Am I the only one who's baffled by this? I found the program's documentation to be somewhat pathetic in this area...
Are the project properties to be set to the actual characteristics of the source footage? (what if using mixed sources?) OR are the properties to be set to what you'll most likely render out to later?
I've had good results with Vegas, but an awful lot of trial-and-error has been going on. -I make 10s test-renderings with various parameters changed and finally crunch out a final version with the settings I liked best (READ- I don't know what I'm doing... -er, well, I have a clue but still feel like I don't know enough...)
Cheers
