To be completely fair, that is actually in the docs, but it's not exactly on

Your thinking is invalid.
What part?
Is 'mi_mode=dup' or
adding realtime before the crop filter dropped the bitrate and increased
the encoding speed to 80x
i moved the realtime t filter after hwdownload, but the speed was still
about 1.78
I looked over the filter documentation:

Perhaps the character between 'mci' and 'mc_mode' should be ':' instead

That works for me
