Guys,
It is definitely an ac3 template problem and there is more to it than using the studio version or just setting dialog normalization to -31 (although it is important that it be set to this value).
Go to the Preprocessing tab under customize template. Then make sure Digital DE-emphasis is unchecked, line mode profile and RF mode are set to none. Also make sure RF over-modulation protection remains not checked.
Under the Bit-stream Tab also make sure that Include audio production information is not checked.
These changes to the template were discovered with hard learned lessons and a lengthy process of trying to figure out how to get adequate volume “out” of Vegas and “into” DVD Architect.
It goes back to Vegas version 5 and DVD Architect version 2.
It still holds true today.
These settings included in the pro version of the ac3 encoder included in Vegas are indeed for various types of Dolby Surround.
The ac3 encoder can do an excellent job at Dolby Surround but it takes tons of research and experimentation to “get it right”
I’ve used the template with the modifications I’ve outlined above and had very good results. Give them a try, I think you will get good results as well …
