-FFmpeg is not a great tool for colorspace conversion.

 Two options for building ffmpeg include:
 
-* [rocky-ffmpeg-8.1](docker/rocky-ffmpeg-8.1).
+* [rocky-ffmpeg-8.1](docker/rocky-ffmpeg-8.1), will build ffmpeg, oiiotool and OCIO (including the OCIO filter for ffmpeg).

 The combination of this and in_color_matrix will mean the color encoding will match the source media. If you are only adding one set of flags, this is the one, otherwise it will default to an output colorspace of bt601, which is a standard definition spec from the last century, and not suitable for sRGB or HD displays.

 # Conan Build System
 
+If you need a static build of ffmpeg, and do not need OpenColorIO, you may be quite happy with the [BtbN builds](https://github.com/BtbN/FFmpeg-Builds/releases/tag/latest).

 [Conan](https://conan.io) is a multi-platform C/C++ package manager. While its typically used to help build applications, it does provide a nice way to build mutiple versions of applications that can easily be run side by side. For example, you can have multiple versions of ffmpeg installed, and you can switch between them by running the conanrun.bat script in a shell.
 
 We have build profiles for MacOS, Linux and Windows.
