LUTs

Definition

LUTs, or Look-Up Tables, are mathematical formulas used in video editing and visual effects to map one set of colors to another. They play a crucial role in color grading by enabling filmmakers to apply a specific color palette or style consistently across multiple clips, enhancing the overall visual coherence of a project. LUTs help streamline the workflow by allowing editors to achieve complex color corrections quickly and efficiently.
