Which effect is commonly used for chroma keying in After Effects?

Keylight is widely recognized as the industry standard for chroma keying in Adobe After Effects. This effect allows users to remove a specific color (often a bright green or blue background) from a video, isolating the subject for compositing with different backgrounds. Its advanced controls provide precise adjustments for the keying process, making it effective for various lighting conditions and color variations in the background.

Keylight offers features like clipping, tolerance, and edge softness, which enable filmmakers and editors to tackle complex shots that may have uneven lighting or partial transparency. This level of control makes it the preferred choice among professionals for achieving a clean and convincing key.

While Chroma Key and Color Key are alternatives available in After Effects, they do not offer the same level of flexibility and precision as Keylight. Chroma Key is less commonly used and often lacks the advanced functionalities of Keylight, while Color Key operates on a simpler approach without the same depth of control for detailed adjustments. The Green Screen Effect is a non-existent specific effect in After Effects terminology, as it usually refers informally to the green screen technique rather than a specific effect within the software. Hence, Keylight stands out as the effective and preferred solution for chroma keying tasks in After Effects.
