DataMoshing

A complex technique where the movement in one layer of video is applied to another layer of footage, using lossy compression and removed frames to create a glitchy, psychedelic result. Think of what it looks like when your Netflix stream is dragging and creates a ghost image transition.

Technical Breakdown

  • So let’s say you have two clips. We’ll call them clip A and clip B.
  • Datamoshing is achieved by taking the P-frames from Clip B and applying that information to Clip A.  
  • In other words, datamoshing takes the picture information from one clip and combines it with the motion information from another clip. The result is that the movement of Clip B is translated into the image from Clip A. When combined, those “borrowed” P-frames from Clip B create visual artifacts in Clip A, giving datamoshing its distinct look.
