Ok, for instance – the largest video I’m trying to render is 2 hours 50 minutes, so on the calculator I selected Disk Type DVD-5, Audio Encoding 224 Kb/s, entered a total video time of 3 hours 1 minute, and got a bitrate suggestion of 2200/2936/5872. I also have the Safety Margin set to 5% and the Kilobit Size is set to 1024. In Vegas my Output Format is MainConcept MPEG-2, DVD Architect NTSC video stream. I changed the bps settings to 2,200,000/2,936,000/5,872,000 and ticked the Include audio stream box (also tried it without the audio stream without any real difference in the result), hen I saved it as a new Template and hit Render. Everything else was default settings. I don’t know the exact file output size because I deleted the file, but it was at least 6 gigs.
Did I cover everything? 🙂
