A CUBE file is a 3D Lookup Table (LUT) used for color grading. LUTs process a color value and output a corresponding value. These files can be used to manipulate saturation and contrast or completely change the color of a clip. LUTs are commonly used to create and save color grades that can be applied to give clips a unique style.
CUBE files can be exported from various color grading applications and imported into others. For example, Adobe Premiere Pro allows you to export color grading information as a .cube file for import into other color grading applications.
CUBE files can also be used in other applications such as Switchboard Canvas, a dynamic image API tool that creates images from responsive templates. In Switchboard Canvas, you can upload LUT files and apply them to Image elements to add a creative touch or apply consistent branding to different images.
