slowmoVideo using opencv calcOpticalFlowFarneback instead of the Nvidia GPU based V3D optical flow. It looks very good except for the higher speed motions- winsize probably needs to go up. The guy rotating on the ground looks smooth, but the higher velocity feet do not.
It only takes a few seconds per frame, not too bad compared to the gpu option (it was 2 seconds or so per frame), and not bad at all if you don't own a capable Nvidia card.
