Should I have the DVD player set to “progressive” or “normal”…
If the original video was in progressive format, then that’s what I’d use. Otherwise, leave it at normal.
…is the default settings for rendering to DVD the best choice…
If you mean choosing the “Default Template”, absolutely not. The bitrate is far too low for a decent wuality picture. Render the audio out as an AC3 file and choose the “DVD Architect NTSC video stream” template for your mpeg-2 file. As long as both file names are the same (MyMovie.ac3 & MyMovie.mpg), DVDA will import the audio as soon as you import the video.
Another thought, since this is being re-encoded, is that you might want to try a 2-pass encode for better picture quality. Render times will increase substantially though.
…it will be viewed on PCs and TVs?
You could render it out twice. The first render interlaced for TV viewing and the second render using progressive for computer display.
I tried this once and had a slight but noticable drop in quality…
This is to be expected. From a technical POV, you’re going from a 4:1:1 signal (miniDV) to a 4:2:0 signal (DVD). Now you’re capturing the DVD signal, converting it back to a 4:1:1 signal and then re-encoding it back to a 4:2:0 signal. It’s no wonder the quality drops 🙁
Adam Wilt’s site goes into it in much better detail, pictures included.
