OCIOGen

is a minimal from-scratch OpenColorIO config generator. It has only one dependency: opencolorio.

All gamut conversion matrices are calculated from scratch using colorimetry math.

Install Dependencies

Make sure you have python version 3.7 or greater, then: python3 -m pip install opencolorio

Usage Instructions

Open ociogen.py with python. This will launch a very ugly but functional user interface as shown below:

You can

• enter the name of your config and the parent directory you want to save it into
• choose whether you want to create an OCIO v1.0 or an OCIO v2.0 config. 1.0 will use .spi1d LUTs for the transfer functions, while 2.0 will try to use built in camera log functions where possible.
• select the colorspaces you want added to your config
• choose the reference space (all gamut conversion matrices will be in reference to this colorspace, and all linear roles will be set to this)
• choose the reference log space (all log roles will be set to this, for example color_timing)
• click "Generate Config", and edit the result to add your own views.
