I never understood the Disc Properties (in Project Properties) of DVDa.
I read the readme and well, I still don't get it.
You have Bit Rate, Aspect Ratio, Frame Rate, Resolution...what bearings does this have if I already rendered this out of vegas already?? Does it override what I already rendered out of vegas?
*IF* you choose for DVDA to re-encode your stuff, yes, it uses those as a base. You can always override that in the prepare properties too. :)
Also effects menu's, buttons, etc. Everything non-actual movie.
It can be independent of the actual movie you're showing though: the menu can be 16:9 & the playback video can be 4:3, for example. If you're doing menu backgrounds in Vegas (or another program) you'd want your Vegas render settings to match the project settings.
