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?
