Why do Vegas Pro and DVD Architect require audio and video to be used separately when encoding and making DVDs and Blu-ray discs?
DVDs and Blu-ray discs require different file types for both the audio and the video. For example, a DVD requires MPEG-2 video, but AC3 or PCM audio. The audio in an MPEG-2 file does not satisfy the audio requirement for creating a valid DVD. You dont need to break the audio and video out separately if you dont want to because DVD Architect knows you need to and thus will do it for you if you havent done it already. But Vegas Pro gives you the flexibility to do it yourself so that you have maximum control over the process.
