can find it, Spruce Up or DVD Maestro. Audio sync problems are almost always due either to the use of inferior DVD authoring software, or some kind of edits or modification like demux/remux done to the raw MPEG-2 or MPEG-1 file.
The audio drifts out of sync because Tmpg DVD Author incorrectly calculates the length of the audio as opposed to the length of the video. In most DVD authoring programs, the length of audio and video must match perfeclty, to the individual frame. If they don't, weirdness (typically sync problems) occurs. This isn't hard to check. Do a demux and load 'em into an editiing program like Adobe Premiere which can read MPEG-2 and mp2 audio files. If the length of audi and video differs (this can be caused by dropped frames during capture), you need to avoid dropped frames during capture. I use a Canopus ADVC-100 or a PCI video capture card with VDubSync which resmaples the audio on the fly to avoid dropped frames. Bottom line -- you can't do much with dropped frames in your video. You ned to fix that problem first. That, or fiddling with an MPG file by editing it without using proper software like M2Edit Pro or Womble Mpeg VCR, are the main reasons for out of sync audio. When you capture video you may want to use a program that tells you whether you have dropped any frames -- something like Adobe Premiere, or Scenalyzer. I always check, and the readout always says zero dropped frames. That's what you should have. Otherwise, you're headed for audio sync trouble.
The only other cause of audio sync problems is PAL -> NTSC or NTSC -> PAL conversion. This is avoided cleanly and simply by converint audio to WAV and video to AVI, then re-encoding.

damn!!!
very cool explaination!!!!
thank u very much mate
so, i think the best thing i have to do is to use a different software 8)
later i will try on of those app...
i'll let u know
thanks

p.s. the mpg files are ok on pc, no weird audio problems....
so i think the audio matches the video lenght......

Sorry about that, I don't check the forums all that often. When you go to make the MPEG2 in whichever encoder you use, use the video from the movie you want to encode, and the WAV audio I had you extract. Also, when burning the movie burn at the slowest possible speed.

The mpg files on your PC will be in sync, but once put on dvd will mess up... You have to use Virtual dub to save WAV, then use Tmpgenc to Mulitplex the old video with the new WAV audio... Also, I do not know if you are a total newbie like me, but after using a ton of software, I found Tmpgdvdauther to be the easiest, plus it encodes the audio for you. Unless you know of a software just a easy, I would love to know do to the fact I get easily confused with DVD authoring... (VCD and SVCD okay!, but DVD... CONFUSING)...

[presto]

I never do this and I use TDA (Tmpgenc DVD Author) to make DVD's from mpgs all the time.

If it works, it works but the above post kind of gives the impression that this is some kind of rule when working with TDA.

I think you should look at whatever program created this mpg. Do you have this OOS problem with other mpgs?

[killerfabber]

thanks everybody for all the support....

i've tried the "dvdlab" app, but damn, it is very hard for a newbie
tmpg dvd author is really easier compared to that one....
i will tray again to sort out that sync problem remultiplexing with tmpenc (thanks bearbegr )

i've tried many mpgs!!!! everytime OOS

Could this be a PAL vs NTSC issue? I too, like presto, use TMPGEnc DVD-Author all the time to author my videos (home movies, VHS backups & DVD backups). I also usually work with the included audio stream. I've had very good luck working with MPEG-2 files created (encoded) by TMPGEnc Plus and ones created by my AVER TV Tuner real-time capture software. In the later case the audio and video stays in sync even when I edit out the commericals in a 2+ hour capture in TMPGEnc DVD-Author.

Also, I've used TMPGEnc DVD-Author to backup DVD-9 movies by, for example, backing up the Full Screen angle when the DVD contains both FS and WS and using TMPGEnc DVD-Author to reauthor the menus. Again no audio or video sync issues.

The only exception is when I'm backing my VHS movies to DVD. I capature these videos to my harddrive using the DV passthrough on my TRV320 DV camera. A 2-hour movie produces an 30+ GB AVI. I then encode this to MPEG-2 using TMPGEnc Plus. If I author this without any editing no problem. If, however, I cut out some from the start or the end, due to starting the tape to early or not being there with the movie ends, then I have had audio/video sync issues. So for these captures I have to start the capture at the start-point I want and be there to end the capture at then end-point I want.

Anyway ... I'm not sure if any of this helps ... but for me TMPGEnc DVD-Author is one of my "work-horses".

Are you saying that you have the problem when you edit the beginning and or the end (of these particular captures) with Tmpgenc DVD Author?

Yes ... but only on the VHS movie capture (> 1.5 hours) ==> MPEG2 encoded ==> TMPGEnc DVD Author. In any other case (e.g., TV CAP to MPEG2) no problems (so far).

[presto]

Killerfabber, I have an idea:

Download the trial version of womble mpg vcr. Open your mpg with it and then save it with no changes. Try this new version in TDA.

Womble mpg vcr is a great mpg editor. It will not re encode even if you do make some cuts. The process will only take a minute and I have a feeling it may solve your problem.

The process of running an mpg thru womble has "fixed" mpgs that gave me trouble in other applications. I don't know what it does but I think womble "packages" the video better somehow.

killerfabber-I've come in late on this, so excuse me if you've already tried any of this.

For starters, TMPGEnc DVD Author is a GREAT program-I much prefer it over DVD-Lab-as you've discovered, it's not the easiest program to master!! I do agree on what was said about not using the TDA burner though, it's spat out discs that wouldn't play on my standalone player before now. Just burned the save Video _TS file in Nero Burning Rom.

ok, that out of the way..lets just take a few steps back..

1-The MPEG2's you are looking to put onto your DVD-you have checked playback on your PC and they play fine, right? That means the files are good.

2-Does TMPGEnc kick up any kind of fuss about them when you load them into your project? I assume not as you wouldn't be able to create the DVD files, but if the bit rate is out of DVD Standard, TMPGEnc will only warn you-you can still go ahead and create/burn your DVD, but that could lead to playback issues on a lot of players.

3-When you have created your DVD files, have you played them back on your PC using a DVD software player? Do the files stay in sync when you do? If so, burn the files and then playback the DVD disc using the same software player on your PC that you succesfully played the files on before the burn. Is the disc now in sync? Now try it on your standalone player-If it's out of sync, check what the audio type your MPEG files used. Some players-especially older North American players, don't fully support MPEG1, Layer2 audio, and this could well be what is causing your sync problems. I've run across this problem before on a couple of (rare) occasions...The only answer there is to either re-encode your original MPEGS's using a different audio format (Remember though, TDA cannot handle AC3 streams so it HAS to be MPEG1 LAyer2 or Linear PCM format) or get a DVD player that can handle the format.

Hope that helps

kewl!!!

i've so many advices, i think i will have some work to do this weekend hehe

thanks for the support guys

i'll let u tomorrow

this is very interesting, i'll give it a try after lunch hehe

Killerfabber,
What was the outcome of all this?
