What format should I export my project in so DVDA doesn't compress my movie's audio? Right now I am using the MPEG2 - DVD NTSC template from Vegas, everything works find but DVDA says ".. audio of BLAH will be compressed .." -- should I be using a different format?
DVDA tries to compress audio to AC3. This is a good thing as it takes up less disc space. Actually, if you let Vegas do your encoding using the DVDA template, you can build your video stream and audio stream (seperately). Be sure to name them exactly the same. The suffixes will be different of course.
Over in DVDA, when you put your encoded video file on the menu, the audio transparently attaches to it. You're ready to burn at that point. Vegas encodes faster than DVDA too.
You have to export the audio separately. Either as ac3 or wav.
They should have the same name as the mpeg2 file with the appropriate extension. This way DVDA will find the audio file without being told so long as they are in the same directory.
