1080 to DVD...again

I have been here for a while and will serve me right if you tell me to search, but...it's been a couple of years since I've read anything new. So currently what is the best way to make a DVD from a 1080/30p source without inducing a lot of moiré and artifacting. Is it possible to do within Vegas-Architect? It seems to me that a lot has been added to Vegas since the last time this was discussed.

Here is what I've been doing since I learned of this workflow (courtesy of vxtrocketeer and others). This worked well for me with AVCHD and 24p (23.976p).

I use Avisynth to skip the creation of a *.avi file. Nick Hope and others have lead the charge of the best ways to use Avisynth.

You are shooting 30p. Not sure if this will produce good results for you but it's working considering.

[I]1. Shoot at 24p (23.976p, ok?). Edit at 1920x1080 24p. Render from Vegas to 1920x1080 24p avi master. (I use Cineform to keep the avi visually lossless but manageable in size. Lagarith works perfect, too.)

2. Render master avi from (1) in VirtualDub using resize filter, e.g., to 720 x 405, using Lanczos3 algorithm (important!). This gives a 720 x 405 24p avi (also Cineform, in my case).

3. Render 720 x 405 24p avi master in Vegas to DVD-compliant MPEG-2. (I assume you don't need details here.)[/I]

Here is the thread where I lifted the above quote:

I posted on another thread that I used to use a workflow where I used debugmode frameserver, an avisynth script for the resize, and hanks encoder (hcenc), and I got really great results. The area where this workflow suffers is speed.

I have since decided that you can get good enough results from the Main Concept Mpeg 2 Dvd Architect templates, as long as you customize them to bump up the bitrates a bit, and make sure you set the render quality to "Best". It's not enough to set it to "Best" in the preview window, you have to set it in the project properties or the render template. This renders very fast on my machine.

Now, I don't do much 30p for DVD. 30p will get interlaced, because dvd's are either 24p or 60i. I would assume that it would be best to resize first then interlace, and I'm not sure what vegas does, so maybe an avisynth script will be better for that control, but If you are satisfied with the vegas rendering it might not be worth messing with.

That's my 2 cents.

If you have a reasonably short piece of native 1080i, I would like to try an experimental method I have been working on this week. A clip that shows both motion and detail maybe?
I'm getting quite good results with my own clips, and want to see if you like the results with yours. My method will produce a progressive DVD.

If you'll upload some native 1080i footage to Dropbox, MediaFire, or Google Drive, I'll return a SD .mpg file suitable for DVD Architect. If you really like it I'll tell you exactly how I did it. If not, I'll keep experimenting . . .

Interested in "how you did it"

All in good time. I've only spent a few hours on it, and want to make sure I've got it right . . .
