It is not working. Terminal output below.

% ffmpeg -i Ducksinarow.mp4 -filter_complex 
"[0:0]drawbox=color=black:t=fill=enable='between(t,1.0,2.0)'" -c:a copy -c:v 
libvpx ducks.mp4
There should be a colon after fill, not =

drawbox=color=black:t=fill:enable='between(t,1.0,2.0)'
And for your next question that might come up (since you want to do multiple 
filters, I do too and just got bitten):
There is a limitation on Windows that won’t accept long arguments.

Do you have an example? I have used command lines _much_ longer than the above example, and never found a limitation.
