The --keep_asr option is no longer supported (IIRC, it was left in only
so people didn't get the even less useful "unknown option" message).
It looks like the tool you're using already calculates the proper frame
size (see the -Z option in the command line), so if you just drop the
--keep_asr things should work properly.
For reference, it's still possible to maintain the same aspect ratio
without calculating the size beforehand: just omit either the width or
the height from the -Z parameter (e.g. -Z x112 or -Z 200x), and the
omitted value will be automatically calculated based on the aspect ratio.
