12G-SDI and HDMI Up, Down, Cross-Converter with Frame Sync

Rugged, compact, and designed for professional workflows, the UDC-4K is our most versatile Mini-Converter. The UDC-4K is a broadcast-quality Up/Down/Cross Mini-Converter that can seamlessly convert between 4K/UHD and 2K/HD video formats. Not only does it perform raster and frame rate conversions, but it can also function as a frame synchronizer and as a 1x4 12G-SDI DA, supporting video formats up to 4Kp60. With both 12G-SDI and HDMI 2.0 inputs and outputs, the UDC-4K makes SDI and HDMI signal conversion simple and efficient. Designed on AJA’s industry-leading conversion technology, the UDC-4K offers the highest-quality required in professional broadcasting, live events, and other critical AV environments. UDC-4K’s wide range of conversion possibilities makes it ideal for aligning disparate sources to a common format and timing reference, integrating legacy signals into higher resolution workflows, and handling many production challenges that may arise. It even offers utility frame rate conversion to convert 59.94 to 50/60 or 50/60 to 59.94 frame rates. The UDC-4K features 12G-SDI and HDMI 2.0 inputs, four 12G-SDI outputs, and one HDMI 2.0 output. The multiple SDI outputs function as a distribution amplifier, or DA, enabling the transmission of a clean or processed signal to multiple destinations. It offers SDI and HDMI loop outputs for simple confidence monitoring or pass-through to the next device. A reference input enables the UDC-4K to lock to an external reference, or it can lock to the SDI or HDMI input, providing frame synchronization capabilities for untimed video signals. It also offers the ability to convert 12G-SDI to HDMI 2.0 and vice versa with pristine image fidelity and support up to 60p for 4K/UHD. The UDC-4K is also “HDR-aware” supporting HDR workflows with proper SDI VPID and HDMI Infoframe metadata signaling management. The UDC-4K can easily be configured with its built-in button control panel and LCD display as a stand-alone device, or via AJA’s free Mini-Config software for Windows and macOS. These features make it the preferred solution for “all-in-one” Mini-Converter needs. The UDC-4K should be included in every professional AV, film/TV production, live production, broadcast, and DIT tool kit!
