Sound and video on paperDistortion and degradation of audio and video through printing/scanning on paper
Video on paperI wondered how digital audio and video would be distorted and degraded if each frame were printed on paper and scanned.I wondered if it would look like film.... It does! It looks like really gritty and grainy film! The texture of the paper and of the ink really comes through, swirling and boiling along with the images which flicker and judder in the frame.
Sound on paperI also wondered if I could recreate the "variable area" style of waveform storage used in optical film soundtracks.It sounds really interesting - the character to the sound is something special and unusual - scratchy, hissy, and wobbling - mmmm my favourite!
Side-by-side original source and printed/scanned videoYou can download an [example video clip in flv format] or [example video clip in mpeg format].Note that this video is silent. Before-then-after original source and printed/scanned audioHere is an [example audio clip in mp3 format].You can also download the [waveform image] and [the scan that produced this sound].
Software for download:I've written some software to let me experiment with this approach; producing strips of video and audio for printing, and simplifying the process of scanning and re-assembling the information back into playable video and audio files. The software is not stand alone, it requires several other bits of supporting software to achieve the end goal. Details are lower down this page. [printScanVid.zip] - video distortion and degredation by printing on paper[opticalAudio.zip] - audio variable area printing (and scanning) All of this required extra software is open-source and easily available.
