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.
