IMAG (short for Image Magnification) is the industry term for using live video cameras to capture close-up shots of performers on stage and display them on large screens—often LED walls or projection screens—so audience members farther from the stage can see details they would otherwise miss.

BUTTONS In multi-camera concert or event setups, the large panel of buttons you see is typically part of the video switcher. The Technical Director (TD) uses these buttons to select which camera feed or video source is sent to various screens or broadcasts. This real-time switching is how the TD controls exactly what the audience sees at any given moment.
