An SPI3D file is a three-dimensional colour lookup table in the text format of Sony Pictures Imageworks, used by OpenColorIO. It starts with SPILUT 1.0 and lists output colours with their grid indices.
A CCC file is a collection of ASC CDL colour corrections in XML, each with slope, offset, power and saturation. It carries the grades of several shots between on-set, editing and grading tools.
