That's the first fountain I've seen that I would like to have.

Water, sound, and video frame rates. Also, always include the sauce OP. https://youtu.be/uENITui5_jU

Nope - it's real time. It's from a YouTube vid from a few years ago, where they even explained how it works... I'm sure you can find it :-)

Isn't it the cameras rolling shutter that causes this effect?

10 years ago | Likes 63 Dislikes 3

Good question! A rolling shutter effect would be seen as a disjointed or disfigured stream.

10 years ago | Likes 4 Dislikes 0

No. But this is also a type of sampling error. Rolling shutter causes a different class of errors.

Right, but cameras can produce several types of errors. Nyquist errors, as above, rolling shutters, and many others. Both Nyquist errors 1/2

10 years ago | Likes 5 Dislikes 0

and rolling shutters are classes of sampling error, but they produce different effects. 2/2

10 years ago | Likes 5 Dislikes 0

(As a rule, rolling shutter errors are still present when viewing a single still frame. Nyquist errors require a time-series.)

10 years ago | Likes 2 Dislikes 0

Mythbusters explain this. The gist of it, the hertz of the sound match the frame rate. In person it would look nothing like that.

So our eyes can't process the speed at which this happens?

So.. is this what dogs see on old tvs?

Why does the shadow sort of match?

This question is the reason we need better education and less pseudo science tv channels. Light speed = 300k km p/s

10 years ago | Likes 2 Dislikes 0

Had the same thought

10 years ago | Likes 1 Dislikes 0

Exact same reason. Shadow matches frame rate of camera.

10 years ago | Likes 1 Dislikes 0

The water probably does look like that in real life, but only for a split second at a time thus it wouldn't look like it in person. 1/

10 years ago | Likes 7 Dislikes 0

But the camera captures only those split seconds it is in that position so you get a constant shape effect 2/2

10 years ago | Likes 6 Dislikes 0

obviously a glitch in the matrix

10 years ago | Likes 1 Dislikes 0

Nope, that's due to 'rolling shutter'.

Do it really match?

10 years ago | Likes 1 Dislikes 0

@Telruin what about the shadow

10 years ago | Likes 1 Dislikes 0

Light moves incredibly fast. If water is at the same point for every picture taken, it stands that the shadow would also be the same.

10 years ago | Likes 1 Dislikes 0

So uhh, the noise just vibrates the nozzle?

10 years ago | Likes 1 Dislikes 0

This is called 'frequency folding' in sampling theory.

Thanks! Was starting to get my hopes up for a science experiment. Would not work well with young kids.

10 years ago | Likes 1 Dislikes 0

I will try to give a longer explanation. Imagine a metronome, set to a 1 second interval. Then you take a picture once a second. 1/x

10 years ago | Likes 1 Dislikes 0

Looking back the metronome would seem to be standing still. In the video the music is shaking the water, but it's still in the same 2/x

10 years ago | Likes 1 Dislikes 0

location for every picture taken, as the camera takes 25 pictures pr second, and the music "shakes" 25 times a second. 3/x

10 years ago | Likes 1 Dislikes 0

(The shadow is the same as light travel's incredibly fast, and if water is at the same spot, the shadow being made would also be the same)/4

You'd see the wave, but it would be falling full speed from the faucet - not seemingly freezing in place.

When used with a strobe light it CAN be seen in real life. Very cool effect

10 years ago | Likes 243 Dislikes 1

It's actually a big problem with florescent lights in shop environments. When bulbs flicker, moving saws can appear to stand still

10 years ago | Likes 152 Dislikes 1

Dont have all your lights on the same phase and make sure that atleast 2 phases are always on.

10 years ago | Likes 1 Dislikes 0

Hmm... sounds like an evil murder plan. Wire into the lights to flicker, to cause accidents... I wouldn't do that though

Such a weird thing to see. does 50hz ballast fix the issue?

10 years ago | Likes 17 Dislikes 0

50hz ballast exacerbates the issue. You need an electronic 20khz ballast. Switches so fast, the lamp never stops glowing. So any T8 or T5.

If the frequency of the strobe is the same as the framerate of the video, so no different really...
