It should work in a pipeline. What you are trying to is to encode it
with libx264, that's the part that doesn't work. You should be able to
note that, because you see the muxer complaining, and not the filter.
:-)

This works for me:
$ ffmpeg -y -f lavfi -i testsrc=size=1440x1440  -t 10 -filter_complex "[0:v:0]crop=1440:1:0:720[OUT]" -map "[OUT]" -f null -
and seems to produce a 1440x1 video stream (so I conclude that the crop
filter doesn't seem to have a restriction).

Expand your filter chain and let us know.
