The Blackmagic Design MultiView 4 HD is a compact and efficient multi-display processor designed for live production environments where monitoring multiple video sources on a single screen is essential. It allows directors, technical directors, and engineers to view up to four different high-definition video feeds simultaneously in a customizable quad-split layout on one monitor. The device accepts video from up to six independent 3G-SDI sources, providing flexibility to connect cameras, graphics systems, media servers, and other production equipment. It features advanced frame synchronization on all inputs, ensuring that feeds with different timing or sources are perfectly aligned in the composite output without stutter or roll, which is critical for maintaining professional broadcast continuity.

Housed in a durable half-rack metal enclosure, the MultiView 4 HD is built for reliability in both mobile production units and fixed control rooms. Beyond simply arranging video windows, it enhances operational awareness by overlaying vital information onto each source, including user-assigned labels, visual tally indicators, audio level meters, and safe area guides. The composite multiview signal is output via both HDMI and SDI connections for maximum compatibility with various monitors and projectors. With its straightforward front-panel controls and optional software-based configuration, this device provides a cost-effective and space-saving solution for creating a comprehensive monitoring workspace, making it an indispensable tool for small to medium-sized live productions, broadcast studios, and streaming setups.
