WebJan 8, 2013 · Optical flow is the pattern of apparent motion of image objects between two consecutive frames caused by the movement of object or camera. It is 2D vector field where each vector is a displacement vector showing the movement of points from first frame to second. Consider the image below (Image Courtesy: Wikipedia article on Optical Flow ). WebAug 20, 2013 · Method 1: Speed up the clip, duplicate it manually and shift each by 1 frame, composite the layers. This would also allow for interesting effects (create more copies for a “trail” effect, less for less of a blurring factor). Publishing this would be tricky though. Method 2: Speed up the clip, use motion blur to interpolate. twinny salontafels – hpl plastica
