Rendering slideshow to DVD: any point in 30p?

[bigass]

Hallo, all.

I got some great help here when I was asking about rendering a slideshow project for my recent wedding: https://forum.videohelp.com/topic373786.html ..

Now I'm looking to put it (and assorted other stuff) on a DVD for family.

Here's my line of thinking: I want the slideshow to look its best on all systems -- clear on regular TVs, clearer if possible on PCs or other progressive displays. So, I'm inclined to render it to 30p MPEG2, imagining that there'll be less flicker on progressive displays if I do that.

Am I misleading myself?

Ought I just render it to plain old-fashioned 30i? ... and maybe throw in a high-res progressive xvid on the DVD for computer uses?

Here's a link to the video in question ... and this one's a 24p render I made for the actual wedding presentation ... I liked the film-ish look on the big screen, but it's not as charming on the teevee: http://vimeo.com/7072228

Many thanks.

Bump? I'm not out to start/finish an argument like in this current thread: https://forum.videohelp.com/topic374448.html ... but I wonder if I'm asking a similar question?

If my source is mostly JPGs and misc effects generated in the box, would I find any gain encoding my DVD-destined output at 30p?

If there is room on the DVD, do what I usually do and include an "EXTRAS" folder on the DVD that contains any other files like a divx/xvid/wmv version of your slideshow.
Imgburn, for example, will let you add this "EXTRAS" folder after you specify the authored VIDEO_TS folder.

Not finding much advice here, but some deeper searching through Google has yielded this piece of advice from Douglas Spotted Eagle, who is reputed to genuinely know what he's talking about:

Rendering to 30p SD is just fine, particularly from 30p source, and from HD source.
If the display is 30p capable, it'll show 30p. If not, it displays as interlaced.
Either way, it's more flexible and higher end quality than hoping for a good deinterlacer and rendering interlaced media

Alright, so the options I'm considering are:
- render to 'standard' DVD mpg2 -- which, I guess, is 30i
- render to 24p
- render to 30p, under the possibly delusional notion that there's something 'better' in there

Again, thoughts?

Some quick thoughts:

"NTSC" DVD by standard is either 29.97 interlaced or 23.976 progressive. There is no "30P".

You can fake 29.97p by interlacing two fields from progressive source (i.e. both fields from same time sample vs. normal 59.94 field sample rate). The end result should look the same for stills but transitions or motion effects may be problematic since the DVD player and HDTV are expecting a 59.94 field rate.

My advice would be to render transitions and effects at progressive 23.976 fps rate and encode/author the DVD with progressive flags.

I would add an HD 24p (or 60p if space available) render as a separate file on the DVD for computer or media player use.

Excellent input, sir. Thank you for that.

So, it looks like I'll give a shot at having Vegas render a flagged 24p mpeg2 for use on the DVD ... and I'll render out a separate high-framerate, high-res version as a bonus for computer users.
