I honestly assumed every codec makes much more sense than J2K because 
current implementations are incredibly slow (and x264 certainly 
offers superior quality).
Did you try FFmpeg's MPEG-4 ASP encoder?
(I would not even rule out the mpeg1video encoder without some tests.)

That is at least a surprise, but maybe they are using a better 
implementation than the ones I tried so far.

It is the container that was invented inside of FFmpeg, so it 
is possible not many programs except MPlayer and FFmpeg support 
it, but its specification allows to save all raw formats that 
FFmpeg supports, avi only allows a limited set of formats.
