Well, for a few seconds of video, it shouldn't be a back breaker to
convert the clip to sequential frames (scriptable with mplayer), then
have a shell script extract the frames you want.  

However, the %difference stuff is something you'd have to write actual
code for (at least I don't know of anything available to do it for
free).  However, if you are going to get into writing that sort of code,
some research might produce methods with much better results.
