Roland announced the “VC-1SC-4K,” a high-performance video converter that supports 4K/60p. In recent years, video productions using high-definition LED screens have spread not only to large-scale events but also to small and medium-sized venues such as live music venues, multi-purpose halls, and showrooms, leading to increased demand for 4K-compatible video equipment.
The new VC-1SC-4K is a 4K/60p compatible video converter that features 12G-SDI and HDMI 2.0 signal conversion capabilities, as well as high-quality scaling. It can output video with optimal aspect ratio adjustments to match various sizes and aspect ratios of LED displays. It is said to support the construction of 4K video systems for event production and AV equipment with high reliability and intuitive operation.
Roland VC-1SC-4K – a 12G-SDI / HDMI 2.0 Bidirectional Converter/Distributor
The Roland VC-1SC-4K features 12G-SDI and HDMI 2.0 input/output terminals and supports bidirectional conversion. Resolution can be both up-converted and down-converted. In addition, regardless of whether SDI or HDMI is selected as the input, it outputs simultaneously from two SDI and two HDMI outputs, so it can also be used as a distribution unit.
Delay-free pass-through output
It features a pass-through output function that allows video to be output without going through a scaler. This enables system construction without worrying about video delay. The pass-through output function is available for both SDI and HDMI, and can be turned ON/OFF via the DIP switch on the unit or the control app.
Roland VC-1SC-4K Usage example
The 4K video output from the camera via 12G-SDI is converted to HDMI 2.0 and recorded by the recorder. A down-conversion function allows for simultaneous output of an HD signal for monitor display. 4K video output from the switcher is precisely adjusted to match the resolution of the LED screen using a scaler. Size and position can be adjusted in 1-pixel increments. Even when extracting content from 4K video and displaying it on multiple LED screens, the pass-through output function allows for system construction without worrying about video delay.
Control app that is also compatible with smartphones.
Checking the status of input and output signals and making detailed scaler settings can be easily done using the app’s graphical interface. The app is compatible with iOS, Android, iPadOS, macOS, and Windows, and can be used simply by connecting the installed computer or smartphone to the VC-1SC-4K unit’s USB Type-C port. Settings can be backed up in the app and shared across multiple VC-1SC-4K units.
Highly flexible audio input and output
It features two XLR inputs and two XLR outputs for analog audio. It can output audio from SDI/HDMI inputs as analog, or embed analog audio input into SDI/HDMI outputs. A patchbay function allows for audio routing changes. An audio delay function adds a delay of up to 3 seconds to the video output.
Supports various installation methods
Using the optional dedicated rack mount adapter RAD-3, it supports mounting up to three units per 1U of a 19-inch rack, including the AC adapter. It also features M10 screw holes, allowing it to be mounted on trusses, camera tripods, and other general-purpose clamps. Furthermore, it has slits for threading straps, enabling stable mounting in various locations, such as the underside of a display stand.
