About the Blackmagic Design 3GMC Bidirectional SDI/HDMI 3G Micro Converter

The Blackmagic Design 3G-SDI Micro Converter BiDirectional is a versatile, compact interface tool engineered to provide flexible signal conversion between HDMI and 3G-SDI video standards in either direction. Its primary function is to solve common connectivity challenges in hybrid video environments where equipment with different output and input interfaces must work together seamlessly. This small but powerful device can instantly convert an incoming HDMI signal from a consumer camera, laptop, or media player into a broadcast-standard SDI signal for long-distance cable runs into a professional switcher or recorder. Conversely, it can take an SDI feed from a studio camera or playback system and convert it to HDMI for display on a monitor, projector, or consumer-grade television, making it an indispensable adapter for a wide range of production and presentation scenarios.

Housed in a rugged, all-metal casing, the converter is designed for reliability in both fixed installations and mobile field kits. Its bidirectional capability is user-selectable via a simple switch, eliminating the need to carry two separate dedicated converters. The device supports high-definition video resolutions up to 1080p60 and includes advanced processing for critical tasks like embedding and de-embedding audio. When converting from HDMI to SDI, it can embed the HDMI's stereo audio into the SDI output stream. When converting from SDI to HDMI, it de-embeds the audio and outputs it via the HDMI connection. This comprehensive audio handling ensures that audio and video remain synchronized without requiring separate audio cabling or interfaces, simplifying the overall system setup.

Beyond basic format conversion, the micro converter includes features that address common signal issues. It offers re-clocking of the SDI output to clean up and extend the signal when used in chain configurations. The unit is powered via a standard DC power input, providing stable operation independent of the connected video sources. Its plug-and-play design requires no software configuration, allowing for immediate deployment. This combination of bidirectional flexibility, robust construction, and integrated audio processing makes the 3G-SDI Micro Converter BiDirectional a fundamental utility device for broadcast engineers, live event producers, and AV technicians, ensuring signal compatibility and enhancing workflow efficiency across diverse video systems.

FAQs about Blackmagic Design 3GMC Bidirectional SDI/HDMI 3G Micro Converter

What is the primary function of the Micro Converter BiDirect SDI/HDMI 3G?

This ultra-compact converter allows you to convert SDI to HDMI and HDMI to SDI simultaneously in different video standards. It bridges consumer HDMI devices—such as laptops, cameras, and monitors—with professional broadcast SDI equipment in both directions at the same time.

Does it support camera control and tally signals across conversions?

Yes, it supports camera control signals, tally, and timecode pass-through when used with Blackmagic ATEM switchers and compatible cameras. This allows you to control consumer HDMI cameras using SDI switcher signals or route tally indicators back to HDMI monitors.

What video resolutions and frame rates are supported?

Powered by multi-rate 3G-SDI technology, it supports standard-definition and high-definition video formats up to 1080p60. It automatically detects input video standards on both the SDI and HDMI ports and converts them independently.

What video input and output ports are built into the unit?

The unit features one 3G-SDI input, one 3G-SDI output, one HDMI input, and one HDMI output. It also includes built-in SDI re-clocking on the SDI output to restore signal integrity and reduce jitter over long cable runs.

How is the Micro Converter powered during operation?

It is powered via a standard USB-C port, drawing low-voltage 5V power from a computer, an external USB power bank, or the included USB power supply. The USB-C port is also used for connecting to a computer to update device firmware.

Does it feature automatic HDMI to SDI color precision scaling?

Yes, it automatically performs high-quality 10-bit video processing and precision color conversions between RGB HDMI sources and YUV SDI infrastructure. This ensures vibrant, accurate color fidelity regardless of signal conversion direction.

Is this converter small enough to mount directly on a camera rig?

Yes, its extremely small metal chassis measures approximately 3 x 2 inches and weighs less than 5 ounces. Its miniature footprint makes it easy to mount on camera rigs, tuck behind monitors, or slip into a pocket for field production.

Is a power supply included in the box?

Depending on the specific package SKU, it is available either as a standalone converter or as a kit including a universal 5V DC power supply with international plug adapters. Both configurations include a USB-A to USB-C cable for power connection.
