Overview

The Blackmagic Design Micro Converter HDMI to SDI 12G is a compact signal converter built for professional video production environments where HDMI sources need to be integrated into SDI workflows. It accepts an HDMI input and delivers two SDI outputs that automatically match the incoming signal, supporting the full range of SDI data rates from 270Mb standard definition through 1.5G, 3G, 6G, and 12G for Ultra HD and 4K content. An HDMI passthrough output is also included, allowing you to monitor the source signal while simultaneously feeding SDI to switchers, recorders, or monitors further down the chain.

Designed for simplicity, the converter requires no manual configuration — it automatically detects the resolution and frame rate of the HDMI input and adjusts accordingly. The unit ships with a 5V universal power supply that includes international socket adapters, making it ready for use in studios and on location worldwide. Its small footprint means it can be tucked behind monitors, mounted to camera rigs, or placed wherever space is limited without disrupting the production setup.

Pros & Cons

👍 Pros

Automatic signal detection eliminates manual configuration when switching sources.
Extremely compact form factor fits easily into tight production setups.

👎 Cons

Only converts in one direction — HDMI to SDI — so a separate converter is needed for SDI to HDMI.

The small size, while portable, means no built-in display for signal status monitoring.
Relies on an external power supply, which adds a cable to manage on set.
