after experimenting with slit-scanning and time distortion in videos for the past week, ive applied these techniques to create an audio reactive piece.
the main effect here is the data from the audio spectrum displacing slices of the video in time. the waves of audio data emanate from the center out symmetrically. id like to interpolate the peaks and troughs to form a nice wave like motion but i think the jittery effect works well with this track ( autechre - zeiss contarex ).

    thats really nice allready. Does it run realtime?
  • lukasz plus 1 year ago
    yeh all the frames from the video are first loaded into a frame buffer so it takes a while to load but once it gets going, processing can handle all the effects in real-time.
  • moka 1 year ago
    so you save all frames and the actual pixel distortions happen in realtime? or are you talking about an OpenGL FBO?
  • lukasz plus 1 year ago
    yeh sorry, the term frame buffer is a little misleading, thats just what i call it. i save every frame as a PImage and use the pixels. ive put up a link to the source if you want to check it out.

    also really liked your slit scanning/time distorsion experiments, specially the 'decomposing time' video. we're obviously interested in this kind of temporal manipulation of the image.
    you should really try and see rybczynski's "The Fourth Dimension". it has a lot to do with your works also.
    thanks for your comment!

    Do you have a sub-acuatic camera? ;)
