How to render a video in sony vegas in order to became the size to fit in DVD9?

[Mike Kujbida]

Render the video using the DVD Architect NTSC (or PAL) video stream or DVD Architect NTSC (or PAL) Widescreen video stream MPEG-2 templates.
Render the audio using the default Dolby Digital AC-3 Pro template.
Give both files the same name (i.e. myvideo .mpg and myvideo.ac3) and render them to the same folder.
That way, when you load the video file into DVD Architect, the audio will automatically follow.

Depending on the length of the video, you may need to use a custom bitrate to make things fit.
Since you want to put this on a DVD9, you’ll need to determine a layer break point as well.

These issues have been discussed a lot on here so please do a forum search if you have any questions.
