Blackmagic Design Micro Converter BiDirectional SDI/HDMI 3G PSU

Blackmagic Design Micro Converter BiDirectional SDI/HDMI 3G (with PSU)

The Blackmagic Design Micro Converter BiDirectional SDI/HDMI 3G is a compact, broadcast-quality tool that effectively acts as two converters in one. It can convert SDI to HDMI and HDMI to SDI simultaneously, even if the two signals are in different video standards.

This model is limited to 3G-SDI, meaning it supports resolutions up to 1080p60 and DCI 2K60. The "with PSU" bundle includes a universal 100-240V AC power supply with international socket adapters.

Core Functionality

• Dual-Direction Conversion: You can convert an HDMI laptop or camera feed to SDI for a switcher while simultaneously converting an SDI return feed to HDMI for an on-set monitor.

• Camera Control & Tally: This is the converter's standout feature for live production. It translates Blackmagic’s SDI camera control protocol into HDMI. This allows you to use a Blackmagic Pocket Cinema Camera (4K, 6K, or 6K Pro) with a professional SDI switcher (like an ATEM Constellation) while maintaining remote control of iris, focus, color grading, and Tally.

• SDI Re-clocking: The 3G-SDI output includes built-in re-clocking, which regenerates the signal to reduce jitter. This ensures high signal integrity and allows for longer SDI cable runs without data loss.

• 3D LUT Support: The unit includes a 17-point 3D LUT engine. You can apply custom color calibrations or "looks" to the HDMI output, which is essential when using consumer-grade TVs as professional monitors on set.

Key Features

• USB-C Powering: While this version includes an AC power supply, the unit is powered via USB-C. This allows you to power it from a monitor’s USB port, a laptop, or a portable battery bank.

• Timecode Support: It preserves and converts timecode between HDMI and SDI, ensuring that all your devices remain in perfect sync for multi-cam editing later.

• Rugged Metal Design: Built with a durable metal chassis that acts as a heat sink, ensuring the electronics stay cool during continuous 24/7 broadcast operation.

• Automatic Standard Detection: The converter automatically detects the input video standard and sets the output to match, making it a "plug-and-play" device.

Technical Specifications

Operational Insight

In 2026, the BiDirectional 3G is the "bridge" of choice for HD productions. It is particularly popular because if you only have one input connected (e.g., just HDMI in), both the HDMI and SDI outputs function as loop outputs. This allows you to split your signal to an SDI switcher and an HDMI monitor simultaneously using just one small box.

Pro Tip: Use the Blackmagic Converter Setup utility via USB-C to switch between SDI Level A and Level B. If your signal looks "scrambled" or is not appearing on an older SDI monitor, toggling this setting usually fixes the handshake issue immediately.
