Chroma key compositing is best described as which process?

• A. Also known as keying for green screens
• B. Color correction of skin tones
• C. Chroma key compositing is the process of removing a solid-colored background from a shot
• D. Retime a clip for slow motion

Answer: (C)

Chroma key compositing is the process of removing a solid-colored background from a shot so the subject can be placed over a different background. This works by selecting the specific color range (usually a bright green or blue screen) with a keying tool and making that color transparent, then layering the foreground over another image or video. That description captures the core action: taking away the background color to reveal a new background behind the subject. While green screens are common, the method isn’t limited to green. The other options refer to color correction or slow-motion editing, which are separate techniques and don’t describe chroma keying.
