The AJA HD10MD3 is a widely used downconverter capable of converting HD-SDI to composite and component video outputs for Steadicam applications.
The AJA unit accepts 5 to 18 volts DC, allowing it to be powered from standard 12-volt sources on a Steadicam sled.
RED cameras typically use non-standard mini-BNC connectors for video output, usually requiring either a mini-BNC to BNC adapter cable or an Element Technica breakout box to connect to standard downconverters.
The Redbyte Designs HD2SD is a compact alternative downconverter measuring 4 by 3.4 by 1 inch, operating on 12 volts DC, with features including auto-detection of HD formats and selectable 625i/50 or 525i/59.94 outputs.
BlackMagic's HD-SDI mini converter performs digital-to-analog conversion and HD-SDI to SD-SDI conversion but does not convert HD-SDI directly to composite video.
Power cable connectors on the AJA unit are prone to weakness from wear and rental damage, making custom power solutions with modified connectors or internal hardwiring preferable to standard connectors.
A multi-outlet power distribution box fed from the Steadicam sled's accessory power outputs can simplify powering multiple devices like downconverters and wireless transmitters.
