MotionPerfect can adjust the speed, frame-rate of run-time of an AVI video. It calculates motion within the video so all moved or newly computed frames have the right camera position and all objects have proper position. Make extreme slow-motion has smooth movement - no matter how slow. Change a frame rate to fill in gaps to change a jumpy low frame rate video into a smooth video. Change a run time to stretch or shrink a video to fit.
