    I say this video is fake.

    3 main reasons:

    1) The frequency (seen in the video as distance between peaks and valleys) does not change much at all with the change in fretted note per each string up and down the neck. Neither does the waveform (which is incredibly unrealistic)

    2) The magnitude at which the strings are vibrating is so severe they would be colliding with each other and causing significant buzzing or noise

    3) The extreme right angles and other sharp angles the strings display in the video are completely unrealistic.

    People claim to have tried it and say it's real. I say it's a bunch of crap. It's either a complete creation using video software, or the effect of a digital artifact caused by the video software on the phone. What says you!?

    When you divide the vibration frequency by FPS (frames per second) all sorts of funny things appear. It's like wheels that slowly spin backwards in movies. Looks legit to me.

    I agree.
    FPS on video can do funny things.

    The distortion is probably caused by some kind of scan sampling type of delay error.

    We need to define legit.

    People are claiming this actually showing how strings move, with no digital manipulation and no software errors or additions. I don't think so. My belief is that this is either an out and out digital manipulation, or a video taken and posted with no manipulation by the poster that shows digital artifacts caused by the phone's software.

    Yep, rolling shutter effect. And I'm a genius, not a jeanius.

    This looks MUCH more realistic. Most of the wave forms are sine, which is closer to what you would expect. The waves in the other video look like someone playing with DC duty cycle or a fuzz box on a sillyscope. I mean really. Square waves with HF peaks? Doubtful.

    It's real. It's been here before. Cool stuff. It has something to do with the way the shutter operates on the phone, which is unlike a real camera. Or something. It's been a while.

    You're the biggest "jeanius" of them all, young man.
