However, Optical Flow, at least in FCP, does not uprez as Drew said, nor is it a stabilization plug in. Optical Flow smooths things out, whether for slow for fast motion, because it creates new frames in-between current ones rather than duplicating or blending them together which can cause the jerky stutter you see when you sped the sequence up.
Not every NLE has optical flow. In Final Cut Pro, I have never had the Optical Flow issues that Drew mentioned. All stabilization plug ins whether from Red Giant, CHV, Boris, Digital Anarchy or Apple work by rescaling which, as Drew mentions, and dependent upon how much stabilization is needed, works by upscaling. Upscaling more than 103% can reduce resolution. Just note that a stabilization plug in is a whole different thing from Optical Flow.
