Definition
A graphical element displayed on top of a live stream or video that provides additional information, branding, or interactive features to viewers. Overlays include elements such as webcam frames, donation alerts, subscriber notifications, chat displays, progress bars, and branded lower-thirds. For live streamers, overlays are a key component of stream production design — creating a professional, branded visual environment that differentiates the stream and communicates real-time information to viewers. Overlay design is a specialized skill within the streaming creator economy, with dedicated overlay artists and marketplaces.
