This B&H Kit
pairs the Blackmagic Design Mini Converter UpDownCross
with a Switronix Powertap Blackmagic Converter Cable
. The pairing opens up the use of the UpDownCross SDI conversion device in the field by converting the unregulated DC power from an existing Li-Ion brick-style battery with a Powertap output (not included
) to match the 12V power input of the Mini Converter.
The Mini Converter UpDownCross has several field applications. It accepts any SDI signal (HD, SD, 3G) with virtually any video format (PAL, NTSC, 720p, 1080i, and 1080PsF in most popular frame rates) and converts it to any other formats, with up to five SDI outputs (plus a loop-through output of the SDI input). Downconvert a camera's HD-SDI output to SD-SDI for SD field monitoring. Upconvert a camera's SD-SDI output for use on an HD-SDI field monitor. Convert NTSC to PAL or vice versa. Convert 720p to 1080i (or vice versa) for field recording of the proper video format on a HD-SDI recording device. The ability to use the UpDownCross as a format converter in the field should open up some creative possibilities for your production workflow.
Low SDI jitter enables long cable runs, and the UpDownCross device re-clocks the SDI signal for its loop-through output. This means the device also can be used as a simple SDI distribution amplifier, for relay to a video village, for example. The Blackmagic Mini Converter features a cable tie point that secures the power supply connection, thus preventing an accidental power disruption.
The kit's Switronix cable accepts a battery's Powertap output and supplies regulated 12V power to the Blackmagic Mini Converter, enabling its use in the field. The cable also features an inline female Powertap output (unregulated 11-17V DC power) for powering an accessory such as an on-camera LED light with a corresponding power input.
