2332 Pulldown mpeg 2 Template

Hi

I want to render out to DVD Architect using the 24p template but from what I can tell it only offers 2-3 Pulldown. If I want to render out using 2332 Pulldown I have to render as an avi file. If I do that will DVD Architect compress the file to mpeg 2 with 2332 intact? How does everyone else here do the 24Pa out to DVD?
 
if you import a compressed 2332 avi file to DVD architect it actually looks pretty good. but i still prefer using the Mpeg 2 format when rendering. its good to render both, one to wacth on your computer and one to show on TV, but put them both on the same disc and then compare
 
It doesn't work quite like what you're thinking. When you're rendering out for a 24p DVD using the DVD Architect template, you're rendering a pure 24p file which has flags for 2:3 pulldown; it doesn't add frames. It's burned to disc as a 24p file, and then the DVD player adds 2:3 pulldown for display on an NTSC set. It does not add pulldown if you're watching on a native progressive set.

Unless, of course, you're making a 29.97 DVD, in which case, DVD Architect will re-render the file into a 29.97 file. But there's no reason on Earth for you to do that.

But if for some reason you wanted to render a file as 29.97 to make a 29.97 DVD, you wouldn't want to use 2:3:3:2 pulldown, anyway, for several reasons. (And I'm not sure MPEG-2 even supports it, for that matter.) Advanced pulldown is NOT meant to be used for final output, because while the frames are arranged very efficiently for pulldown removal and editing, they are not arranged ideally for viewing. Every second and third frame of every four-frame group that's split up in 2:3:3:2 pulldown is onscreen for 50% longer than the other two frames, causing more motion stutter than should actually be there. Advanced pulldown is for editing, not for watching.

In any case, if a 24p DVD is what you want, just use the DVDA templates. They're already set up for optimal performance.

You can do that if you're burning the files as data to be watched on a computer (through Media Player or whatever), but you can't do that to watch on a set-top DVD player. They will play only MPEG-2, so if you're burning a video DVD, anything that's not compliant with DVD Architect's standard will be re-rendered into a compliant MPEG-2 file. So, you may have both files on the DVD, but if you're watching them through a DVD player on a TV, you're watching two MPEG-2 files.

I'm interested in the quality of the final 24p DVD and from what I have read and from what you have said, DVD players use 2-3 pulldown so I will be using the Vegas - DVD Architect 24p template for MPEG-2. However when you say it is more efficient to use 2-3-3-2 pulldown for removal and editing how does it differ? Not technically but what I mean to say is will I actually notice an improvement in editing my project in some way? Is it better because the final quality of the video will be slightly improved? And if this is the case, shouldn't I shoot in 24pa over 24p all the time?
 
Advanced pulldown is designed to make the process of pulldown removal easier. It also takes advantage of frame-based compression, whereas standard pulldown uses field-based compression. So yeah, there will be a slight quality advantage. Whether or not it's noticeable is another question. But like I said, you don't want to WATCH footage with 2:3:3:2 pulldown; you'd probably think it's stuttery.

If you're going to edit in 24p, which I assume you are if you use Vegas, there's no reason not to use 24pA, ever. You could use 24p if you're planning to watch the footage from the tape, or if you're going to edit in an NLE which doesn't edit in 24p, or if you're going to hand off the footage to someone else and you're not sure of their NLE.
