Why shoot 30P?

I shoot two different ways on my DVX-100A; 60i for footage I plan on speeding up or slowing down ( especially miniatures) and 24PA for "film look". I'm wondering what applications might warrant shooting in 30P? What differences are there between 60i and 30P?
 
30P gives you a bit more detail, especially if you want to use freeze frames. 60i gives you smoother motion, but needs to be de-interlaced for reasonable look on progressive displays.

30P (or anything-P?) retains some of the film look, but handles certain types of motion a bit better than 24P.

Thanks, man. One more DVX mystery solved!

30P is also useful for 80% slow-mo in 24P projects. And lots of folks use 30P for straight-to-Internet material when they want the motion characteristics of 60i. Since Internet media is not interlaced, it avoids the need to deinterlace and thus drop half the info/resolution.

Only insomuch as it is progressive and not interlaced. Aside from that, the gamma curve adds to it. And if you shoot 60p and conform it to 24p for slow-mo, definitely.

But the DVX does not shoot 60p.
 
Depends on how you slow it down. If you slow it down to 80% on a 24p timeline, it'll look great. Not terribly slow, but great.

30% of what? 24fps == 30 fps * 0.8 Any other slowdown rate and you will either get interpolated frames or dropped frames.

Ok so help me understand. I want to shoot 30P and incorporate slo-mo. Not sure how much I need to slow it down. What workflow do u suggest? Pls be as specific as possible.
 
Assuming you mean you want to shoot 30p for slo-mo when the rest of your footage is 24p, you would edit on a 24p timeline, and then slow the 30p footage down to 80%.
