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

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.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

The VC-1SC-4K is proudly designed and manufactured at Roland’s headquarters and factory in Japan. Our growing 4K product lineup is made for today’s system demands, bridging modern 4K and HD workflows and allowing everyone to deliver engaging visual content at the highest quality.
