Rendering MPEG from Sony Vegas
Hi all,
I have about 5 hours of SD footage shot with a Sony HDR Sr-11 to render and fit onto a dual layer 8.5gb DVD.
When i render to DVD-Architect using the mepg2 widescreen template, it ends up about 9.5gb, too big for the disc.
Sony Vegas Movie Studio 9 does not allow me to make my own custom mpeg 2 render so i need to render in mpeg 1, and I was hoping someone could tell me the best mpeg 1 render settings to use, that will give me roughly a 20% decrease in final file size, while still obviously giving me the best quality possible in widescreen. Ive tried the default mpeg 1 template, but its is poor compared to default mpeg 2.
Id appreciate any help.

Try using ‘Mark’s DVD Bitrate calculator’ available here…

Thanks for the reply Jeff.
That calculator is recommending a bit-rate of 4080 (i assume that is kbps ?) which it says is within the range of a good quality SD dvd.
So how do I tell sony vegas to use that bit rate?
In the settings for mepg 1, i can specify a constant bit rate, (currently at 1,200,000 bps) or I can allow it a variable bit-rate and specify a maximum, minimum and average.
What do you suggest i do?
Should I specify a constant bit rate of 4,080,000 bps as per the calculator? Does a higher bit rate not increase the size of the rendered video?

I don’t have much time now. But go into the preset for MPEG-2 ‘DVD Architect video stream’ and set the VBR bitrate and save as your own template.
If you need more explanation I will be back tonight.

”But go into the preset for MPEG-2 ‘DVD Architect video stream’ and set the VBR bitrate and save as your own template.”
Unfortunately Sony Vegas Movie Studio does not allow me to customize the mpeg-2 dvd architect video stream.
Thats why my original question was how can I render in mepg 1 to the best possible quality?

DVD only supports MPEG-1 at 352×240… yes, this is terrible compared to MPEG-2 at 720×480 (assuming NTSC numbers). No matter what bitrate you specify, it’d going to look bad on DVD.
You really need to adjust the bitrate you’re using to render MPEG-2. Can you render your final project to some intermediate, high quality output format, and let DVD Architect encode it? This isn’t the best way to work in the Vegas Pro workflow, since I can adjust the bitrate for MPEG-2. But I can load in any number of non-MPEG file types in DVD Architect, then use the “Fit to Disc” function to get the proper MPEG-2 (CBR-only) bitrate.
If you can’t do this, the simple answer is, get better tools — you can’t get the result you want with the software you’re using.

I’m sorry I didn’t know Studio had that limitation.
Can another person familiar with Studio help out here?
