Roland HDMI 4K Vision Switcher with Streaming (V-1-4K)

The Roland V-1-4K is a compact 4K video switcher designed for small to mid-scale live productions, from corporate presentations and house of worship services to educational streams and studio setups. It handles up to five HDMI sources with built-in scalers, supports 4K60 HDR processing, and outputs via HDMI or USB-C for plug-and-play streaming to platforms like Zoom or OBS. The switcher includes PTZ camera control, region-of-interest cropping to extract multiple virtual shots from a single 4K feed, and 14-channel audio mixing with professional processing tools. Whether you're running a multi-camera webcast or a hybrid event with graphics overlays, the V-1-4K delivers tactile control and flexible routing in a portable, all-in-one package.

Seamless 4K and HD Workflow

Every input on the V-1-4K includes a built-in scaler, so you can mix 4K and HD sources without format conflicts or manual conversion. This is particularly useful when integrating legacy cameras, laptops, or playback devices alongside modern 4K PTZ units. The switcher processes everything at true 4K60 with HDR support, ensuring high-quality output whether you're sending to a projector, streaming platform, or recording device.

Region-of-Interest Cropping

The ROI feature lets you define and crop specific areas from a single 4K camera source, effectively creating multiple virtual shots without additional cameras. This reduces setup time, camera count, and cabling complexity, especially in smaller venues where space and budget are limited. Use the V-1-4K Remote app to set up crop zones with visual feedback, then switch between them like individual camera inputs during your production.

Plug-and-Play USB Streaming

Connect the USB-C output to your computer and the V-1-4K appears as a standard webcam, compatible with Zoom, Microsoft Teams, YouTube, Facebook Live, and any software that accepts webcam input. No capture cards or additional drivers required. Stream in 4K60 or downscale to 1080p depending on your platform and bandwidth, with the switcher handling all encoding internally.

Flexible Output Routing

The V-1-4K provides six total outputs: five HDMI and one USB-C. Assign Program, Preview, and Multiview to dedicated monitors, then route outputs 3 and 4 to any bus or input signal via built-in 4K-to-HD downscalers. This eliminates the need for external distribution amplifiers or scalers when feeding confidence monitors, recording decks, or secondary displays.

PTZ Camera Control

Control up to five PTZ cameras simultaneously from the V-1-4K, with support for Canon, JVC, Panasonic, Sony, PTZOptics, Avonic, and VISCA-compatible models. Mix and match brands as needed. Use the V-1-4K Remote app on iPad to adjust pan, tilt, zoom, and recall presets without a separate controller, streamlining your production workflow and reducing desk clutter.

Graphics and Composition Layers

Three composition layers support picture-in-picture, titles, logos, lower thirds, and social media overlays. Use Roland's Graphics Presenter software (Windows) to design and trigger motion graphics, or load static images directly into the switcher. Layering keeps presentations visually engaging without requiring a separate character generator or graphics workstation.

Professional Audio Mixing

The V-1-4K includes 14 channels of audio mixing with EQ, compression, and sync delay on all input and output buses. This allows you to balance levels, process dialogue, and align audio with video without external mixers or post-production fixes. Analogue inputs via dual XLR connectors handle microphones or line-level sources, while RCA outputs and a 3.5mm headphone jack provide monitoring and feed options.

Customisable Control Pads

Eight user-assignable pads across four banks give you one-touch access to 32 functions, including input routing, audio mutes, PTZ presets, and Graphics Presenter triggers. Customise the layout to match your workflow, reducing reliance on menus or software clicks during live switching.

Remote Control and Software Suite

Roland provides free companion software for extended control and customisation:

• V-1-4K RCS for macOS and Windows offers full remote operation via LAN or USB
• V-1-4K Remote for iPadOS adds PTZ control and ROI setup with touch interface
• Graphics Presenter creates titles and motion graphics for live triggering
• VenuSet for iPadOS, macOS, and Windows provides customisable control interfaces

Compact and Portable Design

The V-1-4K retains the Roland V-1 series' portable form factor and intuitive layout, making it suitable for fixed installations and mobile productions alike. Tactile faders, knobs, and buttons provide hands-on control without relying on touchscreens or computer interfaces, which is particularly useful in fast-paced live environments where muscle memory and physical feedback matter.
