what's the dif btween slowmo in cam & shooting 60

[bgundu]

There is no difference in shooting 60p and changing the framerate to 24fps after.

Yep, what I just said. That is exactly what the HVX allows you to do.

Hey Jade 8472, i'm interested in your' theory about interlaced. For one i should say that i only asked about 60 p footage getting slowed down. So when i said progressive i meant 60 frames of it, not 24 or 30 which you came up with out of nowhere.

The HVX is currently the only camera capable of variable framerate at this price range. I was referring to when shooting with other cameras then 60i would be the way to go instead of shooting 24p or 30p and then slowing down in post.

Now there seems to be a debate of whether 60 i or 60 p is better for slowing down footage in post.

There is no debate, 60p in camera is better, period. For post production, see below.

The original question had to do with quality of in cam slomo, and the possibility of recreating it under optimum conditions in post, (having shot the extra frames).

60p requires no manipulation in post to give you slow motion. Just drop it in a timeline and you're ready to go. But there's not much more frame manipulation you can do to 60p either (for example if you want to slow it down beyond 50%). I'm referring to the fact that progressive frames cannot be interpolated to give you extra frames beyond what you shot. If your camera is incapable of shooting 60p, then shoot 60i and deinterlaced for (almost) the same quality slow-mo as 60p

But who says 60 i is really the way to go when aiming for post slomo?

No one. But if your camera can't do 60p then it is the only way to get decent slow motion. For example, on the DVX your option is shooting 24p, 30p or 60i. Try taking 24p or 30p footage and slowing that down in post; the result will be crappy. Take 60i, deinterlace to 60p and compare; it's going to be a night and day difference.

And how much better is it to have in cam slomo, when i'm starting to think that's a gadget intended for consumer reasons.

No, no, no. In camera slow motion is a professional tool, with many advantages:

1)Variable speed. Doing it in post as I've described and you're limited to 50% slowmo.
2) No loss in quality. Deinterlacing 60i to 60p cost you half your vertical resolution.
3) Saves time in post-production.

The best advice is to know what you're doing before you leave the house in the morning. P2 cards will last 2-2.5 times as long using native modes. If you're shooting 60p in a 60p timeline the only way to do slomo is in post. If you're shooting 24/30pn over 60 it's the same as 720/60. Shooting a whole 24/30pn project in 60p because you might want to do some slomo is going to diminish your storage by 2-2.5x. Prepro, it's making a comeback.
