Guitar Oscillations Captured with iPhone 4

I just happened upon this trick when testing what it was like filming from inside my guitar. *Note this effect is due to the rolling shutter, which is non-representative of how strings actually vibrate.

Tips:
• You must have the strings brightly backlit to get the camera to capture at such a high frame rate (pure conjecture). You can see how the effect fades when the buildings come into view.
• Use a pencil
*This was used with the front facing camera, try the back camera, it may capture better! (tried it, it didn't look as good for me)

There is a heated discussion with *real science* over at reddit

*UPDATE here is the 'tracklist'
:14 - "Tears in Heaven" by Eric Clapton
:56 - "Signe" by Eric Clapton
2:57 - Snippet of "Tomorrow Land" by John Scofield
- the rest is just noodling around.

Also, I never thought I'd be known as a 'youtube guitarist', I just play for fun- I'm actually a motion graphics designer/animator. Check out http://www.justkyle.com

I'm so fucking high right now.

What's the song playing at 1:00?

[TheCinReds1]

tried this with my iPad...but my guitar wouldn't play after i cut a big hole in it to insert the iPad

[Bluddyshadowhell]

really ? wouldn't it be possible to create a program that can play wave oscillations or pictures of captured wave oscillations and be turned into a synthesizer

[Sebi20070]

this is not the waveform it is an effect called the rolling shutter effect. i can't deliver a in depth explanation but in phones and other digital cameras the shutter is not a thing that opens and closes and the picture is taken. it's a rolling shutter. each picture is divided is small parts like pixels and every part has it's own exposure time one after another and while the shutter is moving the string moves too due to its fast vibration and this causes this weird appearance

[Sniffer194]

Well maybe you'll explain that for us then...

[Sebi20070]

no! you can't.

[Sebi20070]

Ppl watching this video. As the uploader said in the description. This is NOT the way the strings actually behave. Read the description before commenting shit.

[Sebi20070]

wrong. this is not the actual waveform. why are ppl in the comments below this video so dumb? all murican or what?

[Sebi20070]

you souldn't you it. it's the rolling shutter effect, not a slowmotion picture of the strings moving. it's not the actual motion the strings do. if you knew enough about sound waves to deliver a lesson about that you wouldn't do this

[busvissla]

Just tried, it didn't work for me
