Why does DVDA re-render?

I can't make any sense of the DVDA manual - it tells you how to add all the bells and whsitles, but not how to do the basics like make a DVD!

I decided to do a test onto a DVD+RW using a 2 minute clip. I used the correct template in VV4 to make .mpg and .ac3 files from the .avi original, it took about 4 minutes to render.

So why does DVDA re-render the video?

When you prepare to make the DVD under "Optimise" tab clear the Recompress video check box. When I use separate video and audio streams I only encode the audio to AC3 as I have rendered the video to Mpeg-2 separately. Have had no problems at all.

I think I'm about to answer my own question, and prove the point about the manual not telling you the basics! It seems you have to select the correct standard and aspect when starting a project as DVDA is too dumb to use the properties of the clips you insert.

No wonder my first test was jerky, it was putting 625 stuff into an 525 DVD ;-)

On the topic of rendering, is there any difference in quality between rendering .mpg in VV4 compared with inserting the .avi into DVDA?

They both use the MainConcept encoder but I think it is quicker to encode in Vegas first. MainConcept is trialling a beta version of their updated encoder and it is quick with 2 pass encoding, maybe a while before it filters down into Vegas and DVDA. By then DVDA will be a much more versatile program and with a quick encoder, here's hoping!
