DVD Lab Pro Audo-Video Sync problem?

[SerbianBoss]

Hello to everybody,

Namely y have interesting problem.Y capture my old vhs casette in mpeg2 format. Captured video have good picture and audio video sync is OK. But when y import that mpeg2 file in DVD LAb pro y choose option demultiplex to elementary streams.And says Video is 1:30:20 ana audio is 1:30:19. And when y author dvd y have a little audio video sync problem with one second.

What is problem? Original mpeg video file is ok, but when y author dvd i n dvd lab pro 1.5 y have audi video sync problem with one second.

Both options demultiplex to elementary streams and quick mode without demultiplexing dont help.Always have a little audio video sync

thanks

Is it out of sync by the same amount all the way through, or does it drift out over time ?

If the difference is constant, use the delay correction in DVD Lab Pro to shift the audio back into sync.

DVD Lab is known not to produce 100% compatible DVDs. I wouldn't trust DVD Lab and wouldn't use it to author DVDs, but YMMV.

[SerbianBoss]

My film has 2 hour.After one hour y have that problem(audio video sync).

How can y use in dvd lab pro delay correction?

[guns1inger]

You can't for your problem. I suspect some form of corruption for it to suddenly slip out of sync. Are you sure the original doesn't do this ?

spectroelectro - what would you recommend instead, that can guarantee 100% compatible and compliant disks ?

Original file is ok.No audio video sync in original file, but when y put in dvd lab pro y have a audio video sync.

Can anybody recommended a goog authoring program like DVD lab pro or sony architect?

tnx

I had problems with DVD-Lab similar to those you describe. In addition to the audio sync problems, I also couldn't seem to find a way to set chapter points that didn't drift away from the original, pre-set time code as the video went deeper and deeper. Those who frequent this forum who swear by DVD-Lab will suggest these causes were my fault and I would not disagree. I just couldn't find a way to resolve them in a manner that justified purchasing the program. So, like you, I began to look for other authoring solutions.

In DVD-Lab, I found I could effectively deal with the audio sync problem by compiling in the Alternative (relaxed compliancy) mode. I didn't exactly like using this mode, but it seemed to work in resolving the sync issues. You may want to give that a try before you go looking to spend more money on another authoring program.

If you do want to consider another authoring program, I would recommend TMPGEnc DVD Author. I tried this program when I couldn't resolve the chapter point issues with DVD-Lab and have been very happy with it. There is a 30-day trial available.

There's another program I wouldn't be without that you might want to also consider. VideoReDo
offers a "Quick Stream Fix" (QSF) feature that, among other things, can resolve many audio/video sync issues. I found VideoReDo was also faster in separating the MPEG into its necessary elementary streams for insertion into DVD-Lab than was DVD-Lab.

What is in dvd lab relax compliancy?Where is that option?Maybe help me that option for audio video sync.

Y try tmpgenc dvd author but y have the same problem audiov video sync.

Ulead movie factory work best for me, no audio video sync problem, but ulead is very easy(no advanced making menu).

tnx

dvdlab is not for those who do not understand the complexities of authoring....the chapter issues are encoding issues....you need to use GOP of 15 in NTSC with a closed GOP for chapter pts. to work well....audio sync is invariably a problem caused by a poor capture or poor encode (or poor burn/media)

I have tried DVDlab authored stuff of over 70 players (73 to be exact). No it is no Ulead...but Ulead is wzard based.

never capture directly to MPEG...in DVDlab since you demuxed goto Tools--Rewrite GOP time code.

not 100% Phillips DVD verifier failes Sonic Scenarist projects often BTW...compliancy means nothing

Y have good TV card with hardware mpeg2.
100% audio and video is ok.But when y put in dvd lab pro y have audio video sync.

Again,can anybody recommended a goog authoring program like DVD lab pro or sony architect?

[jberry]

my guess is that your tuner card is not making DVD compliant streams....DVDLab does not like non compliant streams...I bet if you capture to avi then encode to DVD that all will be fine. I see soooo many people trying to capture to mpeg2 directly from these tv cards that always have problems....I did too, so I sold it and got and advc100....in my opinion you are wasting your time with tv card mpeg2 encoders...so many forums filled with people with issues like yours

If you'll try this link it should take you to the DVD-Lab tutorial. Scroll about half way down the page until you see the section on the Multiplex Engine. There you'll see an image that shows the Alternative (relaxed compliancy) option and how to select it.

Ulead movie factory work best for me, no audio video sync problem, but ulead is very easy(no advanced making menu).

Just what is it you're attempting to do (what menus do you want to create) that you feel can't be done in Ulead Movie Factory? (I'm not saying what you want to do can be done in Movie Factory. I'm just tryng to understand what you want to do.)

Y want to make advanced menu for dvd.For example: panoramic menu, switched menu, or film strip menu.In dvd lab that is possible, in ulead not.
Sony architect is good, but sony work best with progressive files.

Y try to fing authoring program(s) who work with interlaced files without recompression.A program who can make advanced menu like(architect or dvd lab)

[jberry]

who told you vegas is progressive only...does interlaced fine

[SerbianBoss]

not vegas, y said dvd architect.

[canadateck]

Ulead DVD Workshop can do switched menu's.
