[doyal gudgel] "Do you mean we are capturing files off the disk in dv avi format?"
No. I'm talking about capturing the VHS tape. You plug the VHS player into the Canopus ADVC-55 and Vegas sees the ADVC-55 as a DV camcorder and captures the VHS tape to DV AVI which is 5x better quality than DVD MPEG2. Then you edit your video in Vegas and when you're ready to make a DVD to render the final output to DVD MPEG2.
[doyal gudgel] "To maker a playable dvd we still have to burn as a mpg So how much better is that ? "
Because you are editing the higher quality DV footage instead of the lower quality MPEG2 footage. If you edit lower quality MPEG2 when you render it again to DVD MPEG2 you loose even more quality.
[doyal gudgel] "where and how is the improvement? When I import the dvd it is imported as mpg. Right?"
No. I'm not talking about importing the DVD. I'm talking about importing the original VHS tapes directly to DV AVI.
[doyal gudgel] "Where in the process do I make a better project with a dv avi file? They all wind up as a mpg file on a dvd."
Right at the start. You capture your VHS tape to higher quality DV. You edit and color correct higher quality DV. Then you make the lower quality DVD MPEG2. Going from high quality to lower quality is better then starting with lower quality and re-generating more lower quality.
[doyal gudgel] " They all wind up as a mpg file on a dvd."
Yes, but one of them starts as higher quality DV which will yield a higher quality MPEG2 that's been edited.
[doyal gudgel] " Where in this "import, edit, render, burn dvd" can I improve? "
Import DV AVI. Edit DV AVI. Render DVD MPEG2.
[doyal gudgel] "Render to dv avi? It still has to get to the dvd as a mpg."
There is no DVD in my workflow (hopefully you see that now). It's a direct capture of the VHS tape to DV AVI via the Canopus ADVC-55 analog-to-digital converter. As I said in my previous post, this is compressed at only 5:1 instead of the DVD MPEG2 25:1 so more of the original information is retained while editing.
