Question

What exactly is Motion Flow technology from Sony?

Answer 1

Motion flow is Sony's  name for 120 Hz frame rate with interpolated frames.  What that means is

Normal 1080p display shows a complete frame of TV (all 1080 lines) every 1/60 second. (60 Hz frame rate)

Motion flow adds an extra frame to increase the rate to one full frame every 1/120 second (120 Hz  frame rate)

There are two possibilities for that extra frame: duplicate the previous frame (easiest) or "interpolate", derive a new frame from information from both previous and next frames to position edges "in between" their locations in those frames.  The result is a smoothing of the apparent motion of objects.
