Sideways: Slitscan for Urban Travellers

Sideways is a very small program created with Processing that creates 2 slitscan bitmaps from a single video. The video must be a first-person road shoot so both sides (left & right) are created from the edges.


  • open the sketch in Processing. Download the program if necessary
  • import your video to the sketch or place it in the /data directory
  • update filename and extension variables accordingly

important variables

  • scanBorderOffset is the sample distance from the edge
  • scanWidth is the slice width
  • widthFactor is the multiplier of the output width
