OpenFX (API)

Current version is 1.5 as of December 2024. OpenFX was first announced on Feb 10, 2004 The Foundry Visionmongers. The OpenFX specification was written so that a plugin supporting the latest version of the API may be implemented to be compatible with a host implementing an earlier version. • OpenFX 1.0 was released in 2006. • OpenFX 1.1 was released in 2007. • OpenFX 1.2 was released in 2010. • OpenFX 1.3 was released in 2012. • OpenFX 1.4 was released in 2015. • OpenFX 1.5 was released in 2024. ==Hosts==

Free and open source plugins • The official OpenFX SDK (BSD license) contain sample plugins, programmed using the standard C API, or a C++ wrapper. • openfx-arena is a set of visual effects plugins, mainly based on ImageMagick. • openfx-io is a set of plugins for reading or writing image and video files (using OpenImageIO and FFmpeg), and for color management (using OpenColorIO). • openfx-misc is a collection of essential plugins, which provide many basic compositing tools, such as filters, geometric transforms, and color transforms. Commercial OpenFX hosts usually provide their own versions of these plugins. • TuttleOFX provides many plug-ins, especially for color grading, usable in most OpenFX hosts. • INK green/blue screen keyer and ChannelMath by casanico.com • TalentTracker by Mut1ny.com Commercial plug-ins • Beauty Box Video by digital anarchy • Color Symmetry • Composite Suite Pro, Film Stocks, Rays, reFine, zMatte, Tiffen DFX by Digital Film Tools • DE:Flicker, DE:Noise, RE:Match, Twixtor and ReelSmart Motion Blur by RE:Vision Effects • Dehancer OFX plugin for DaVinci Resolve and for Baselight by Dehancer • Film Convert for OFX by Rubber Monkey Software • Genifect by Dual Heights Software • HitFilm Ignite by FXhome • HDR Enhanced by AlphaPlugins • Lenscare and Flair by frischluft • RealPerception by Motiva • Neat Video by ABSoft • NewBlueFX plugins (including Titler Pro 3) • Primatte by Photron/Imagica • Red Giant Universe and Magic Bullet (in version 12.1, Looks, Film, Cosmo and Mojo are OpenFX plugins) by Red Giant Software • Sapphire Visual Effects OFX and Monsters GT VFX Plugins OFX by GenArts • White balance, exposure and color matching by FBmn Software • InviziGrain by InviziPro == Extensions ==

OpenFX' suite-based design enables one to easily introduce new sets of entry points, in order to cover other applications while still relying on the same core dynamic plug-in mechanism. A notable example is OpenMfx, an API based on OpenFX but meant to define procedural effects on 3D meshes rather than 2D images. A host that supports the Image Effects API does not necessarily support the Mesh Effect API, and vice versa, but both support the same core plug-in mechanism and basic suites like the Property Suite or the Parameter Suite. OpenMfx is an initiative independent from The Open Effects Association, led by Élie Michel since 2019. ==Documentation==
