--optimize does nothing anymore. It used to enable a more aggressive
motion vector search. In my own experience it was actually harmful for
quality at a given bitrate, since the encoder didn't consider the cost
of encoding the motion vectors. Even if something feature is re-added
that controls the cost of the MV search it will probably come as a
speed-level knob, as the name "optimize" is misleading. (Perhaps an
optimize knob should rehuff?)
Sorry, I'm not familiar with "--grain" so I can't speak to the
prospects of adding it. Can you point me to a web page describing it?
