Human vision is more sensitive to brightness (luma) than color (chroma), so video systems often reduce color data to save bandwidth and storage. Chroma subsampling ratios such as 4:4:4, 4:2:2, and 4:2:0 describe how much color information is retained. 4:4:4 keeps full color detail, while 4:2:0 reduces color resolution significantly. Higher chroma sampling improves color fidelity and is preferred for professional editing, compositing, and green screen work. Lower sampling is common for streaming or consumer recording formats because it reduces file size. Understanding chroma subsampling helps creators choose formats that match their quality needs.

Chroma subsampling trades color detail for efficiency — knowing the difference protects image quality.
