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

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.

Editing 4 ways
- Editing by text/subtitle (Videogrep)
- Editing in browser
- Editing in patch (pd/gem)
- Editing in encoder (MPEG4 and relations to RMO's custom codec)...
