Rendering before import

Just a question about rendering. Since DVD-A uses the same Main Concepts engine as Vegas 4, wouldn't it be better to render from Vegas as AVI-DV and then let DVD-A render the final MPEG to the best quality that will fit on the DVD? My thinking is that if I make the MPEG too small or too large, and DVD-A re-renders it, MPEG is a LOSSY compression and more quality will be lost. True, the DV file takes a bit more room, but if we have the room, would this not be a better workflow for quality's sake?

bump...

So what is the "official" response. Is it better to render to avi/dv and let DVD/A do the mpeg2 compression, or render to mpeg 2 from Vegas4 first. I really want to know.

Thanks,

Personally, I render to MPEG2 from Vegas. You have more control over the rendering process there. When you import this file into DVD-A, it will NOT re-render the file so you will not get a quality hit by doing it this way.

I render all content that doesn't need to get touched by DVDA in Vegas. For menu backgrounds, etc. It makes sense to render those out as a better format DV or HuffYUV AVI and let DVDA render to MPEG2 with the buttons, text, etc. Rendering to MPEG2 first in these cases would leave you with lesser quality (possibly hard to tell, but why add it in).

You should avoid re-rendering your MPEG. So, you can render AVI/DV from Vegas and let DVD Architect render to MPEG, where you can batch the rendering and set bitrates, or you can render MPEG from Vegas and just bring it into DVD Architect with no re-rendering (except for the 16:9 bug that will be fixed in an update). This could be useful for elements you are going to user many times.
