The operation of the glitch disrupts the algorithm to make its normally invisible operation suddenly visible.

Looking at codecs is interesting because they make values explicit. (Robert Ochshorn)

What is encoding?

mplayer debug 32 motion vector

-lavdopts <option1:option2:...> (DEBUG CODE) Specify libavcodec decoding parameters. Separate multiple options with a colon. 

      EXAMPLE:
         -lavdopts gray:skiploopfilter=all:skipframe=nonref

      Available options are:

 debug=<value>
      Display debugging information.
         0: disabled
         1: picture info
         2: rate control
         4: bitstream
         8: macroblock (MB) type
         16: per-block quantization parameter (QP)
         32: motion vector
         0x0040: motion vector visualization (use -noslices)
         0x0080: macroblock (MB) skip
         0x0100: startcode
         0x0200: PTS
         0x0400: error resilience
         0x0800: memory management control operations (H.264)
         0x1000: bugs
         0x2000: Visualize quantization parameter (QP), lower QP are tinted greener.
         0x4000: Visualize block types.

 vismv=<value>
      Visualize motion vectors.
         0: disabled
         1: Visualize forward predicted MVs of P-frames.
         2: Visualize forward predicted MVs of B-frames.
         4: Visualize backward predicted MVs of B-frames.
