[MPlayer-dev-eng] An Idea - I cannot develop it. Scrap it if it is not any good.

That sounds like it would work pretty well... I do wish it would be 
possible to actually preview the ENCODED video while encoding, if it did 
MEncoder would be the first program on earth to support it. :) The obvious 
problem is the keyframing... Solution is to either decode the entire video 
which is wasteful or preview just keyframes which isn't very representative 
of the encode... :/

I'm interested.. I might add it to Kmenc15 some day.. assuming that I might 
some day actually add a line of code to that damn program. :P
