ROLAND V-1-4K
The Roland V-1-4K is a 5-input HDMI video mixer (previous, program, multiviewer, scaler) of compact size and designed for live production in UHD resolutions. E s layer of managing multiple 4K and HD sources simultaneously thanks to its independent climbers per input, supporting different resolutions, color spaces and frame frequencies without requiring external synchronization. Internal processing works in digital domain with 4:4:4 and high color accuracy, ensuring signal integrity in professional environments, while HDCP compatibility and multiple HDMI formats expands its interoperability with cameras, computers and players. In addition, it integrates multiview output for simultaneous monitoring and efficient real-time signal flow management.
At functional level, the system has a composite engine with advanced keyers (chroma and luminance), configurable transition effects (cut, mix, wipe) and processing layers that allow operations such as picture-in-picture and graphic overlap. The embedded audio subsystem works with multi-channel digital mixing and DSP processing (equalization, dynamics and effects), synced with the video signal for streaming or live events. The interface combines direct hardware control — including T-bar — with remote control via software, which facilitates both manual operation and integration into automated systems. Together, the device is positioned as a compact 4K switching solution with multi-format processing capabilities and low latency oriented to light broadcast environments and hybrid production.
This mixer includes the ROI function (interest region) capable of generating up to 4 HD planes (assignable to channels) from 1 UHD-4K channel.
