Quality Difference Between avi/mpg for 2 cam-mix??

[Sneaksox]

I read a bunch of archived threads but couldn't find one adressing this exact issue, so any insight/advice would be very much appreciated.

I have two individual .mpg2 video files (a stagnant cam and a zoom cam) and a .wav matrix audio file for a live concert.

I was wondering if I can just make a two-cam mix in Vegas with the .mpg2 files, or if I should find/capture the original .avi files and use those for the mixing?? I realize there will be some difference in quality between the two options, but I was wondering what the difference will be?? Is it worth the time to track-down and re-capture the DV tapes again??

Thanks in advance for any help/advice

yes it's worth the time to track down the masters.... when you combine the two angles you will have to rerender the files which will introduce artifacts..... THe effects will be fast moving objects will studder and there will be other weird things.

Cool, thanks for the info. It won't be too hard to track down the DV's so I will do that ASAP.
