what is purzos-ofx fr?

purzOS OFX plugins is a collection of 64 video effect plugins for professional video editing software, built using the OpenFX standard so they work inside DaVinci Resolve, Natron, and other compatible video editors. The plugins recreate the look of old analog technology and creative visual effects: retro pixel art, glitch and datamosh distortion, VHS tape artifacts, CRT television scanlines, color grades, and warped optical looks. Each plugin is written as a single self contained C++ file, sharing one small helper file for shared math, and compiled against the official OpenFX support library. Some of the plugins are ports of effects from an earlier web based project by the same author, while the rest were built specifically for this collection. Once installed, all of the effects appear together under a folder named OpenFX, then purzOS inside the video editor's effects browser. A key design choice is that every effect is deterministic: any randomness used in an effect is generated from a fixed combination of a seed value, the frame number, and pixel position, rather than a random number generator. This means the exact same render will look identical no matter which computer it runs on, which matters for splitting a render job across multiple machines on a render farm. Installation involves downloading a prebuilt archive for Windows, macOS on Apple Silicon, or Linux from the project's Releases page, then placing the plugin folders into the operating system's standard OFX plugin directory. Users without administrator access can instead point an environment variable at a custom folder. The plugins have been tested in DaVinci Resolve and Natron and are expected to work in any OFX 1.x compatible host application. The effects are organized into groups covering ported web tools, glitch effects, a full analog VHS signal chain, unusual optical looks like video feedback and phosphor burn, pixel art and dithering styles, additional glitch and datamosh effects, CRT and display simulation, and color and tone adjustments.
