Which type of media does NOT usually use the technique of chroma keying?

Chroma keying is a visual effects technique commonly used in video production, often to replace a particular color in the footage with another image or background. This process is heavily utilized in various types of media, including video production, live action, and television shows, where it allows for more dynamic and visually engaging content by combining separate elements.

Animations, on the other hand, do not typically employ chroma keying. This is because animated content is usually created digitally, which allows for full control over every aspect of the visuals without the need to key out backgrounds as one would with live-action footage. Instead of layering different media by replacing colors, animations are crafted to include all their elements directly within the created frames. Thus, the absence of a physical background that needs to be keyed out makes chroma keying unnecessary in the context of animation.
