Roland VC-1SC-4K Video Converter/Scaler

Professional 4K/HD Cross Conversion and Easy Video Source Adjustment for LED Walls and Other Displays
The VC-1SC-4K is a powerful and practical solution for modern LED wall applications, providing a versatile interface and easy screen adjustment for different display types. This compact, rugged device features built-in scaling, 4:4:4 10-bit processing, and 12G-SDI/HDMI 2.0 support for seamless cross-format conversion between HD and 4K sources. Using the dedicated multi-platform control apps, it’s simple to store/recall setups and adjust screen resolution, aspect ratio, ROI cropping, and much more.

Simplified Control for Modern Workflows
LED wall applications with various resolutions and non-16:9 displays are expanding in today’s production, commercial, and rental environments. The VC-1SC-4K is a highly adaptable interface that addresses modern needs where simple signal conversion is no longer enough. This robust, streamlined package delivers high-quality 4K processing, precision control, and fast setup in a variety of display scenarios, from live events to fixed installations and beyond.

Reliable and Flexible Conversion for SDI and HDMI Sources
The VC-1SC-4K is equipped with SDI and HDMI inputs that support 4K and HD signals at various frame rates, as well as a reference input for locking to a system clock. The powerful onboard engine provides stable cross conversion of professional video sources with premium 4:4:4 10-bit processing and full support for 12G/6G/3G-SDI and HDMI 2.0 formats.

Quick Layout and ROI Cropping
With its versatile video scaling tools, the VC-1SC-4K makes it simple to interface with a wide range of display types. Match your input source to the screen’s resolution with flexible size and position control. And use the ROI (Region of Interest) function to crop a specific area and get the most from non-16:9 displays.

Versatile SDI and HDMI Signal Distribution
The VC-1SC-4K easily handles video format conversions for maximum flexibility. Converted signals are output simultaneously on all video outputs (two SDI and two HDMI), allowing you to distribute video to multiple devices without extra hardware.

Pro Audio I/O with Audio Sync
The XLR balanced inputs and outputs on the VC-1SC-4K ensure reliable integration with professional AV systems. Embedded audio from the video inputs can be enabled or disabled, and there's also an internal delay function with up to three seconds of adjustment for syncing audio with video as needed

Built for Reliable Operation
The rugged metal design gives you a highly durable platform for all your production needs. Input and output terminals are well protected, and the chassis can be mounted via M10 screw holes. The compact profile allows up to three VC-1SC-4K units to be mounted in a single-space RAD-3 rack tray.

Powerful Configuration Tools
The VC-1SC-4K offers deep control options for all types of situations. Onboard buttons, selector switches, and dip switches present an efficient tactile interface for basic setups, while dedicated apps unlock much finer control via a high-speed USB-C connection.

Multi-Platform App Control
VC-1SC-4K apps are available for iOS, Android, iPadOS, macOS, and Windows, enabling comprehensive hardware control from mobile devices and desktop/laptop computers. An intuitive interface and three operation modes provide swift access to signal status monitoring, parameter editing, and custom configurations for every application.
Note: VC-1SC-4K control apps will be available in October 2026.

Status—Monitor Video and Audio Signals
Using the Status section within the apps, you can clearly monitor all video and audio signals to confirm your setup and troubleshoot problems instantly.

Editor—Complete Configuration Tools
The Editor section is the command center for configuring all the VC-1SC-4K's primary parameters. Different configuration areas are organized in tabs across the top of the screen for quick access, and each selected tab features clear controls for fast operation. The Layout tab provides precise control over input size and position, while the ROI tab lets you crop areas by dragging or entering exact values. The Color tab offers detailed color correction to fine-tune the look for venue conditions. And with the Audio tab, you can enable/disable embedded audio from the video inputs and control routing of the XLR signals. Test pattern generators are also available to aid in configuration and troubleshooting.

Library—Save, Recall, and Share Setups
In the Library section, you can organize custom configurations for the VC-1SC-4K, enabling fast setup for different applications and scenarios that require multiple units. Store/recall setups offline and on-site and easily share data with installation team members.

Elevate Productions with Roland Switcher Integration
Pairing the VC-1SC-4K with a Roland switcher like the V-1-4K expands your range for widescreen and LED wall productions. In addition, you can use multiple VC-1SC-4K units with the switcher to crop different regions from the same source and send unique images to multiple screens with no latency.
