VOB MPEG2 files behave strangely on the timeline?

Is it me, or do VOB MPEG2 files from DVDs behave strangely on the timeline? Can't quite understand what's going on. I'll play something, then go back and play it again, and where there should be a fade in fade out, it's not there, but then if I change the preview quality to something else, then it fixes itself. Or things will flash, just a lot of odd behavior. Is that normal?

There's only two IFO files for this DVD:

VIDEO_TS.IFO 64kb
VTS_01_0.IFO 160kb

I think that was the problem with your DVD authoring program. It did not create a valid DVD.

I agree, JackW would probably disagree with you. Funny thing is, the DVDs have been sold since 2004 and no problems with them, go figure.....

Jack is right. From your description, this DVD was authored in a non-standard manner. Almost universally a DVD's main title is the first physically placed video asset on the disk. On your disk they placed the intro and main title in the same VTS (allowed, but not common), and layed out the Intro video as the first physical title. This is why Vegas only see's the Intro and not the movie.

That explains the first problem, but not the other. I believe that DVDShink uncovered an error on your disk that may be at the root of the second problem - odd behavior in the timeline. Your other DVD utility is probably seeing the same problem, but not stopping with a displayed error message. And it appears as though you have a good .mpg file, but don't.

Pretty strange stuff. I'm not sure of any of this. Only that DVD Decrypter successfully saved each chapter to a VOB file that I was then able to insert on the timeline and they play fine.

I'll say it again, "Try VideoReDo".

As the name suggests, it fixes up (re does) a video file to make it fully compliant.

PeterDuke, I don't need to fix the file. I've decided not to use dvdvob2mpg because it doesn't create files from each chapter. If I put one big MPG file on the timeline, then I have to go through and find the chapter points based on their time lengths. With DVD Decrypter, it creates a VOB file for each chapter, so all I need to do is select them all and drag them to the timeline and then I have an event for each chapter of the original DVD. Soo much easier and less time consuming.

Be careful Mike. The technique you describe can cause "hiccups" in the audio/video at the point where the files are joined in the Vegas timeline. If this is your approach, I suggest you pay very close attention to the continuity of your A/V stream at the joining of each VOB segment.

MikeLV wrote on 6/6/2016, 11:07 AM

I understand what you're saying, but the files aren't joined, they're separate events of each chapter and I haven't seen any hiccups thus far. Give it a try and see :-)

Gary James wrote on 6/6/2016, 12:58 PM

I meant joined in the Vegas timeline (i.e. butted up against each other).

PeterDuke wrote on 6/7/2016, 2:58 AM

If DVDDecrypter concatenates VOBs and parts of VOBs as necessary to make a single VOB file (actually an MPEG file) for each chapter then you are done. There should not be any hiccups. If the extension is VOB just rename it to MPG.

MikeLV wrote on 6/8/2016, 1:38 PM

Don't even see the need to rename to MPG as Vegas is accepting the VOB file without issue

Cool.

That doesn't work for me, already tried it. What I'm doing is using http://www.dvdvobtompg.com/ to first convert the VOB files to one long MPG file and then putting that on the timeline.

Thanks. Been having trouble for ages until I found this post.
