A Micro-Format Evolution Designed for Modern SDI Workflows
The Micro Converter HDMI to SDI 12G follows Blackmagic Design's "micro" philosophy: offering compact, easy-to-deploy, and reliable converters for production environments. While many HDMI to SDI converters are limited to 3G-SDI, this 12G-SDI version is designed to support current UHD workflows while remaining compatible with HD environments. The result: an efficient bridge between HDMI sources (camera, computer) and a professional SDI chain (mixer, router, monitor, recorder).
Who Is This 12G HDMI to SDI Converter For?
This converter is ideal if you need to secure an HDMI signal for use in a broadcast or live event environment. It is especially suitable for video technicians, directors, content creators, and streaming teams who use HDMI cameras or computers but then work on an SDI infrastructure (long-distance cabling, patching, distribution, monitoring). Its miniaturized format also makes it very practical on set: it can be easily mounted close to the source and avoids fragile adapters or bulky converters.
