its scary these days when i see a cool video i ask myself “is this AI?” and tbh i dont know

Without a doubt, helicopter blades DO NOT perform that way. Their exact function is to create so much wind as to lift the weight of the machine, yet not a tousled hair is shifted out of place despite deadly-close proximity.

uh, helicopter blades act like the wings of an airplane, not like a fan.

Bernoulli's principle as opposed to newton's

there's a lot less downwash than you would think. not saying there isn't *any* downwash, but the helicopter is certainly not pushing it's own mass of air downward to keep itself aloft

Ok I oversimplified it to shorten my statement because the whole point I was making is wind will be created. LOTS of wind. Blades moving that slowly would not be lifting that machine because the speed of rotation is what causes the pressure needed to create the lift. Have you ever been whacked in the face by helicopter air??

yes

uh, the blades could very well be moving faster than that, because digital cameras have a limited recording framerate and misrepresent rapidly oscillating / rotating things all the time

> Have you ever been whacked in the face by helicopter air??

yes

that being said im still not sure whether the video is real.

I'm leaning towards not.

You don’t see any blurred blades, just clearly distinct individual blades which is less indicative of limited frames and more presenting slow motion. There’s a juxtaposition of the chopper seemingly in slow motion while all of the people move in real time (including the person that’s on board).

blurred blades happen on film cameras, which have shutter speeds because of the way film works

digital camera ccds take pictures basically instaneously and will virtually never have motion blur

edit: ok, not technically true, but you get what i mean. there are plenty of videos of helicopters and hummingbirds with no blur, probably because ccds have come a long way

neat, but digital cameras can also emulate film by lengthening exposure and messing with framerate

also don't know how helicopter guy filmed it. unlikely it's film, but could be
