Do I need to split my project before burning?

Hi Mike,

Thanks for the information.

Gilles, the “Best” I refer to is a render setting option and it’s location depends on whether you’re using Pro 8 or Pro 9.
Either way, click the “Custom” button next to the “Template” box.
In Pro 8, it’s in the first tab that comes up (Video rendering quality).
In Pro 9, the Project tab has been moved to the very last position but it’s still in the Video rendering quality box.
BTW, if I’m rendering an MPEG-2 stream, I have the “Video quality” slider (found in the Video tab) set to maximum (31).
Remember that all your custom settings can be saved as presets for use the next time.

Hi Mike,

( I always use the bitrate calculator I’ve mentioned here several times and render MPEG-2 and AC-3 streams out of Vegas and then give these to DVDA for authoring. For your project, use a CBR setting of 8,000,000 for the 1 hr. DVD and a VBR setting of 7,904,000 / 6,320,000 / 3,972,000 for the 1.5 hr. DVD.)

Mike, I was always under the assumption that when you render out a project as Mpeg2, your compressing everthing. Then when you bring your compressed Mpeg2 into DVDA, it’s rendered again and recompressed once more losing the picture quality.

In Vegas Pro8 I’ve been rendering out as an AVI for video and PCM for audio which is uncompressed and then bringing it into DVDA to get compressed as a Mpeg2 and AC3. Am I in left field on this or what? Pleae let me know.

Ralph, there’s nothing wrong with doing it the way you are but I prefer to do the encoding myself rather than letting DVDA make the decisions for me.
Each to his (or her) own 🙂

Mike,

Thanks for responding and I’ll search for the bit rate calculator to put on my desktop.

Ralph 🙂

No need to go looking for it Ralph.

No. If you encode the MPEG and AC3 files correctly in Vegas Pro, then DVDA will not require re-encoding. (MPEG is encoded, not rendered, notwithstanding that Sony put the encoding processes in the “render as” menu).

If DVDA insists on re-encoding the project, then you need to go back to DVDA and adjust your encoding parameters. Most likely to reduce your maximum bit-rate.
