Chroma keying is a specific video editing technique that involves removing a particular background color from a video frame, typically a green or blue screen, and replacing it with a different image or video. This method allows for seamless integration of the subject in the foreground with various backgrounds, creating effects that are commonly used in film production, news broadcasting, and video games.

The popularity of chroma keying stems from its effectiveness in creating visually dynamic scenes without needing complex set designs. By using a green or blue screen, which are less common in human skin tones, editors can isolate the subject, making it easier to change the background without unwanted colors bleeding into the subject.

This technique is particularly valuable for visual storytelling, allowing creators to transport their characters or subjects to any environment in post-production. Therefore, option C accurately defines chroma keying's purpose and application within video editing.
