Yes.

ffmpeg -i in.avi -c:v ffvhuff -c:a copy out.nut -f image2 out%d.png

You can even do super-cool things like only take one frame per second:

ffmpeg -i in.avi -c:v ffvhuff -c:a copy out.nut -f image2 -vf
fps=fps=1 out%d.png

There are also extensive docs one can use to get familiar with the
ffmpeg command syntax and/or discern what ffmpeg can do.
