The .3dl format stores a 3D Lookup Table (LUT) used for color grading and color transformation in video and film production. It defines how input RGB values are mapped to output RGB values, often used to apply a specific color look or convert between color spaces. It is commonly used in professional color grading software such as Autodesk Lustre and Flame, as well as other NLEs and grading tools that support LUT import/export.
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.
