Given my limited knowledge regarding video processing, I'm not sure I
fully understand what's meant here.
Does that mean: "fullpixel precision motion estimation, and
qpel-precision motion estimation on the winner macro-block?"

And here: "halfpixel precision motion estimation, and qpel-precision
motion estimation on the winner macro-block?"

Is that the same as "quarter pixel precision motion estimation"?

And finally: "quarter pixel precision motion estimation, and more
iterations around the winner macro-block" (maybe like increasing
libavcodec "dia" option?)

All that might be very brain dead questions, but I guess if I'm
puzzled regarding this kind of process, so are our dear "Joe Users"
