what is findaframeinterpolation fr?

FindAFrameInterpolation, or FAFI, is a free Windows video player built to make choppy video look smooth by generating extra frames in real time, so footage recorded at 24, 30, or 60 frames per second appears to flow at your screen's own refresh rate. It offers two different methods for creating those extra frames, a fast lightweight one always available and an optional neural network based one that produces cleaner results on tricky motion, and you can switch between them live while watching. Beyond video, the player can also load a music file and turn into a full-screen visualiser, with a gallery of animated visuals that react to the beat of the track, and you can switch back to picture playback at any time by opening a file or dragging one onto the window. Picture quality features include tone-mapped HDR playback on ordinary displays, high-quality upscaling, automatic correction of stretched aspect ratios, adjustable color and sharpness filters, and a set of retro visual style filters like CRT and VHS looks that can be toggled on or off. The player is designed to work entirely offline with your own local video files as its main purpose, with online video streaming included only as an extra convenience. According to the README, it sends no telemetry or background data of any kind, has no account requirement, and never disables any feature after a period without an internet connection. The only network activity it makes is one you trigger yourself, such as opening a streaming link or manually checking for updates. It is distributed as a Windows installer you download from the project's official releases page, installs without needing administrator rights, and publishes a checksum for each release so you can verify the download has not been tampered with. The software itself is closed-source and proprietary, free to use and to share unmodified, but the README states it is not for sale, not modifiable, and not to be reverse-engineered.
