Helicopter flying illusion, so, how ?

[Copiophonica]

maybe its using a different form of VTOL similar to what harriers use? You can see that the main rotor isn't moving when the body pivots. The propeller stays in place much like water does when you spin the glass it is in and the water in the middle stays stationary. You can see it turn slightly from the friction of the axel.. My theory is that it was using thruster VTOL.

[TheMightyHartley]

@Copiophonica It's a lot simpler than that. The frame rate of the camera matches the speed of the spinning rotors. That's it, really. A similar optical illusion can be seen on car wheels spinning fast - at night it can look like they're slowly tuning backwards.

[Centercourt57]

its not rope its the camera the propellers are moving so fast it looks still when lokking through a camera

[tesshess]

Ever hear of rope?

[TheMightyHartley]

@tesshess Yes, but what rope has to do with this video is lost on me.

[GunBroker100]

Better cameras have a frame rate adjustment. It easy to do this with a good camera. It's called optical synchronization.

[urmaan]

its signal processing problem .... its called Aliasing ... sampling frequency must be less than the frequency of the signal .... :P just read ..... in simple words the camera is s**t

[lolixization]

wtf?!



[cholasimmons]

Mocha Tracking :)

[BuXTYP]

SOVIET POWER!

[myndwork]

frame rates.

[SoulShifterx]

i would say its the frames on the camera

[elili96]

the helicopter is very small, the background is a picture of the sky, and the sound was edited.

the helicopter is atached to a string and the backround is moving and the sound was edited.

[Matty7159]

Guys, it's the refresh rate of the camera, not some stupid ass physics glitch or the wind... wtf?

[darkmessenger84]

It's gmod, the helicopter has hoverballs and thrusters attached

[southwest1998]

its because of the frames on your camera

[stu741zyphia158]

1. you can hear it so maybe its the camera.

2. it sounds windy so maybe it is so windy that there is enough for the wings to give it lift

[1tim64]

Its going so fast you cant see the blades go that fast

[songas333]

An error has occured. The program "ROFL COPTER.exe" is not responding

[EvilRides864]

Surely its being towed underneath another helicopter :S

[kaostwenty2]

thanks to the back one the pilot is still alive!

[AuzzieGamerzProdz]

LOL ITS LIKE BLACK OPS? REAL LIFE LAG AND GLITCHING

[LennyAndMike]

The FPS is not necessarily the same as the RPM of the blades. It only has to match any multiple of 1/5 of the blade's RPM.

[jbladel]

@LennyAndMike either that or this is just an jet engine helicopter

[CFGERProductions]

This is easy to make. get the turns per second of the blades approximately and set the cameras FPS to it. Voila - You have a flying Helicopter with not-moving blades. But the little back-rotor is turning in the video. Why? because its Slower of Faster than the main rotor. Easy isnt it :D

[TitanJoshy]

The fps is the same as the rate of the blades so it basically blanks it out therefore it isnt moving.

[JustCallmeLawson]

theres a glitch in the matrix

[blunaw1]

IN SHORT, THE FREQUENCY OF REVOLUTIONS PER SECOND OF THE HELICOPTER BLADES IS THE SAME AS THE FRAME RATE OF THE CAMERA.

[sexymeceye]

well my theory is the correct one trust me a video recorder takes a certan amount of snap shots per a second so when the snap shot is taken the properlors look like their not moving when in fact they are you see everytime the snap shot is taken the propelors are in the exact same place but they have rotated a full 360 degrees and the snap shot cort it in the same place as before but they did if fact rotate before the snap shot was taken i hope this helps you uynderstand

[tigertank10]

magic,chuck noris or a computer error on god's computer

[Elementboy6522]

My guess is that a single rotation (or a 60 degree integer) takes as long as it takes the camera to capture a frame. Thus it looks like the rotor doesn't move at all :P

[axedrecista]

Camera trick??? is a toy???

[TazeuX]

in soviet russia hinds don't need main rotor to fly

[hemicharger94]

@TazeuX then why does it even have it? lol

[TazeuX]

@hemicharger94 so it doesn't look different from the other hinds...you know..russian camouflage

[hemicharger94]

@TazeuX that is the smartest thing anyone's ever said

[Michael12794]

That's how I fly my chopper

[facepace2]

WAIT is it scary????????

[AlmightyMister]

The only ! reason you cant see the rotor spinning is because the camera takes exactly 1 shot every rotation of the rotor.

So when the rotor makes 1 rotation the camera takes 1 shot.. and so forward.

Generally the RPMs are around 120 to 400, so it takes a framerate of 120 to 400.

[gcoolceaser]

Looks like the work of filmmaking, Remember Godzilla and transformer, that type of camera trick. A small mini helicopter and camera angels to give the illusion. Then again it could be the great power of Mennow.

[majorszz]

Its wings have been disabled

[RandomUserName63]

The brain can only process a certain amount of "shots" per second, the rotor is spinning in such a speed that when the brain processes the next "shot" the rotor is in the exact same posititon as it was before, therfore it appears that the rotor isn't moving at all

[UkraineStar77]

@xeniosm I swear I wasn't trolling... I'm really that stupid -.-'

Sorry.

[marciovannelli]

[javalin597]

Silly helocopter, you're not a ufo

[TehKGBeast]

Hahaha, my Physics professor actually showed this video in our lecture today. There was a magnet that would relay each sub-rotation of the rotor to a camera which would then be exposed at that instant of time. Apparently they did this so they could study the distortion of the rotors under different maneuvers.

[SomeRandomGuy720]

240p... we meet again..

[agentHOTTIEMAN1]

I know how this was made. Look at the linked videos at the side. then look for flying car. Then look back to this video. The illusion is simple. They took a car shaped balloon and flew it around. Notice how both windows in both videos are tainted. that's because they don't want people to see how the trick is done. Sadly, people cannot go inside these vehicle shaped balloons other wise they would easily pop! I also forgot to mention that they use very small propellers on both sides of the balloon

[ingram182]

@agentHOTTIEMAN1 your an idiot... lol

[agentHOTTIEMAN1]

@ingram182 of course I am. And all the stuff I posted is a lie.-he says sarcastically-

[hazza22000]

@agentHOTTIEMAN1 no mate:L supremeon explained, sit back down.

[agentHOTTIEMAN1]

@hazza22000 just my opinion...

[doodle878]

Two top comments: A genious, smart comment explaining the science behind the video and a Chuck Norris comment, Youtube I am dissapoint.

[thevidmaster101266]

its the frame rate, and your camera (as same with mine) does not pick up the blur from the blades moving so fast, and your eyes do.

[rubiks56]

This is possible because u have a crappy camera. Thumbs up to move this to the top

[Clonecommander09]

[michael125333]

the helicopter is flying fine, but the camera just takes a frame everytime its in the same spot

[MrSurfer3001]

Oh there is a small get in the main body of the helicopter that helps steer and fly when the main blades aren't working

[t4nr]

It's an Air Hogs.

[jechet10]

Chuck norris was flying it.

[Meerkat218]

The helicopter is rotating at the same speed the blades are.

[theycallmejamesy]

@Meerkat218 uh.. not quite

[wolfman8448]

its the camera the shutter is too slow for the helicopter

[ODOriginal]

actually this is because the helicopters blades go to fast and the camera can not capture it

its called a strobloptic effect

[sealyboy1844]

@ODOriginal Dude, not even close. First of all it's stroboscopic effect and second of all the top comment has the right answer. The stroboscopic effect is a propeller "bending" effect.

[hawkerrose99]

someone needs to patch that thing..

[unihaza]

the frame rate of the camera is the same as the time it takes to sping once duh!! lol



[MrRRSmascara]

cheat codes

[cheesypo999]

Dear god, the russians have won! Adioss amigos! Canada here i come!

[DracoDarklove]

One of the oldest tricks of cinema... it's just a miniature.

[CRHAYNES123]

@DracoDarklove no the camera takes a picture at the same rate the rotors spin, so every time it takes a picture, they're nearly in the same spot

[Karsburg]

Resonant frequency of the camera with the frequency of the propeller ... Brazilian greetings, best wishes to all!

[Pivcuguivutra]

@Karsburg cheers!

[ppetepetepetepete]

@Karsburg since when do cameras resonate ??

[Blackops660]

Awesome hind damn russians

[Detonics451]

it's a toy imported in real soind hahahaaha

[aval1998]

note:SPECIAL EFFECTS

[NUBYER]

There's a massive stroboscope (the size of the sun) flashing at 260Hz which makes the rota look stationary.

[A1000wtp]

Lol awesome looking! -3 science!!

[ElvinDC95]

Hydraulic sistem.

[BadBoyArcher]

isent real



[Hawkflieslow]

Strobe effect the speed of the camera is the same as the main rotor so it appears to be standing still while the smaller tail rotor is moving much slower than it normally would. You can hear the chop of the rotor but can not see it move. slow down the frame speed or speed it up and it would appear to move. As is the camera is taking a frame every time the rotor is in the same location.

[ElementalJerk]

3 words. hidden jet boosters.

[pryroAsain]

the reason the rotors aren't moving are because the rotors are moving to fast or i'm just retarded

[nexus1g]

This is proof that helicopters don't fly; they're just so ugly the ground repels them.

[TAAVI322]

this is normal in russia...

[UrDadIsBent88]

it's a toy camera thats close to the camera and there ARE NO DOORS!! simple..

[Thundermuffin97]

@UrDadIsBent88 Duh there are no doors. ITS A GUNSHIP DUMBASS. you climb in through the window which opens like a door. Theres no space to use or need a door!!! Get you facts straight

[IMTHEDUTCHGUY]

@Thundermuffin97 hmmm why does the chopper has windows then? behind the cockpit, for goldfish.... or the 8 paratroopers it can carry....

`if you think with your ass you got shit for brains'

[RichardULZ]

people are saying frame rate but if the blades speed varies then the blades should appearer to go fast then slow then backwards.

[CrossfireV8]

@RichardULZ Helicopter rotor blades spin at the same speed, regardless of the maneuvers the helicopter is performing. The governor regulates the engine power to ensure the blades are always spinning at the same speed.

[todorroland]

fake



[nmted]

it is spinning so fast it looks like it is not moving

[poosanta]

@nmted Just like when im jerking it.

[supremeon1]

The frequency at witch the blades rotate is an exact multiple of the frame rate of the camera. For example, if you are filming at 22fps, than the blades of the helicopter can rotate exactly 2 times faster (44hz), or 3, 4 times faster, and so on:

[jman945x]

@supremeon1 RPM can't be measured in Hz. But you are correct.

[trojo90]

@supremeon1 super trippy right? lol im high and its like wowza

[ghpcaubo]

@supremeon1 FINALLY SOMEONE WHO USES HIS BRAIN. SUPREMEON THUMBS UP !!!!

[MythOfEchelon]

@supremeon1 Hz? I thought Hz was a measurement of frequency or CPU clock speed. Did you mean RPM? :S

[supremeon1]

@MythOfEchelon No, man, i didn't mean RPM!!! I couldn't, because Hz is the right word to use! I said, that, for example, the blades can rotate at 44 hz, that means 44 times in one second, not in one minute! So, stop using RPM, inches, feet and all sorts of "strange" measurement units.

[rg7488]

@supremeon1 44 rotationa per second equals 2640 RPM......just saying

[KFTteam]

Whet the F ????

[Shelbywuyutong]

It is interesting that so many people do not know that it is just about the camera...

[zZGoldenGamerZz]

I'm not going to give some nerdy explanation to this for 2 reasons;I dont know, and 2 its boring. I think they got a toy heli. and they attached strings to it. Its so close to the camera that it looks big.

[63v0r9]

@zZGoldenGamerZz retarded explication lmao

[zZGoldenGamerZz]

@63v0r9 Thanks?

[63v0r9]

@zZGoldenGamerZz always welcome :D

[ShustOne]

Come on people! The camera's shutter is set to the same rate as the helicopter's rotors. It makes the rotors appear to be in one position the whole time and creates this illusion. Voila!

[decoy2653]

I'd be willing to bet that it's a helicopter that is being held up by another heli. Rear rotar still on to make it look more real.

[bghon]

its running its power on nuclear fuels...

[geminiERAU]

this copter is clearly powered by charlie sheen

[testhossam1]

:) copter is a toy sound from outside scene

kr kr kr

[95erlend]

Omfg... This is filmed under-water. Why haven't anyone seen that until now?... just look at the rear-rotor. The rear-rotor is propelling the helicopter forward.

If u look closely you can see a small group of fish. If u look closer, u will bang ur head on the screen and realize u just wasted 15 seconds of ur life, which means you just lost 1:144000000 of ur life. (mathematically correct btw, if u reach the age of 72 years). Now if u read that last part, you lost another 15 seconds. 1:72000000sry

[GeoTown123]

@95erlend Well urm... There would be ripples.. colour would change? SOUND? You sill prostitute.

[mrmaxito17]

Chuck Norris was the pilot. 

[TheRealAskic]

It's the frame rate. Like when you point a camera at a computer screen.

[ToddlesROBLOX]

its a plane in disguise

[Snowfut2000]

Jets on the bottom LOL

[minimalhuligan]

the frequency of frames per second that the camera can capture matches the rotation of the main rotor of the heli... this isn't any illusion.... just a nice match between frequencees....

[MuchosDk]

Chuck Norris doesn't need rotors to fly a helicopter!

And of course -- co za asy!

[Protosfear]

The helicopter blades are oscillating at the same frequency and the machine it is being recorded on, hence the blades look stationary.

[Bra23we12]

@Protosfear

Not oscillating, rotating.

Stroboscopic effect.

A bit like the quantum probability wave. Not a wave....the leading edge of a rotational frame.

Ii's all just mass and movement. Energy and EM is bogus.

[xXPomfrittenPerXx]

Chuck Norris is in that thing !

[hellscruel]

You guys are retarded, have you ever seen a car driving and it looks like the rim's are spinning backwards? Same concept the framerate of the camera isn't fast enough so it doesn't look like it's moving at all at some parts you see the blade moving this is because of the blade speed is speeding up / slowing down

Thumbs this up for the Stupid people XD

[SuperSkatesteak]

ha ha ha its just a toy with sound effect

[afsere]

That helicopter is being carried by another one above it and the camera guy is moving around to make it look acrobatic. The sound you hear is the helo on top. No Jesus juice here.

[shizzka55]

@afsere your wrong sir. There is only one helicopter. Protosfear is correct.

[yummy791]

the rotor doesnt appear to move because it is going too fast.

[fireball31794]

this is so simple, its like putting a strobe light to a fan, the only difference is the strobe light here is the fps

[hunterziegelmann]

Dude we all know it is no illusion, for we also know that the man flying is... Chuck, Chuck Norris.

[nest1113]

Hax :)

[mana619]

V = 2*pi*R/T = film speed (frames per second) T = 2*pi*R/V , you could match it or go 1/5 times slower or any multiple of 5 will work because there are 5 blades equally spaced across PI.

[RicardoStephano]

@mana619  fkn nerd

[mana619]

@RicardoStephano

fkn engineer is what... a little math from mechanical physics. Have you heard of mathematics and physics before? Us nerds LOL.. Let's compare paychecks LOL... What a laugh. If you saw me at the gym you wouldn't say nerd, you would probably be intimidated. People like you are why the welfare system is still around.

[mytacotruxx]

@mana619 Ya See..Nobody Gets What The Hell You Just FUCKIN SAID!

[mana619]

Simple... The shutter speed of the camera was set to the same speed as the rotation of the blades. Shutter speed = V = 2*pi*R / T or 2*pi*R*f, where R = radius of one blade from center, f = frequency. Find the shutter speed to match time T. T = 2*pi*r / V

So if the blades are spinning really fast, which they are, and the camera shutter speed matches (or by cutting away T frames per 1-Revolution - 1-frame (the target)) then you still have a pretty good shot.

You can do this also by blinking.

[Drake14161337]

@mana619 Maybe but it looks like the blades start to spin when he turns.

[Drake14161337]

@mana619 Or does it just appear that way because the angle messes with things? You seem to know your stuff!

[abcd2393]

asians and their cheat codes.

[Badqualitygameplays]

I think it had thrusters aimed at the ground while the rotor didnt spin or somthing

[Darkfollower01]

because chuck norris is flying it duh

[TheEvilstonedmonkey]

@Darkfollower01 you should of put because chuck norris is fucking Darkfollower01

[01haggy]

What a fantastic video.

Another very skilled pilot showing off his skills, helicopter pilots are a breed apart, I am very jealous of anyone who gets to take the rotor ride every day.

[Raptor0348]

put your hands between the blades. Only true test ;)

[intigfx]

Bill O'Reilly: "How did it get there? You can't explain that!"

[pawningnoobsbaby]

say camera records at 25fps...

helicopter's blades spin at same speed of framerate per second...

RESULT: illusion where there's no movement.

it has nothing to do with frame rate or anything like that. the rotors don't move because it runs on Jesus' blood, and made from his bones. this is fact.
