I don't know whether VSR (video super-resolution, 
has been implemented in FFmpeg. I'd sure like to know.

VSR appears to use some of the techniques of motion-vector interpolation, but to employ the 
synthesized pictures to increase the apparent resolution of the existing pictures, instead. I 
haven't determined whether that increase applies solely to the pictures in key frames or to all 
pictures (contained in B & P frames, also) in a processing/filter chain.
