A movie file incorrectly converted by ffmpegX and captured from avidmux2 is the basis for this experiment in video and audio feedback.

I took pictures of myself using my Canon digital camera using a very slow shutter speed. The pictures were processed with OpenGL and converted in Max to a movie, which I then hacked with avidemux2 to add static and the compression error effects.
I recorded myself speaking a short text and loaded the audio into Max. By extracting the amount of motion from the video using frame differencing, I could map that number inversely to the sampling rate of the audio, so that my voice could only be heard in fragments of visual motion.

I created the audio for this piece using computer vision techniques, and the video was made out of analysis of the audio signal. Rubbing my finger over the camera produced a pitch, and then the zero-crossing of the resulting waveform are displayed in the screen on the top half of the screen. The camera’s output is displayed on the bottom half along with the zero-crossings of the second audio channel.
An animation I made using stop motion capture and after effects. Just a little something to get the creative juices flowing. It’s inspired by the 1878 motion capture photos of a horse galloping shown below.
