wow, that helicopter video is really cool, but it does look kinda fake

WOW! I can imagine how it would be faked but it is definetly believable that it is real!

um... is that real or fake i can't tell!?

The helicopter is real, though not as much an illusion as the video seems. I thought it was cool, though.

So is the camera not picking up the motion of the blads or is it actualy stationary on wires ?

this one's more believable

i like the fan illusion

That video is pretty crazy

thats pretty crazy

You guys are not the brightest bulbs....it's the same type of illusion as the spokes or rims of a car. The blades are spinning at just the right speed that each frame of the video captures the blades at nearly the same rotation.

I blades of the helicopter are spinning at a rate which perfectly maches the cameras Fps.

i liked the middle picture best. the top one doesn't make any sense and the video looks fake!
But cool 'rotating' pic! it seemed to spin more when it was smaller.

there is no way thats real...when the helicopter begins to lift towards the end, the blade is spinning faster so we would at least see the blade move instead of being still the whole time. If the shutter speed was set to that of the blade when it just hovered, then it would not have the same effect when the blade begins to speed up

haha thats hilarious

Okay, so the only reason the copter looks like it's floating is b/c the shutter speed of the camera is the same as the speed of the propellar. That said, the video looks really great and whoever made it did a good job. I like it.

How can you think it´s fake!?! Naturally the rotation of the blades is perfectly syncronized with the frame frequency of the camera!! Haven´t you ever seen car tyres on a video going backwards?? It´s kinda the same effect...

it's real, the shutter speed on the camera is the same as the spin of the propellers....

laymans terms, every frame on the video was taken as the helicopter blades turned exactly once.


Cleverly done tho!

Hmm, the helicopter thing doesn't make any sense. Doing those maneuvers, the rotor speed would be varying, and not constsistently sync'd with the shutter speed. I say fake.

Looks fake to me, especialy at the end when the blades move down with gravity. So...yeah.

nOT EVERYTHING ISFAKE, some of you just are so stupid that you can't believe anything. why don't you get off the computer and go experience things in life. or maybe thats just fake to.....cock and balls

I think the helicopter illusion is real. It's the frame capture. For an example, on tv news- you'll notice that the computer monitor screen is out of sync due to frame capture by camera.

If you adjust the camera to right frame speed to match the speed of helicopter rotors, you may see the helicopter as if it "floats".

Hey Mr. Anonymous who posted this link: http://www.youtube.com/watch?v=mfXApFfMKuo

its really not. Don't know what your talking about.

The first photo is taken with a digital camera. These proces the info on their sensors line by lines (a bit like a TV works). If the subject moves fast enough, like it does here, it is captured several times as the image on the sensor is processed. hence the result.

That video was pretty cool. I doubt it was fake as you can see the blades rotate relative to the alignment of the helicopter as the helicopter as it does different moves implying the blades and camera shutter move slightly out of phase, which is what a lot of commentors argue is missing for it to be real...

Also thanks to the anonymous person who explained the propellers, I didn't understand that one at all.

its not fake... a helicopter's rotor speed will be constant while doing manuevers like that. Instead of the propellers picking up speed to gain altitude, the angle of attack of the blades increases and decreases to give it more or less lift.

I can't see the video, but I gather you are talking about a rotor that appears still on a helicopter during flight. Just an FYI; once a helicopters rotor is up to speed it varies very little, a pilot adjusts blade pitch and rotor tilt to move the vehicle. It is therefore very possible for the blades to be synched up with shutter speed (frame rate) during maneuvers.

This is actually very simple. the choppers rotors ARE moving. they just move at the same speed ast the cameras fps (frames per second). So this looks like the blades are not moving but they are.
This also happens frequently with the human eye, because the eye only registers vision at like 36 fps (i think, i could be wrong on this nuber). So the same type of thing happens.

I think you would have to have an incredible shutter speed to pull that off. But if you did and you got it just right it could work. The speed of the rotor does not have to change to pull those maneuvers. A chopper can gain the lift 2 ways. Change rotor speed (did not happen here) or change rotor PITCH. The rotors on that chopper can change the angle at which they hit the air. This is how they are able to have the rotor spinning at full speed and never leave the ground. Alter the pitch just a little and bam... They are gone.
