AJA UDC-4K SDI & HDMI Up, Down, Cross-Converter w/Frame Sync product description
Professional 4K/UHD Up, Down, and Cross-Conversion
The AJA UDC-4K is a rugged, broadcast-quality Mini-Converter designed for seamless conversion between 4K/UHD and 2K/HD video formats. Built on AJA's industry-leading technology, it functions as a versatile up/down/cross-converter, frame synchronizer, and 1x4 12G-SDI distribution amplifier. Supporting video formats up to 4Kp60, it is the ideal solution for aligning disparate sources in professional broadcasting, live events, and critical AV environments.
Superior Image Quality and Scaling
Utilizing advanced 12-bit conversion and a multi-tap polyphase scaling algorithm, the UDC-4K ensures maximum detail preservation and anti-aliasing. For interlaced sources, a motion-adaptive deinterlacer minimizes artifacts and motion blur. Whether you are up-converting 1080p to UHD or down-converting 4K for monitoring, the UDC-4K delivers pristine image fidelity without soft edges or ringing.
Integrated Frame Sync and Signal Distribution
The built-in frame synchronizer allows you to lock untimed 12G-SDI or HDMI signals to an external reference or the input itself. This ensures perfect timing for multicam productions. Additionally, the UDC-4K acts as a 1x4 12G-SDI reclocking distribution amplifier, allowing you to send processed or loop-through signals to multiple destinations simultaneously without signal degradation.
HDR-Aware Workflows and Connectivity
The UDC-4K is fully HDR-aware, supporting 10 and 12-bit signal processing with proper SDI VPID and HDMI Infoframe metadata management. It features 12G-SDI and HDMI 2.0 inputs and outputs, making cross-conversion between SDI and HDMI simple. The unit includes an onboard LCD display and push-button controls for standalone operation, plus USB-C connectivity for AJA Mini-Config software control.
