Benefits to shooting 24pn?

Okay cool. I think I get what's going on with the 24Pn thing.

I just have to test it out I guess. I still need to get slow mo, and it sounds like the best way to do it is in 24Pn VFR 60?

Why all over the place?

720/60 can mix with 720/24 only if you advance pulldown the 60 footage, but than you might as well shoot 24pn to start. 1080 can be downresed, but why bother. plus unless you have FCP 5.1 you wont have support for 1080.

You will have complete support for 1080/24p in Xpress Pro HD or Media Composer. P2 will input to DNxHD by usual methods in either system automatically (P2 or tape on MC, or just P2 on Xpress). Currently, however, you cannot digital cut DNxHD to tape from Xpress (DVCPROHD, no problem), but you can from MC, so you would use another system for that. But Avid DVD has just added Blu Ray output from any HD source, so that is a nice 1080/24P solution for either system.

However, I think 720P looks better anyway, and 720Pn is slick (except for the fact that it won't record to the new firestore drive).

Never slow anything down in post. That's an old, outdated, obsolete technique that we never have to put up with again. Just like "de-interlacing" -- it's over. Forget about it.

You can shoot VFR in 24pN mode, or in "over 60" mode. If you shoot vfr in "over 60" you can extract the active frames in post using the Apple Frame Rate Converter utility, which will remove the duplicate frames and give you a file that's identical in quality and motion performance to what the same clip would have been had you shot it in 24pN mode.

I have a question: Why is this the way to go?

If I had footage recorded at 24fps, and wanted 50% speed at one point in a clip, then wanted it to go back up to 100% speed... wouldn't it be wise to ramp? And in that case, wouldn't it be wise to shoot 60p? Or 720p/24pn VFR 60? That way I have 60 pure frames to work with?

I think I'm still missing something, here.
 
your correct. Shoot in slow motion, then if you need it normal speed, speed it up in post, that way the slow motion stay intacted and you can still do the effect you want.
 
If you shot 24fps, slowing it down to 50% is going to look awfully jittery, and will look nothing like as if you'd shot at 48fps in the first place.

If you know you're going to do that kind of effect, shoot 48fps. Playing every other frame back will give a good simulation of 24fps, and playing back every frame will give you the 2:1 slow motion you want.

Shooting everything at 60p will give you improper motion sampling for the 24fps or 48fps rates.
 
Okay, so 48fps is right and 60fps is wrong?

So you shoot 720p/24Pn VFR 48?

I'm so confused.

Here's a scenario: Guy throws a kick. On the launch of the foot, it's normal speed (24fps) and when the kick lands it's cut down to %50 for like one second, and then right after that, it ramps back to normal speed (24fps).

That's basically what I'm talking about.
 
i think barry used 48 for slow motion, because when divided, it divides equally back to 24. If you shot 60, you would have to mess around with the speed up to make it look like 24 again. Making any sense? Good luck! If you need help, I can always show you later.
