Trying to get 1:50 on a DVD with Vegas

[Mike Kujbida]

The maximum (audio & video) file size for a single layer DVD can’t exceed 4.3 gigs so yes, you do need to adjust the bitrate when rendering from Vegas.
My bitrate calculator gives the following settings. This assumes AC-3 audio.

CBR: 5,000,000
VBR: 8,000,000 / 5,000,000 / 3,000,000
(Max. / Avg. / Min.)

Here’s a link to an online calculator on the VideoHelp site.

Here’s a link to Edward’s newsletter detailing the DVD authoring process.

Here’s a link to the bitrate calculator I use.
Note that this links to a zipped file.

Check my responses in the Correct Bitrate settings in Vegas for DVD Architect thread for the settings I recommend and why I do so.

Mike,

Thanks for the advice. One question. In your exp, how low can you go on bitrate before you start loosing video quality?

Rick, I personally don’t go below 4,000,000 either as a CBR value or as Average for VBR.
Depending on the quality your source material, this may need to be even higher.
My usual recommendation is to burn a short segment (just a few minutes) at the intended setting to an RW and see what it looks like on a TV.
That method, better than anything else, will tell you right away if it’s too low.
