Audio sync issue...

My experiences were a little different this weekend (fully patched and using PAL).

When rendering the mpeg I have to switch off 'Smart Rendering' to stop the audio in my transitions getting messed up.

At this stage, playing the mpeg in WMP or anything else, results in bad lip sync. However, after creating a new 'Burn' project, and adding the mpeg, the final DVD has perfect lip sync!

I tried two burning methods...

1. Using UVS8 - the DVD played fine from my PC's DVD drive, but developed an audio/visual judder, about two minutes in, when played on my Panasonic E50. Not sure yet whether it's the software, my settings, or just a bad disc.

2. Using DVD Decrypter - the DVD played fine on my PC DVD drive and also on the Panny.

It's only a 4 minute video, but my confidence has been restored by the perfect lip sync in the final DVD. I've yet to see how this holds out in a longer video.

stephen,

The problem may have something to do with the patches after all. In my efforts to fix my OOS problem, I first tried what you did - uninstalling and installing without any patches. Then, I repatched and tried again and I thought it was my method that fixed it. However, what I failed to do was to put on the burning engine update and the 16x patch. One of these may be the patch that causes the problem. Please try it with only the update patch and let me know.

I'm not keen to start putting patches on again at the moment :?

I want to spend a bit of time working without the patches (what were they supposed to do anyway??)

Also, I won't have much free time over the next couple of weeks because of work committments.

I did ask Ulead for technical help with this issue but I had no response - a little dissapointing.

Good luck with your editing!

Stephen,

Stay with the original installation version 8.
The update causes the out-of-sync problem in the mpeg2
file when cutting into the mpeg2 stream.
Smart render On/Off doesn't matter.

MD,

Many thanks for this. I will try using Smart render again - it takes such a long time without it!

:)

PS - I did get a response from Ulead technical help:

Uninstall, reinstall, apply patch, update direct x, defrag hard drive, blah blah blah!!!!! I guess Ulead have not figured out the problem.

Steve,

Please email me.
Will tell you what I've learned.
I shouldn't post what I've learned, that could cause someone else's system
to crash. Don't want to do that to anyone.

I recorded a 8.5 gig file at 6000vbr (no frames dropped)
Multi-Trimmed chopping the heck out of it (many cuts)
Created a 4.5 gig file (smart rendered it)
Burn the VIDEO_TS folder using another program.
Plays in sync.
One point, depending on the file versions in the DVD creation
directory ulead will try to correct the sync problem with the Mpeg2 file.
That's why I use an external burning program.

On my system the bug only appears when you cut into the Mpeg2 stream.
I could merge files together no problem (smart render).
That is after applying the updates.

At least this is progress. It defines 2 bugs.

Ulead must be working on this but I suspect it's not an easy fix.
Mainly because the files in the DVD directory affect ALL unlead products.
If your source files are compliant the files in the DVD directory that support
dual-layer burning work.

I think the way Ulead released MF3 they have new programmer(s), or
someone valuable retired or left. Not easy to go through 300,000 lines
of code that someone else has written.
But that's their job. Still should never release a program without throughly
beta-testing it first.

Editing Mpg's isn't the way to go but the software industry must do it
because of all the new devices on the market (dvd camcorders/USB etc).

I too had audio sync problems with VS8. It was a give-away with my panasonic dvd burner.

The problem was that the editing worked fine and there were no sync problems with the project or original footage. Then, once burned onto DVD, it replayed with the audio out of sync with the video by a second or so.

I did some Googling around (but since lost the relevant address) and followed one guy's suggestions which worked:

1. Edit footage as normal.

2. Save project to a file.

3. Use create DVD on that file but in the options de-select the "Use Smart Render" box.

What I concluded was that this is the only way to switch off "smart render" which seems to be the program causing the sync problem.

For me, problem solved, hope so for others.

Other than that, its been relatively easy to use the program as long as you are happy to learn by trial and error since the handbook is not very detailed.

Cheers

Hi All

I have done several tests trying to find a cause for the out of sync’ audio.

From the tests I think the combination of the ‘Update Patch’ and using ‘Smart Render’ is the problem, but I still have more tests to do, now my holidays are over I will start again.

When I use VS 8 without the Patch I do not get sync trouble, with the Patch and after using Smart Render I run into problems. Smart Render appears to corrupt the file.
BUT !!!
The rendered Mpeg looks ok and can be played on my pc (windows media player, power dvd, real player etc) and shows no signs of sync problems, the out of sync occurs after using the file in the burner module.

This makes it difficult to identify any problem files, as the fault only occurs in the last stage.
To test my theory you would have to start with a new Mpeg that has not under-gone smart render, or use VS 8 without the patch.

After uninstalling VS 8 I also deletes all additional VS 8 files, this cleared my pc of all vs8 related files, I then reinstalled VS 8 only.
The resultant mpegs are now ok.

Its about time Ulead tech support sorted this problem

If you haven't already reported the out of sync' problem to ulead, then do it now.

I reported the OOS problem to Ulead back in November and they acknowledged they were aware of the problem then. As you say, UVS8 creates MPEG's fine so the problem is in the "burning" phase (it happens even if you create your output files to disk and don't actually burn them).

IMO, Smart Render is a red herring.

I fixed the problem by regressing the files in:

C:\Program Files\Common Files\Ulead Systems\DVD

Either Ulead doesn't care about fixing this, or they don't know how to fix it...

VS8 Out of sync audio

Post by Bernie »

Here is a way I stumbled across to correct out of synchronism audio in VideoStuio 8 (VS8) with all patches installed. My experience is based on capturing via WinFast 2000 XP Expert WDM video capture card using the standard DVD capture profile of MPEG-2 codec, 720 x 576, 6000 Kbps, 25 fps.

Note that once the video is captured it is advisable not to change the project properties away from the original capture settings as this can be the cause of out of sync audio. There seems to some threshold of project length, number of scenes or scene length that triggers out of sync audio but I have not been able to figure out what it is. If out of sync audio occurs in the final DVD I have been able to correct it by the following procedure. I don’t know why it works but it has for me.

1. Render the whole project to an MPG file via Share, Create Video File, Same as Project Settings. The new MPG file will show up as a thumbnail to the right of the screen when it is done.

2. Open a new project and drag the new MPG file into it.

3. Divide the new MPG file into equal segments of about 25 minutes. MUST BE LESS THAN 30 MINUTES. Select the new MPG file as a clip, mark out at a scene change at the end of the first 25 minute or less segment then render to another MPG file via Share, Create Video File, Same as Project Settings. Note the mark out point. Name this file Part 1. Drag the mark out point to the end of the clip, make the mark in point one frame past the last mark out point and make the mark out point at a scene change at the end of the next segment. Render to another MPG file via Share, Create Video File, Same as Project Settings. Note the mark out point. Name this file Part 2. Repeat for part 3 if required. This new project does not need to be saved.

4. Open another new project and drag the two or three newly created MPG files into it then render in the normal fashion via Share, Create Disc.

I usually check the finished project on a rewritable DVD before doing the final burn as this can often save wasting disks if the outcome is not quite perfect.

Another solution to OOS problem

Post by s.burnley »

Althoug I posted this many weeks ago, it might be worth repeating it here...

I found that the OOS occurred as a result of performing the render to Mpeg from the edited AVI.

Incidentally I have tried Adober Premier Elements and even a copy of Adobe Premier but they too gave me OOS problems - very disappointing.

My solution however is to use TMPGenc Plus. I capture and edit in AVI. When I have finished my editing I create a new AVI file of the finished project. This is used as the input to TMPGenc Plus and rendered. You can do single pass CBR or double pass VBR to achieve whatever level of quality you need. It takes a loooong time - so I usually set it up to run overnight.

At the end however, I have a completely in synch mpeg file. I then bring this back into UVS8 using the create disk option, add chapter headings etc. This works fine.

Then I create a disk image SO file, burn it to a DVDRW and then to the final DVD if it's Ok. So far I have had no problems at all with this method.

It is affecting everyone. Ulead has not taken this problem seriously. They must be made aware that the entire user community is frustrated and fed up with their lack of response.

Everyone on this forum must file complaints with Ulead Tech Support AND with Ulead Customer Support!
For over a year I have tried many, MANY ways, using many capture programs...Pinnaclesys' Studio 9, several Demos of touted programs and now... MSP9 to capture ANALOG VHS tape. NONE will do it without the damnable OOS progressive LAGGING of the audio. DIGITAL source from a DVD... Fine, no OOS.

I am using the Pinnaclesy's capture card.... lots of HD space and plenty of horsepower "under the hood" of my computer and a new VCR/DVD player/recorder for source.

There is no way and no days that I can capture analog source with audio locked to the video!

This is a universal problem that should surely be addressed by the industry at large. Until further signs of advancement on this problem is indicated, I am giving it up!

It seems strange that the stand-alone VCR/DVD recorder can copy an analog VHS tape to DVD with NO LAG of audio... Yet, NONE of these computer programs can!

:evil: :evil:

Hi

Do you have a Digital Cam-corder that will support ‘throughput’

That is to connect your VHS tape to the cameras A/V-in. then connect the cameras Dv-out to the PC via firewire (I-Link)

Capture to Dv-Avi

I agree. The situation is ridiculous! Especially when you consider that the audio and video are multiplexed (interwoven) together in one file (with most video file-formats). There ought to be no-way to get them out of freekin’ sync! And, in fact, the problems I had showed-up only after re-multiplexing…

Yet, NONE of these computer programs can!
Many people (including me) are able to capture and convert analog to digital without sync problems.


I don’t recommend this, because it uses MPEG capture and editing… But, here’s what works for me:

Capture with my Hauppauge card and the special software that came with it. (The Hauppauge card is MPEG only).

Edit with Womble (A special-purpose MPEG editor).

Author & burn a DVD with Movie Factory or DVD Workshop.

WORKS EVERY TIME !!!

Hmmm,sounds like my work flow :wink:

I ,too, use a Hauppauge (250) card AND the WinTV 2000 software to capture both "off-the-air" and from my venerable Sony Hi8 camcorder.

Basic (cut and/or delete) editing is done with VideoReDo (another special purpose MPEG editor).

Fancy editing is done with VS9 (fades, transistions, titles, special effects, music etc.)

Authour and burn with MF3.

WORKS EVERY TIME !!! No sync problems, no hang-ups, no problems of any kind.

One of these days, I'll be having to update my late 90s technology, but, in the meantime....
