I use Sony Vegas 6.d and render my videos in Mpeg2; I use the default template. When brought into DVD Architect it must be rendered again. Is there a template that will eliminate, or reduce the render time in the prepare mode before burning?
You want to render (encode) your video using one of the DVD Architect Video Stream templates. There are different ones to choose from depending on whether your content is PAL or NTSC, and widescreen or regular aspect ratio (the regular's just don't mention widescreen).
DVD Architect likes the audio to be in a separate file, so the above templates do not include audio. You should render (encode) your audio to a WAV or Dolby Digital AC3 file. Save it to the same directory as your video file and with the same name (but the proper extension), and DVDA will pick it up automatically when you add the video file.
