SmoothVideo Project (SVP) permits you to watch any video via any video player on your PC using frame interpolation, just like on high-end TVs and projectors.
It provides playback smoothness because it increases the frame rate by adding intermediate animation frames between existing frames to produce very fluid and precise motion - almost like you were standing in the scene. This technology is pretty well-known in the industry (TrimensionDNM, Motion Plus, Motionflow, and others), but now it's available to you using a simple GUI and a couple of mouse clicks. Yeah, even in 3D
By the way, the SmoothVideo Project (SVP) is not a video player, but it will allow almost any player to play smooth videos.
