Title: Guitar Oscillations Captured with iPhone 4
Added: Jul 11, 2011
Author: justkylevids
Duration: 3:23
Description:
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 reddithttp://www.reddit.com/r/reddit.com/comments/in2rc/guitar_string_oscillations_captured_on_video/*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.

Mar 23, 2012 - For all those who actually care: The pattern is actually an alias generated by the sample rate of the video capture interacting with the vibrations of the strings. You can actually calculate the video frame rate by looking at the waveforms and knowing the frequency of the notes played. You can see the same thing if you hold the guitar strings in front of a tv. It is also the same concept that makes car wheels or helicopter rotors appear to change speed or rotate backward when viewed on tv.
