Cool, but something doesn't seem quite right... like it isn't fast enough.

Ugh, my head.

It was probably filmed at 60 frames a second.

I think the reason it seems a bit slow is because it's a larger-than-normal hoop (the rate of time seems normal otherwise).

At the end the diameter of the hoop seems greater than her height. That's a really big hoop.

Also, the camera seems to be mostly opposite her and only occasionally rolling in against her. It might have been neater (though perhaps more dizzying) to counter-balance the camera on the hoop for a more natural in-and-out motion.

The poster on youtube said "maybe a little bit on the large side, but still a pretty normal sized hoop". And I think it's real time judging from the bit at the beginning.

So here's what I think is going on. Each time the girl spins within the hoop, that is in reality one rotation of the hoop. However, it takes at least six rotations for the camera to go around once. Start counting when the camera gets to her back to test this out. Subconsciously we're expecting the camera to go around her once for each hula, but that's not at all the case, because it's not really an orbit.

Aaaaand vomit.

AHA! That's it. You rock for that explanation.

Stare at one small section on the outer brim of a fan (preferably ceiling?) then after a bit, try to lock-on to a blade with your eyes and follow it. The fan seems to not be moving as fast as it appeared.

I'm still waiting for a 'Go Pro swallowed by a killer whale' video

AHHHHHHHHHHHH!!!!!!! F***ing Hipsters!!!!!!!!!!!!!!!!!

looks like Alaska

It has to do with the ratio of the circumferences of the hula hoop, and whatever is hulaing.

Vertiginous... bout fell outta my chair.

I couldn't tell if she herself was spinning around. I got very dizzy trying to tell.

@entr0py's explanation also accounts for why the camera goes around even slower when the hoop's on her neck -- the circumference of her neck is smaller than the circumference of her hips, so it takes more rotations to get one point of the hoop all the way around.

And of course this is a very wide lens, fisheye perhaps with almost 180° fov, movement seems alot slower with these..
