Timeline/Clip settings for 24p

for best 24p to DVD footage you record 24pa, capture in vegas, then open a new project...
Now in this project you set it to:
Template - NTSC DV 24p (23.976)
Frame Rate - 23.976 (IVTC Film)
Field Order - None (Progressive)
Deinterlace method - None

Correct? Then if your rendering to do more editing its 2:3:3:2. 2:3 if your sending to DVD.
(just making sure its not the fault of my problem)
Well heres my problem, Ive fixed it but Im looking for an explanation as to why it did this:
Im in a project with above settings and i have two clips. When i render, regardless of 2:3 or 2:3:3:2 it doesnt actually render the proper frames after I play back the rendered clip. In the timeline the first clip is above the other and its got a mask removing part of it (the edge of a tree) and the tree is a transition element moving across the screen and revealing the next shot as it leaves the screen (moving right to left). The mask has no feather so it is very sharp and when i render I can see parts coming through the mask because the frame isnt matching up with what I was seeing in the playback from the timeline.

I fixed the problem by right clicking the first clip and choosing "Disable resample". What exactly did this do? Should I turn off "sampling" for all my clips?
 
When you say you are rendering "2:3 or 2:3:3:2", it is not clear to me whether you are adding the pulldown when rendering, or, adding the flags for your dvd player so that it adds the pulldown to the 24p video on the dvd (in this case it would say "23.976 + 2:3 pulldown"). In the former case, you would be adding pulldown (and thereby converting to 29.97 fps), and that may be the source of your problem; in the latter case you are not actually adding the pulldown, just the flags so that your progressive dvd player knows to add the pulldown for a 60i output on the dvd player (if playing on a traditional NTSC TV). I think in this case "disable resample" may be causing Vegas not to generate any new frames from your 24p clip because it is trying to match a 29.97fps in the clip below it (due to the pulldown that you adding when rendering).
 
I was doing "selectively prerender clip" and choosing avi with 2:3:3:2 pulldown (its one of only 3 options, other two being dv 29.976 and 2:3 pulldown. Both clips are in 24p. Where do I choose just to insert flags vs other option. And are those settings correct for a 24p project? Thanks
 
Try prerendering in "default template (uncompressed)" instead of the "24p / adding pulldown." Try setting your resample back to the original dafault "smart resample" (although I don't think this will matter if you prerender in the default template of 24p). I think this will give you correct sync with the top and bottom clips. Then, when you go to render the project, go to File, render as, and select the 24p dvd architect NTSC video stream (which keeps as 24p on the dvd, but adds flags in pulldown is required by your viewing medium). This of course assumes you want to output your video on dvd as native 24p but have the ability to add pulldown by the dvd player for NTSC playback.
 
With uncompressed, I still got the inbetween frames added in making the mask not line up. The only way I've been able to fix it is with resample turned off. So render to avi inserts pulldown and mpeg just inserts flags? Is it ok to render avi with pulldown and bring it back in for editing later? Flags seems to be the only way to accomplish true 24p video.
 
The description for "uncompressed" selective render is that you get 23.976 fps, so I am surprised that you still see the misalignment when you selectively render this way. I suspect that it is rendering 24p, but that different frames are being rendered into the 24p video from what you want. I not sure how this is happening. Are you sure your project properties are set to 24p timeline, progressive, frame rate 23.976? Also, are you sure you are removing the pulldown when you bring the "24p" video into your project (by checking the box "allow pulldown removal when opening 24p dv"?
 
Yepp pulldown option is checked and project properties are correct. I too am confused. Even when I prerender a single clip in uncompressed, the motion seems to get blended with other frames. Then when I turn resample off its smooth and progressive-like. Yet I have field order set to progressive, and deinterlace method is none as well but it still doesn't come out right
