hey softypapa how are you. i am a big fan of your chennel. in my 4 new videos i have a chopper flying in the video. and you can see the top blades moving really slow like in this video. go check it out the name of that video is video 29 ben's flying video1.
go look at it becues i have the top blads of the chopper moving really slow like how the fans are moving in this video. hope you like the video. i like all your videos to. i am just very shy thats why i do not comment much
@softypapa The illusion of the fan blades spinning slowly is due to your camera's framerate. The human eye sees at about 60 frames per second while a video camera like yours can only record at a maximum of around 30 frames per second. Higher framerate = able to perceive or display motion in greater detail, so your eyes are seeing frames of the fans' spinning motion that your camera isn't.
If your camera lets you do it, decrease your shutter speed and increase your aperture setting. You may find that the fan begins to speed up. I think this does have to do with frame rate, since an optical illusion would be as obvious to your eye (optical) as it would be to the camera.
Our eyes are only able to capture images at a certain rate, so it gives the illusion that its moving slowly as we're only capturing the fan as it comes around in the same spots. Cameras actually capture images even slower, depending on how many frames per second the camera can catch.
Wow, that's something I've never seen before. When I was in Japan last summer, I saw lots of these fans among the apple and peach orchards. Though none of them were spinning rapidly like this, so I suspect they were wind turbines. Interesting.
The optical illusion seen in cameras and the like is called the Stroboscopic effect. It's pretty much used as a method to time reciprocating or revolving items like Internal combustion engines, mills, or turbines. The effect is caused by shutter speeds, not frame-rates. All in all, an amazing video as always.
There's a whole equation involved with the speed of things like fans, wheels on vehicles etc and the framerate of the device capturing it. That's why in many pre-lcd era movies a TV will actually just be blue, because an NTSC CRT runs at 30fps, and the camera captures 24fps, resulting in sickening flicker without modification.
The fans were moving so fast that your camera could only catch a few rotations/second.

the fans are going backwards in the video too right? Optical illusions are interesting.
Can you eat the tea leafs raw, does it taste good?

I didn't know it was an optical illusion. I always assumed it was the camera's frame rate.
I wonder if they have to worry about birds flying into those fans. That wouldn't be a pretty site to see.
You should get friendly with a farmer and make a detailed video about how the green tea is made ;-)

That optical illusion is really interesting to me. I would never think the fans were spinning fast, because they seem to move so slow.

Neat, right?

@TheGzeus By blue I mean they shot it with a blue screen and filled in later.
Glorious view, by the way.
*sigh* I'm unlikely to be seeing the lovely scenery of Shizuoka again any time soon.
