Editing DVD Ripped Content = Sync Issues

gordonmcdowell wrote on 1/24/2010, 10:30 AM
I have used DVDFab to retrieve VIDEO_TS files from a DVD which could then be successfully imported into SONY VEGAS PRO 9.0.

This (as you'd expect) creates MPEG-2 data files from the VOB data.

The multiple audio channels are retained. Everything looks proper.

But when I begin editing with the MPEG-2 files which created during the import from VIDEO_TS folder, I have sync issues and the picture stutters.

First off, I'd certainly appreciate instructions on whatever it is I'm missing here. Since all media players can play the MPEG-2 files, I'd hope SONY VEGAS would be capable of editing with them.

But aside from any advice on that, why does SONY VEGAS insist on using its own MPEG-2 and MPEG-4 decoders. There's open source MPEG decoders which offer broader support for codecs when used by VLC Media Player and the like... and these tools can be used to decode unrecognized codecs like M-JPEG. Isn't there a way of letting VEGAS use a 3rd party MPEG decoder? I mean open source tools leveraging these decoders can play VOBs, never mind having to import to MPEG.

Also, please expand your video rendering options.
- MainConcept MP4 using iPod settings does not result in a video which can be skipped through on my iPhone.
- MainConcept MP4 limits the RGB range.
- SONY AVC MP4 is CBR only.
- SONY AVCHD is interlaced only and CBR only.

How about rendering to FLV? OGG Theora? An H.264 setting clearly defined as save for Safari & Chrome's HTML5 support?

Thanks for any help on this. -Gord

Just a headsup, we have an informal agreement here not to discuss RRR.
Sony's dvd import works best with camcorder discs. You may find VideoReDo to your liking for other sources.

I don't know what RRR is, but since people here make their living delivering video, they don't want to support "ripping" (off) copyrighted material. So, I assume that is what musicvid is referring to.

If you are attempting to copy or edit copyrighted material, you won't get help in these forums.

That said, I have posted many times before on how to overcome the problems of editing VOB from DVDs that you created or which you have the legal rights to edit. The first thing to try is the camcorder import feature, as already suggested.

If that fails, the next best way is to use DVD Shrink. You use this NOT to "rip" a DVD you don't have the rights to copy, but to join together VOB segments in a way that avoids audio gaps and, in some cases, the A/V sync problems. I describe that here:

Audio gaps in imported DVD files

The "ultimate" solution to the problem is far more complicated, and I describe it here:

Frustration extracting DVD files

If you read through my other posts in that thread, you'll find some useful links, including a link to a very, very crude tutorial on how to actually do what I describe in the link.

RRR = "Rent, Rip, and Return"
Innocence is bliss.

I always thought RRR was Reduce, Reuse, Recycle.
Guess I'm showing my age :-)

You are both correct, although in previous decades . . .

johnmeyer,

Thanks for the direction. I did use a virtual frameserver at one point years ago, but in this case I'm looking to pull from 15 DVDs and the frame sever I used at the time (it worked with AVISynth) limited me to ~10 simultaneous imports. I'm not sure if it was AVISynth which had that limitation or some other component.

In fact, all the MPEG-2 files created by importing the 15 DVDs (not using virtual frame server) can't be simultaneously supported by Vegas. That's ~150 MPEG-2 files. I don't know what the fail exactly is... but I'm going to assume a virtual frame server is not a workable approach for >10 DVDs (but I'll check it out for projects using fewer).

Switching to 64-bit Vegas has helped me with many rendering errors, and reduced the crashing when editing with very complex projects. But importing lots of media of certain types (Aiptek camera footage H.264 and DVD sourced MPEG-2) seems to hit some upper limit and simply crashes when importing too much of it. There's no one file which fails... I can successfully import every file, just not most of them in one project.

I'll also check out VideoReDo, maybe it has import utilities which create MPEG-2 files Vegas can handle. I really don't want to edit in anything less useful than Vegas.

DVD Shrink looks promising as well.

Thanks folks & johnmeyer,

And is it possible to subscribe to these message threads so I get an email when someone posts a response? I don't see where I can enable that.

Sorry Gord but, despite repeated requests, that's not an option on this forum.

I've used CloneDVD Mobile from SlySoft to convert DVDs that we have been authorization for, into editable AVI files that I use to produce a much smaller Flash web version.

CloneDVD Mobile will produce one continuous AVI file from a multi-VOB DVD video.

Audio out of sync comes in two flavors, constant and progressively wider. Constant can be fixed easily with AVIdemux. Just copy both streams and use a best guess in the millisecond box. - or + .

You can stop the job after 10 minutes or so and test the partial file created.

Progressively worse OOS I dunno.
