A Micro Converter Designed for Modern SDI (12G) in the Blackmagic Range
The Micro Converter HDMI to SDI 12G belongs to the Blackmagic Micro Converters family: ultra-compact converters designed to quickly solve connectivity issues on set, in studio, or in control rooms. Here, the presence of 12G-SDI represents a genuine upgrade for current workflows, especially when working in UHD 2160p or 4K DCI. Whereas older converters were limited to lower SDI rates, this 12G version allows you to stay consistent with recent SDI infrastructures and maintain a clean chain ready for broadcast and post-production.
Another important integration feature: its two outputs can be configured as 3G-SDI level A or level B. This flexibility facilitates compatibility with SDI equipment that may expect different 3G mappings, notably in certain broadcast or live environments.
Who Is It For and What Are Its Uses? An HDMI to SDI Converter Tailored for Set, Live, and Integration
This converter is aimed at videographers, live technicians, integrators, and content creators who need to connect an HDMI source (compact camera, mirrorless camera, computer, media player) to an SDI environment (video switcher, router, SDI monitor, recorder, broadcast system). It is particularly relevant when cabling distance, robustness, or standardization require SDI, while retaining the flexibility of very common HDMI sources.
Thanks to its miniaturized format, it can be easily placed close to the source, behind a screen, on a camera, or in a mobile rack. And since it can be powered from a laptop or a mobile phone charger, it naturally fits into mobile setups without requiring complex dedicated power supplies.
