audio out of sync

[maesstro]

Captured some footage from DV camera into Ulead Media Studio Pro 7; edited it and got mpeg that worked just fine; imported into Ulead DVD Workshop 2, chopped it into chapters, added menus and previewed the whole project - still all worked fine; got to the stage of converting the project to DVD files - regardless of what template I chose (high quality, standard quality, 60 min per DVD etc.) the "required disc space" tab showed the same value - peculiar; nevertheless, proceeded with creation of DVD files and ended up with a project where audio is out of sync (the first 40 minutes are fine, but the rest 60 min. have audio about 1 sec. before video). Tried various templates, but always ended up with the same result. Furthermore, file sizes were identical regardless of the template I used. Tried defragmenting the drive - same thing. Thaught it was a DVD Workshop issue, so authered DVD with DVDLab. Same thing and it's really driving me nuts!
It shouldn't be a hardware issue, cause I authored few DVDs without any problems before formatting the drive a couple of weeks ago. After formatting I installed XP + SP2 (before I only had XP). Could it be the driver issue and icompatibility with SP2? What hardware drivers should I concentrate on? If not, what else could it Be? Any ideas?

sounds like there's a damaged segment of your video.
Can you load the mpeg into VirtualDubMod and run 'check for errors'?

[maesstro]

I'll try the VirtualDubMod, but I doubt that it will solve the problem 'cause the mpeg file (after editing and before DVD authoring) works fine with Windows MP 10. The authored project is also syncronised in DVD WS preview. The problems arise when it comes to burning the whole project in DVD format.
Forgot to mention in the original post that demultiplexing video and audio didn't help either.

A quote from your initial post:

"imported into Ulead DVD Workshop 2, chopped it into chapters"

This might be the root of your sync issue. As an experiment, "Burn" an "Uncut" version of the Mpeg file and check if it is in sync.

[maesstro]

Tried it already - put the whole 5 GB video as one chapter. Ended up with the same results.

"Tried it already - put the whole 5 GB video as one chapter."

You could not have "Burned" a 5 Gig video onto a standard DVD 4.7 Gig (r, rw) disk. Did you use DVD Shrink or similar to compress?

So, in one piece it was ok for 40 minutes then video jumps one second back? sounds like an error to me. VDubMod does offer an option to fix it but I'd save output as a new file.

ormonde - I didn't actually burn it to DVD, but converted it to DVD output (VIDEO_TS folder) on the hard disk and played the video on Power DVD. I would have shrunk it afterwards if everything was OK. I use dvd2one.

sfheath - if the mpeg were faulty it would have shown in Windows Media Player. And the most frustrating thing of all is that after authoring the whole project everything works perfectly fine in the preview mode of DVD WS, but when it comes to converting to DVD format the problems arise.

"I didn't actually burn it to DVD, but converted it to DVD output"

It appears that something is happening in the "Conversion" process from mpeg to DVD. As an alternative, try this procedure:

1. Convert the AVI (DivX or Xvid)/mpeg file(s) to a DVD compliant mpeg-2 file(s) using "TMPGEnc" or "TMPGEnc Plus". Use the DVD template (NTSC or PAL) form the "Project Wizard" to help you accomplish the task. If you have an mpeg file that is already DVD-compliant, then skip directly to step 2.

2. Then use "TMPGEnc DVD Author" (different than "TMPGEnc") to author the newly created mpeg-2 into a DVD-related file structure (.IFO, .BUP, .VOB). As an alternative, you can use "DVDLab" to author as well.

3. If the combined filesize of the project exceeds 4.37 Gig, use "DVD Shrink" or similar transcoding program to compress.

4. Use "Nero" or similar burning program to burn onto a DVD (r, rw) disk

[sfheath]

Windows Media Player isn't actually that good for testing DVD compatibility. Far better to use WinDVD/PowerDVD.

BTW, if you try TMPGEnc DVD Author it has it's own rather nifty little DVD burner app.

"the first 40 minutes are fine, but the rest 60 min. have audio about 1 sec. before video"


You can resynch the MPEG file as follows:

1) Load it into TMPGEnc

2) Set mode to "MPEG-2 Program (VBR)"

3) From under the "Advanced" tab, put a checkmark next to and then double click on "Source Range"

4) Set start and end points (to the start of the oot of synch portion and the end)

4) Enter an appropriate positive or negative amount of milleseconds (thousandths of a second) next to "Audio gap correct"

5) Save with a new filename

Let us know of your success ;>}

First of all - thank you guys for your replies.
Video that came out of MSP: 5,3 GB mpeg/48 kHz/8000 kbps VBR - checked it with VirtualDubMod and everything is in sync and working properly.
As I said - DVD authoring with DVD Workshop worked properly before I formatted the hard drive. I really don't think that it's a software issue 'cause DVDLab and TMPGEnc DVD Author come out with the same "out of sync" result.
I must be missing some driver update, so I'll check for newer versions (although no confliczs reported in the device manager).
Could SP2 for Win XP be the cause of this?
And by the way - I noticed that my ASPI drivers weren't installed properly, so I reinstalled them and thought that it would solve the problem - but it didn't. Could I be missing some driver and/or engine that's not directly hardware related?

If this was so I don't think your first 40 minutes would be in sync.
Did you try VDubMods 'check for errors' or Setarips 'source range' fix?

[maesstro]

Come to think of it - it could be that in the first 40 min. the "out of sync" is unnoticable (but present), and then gradually increasing to more than 1 sec difference towards the end of the video.
I'm only talking about the DVD files. The mpeg file (which is the source file for DVD authoring) is in perfect shape and verified with VDubMods 'check for errors'.

[sfheath]

I'm definitely on shaky ground here but I think I'd rerun your file as Constant Bitrate
