But, (and correct me if I'm wrong), the proper crop margins can only be 
determined after viewing the entire video (or at least a significant 
portion of it), unless there is movement along every edge of the video 
in the very first 2 frames.  So because of this, cropdetect needs to be 
run separately from the encoding, unlike autoaspect, which has all the 
information it needs as soon as the video is loaded.
