SlowMoVideo – Open Source Slow Motion Video Creator

SlowMoVideo is a free and open-source program that allows you to create slow-motion videos from your footage. It analizes the pixel rate and calculates the frames between the videos recorded by your camera. With SlowMoVideo you can smoothly slow down and speed up your footage, optionally with motion blur. slowmoVideo tries to find out where pixels move in the video (this information is called Optical Flow), and then uses this information to calculate the additional frames between the ones recorded by your camera.
