What is a LUT?

• A. A color management profile
• B. A lookup table is a conversion chart that converts color values
• C. A video file format
• D. A mask for area selection.

Answer: (B)

A LUT is a Look-Up Table, a mapping that converts input color values to new output color values. It acts like a conversion chart: for each input RGB triplet, it provides a corresponding output RGB triplet, applying a specific color grade or transforming footage to a different color space. This lets you apply a consistent look or standardize footage from different cameras with a single operation.

The other options describe related concepts that aren’t about color-value mapping: a color management profile governs how colors are interpreted overall, a video file format is about encoding/containers, and a mask is used to isolate areas for editing.
