Importing from a DVD drive question

NathanAyres wrote on 1/16/2012, 3:41 PM
I am using Vegas Movie Studio HD Platinum 10.0. When importing a DVD from my DVD drive using "Import DVD Camcorder Disc" and then dragging it into my project and then go to the end, I see a gap between the video and audio. Why is that? When I import the same DVD with another program I have and then drag it into the project, there is no gap.
Could somebody explain to me how to import a DVD using Vegas Studio and drag it into my project without the gap at the end?

Thanks for anybody's help
Nathan

Your suggestion doesn't work for Vegas Movie Studio. It only works for Vegas.

Thanks Anyway.

What i like best is to use the DOS copy command. Copy the .vob files to your hard drive, then in a DOS command window, CD into the directory with the files, and type in something like this:

copy /b VTS_01_1.VOB + VTS_01_2.VOB + VTS_01_03.VOB video.mpg

and press Enter. This will concatenate the three VOB files together into one .mpg file which Vegas Studio will open up without a hitch. It can take a while though so be patient.

So then there isn't any clean way to import dvd's to where the video track isn't longer than the audio track? I have version 10. Does version 11 add the ability to import cleanly?

Also thanks for all the help so far.

Thanks

Thanks. Got it. Below is an image showing what happens when I bring an mpg into my project in vegas movie studio. Why is the audio shorter than the video? This always happens. When I bring it into the project, the program generates a sfk files. Does that change the audio? I have gone into the preferences and can't find anything that will keep that from happening. I have version 10. Does version 11 correct this?

If your DVD is unencrypted or decrypted, VideoRedo Plus is your friend.

EDIT:
"Your suggestion doesn't work for Vegas Movie Studio. It only works for Vegas."
I don't know what you mean by that statement. I have installed VMS Platinum HD 11 trial version on my computer, and the Gary James method works perfectly!

Thanks Anyway.
;?)

Thanks for your response. I have version 10 and when I tried it, it didn't work. So I made an assumption it would only work in Vegas. I have now up graded to 11 and it works fine.

Ok so I import the IFO file. I would like to learn here though. If it isn't too technical, why is there a gap at the end of the track between the audio and video as shown below when importing from a DVD. Opening of the IFO file just seems to be a work around to me. Is there a setting in preferences to stop this? Is it the audio format of the DVD like if the audio format when importing is AC3, does that make a difference. I don't think I have seen a reason for this after searching the messages.



Thanks for any help ahead of time>

It's a little hard to tell the scan in your image, but i think the blue dots at the bottom of the video track are frames, right? That means the audio is about 6 frame shorter. This is usual and normal. Due to the varying timing between video frame rate, GOP structure, audio sample rate, and interleaving block sizes, when an MPEG file is split into separate VOB files the lengths are not going to match. A normal playback device such as a DVD player is able to handle this by knowing that the last bit of audio will be in the next VOB file and fetches and plays it without interruption. Vegas doesn't handle this well. It doesn't understand the continuity between the VOB files and leaves the gap.

As far as using the IFO file being a workaround ... so what? It isn't really. Not only is it exactly as valid an import method as anything else (you still end up with the identical MPEG file on the timeline), it actually works, unlike other methods. So, if it works, and not only works but works better than other methods, and is faster and easier, what's the problem with using it?

Is this really a "problem"?

Yes, it would be nice not to happen .. but .. how often do you need those few frames? You really should not be shutting off your camcorder untill a few seconds *after* everything you wanted to tape is finished. (by the same token you, if possible, you should start taping a few seconds *before* the action starts)

Well, the problem is that it happens whenever there's a VOB break, which might just happen to be inside a scene.

I had understood from previous posts that this method dealt with the problem at VOB boundaries. If it doesn't I would suggest using DVDShrink and setting it produce a single VOB. Even better, TSMuxeR will do the job much more quickly.

Well there are other programs I have used for importing from DVD that don't do this. So my logic is that if other programs can why not Vegas. The videos I have been importing have several chapters. When Vegas imported the chapters separately instead as one and I put them in the project, there was an audio gap between them which of course won't work. So I have had to resort to using Movie Factory from Corel to import. I just wanted to be able to do this all from within the program. Trying to transition to Sony stuff. Now if this is expected from Vegas and will be normal, then it should be in some chapter in help file that if you are importing from a DVD with chapters you need to import the Video_TS folder and open the IFO file. Other people considered it a problem until Gary James chimed in and showed everybody how to work around this. Nobody knew according to the post I read until he spoke up. Anyway I am a curious type and been a troubleshooter most of my life and the troubleshooter in me just wanted to know.

Thanks for all the responses though. :-)
