The Blackmagic Design SDI to HDMI Mini Converter is a compact, portable, and reliable device designed to bridge the gap between professional SDI (Serial Digital Interface) video sources and consumer or prosumer HDMI displays. It's a fundamental tool in video production, broadcast, and live event workflows, allowing users to connect cameras, switchers, or recorders with SDI outputs to HDMI monitors, projectors, televisions, or capture cards. Its miniature, bus-powered design makes it incredibly versatile for field use, studio setups, and fixed installations where space and power are at a premium.

This converter is built for quality and simplicity. It accepts a standard SDI input and provides a scaled and converted HDMI output. A key feature is its advanced scaling engine, which allows it to handle various input formats (including SD, HD, and up to 3G-SDI for 1080p60) and automatically scale them to match the connected display's native resolution via EDID communication, or to a manually selected output format using dip switches. It also handles audio embedding, converting embedded SDI audio and passing it as PCM audio over HDMI. The device is housed in a rugged metal casing and can be powered via the included USB power cable or directly from an optional battery pack, making it perfect for mobile rigs.

While it is a "mini" converter, it lacks some of the advanced controls (like frame rate conversion) found in Blackmagic's larger, more expensive converter models. Its primary job is straightforward format and connectivity conversion with high reliability. It is commonly used for confidence monitoring on set, feeding a client monitor from a professional video mixer, connecting a broadcast camera to an inexpensive field monitor, or ingesting an SDI feed into an HDMI-only device.
