Burning Question: What in the heck is OFX? #OFX #openfx
What is OFX?
OpenFX, or OFX, is a standardized software interface between the host and plug-ins for visual effects, editing, compositing, and finishing. It is now widely used for visual effects and video processing and is supported by numerous hosts such as Assimilate, Blackmagic Design, Digital Anarchy, FXHOME, NewBlueFX, RE:Vision Effects, and more.
Where did OFX come from and why?
The OFX API was established because each developer had its own proprietary interface, so developers at different companies couldn’t work together share code very easily. Developers had to create their own method of porting their plug-ins into each host, which, as you can imagine, can be expensive and time-consuming.
Bruno Nicoletti of The Foundry got things going in 2004. Some of the founding members were from Assimilate, Autodesk, Digieffects, FilmLight, The Foundry, GenArts, and RE:Vision Effects. OFX was transferred to The Open Effects Association (OFX) in 2009.
The OFX are proponents for open standards between developers of visual effects tools for supporting a broad range of platform-neutral hosts. The focus of the group is:
- to improve image processing
- lessen development costs
- shorten development time
- reduce product support that comes along with supporting multiple compositing tools and NLE’s
If you’re a developer, join the Association and get access to early releases and help shape future versions of the standard. OpenFX members collaborate with their peers to the developer and extend the OFX API, a BSD open source license.
Hosts that Support OFX Standard
If you use any of the hosts below, plug-ins that you use may support the OFX standard.
Let me first stress the point that if a plug-in is OFX, it does NOT mean that it supports all the hosts listed below. It just means that the following hosts support the OFX standard.
OFX is a standardized software interface for developing plug-ins that support multiple hosts. OFX is NOT a host or host platform.

Open Source hosts that support OFX
Below, a list of some of the plug-ins that already support the OFX standard. Undoubtedly, I expect this list to grow over the next year or two.

There is another OpenFX and OFX for 3D, which is very confusing and completely unrelated. Although the other one is also open source, it’s an unrelated Windows API for 3D and modeling.
