Blackmagic Design Micro Converter BiDirectional SDI/HDMI 12G

Blackmagic Design Micro Converter BiDirectional SDI/HDMI 12G

The Blackmagic Micro Converter BiDirectional SDI/HDMI 12G converts between SDI and HDMI in both directions at once, at formats up to 4K — so a single pocket-sized box solves the two most common problems on set and in studios: feeding an HDMI camera into an SDI chain, and monitoring an SDI source on an HDMI display, simultaneously. It even carries camera control and tally between Blackmagic cameras and switchers across the conversion.

Key features

• Simultaneous bidirectional conversion: SDI to HDMI and HDMI to SDI
• 12G-SDI supports formats up to 4K DCI 60p
• HDMI 2.0 input and output for cameras and displays
• Camera control and tally passthrough for Blackmagic systems
• Full SD, HD and Ultra HD format support with automatic detection
• Powered and updated over USB-C
• Broadcast-grade build in a pocket-size metal enclosure

Two converters in one body

Most converters go one way. This one dedicates a 12G-SDI input with loop output, an HDMI output, an HDMI input and an SDI output, all live at once. On a live production that means one device at the camera position can send the camera’s HDMI feed down SDI to the switcher while returning the programme feed to an HDMI field monitor — fewer boxes, fewer power supplies, fewer failures.

12G headroom

The 12G-SDI standard carries a full 4K signal on a single BNC cable — up to 4096 x 2160 at 60 frames per second — where older 3G chains needed four cables for the same picture. The converter detects formats automatically across SD, HD and Ultra HD standards and embeds audio through the conversion.

Camera control over the link

With Blackmagic cameras and ATEM switchers, control data and tally travel over the same SDI connection, so a camera converted from HDMI still behaves as part of the system — tally lights work, and the switcher operator retains camera control. That integration is what separates a broadcast converter from a generic adapter.

Problems it solves on real sets

A mirrorless camera with only HDMI joins a broadcast chain: the converter sends its feed down a long SDI run to the switcher — distances HDMI cannot cover — while its second path returns the programme feed to the director’s HDMI monitor at the same position. In corporate and worship installs it bridges legacy SDI cabling to modern HDMI displays without rewiring the building. Event technicians keep one in the toolkit the way they keep a cable tester: it is the small box that turns an incompatible connection into a working one, in both directions, at whatever format the day demands.

Choose the Micro Converter BiDirectional 12G if your world mixes HDMI cameras and SDI infrastructure: one rugged box that bridges them in both directions, at full 4K.
