HMC150 HD to vegas to DVD . . .

I've been shooting sports with an HMC150. On the first shoot I used 720 30p. On the second I used 720 60p. However, my final delivery method is dvd. Should I even be bothering with 60p? When I export to mpeg2 my only option is 30fps and then DVD architect goes to 60i. My other question; It always switches over to lower field first. Should I output in progressive scan, or just leave it interlaced. The original footage is obviously progressive, but is this benefit going to be lost through the SD conversion process, and then the move to DVD?

Thanks.
 
I'm in the middle of a 60p sports project. I tested out a flow that should work, but I intend to use cineform NeoScene to help. My plan? Render to Cineform at 720p60. Then make a .mp4 final render for PC viewing using MeGUI and H264 codec at 60p. For the DVD, I'll send the 720p60 mp4 back through Cineform and convert to 24p AVI. AVI goes back into Vegas and out as .mpg for DVD at 24p. The key is that NeoScene does a nice job going 60p to 24p. Yeah, all that rendering reduces quality, but only in the steps going from 720p to 480p, so it won't matter much.

My understanding is that even though you have to select a 60i template when starting a new project in DVD architect, the actual dvd will be progressive if the media is progressive? But then I'm reading that the only way to make a progressive scan dvd is for it to be in 24p?

If the only way to get a progressive dvd is 24p, is there a benefit to shooting 60 over 30? Aren't you losing most of your frames anyway? Someone told me that less blurring will occur if I shoot at 60 and convert it later. It sounds logical, but it seems like the end result would be choppier (especially going to 24).

My assumption is that the average person watching this is going to have a $50 dvd player hooked up to their 42" vizio with composite cables, so really it seems like the effort to keep it progressive might be pointless. My concern would be that the benefit of progressive scan would be lost to most people, and that smoother footage would be worth the tradeoff.
 
For sports you usually want to shoot 60p and make a 60i DVD

Unless there is very limited motion in your sports (i dunno, maybe a chess match :) ) , 24p is going to look very choppy, no matter how the conversion is done

DVD-video doesn't support 60p, but 60i is the only way you keep the temporal resolution and smoothness

For blu-ray it's no brainer 720p60.

Ok when exporting from vegas to "DVD Architect NTSC Widescreen video stream" the highest framerate option is 30fps. Unless I change the "level" to high or high 1440, then it lets me export at 60. However, once I get that file into DVD architect it wants to recompress. Also, when I check the project properties in dvd architect, 29.97 is the only option for framerate. What's the secret here?
