Slow render in DVDa2

I have a 2.5 hr video made from a vhs tape going to dvd. Real basic just old 16mm footage put onto vhs now dvd so extreme quality was not the concern. Anyway I rendered the 2.5 hr file in vegas 5.0 to mpeg 2 and the file was 4.53gig. DVDa2 says its to big so I used the optimize dvd and changed the bit rate to 3.5bps. My question is in vegas it took 4 hrs to render to mpeg 2 and 11 hrs to re render in dvda2 just to change the bit rate. Is this normal? Why would it be so different?

Sounds about right. When you optimize like that, DVDA has to decompress the MPEG and then recompress it, at which point it will go ahead and prepare the project - the decomp/recomp is time consuming and you lose some additional quality - you'd have been much better rending directly from Vegas at an appropriate bit rate to accomodate the length of material.

And.. sory to mention this after the fact,.. but unless you have a crazy amount of motion menus, that probaly would have fit w/o recompression.

I noticed that the line at the bottom that shows how much you have on your DVD turns red pretty early. You are good all the way to 4.7GB, but DVDA warns you well before that. A bit premature in my oppinion.

2.5 hours would not have fit at the default bit rate that vegas renders at.
