24p questions

Hugh DiMauro · January 3rd, 2007, 01:06 PM

Hi Chris:

From what I can remember, the DVX shoots 24p to tape using one of two pulldowns, 24p (2:3) and 24pa (2:3:3:2). It's not true 24p on tape, it is actually interlaced on tape. It converts to 24p on your editing software. So I think if you set your Adobe PPro 1.0 capture settings to 24p you should be okay.

Now, for the REAL answer, fire off an e-mail to our resident expert Barry Green.

Good luck!

Chris, if you shoot in 24P Advanced mode, your editing software has to be able to remove the pulldown (the extra interlaced frames) to be able to give you 24 discreet frames per second. Not sure if Premere Pro 1 can do that (I believe 1.5 can). After Effects can interpret and convert 24PA footage to straight 24P.

But you should determine first whether you shot in regular 24P or 24PA. They will both have interlacing, but 24P Advanced will sort of stutter a bit on playback from tape. That is normal. Whereas regular 24P will playback smooth (and suited for a regular 29.97 timeline).

I will shoot a short with a dvx100, and I wonder is it better to shoot 24p instead of normal mode (interlaced) on all circumstances?

thank you

Of course not; there's a reason both modes are included.

24P is great for giving the filmlike "drama" look; 60i is appropriate for the "live" or "reality" look. Network dramas are shot on film or 24p video; news and reality shows are shot 60i for that "immediate" look. Sports is shot in 60i or 60p. Events that need to look "live" would be better off with the 60i setting.

Thank you for your answer Barry,

I'll ask one more thing, I also have a chance to shoot the movie with an fx-1. Should I shoot it 720p or 1080i? It's a drama, so progressive scan is what I'm looking for, but is hd resolution with interlaced scan(1080i) better?

And it's all meaningless to shoot it hd, if you'll watch the movie on a pal or ntsc system, right?

If you shoot with an FX1 you won't get 720p at all, it doesn't offer 720p.

I'd choose a DVX in 24P over an FX1 in 1080i. I'd take an HVX200 or a Canon XHA1 over either one of them though.

24P is what matters for the feeling of it having been shot on film. Hollywood has had access to interlaced high-def cameras for a long time, but never bothered to use them until they got the CineAlta F900, which combined high-def with 24p. FX1's a decent enough camera but moviemaking isn't what it was designed for. XHA1 in 24F, HVX in 1080/24p, or even a DVX in 24p would all give you the filmlike look.

I'm sure others will disagree, but that's the way I'd go.
