The Blackmagic Design CONVMBHS24K is a compact, advanced format converter designed to seamlessly bridge high-resolution HDMI sources into professional SDI workflows, with robust support for Ultra High Definition 4K signals. This auto-switching mini converter takes the core functionality of its predecessors and elevates it to meet the demands of modern 4K production, automatically detecting and converting HDMI inputs up to 4Kp60 into corresponding 12G-SDI outputs. This capability is crucial for integrating consumer and prosumer 4K devices—such as gaming consoles, high-end cameras, media players, and computers—into broadcast trucks, live production switchers, and 4K routing infrastructure that operates on the SDI standard. Its automatic operation simplifies setup, as it instantly locks onto the source resolution and frame rate, outputting a pristine, compatible signal without requiring manual configuration.

Beyond its core 4K capability, the converter performs high-quality scaling and frame rate conversion, ensuring compatibility when the input and output formats do not precisely match. This allows it to down-convert a 4K signal to HD or SD for monitoring or distribution within a hybrid-resolution facility. The device handles embedded audio from the HDMI source, properly embedding multi-channel audio into the SDI output stream. It also incorporates professional features like bi-level and tri-level sync support for proper genlocking into a larger SDI system, ensuring stable, flicker-free video. Built into a durable, pocket-sized metal housing, the converter is designed for reliability in both permanent installations and mobile production kits, with minimal heat generation and straightforward operation.

Power and connectivity options enhance its versatility. The unit can be powered via a standard 5V DC adapter or directly from a USB-C port, making it easy to integrate into portable setups or power from a camera's battery pack. Status LEDs provide clear indication of power and signal lock. The Blackmagic Design CONVMBHS24K embodies a critical link in today's hybrid video production environments, solving the common but critical challenge of connecting the latest high-resolution HDMI devices to professional broadcast and post-production systems with transparency, reliability, and ease of use.
