Regarding Vegas Movie Studio 16 Platinum, do I still need to render the video and audio separately as with previous versions or is it done all in one? If so, how do I render the audio for DVD Architect 7? For example, what is the codec and settings I need to choose for rendering audio?
There are two options for audio for DVDs, either WAV or AC3. WAVs tend to be bigger files so if space on your DVD or Bluray is a concern, or if you are making a 5.1mix, you will want to use AC3. And yes, it is always better to render separately. Audio for video is always 48k. Bitrates can vary.
DVD Architect requires separate video and audio files to make a DVD. The easiest way to do this is to select "Make Movie" in VMS, select "Burn it to DVD" and then select "DVD with menus". That will create the separate files and open them in DVD Architect.
If you want to render the files yourself, choose MainConcept MPEG-2 for video and then render again using Dolby Digital AC-3 Studio for audio.
