Thank you that helped (esp. channelsplit).

ffmpeg -i sintel.mpg -an -filter_complex "[0] scale=1000:1000,split=2
[a] [b]" -y -map "[a]" sintel.avi -map "[b]" sintel2.avi

seems to accomplish my original goal. Sweet!

My suggestion for the documentation would be to add "trivialized"
FFmpeg command line examples to the "Simple filtergraphs" and "Complex
filtergraphs" sections, or point the "Complex filtergraphs" section
with a link to where it describes filter_complex, and add a "single
input, multiple output" example command line there.  Something like
that anyway.
