Twixtor is a proprietary optical flow plugin for video editing software (After Effects, Premiere Pro, Vegas Pro). Developed by RE:Vision Effects, its purpose is to slow down video footage dramatically without lowering the frame rate.
How standard slow-motion fails: If you take 24fps footage and slow it to 10%, you get a choppy, stuttering slideshow. How Twixtor solves it: Twixtor analyzes two existing frames, guesses the "in-between" motion vectors, and generates brand new, artificial frames to create buttery-smooth 960fps+ results. kizumonogatari twixtor
Note: While "Twixtor" is the industry leader, free alternatives exist (e.g., Flowframes, DAIN, or RIFE in SwinIR). However, editors use "Twixtor" as a generic term, like "Google" for search. Paper Title: Temporal Dilation and Visual Fidelity: A

The problem? Most anime is animated on "twos" or "threes" (meaning one drawing is held for two or three frames). When you slow this down with Twixtor, the software has to guess where objects should move, often resulting in "warping" or "ghosting"—where limbs look like melting plastic.
