Progressive scan help?

I have a question about using a progressive scan dvd player.

If I shoot 24p ntsc and output with Compressor using mpeg-2 ntsc then with using a progressive scan dvd player is it essentially removing the pull-down from the footage?

Also, in Compressor when you compress to mpeg-4 I noticed there is a progressive scan option, is this the same question as above?

One more thing, when making an mpeg-2 when would you use the 24p option in the "encoder" section as opposed to the NTSC option?

Maybe this is clearer? I apologize.

I was wondering, if I shoot 24p do I use the 24p option when encoding to mpeg-2 in Compressor or leave it at NTSC? I have been leaving it on Automatic. also, is field order an issue? That's been on Automatic as well.

Another quick one, in terms of progressive scan, if one were to get a progressive scan dvd player and monitor does that mean both would convert the 24p footage on the fly to progressive?

Recap: Is there any difference then if I go, from 24p in an NTSC timeline in FCP, to Compressor using the same settings to then a progressive scan setup for viewing? Not sure if I should be doing anything in Compressor differently from using the Automatic settings.

I don't shoot 24p Advanced since I do not go to film etc.

If you make a 24p MPEG (with NO pulldown), and encode a 24p DVD (no pulldown), then the progressive-scan player will either display only the 24p frames on a progressive TV . . .

Or, if it's being displayed on a standard TV, the DVD player will add the necessary 2:3 pulldown.

The decision between shooting advanced vs. standard has nothing to do with going out to film; if you're editing in 24p, then always shoot advanced, especially if you're using FCP. Trying to get native 24p from standard pulldown in FCP is a pain, and if you want to make 24p DVDs, you need to do it.
 
I use FCP 3.0.4 so I'm not sure about editing 24p in the timeline.

Also, are you saying with Compressor I would select the 24p as opposed to NTSC? I usually leave it on Automatic.

Thanks
 
also, it seems you'd always edit 24p Advanced if the DVD player adds the pull-down? or are you saying only progressive scan players do this where standard dvd players don't?

I have Barry's book and he reiterates what others have about 24p vs. 24p Advanced, the former having to do with going out to NTSC video.

again, thanks for the help.
 
Well, if you're using FCP 3, then you can't edit in 24p. In that case, shoot 24p standard, not advanced.

I don't know enough about Compressor to know if it will convert 60i to 24p. It might; don't know.

But if it does, you wouldn't want to do it with 24p footage. I don't think the results would be very good. The only way to properly convert it to pure 24p would be to remove the pulldown, and that's not what Compressor would do.

I'd post in the FCP forum to be sure (and make sure you tell them exactly which versions of the software you're using), but I don't think you can make a 24p DVD with your current software.

As for the DVD players, every DVD player ever made will add pulldown for displaying a 24p DVD on a standard TV. Hollywood movie DVDs are 24p.

A progressive-scan player, though, can display the native 24p frames without adding pulldown on a progressive display; a non-progressive scan player can't.
 
Yes, got all that and thanks for the help.

I did notice in FCP 3.0.4 with the timeline preferences you can select 23.98. I don't think this would work since it seems later versions advertise the ability for 24p - why would this version do the same?

I also wonder if you can put 24p and 60i videos on the same progressive scan DVD?

I just can't decide if I should shoot 24p Advanced, do you gain any resolution or difference in how the images look?

I am running DVDSP 2 and this may also be unable to build the progressive DVD, right?
