DVDA re-rendering!

John McCully wrote on 5/31/2003, 11:47 AM

OK, so using my new Sony PDX10 I shoot 16:9, import into Vegas 4c using the NTSC DV widescreen properties, minimal editing, and render to the NTSC DV widescreen template. Then I import the rendered file into DVDA and burn a simple DVD. But DVDA re-renders the file with what appears to be degradation in quality.
So, my questions: why should DVDA re-render and why the quality reduction. Most grateful for comments.

Is it REALLY rerendering? Did you check under optimize to SEE if DVD-A is set to recompress the video stream? Actaully reading all those warning and information notes file by file. It will recompress the audio if, you use the regular MPEG-2 template. It shouldn't touch the video assuming it fits AND you used the MPEG-2 template, not the AVI one. It will also recompress if you project is too big to fit on the DVD.

You can also watch and see exactly what DVD-A is doing. Rather boring, but you can watch the various progress bars go by as DVD-A does its thing. Its a two phase process as far as processing prior to the actual burning phase. First what needs to be recompressed will be. Then the files are made. Then once that's all done you're ready to burn.

Thanks BillyBoy, my mistake was to render in Vegas as an avi. So now I used the MPEG-2 template, widescreen, and all is well; no recompression in DVDA. Again, many thanks.

I tested a Procoder Rendered AC3 & it wanted to re-render, why? DVD Workshop has an option for it not to re-render a DVD compliant file.
