The Roland V-1SDI is a compact, hardware-based live video switcher designed to provide straightforward and reliable switching between multiple SDI and HDMI sources in professional production environments. It supports four primary video input channels, accommodating a mix of 3G-SDI and HDMI connections, which allows for seamless integration of both professional broadcast cameras and consumer-grade media devices into a single production workflow. The switcher is engineered for immediate operation, featuring a simple front-panel interface with dedicated buttons for each source, transition controls, and a prominent T-bar for executing smooth manual fades. Its robust, all-metal construction ensures durability for both studio use and mobile applications in the field.

A central feature of the V-1SDI is its built-in multi-viewer output, which sends a composite display of all four input sources, the program feed, and a preview to a single HDMI monitor. This provides the operator with complete situational awareness from one screen, a critical capability in space-constrained setups like broadcast trucks, lecture halls, or small live event control positions. The unit also includes a basic downstream keyer for overlaying graphics or titles onto the program output. Despite its compact size, it handles full high-definition video signals up to 1080p at 60 frames per second, ensuring high-quality output for recording or broadcasting.

The switcher is designed for operational simplicity and reliability, making it an ideal choice for solo operators, educational institutions, corporate AV teams, and houses of worship. It requires no external computer or software, functioning as a standalone hardware unit that minimizes setup time and technical complexity. By offering essential switching, multi-view monitoring, and basic effects in a single, ruggedized package, the Roland V-1SDI delivers a dependable and accessible solution for creating professional multi-camera video productions.
