Do you render with 32 bit and 2 pass? Why or why not?
History: I was concerned about low bit rates with Vegas Movie Studio Platinum so I downloaded the Vegas Pro trial. Comparing the Studio and the Pro I think the bit rate increase did make a more detailed, less fuzzy product. It wasn’t so dramatic that you sit and say wow but it was definite improvement.
So now I have two more rendering questions using Vegas Pro:
First, 8 bit vs 32 bit floating point. The docs briefly mention this, it does increase rendering times by quite a bit, I was hard pressed to notice a real difference. But I have a 15 year old 20″ CRT. So do you render with 32 bit? Would it make a difference on a larger tv?
Second, 2 pass rendering. The docs say absolutely nothing about this. What does it do, average the two passes, throw out the worst from the two passes? Do you render with 2 pass?
Thanks for the help, I’m very close to finishing this project. 24 miniDV tapes, 17 DVDs, titles, music, editing. It’s been something considering I had never done any video editing before. And I couldn’t have finished it without the help from this forum. And I should add, I’m more than happy with my choice of Vegas. I’ve found it intuitive for the most part and stable (except for numerous crashes when accessing help files). I’m especially impressed with DVD Architect. With no prior experience I was able to make some complex menus after some reading and a little experimenting.

2-pass doubles your render time in order to make better use of available bits. On the first pass it calculates the bits needed for each frame and formulates a plan to make best use of them. On the 2nd pass it does the actual encoding following the plan it has made.
