The Roland V-1-4K is a compact yet powerful video switcher designed to bring professional 4K production within reach of modern live workflows. Built around a streamlined and intuitive control surface, it delivers full 4K 60p HDR switching in an all-in-one solution that eliminates complexity without compromising capability. Whether used in live events, corporate environments, streaming setups, or hybrid productions, the V-1-4K offers the flexibility and performance needed to manage advanced multi-camera workflows with confidence.

At its core, the system features five HDMI inputs, each equipped with dedicated scalers, enabling seamless integration of mixed-resolution sources including HD and 4K signals. This allows operators to combine cameras, computers, and media devices without worrying about format mismatches, ensuring a smooth and stable production environment. The switcher provides multiple HDMI outputs alongside USB-C streaming output, allowing direct connection to displays, recording systems, or streaming platforms without the need for external converters.

The V-1-4K is engineered to simplify complex productions through intelligent routing and multi-view capabilities. With multiple assignable outputs and integrated multi-view monitoring, it becomes possible to manage program, preview, and auxiliary feeds simultaneously, all from a single compact device. This flexibility is further enhanced by built-in 4K-to-HD downscaling, making it easy to adapt outputs for different destinations while maintaining consistent image quality throughout the workflow. 

Advanced video processing is combined with creative tools that elevate production value. A three-layer compositing engine enables picture-in-picture, overlays, and integrated graphics, allowing operators to build visually rich scenes in real time. The powerful Region of Interest function adds a unique dimension, making it possible to extract multiple virtual camera angles from a single 4K source. This dramatically reduces the need for additional cameras while still delivering multi-angle production capabilities, making the V-1-4K especially effective for compact studio or presentation setups.

Beyond video, the V-1-4K integrates a multi-channel audio mixer with professional processing, ensuring synchronized and polished sound to match the visual output. Remote operation is supported via dedicated control software and apps, while built-in PTZ camera control enables seamless integration with modern camera systems. Combined with plug-and-play USB streaming functionality, the system allows direct connection to conferencing platforms and streaming software using standard webcam protocols, reducing setup time and technical overhead. 

Designed for real-world production environments, the V-1-4K brings together high-end functionality, flexible connectivity, and an intuitive user experience in a portable form factor. It delivers a complete switching, mixing, and streaming solution that scales effortlessly from simple setups to advanced productions, making it a central hub for anyone looking to create professional-grade video content with minimal complexity.
