System information
The  Sony Creative Software Inc. AC-3 and MainConcept MPEG-2 encoders provide  templates that will 
produce files that do not require recompression (unless  the file size is too large to fit on a DVD).
AC-3 audio (.ac3)
Sample  Rate Bit  Rate Channels
48,000 Hz 192 Kbps
(64 Kbps to 640 Kbps is supported)
Stereo
48,000 Hz 448 Kbps
(64 Kbps to 640 Kbps is supported)
5.1 surround
PCM audio (.wav or  .w64)
Sample  Rate Bit  Depth Channels Compression
48,000 Hz 16, 20, or  24 bit  Stereo Uncompressed
96,000 Hz 16, 20, or  24 bit Stereo Uncompressed
NTSC MPEG video (.m2p,  .mp2, .mpg, .mpeg, .mpv)
If you’re using the MainConcept MPEG-2 encoder in Vegas Pro software, use the DVD  Architect NTSC 
video stream or DVD  Architect 24p NTSC video stream template to render your video stream.  You'll need 
to render your audio stream separately according to the parameters  listed in the AC-3 audio or PCM audio 
headings in this section. 
If you're rendering with a  different application, the following settings will produce a compliant  NTSC 
MPEG-2 video stream.
