Out of Sync When Converting MPEG2 to .VOB

Post by julie199 »

Today was the first day I have experienced an out of sync problem with U-lead. I have read the other postings but have not found anyone having a problem like I had today. I have version 6.0 and went to convert the finished MPEG2 file to a file playable (.VOB file) on my stand alone DVD player. When I finished making what I now will call my coaster the DVD played perfectly in my DVD player but the voice was out-of-sync. I went back to my computer and played the MPEG2 file and the voice was not out of sync on that file. What happened to the DVD I burned? It seems when the MPEG2 file was converted to play on a DVD player something got out of sync. This is the first time this has happened to me. I am just a beginner so I imagine I have not explained myself very well. I will try to explain myself better if needed. Thanks ahead of time.

I have only had that happen to me once and here is how I fixed it. First I ran a cleaning type program on the computer to get rid of all the garbage files, temp files etc. If you are using windows then just use disk clean if you have nothing else. Then I did a defrag of the hard drive to make sure eveything was nice and tidy. Then before doing the burn I made sure that any background service that was running was shut down, things like internet connections, sofware like virus scanners etc, anything that could spring to life whilst the program was doing its DVD thing. Only then did I do the burn. I found that doing these things at the file creation stage also made things faster and more certain of success.

Thank-you Lancecarr for your reply. I will try all of your recommendations and let you know what happens. This is a very large project and I hope that I do not have to start from square one again.

One option that I knows works very well and avoid the OOS problem is to create an ISO from the VIDEO_TS folder you already have using ImgTool Classic, and then burning the ISO file to a blank disk using the program of your choice.

The OOS seems to be caused by Ulead's multiplexer.

ImgTool Classic

Thoff,

I downloaded the program you suggested but there was one problem. My VIDEO_TS file is nearly 2 gig long and when I converted it with ImgTool Classic it blew out at 4.3 gig with only 77% done. The file nearly doubled in size during conversion and I could not finish it. Am I doing something wrong or is my file too big to use the program you suggested?

Thanks Julie199

Julie,
Have you tried remaking the project video file with Smart Render off?

Julie199, I think what happened to you is that you pointed ImgTool to a location that contained more than a VIDEO_TS folder, such as the CONVERT folder that UVS creates during the DVD encoding. If that's the case, ImgTool would have included the extra files in the ISO image it creates, and this could have blown the 4.7GB size limit.

I would temporarily move the VIDEO_TS folder to another location that has no other files or folders in it, and then use that as the source for ImgTool. Please be aware that ImgTool will create a new, empty AUDIO_TS folder for maximum compatibility with standalone DVD players -- this is normal.

I had a similar problem. My conclusion was that the MPEG file is somehow corrupted. It will play OK with Windows Media Player, but, when you try to make a DVD, Video Studio (or DVD Workshop) can't handle the corruption.

In my case, the apparent corruption was caused by editing (with transitions & crossfades) MPEG files with Video Studio. A DVD made with the same, but un-edited, source file was OK. (MPEG files are not supposed to be edited.)

I assume that this happens during de-multiplexing & re-multiplexing. As long as the file is multiplexed, the audio & video can't get out of sync.... evin if the file is corrupted. When the audio & video are split apart, one might get it's timing fouled-up independently of the other.

I found a work-around... saving each trimmed-clip to a separate file. Similar to this.

Then, I bought a special-purpose MPEG editor. :)

Julie,
The audio problem can be caused by more than 1 issue which makes
it quite hard to repair or find.

Have you made any updates to the version 6.0 program like applying
the cd/dvd burning patch or engine updates.
If so, maybe re-installing the original version and the updates that
apply to version 6.0 only may restore the system.
Stay away from any burner engine updates unless ulead tech support
advises to do so.

If you can use another program to burn the mpeg2 file without re-encoding
the mpeg2 file that will tell you if the mpeg2 file is the problem or not.
Use another program besides any ulead program because they all share
the same burning (DVD) folder modules.

Hope this helps,

MD
