Interlacing and Deinterlacing in Vegas

[Andrew Bosch]

Hi,
I have a Canon XH-A1. I typically shoot video in HDV 1080/60i. Now, I want to make a DVD. This will be for an audience in North America, for playback on your regular-everyday DVD player on HDTV's.

A few questions about the Project Settings and the Render Settings in Vegas when wanting to create a DVD.

First, in 'Project Properties', there is a drop-down menu called "Deinterlace Method" under which there are 3 options:

1.) None
2.) Blend Fields
3.) Interpolate Fields

Now, when I render, I typically choose the DVD Architect NTSC Widescreen Video Stream Template. But, in the custom settings, under the Video tab, there is a drop down menu called "Field Order" with 3 options.

1.) Upper Field First
2.) Lower Field First
3.) None (Progressive scan)

My question is this: Shouldn't the Field Order options be in the Project Properties and the Deinterlace Method options be in the Render Settings? This seems counter-intuitive to me...

If my project were shot Upper field first or lower field first or shot in a Progressive mode, I could then choose those options in my Project Settings. Visa Versa, I can't choose if I want to Deinterlace and how I want to deinterlace when I render??? This doesn't make sense to me!

Could somebody please explain what these respective settings mean and how they relate (if they do) to making a DVD?

What settings should I choose respectively if my source footage is shot in 1080/60i?

I don't want any interlace artifacting and want to preserve as much of the quality and resolution of the source footage that I possibly can for DVD.

Does anyone have any input?

Thanks

shoot interlaced, 60i and edit progressive, vegas is ok deinterlacing, I use interpolate, and deinterlace with cineform, when capturing, edit 29.97 progressive, render progressive, when rendering mpegs 2 for dvd, keep bit rate at 8 or below, cause the dvd may not play correctly
on tv if higher
