Blackmagic Converters are small broadcast quality video converters that let you convert from HDMI to SDI. The rugged, miniaturised design of Blackmagic 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.
