Blackmagic Micro Converters are incredibly tiny broadcast quality video converters that let you convert from SDI to HDMI, and from HDMI to SDI. The rugged, miniaturized design of Blackmagic Micro Converters makes them small enough to be used anywhere and conveniently hidden out of sight! You get HDMI and professional 3G-SDI connections for working with all SD and HD formats up to 1080p60, along with power over USB, so they can be powered by big screen televisions or laptop computers without having to plug them into the wall! Blackmagic Micro Converters can be purchased with or without an external AC power supply so you can choose the model that fits your needs!
