Different video qualities and sizes possible?

Hi folks,

When I burn my current project I have the source MPEG2 file and DVDA set to the highest quality and it all looks fine. But I also plan to add some "Making Of" footage to this DVD which will be fairly long and does not need to be as high quality. DVDA has a single Quality setting for the entire DVD. If I render each Making Of section from Vegas as a lower bit rate MPEG2 than the important parts, will DVDA retain the smaller file sizes or will it inflate those sections and increase the bit rate to match the rest of the DVD?

Yes, I know I could just try this and find out. :->) But the video sections are long and I figured someone here will have a ready answer for how to incorporate different video qualities / sizes onto a single DVD.

Thanks!

I think that the answer lies in specifying in the Optimise dialogue that you don't want the 'making of' footage recompressed.

Excellent, thanks Mike! I missed that part of the dialog completely.

Usually you'll render your mpg2 beforehand, then just double check the optimize dialog to make sure it won't be re-encoded -- 99.9% of the time it won't if your mpg2 is DVD spec. If because of menus etc. you happen to go over the size limit, DVD Shrink or Recode can selectively reduce the size of just your "Making of" video, though there will be a (hopefully very small) quality hit.
