24fps .mpg rendering longer than it should
Using Magic DVD Ripper, I created an .mpg of the movie Zardoz, using the “original stream copy” setting. It results in a file that most programs recognize as being 23.976 fps.
I imported the file into a Vegas program using the “use video settings” option and got a timeline that said the same thing.
We then proceeded to use Vegas to record a commentary track a la RiffTrax, in real time, so that when you play the project back in Vegas, the timing is correct.
Upon rendering the project, the timing between the video and the commentary becomes problematic. It seems that the video somehow becomes… longer, by only fractions or frames, so that the further into the project it gets, the more out of synch the audio tracks become. The anomaly is that the closer the movie gets to the end, the more ahead the commentary track becomes, to the point where our jokes are just a little too far ahead of where they should be.
Can anyone shed some light on this? We are rendering the video as both uncompressed .avi and NTSC 24fps DVD mpeg, both with the same results.

Your problem arises from ripping the DVD with your Magic DVD Ripper,
and placing it in Vegas. Vegas is not to be blamed.
Why don’t you just use Vegas to rip your DVD and have everything
automatically ready to go on the timeline.Steve Rhoden

Vegas probably won’t ‘rip’ the DVD as Steve suggested because it is most likely to be copy protected. This forum does not tolerate or condone piracy of software and other copyrighted material, including commercial DVD’s such as Zardoz. You are going to have to seek advice elsewhere.
The timing issue is most likely being introduced during the render as caused by the source footage.

Interesting. I didn’t know Vegas had a ripping function at all. I’ll give it a whirl and see if it works.
I can understand your concern, but the DVD isn’t being ripped for distribution purposes; we have to have the original .mpg stream on file so that we can record our commentary track in real time. We’re only rendering out the first thirty minutes of the film for uploading to YouTube for preview purposes, which is protected by the Fair Use doctrine, which puts certain limitations on copyright in situations where the material is used for commentary and/or criticism. What we’re doing is legal.

Apologies for my blunt approach earlier. We have had a few ‘users’ seeking assistance in piracy of either SVP or content copying.

No worries.
I seem to have gotten around the problem by dropping the .mpg into Vegas and re-rendering as a DVD .mpg with the same settings. It stretched the video out to its proper length, and then I was able to record a commentary track over top of it. Not sure why, but it worked.
