Overview
Luma refers to brightness or luminance values, while chroma represents color information. Video systems often separate these components for processing efficiency.
Why Separation Exists
Human vision is more sensitive to brightness than color, so many formats reduce chroma detail while preserving luma detail to save bandwidth.
Technical Role
This separation allows compression systems to reduce file size while maintaining perceived visual quality.
Professional Relevance
Understanding chroma vs luma is essential for color grading, compression, and broadcast delivery.
