An SPI1D file is a one-dimensional colour lookup table in the text format of Sony Pictures Imageworks, used by OpenColorIO. It maps each channel through a curve, for example a log-to-linear transfer function.
A CDL file is an ASC Color Decision List: XML that pairs shots with ASC CDL colour corrections (slope, offset, power, saturation), used to carry grades between editing and colour grading applications.
