## Overview\abstract SCVideoEffectOutput
\discussion SCVideoEffectOutput represents a camera video effect session on a SCStream. Create an instance and add it to a stream using addVideoEffectOutput:error: to start the camera video effect. The camera preview is framework-managed and automatically added to the application’s key window. Callbacks for video effect lifecycle events are delivered through the SCStreamDelegate protocol.
