Blackmagic Design CONVBATT/HS overview

  • 1Description

The Blackmagic-Design HDMI to SDI Battery Converter converts an HDMI input to up to two SDI outputs. The outputs automatically match and output in the quality of the HDMI input, whether HD or SD; whatever comes in is what automatically goes out. Both the HDMI and SDI connections support up to 1080p60 HD, which on the SDI side is equivalent to 3G. The converter also supports embedded audio on both the in and outs.

One reason for converting to SDI is to take advantage of the longer distance that SDI cables can carry a signal. If your camera has an HDMI output, this converter will let you instead output by SDI, allowing professional connectivity on location.

Power is supplied by a built-in lithium-ion polymer rechargeable battery that allows on location work without external power, and an AC power supply is additionally also included.

Sophisticated Conversion
  • Converts an HDMI input to up to 2 low-jitter SDI outputs
  • Conversion allows the use of longer professional SDI cables
  • The SDI outs auto-match the SD / HD quality of the HDMI input
  • Both the HDMI and the SDI connections support up to1080p60 HD
  • Audio embedded on the HDMI in goes out embedded on the SDI outs
Battery and/or Adapter Power
  • A built-in battery provides more than 2 hours of charge
  • The battery can be recharged while the converter is in use
  • A toggle switch allows you use the battery only when needed
  • An LED indicator displays what the charge level of the battery is
  • An adapter is included for external power and to charge the battery
Super Tough Design
  • Machined of aircraft grade aluminum
  • Can be run over by a truck and still work
  • Small enough to fit into the palm of a hand
  • Scratch-resistant labels / non-slip rubber feet

    Blackmagic Design CONVBATT/HS reviews

    HDMI to SDI Battery Converter is rated 4.3 out of 5 by 20.
    Rated 5 out of 5 by from Exceptional performance & build quality. This particular product I am using to capture the HDMI output of an HD remote-controlled camera. I've had trouble with its HDMI signal not being detected by some equipment (e.g. it ingests fine on a BMD Intensity Pro but the BMD DeckLink doesn't even detect it - really annoying), but this converter detects it perfectly and then I feed it into my BMD ATEM 1 M/E switcher. The setup works beautifully. I can't wait to use this converter in a different setting. Runs as easily on AC as it does on DC (built-in battery), which it lasts a long time on. And I'm quite sure you could probably run it over with a truck and not worry :)

    Rated 5 out of 5 by from Solid as a Rock We use these on several cameras with HDMI output and just velcro them to the tripod legs. They drive long RG6 lines in the studio and are 100% solid. We've never had a single problem with them. We also use these to convert downscaled 480i HDMI out of a computer into SD-SDI. These actually replaced some low cost products that were unreliable and flaky and again they have never given a problem in several years.

    Rated 4 out of 5 by from Fantastic Product Line My main focus is event videography / projection, and I recently added this to my SDI video switching kit. This allows me to connect prosumer cameras (HDMI) to my SDI switcher when necessary. Having a battery is a great feature when one of my operators needs to go handheld. The size, weight and build of the item is perfect for this as well. My one complaint over some of the competing units is there's no option to attach an external battery, so you're limited to the capabilities of the internal battery, which just won't cut it if you need to film for 3 or 4 hours on battery.

    Rated 4 out of 5 by from Tough, Easy, Professional No issues, battery life around 2 hours constant, strong signal when used with high quality HDSDI cable, allowed my shooters to move around freely and turn DSLR into IMAG prod cams.

    Rated 3 out of 5 by from Solid hardware, not-so-solid firmware I have two of these HDMI to SDI converters from Blackmagic Design feeding a BMD ATEM TVS. I purchased the converters a few months apart. The first works flawlessly with my Canon HFG10 video cameras. The second would not lock on the signal. It turns out the issue is with the latest version of the firmware. Downgrading to version 1.9 solved the problem. But downgrading is not obvious or simple. The firmware loader does not report the current firmware version or provide a facility for downgrading. Through trial and error it appears that only version 1.9 will install as a downgrade and solves the problem. The battery is a necessity for mobile cameras, but the integrated battery has limitations. It cannot be swapped for a fresh battery or replaced with a more powerful battery. In retrospect I would look closely at competing products such as the Atomos H2S that does have an external battery.

    Rated 5 out of 5 by from Works Well I am using this converter to go from the hdmi output of my HMC150 to the HD/SDI input on the atem1. I am running over a 300 foot 1505a belden cable. Works as intended. I love that I can run it off of battery or power supply. I haven't tested the length of time the battery will last yet though.
    Date published: 2014-01-06
    Rated 4 out of 5 by from Quality Product Great way to feed video to HDSDI monitors from camera that only have an HDMI output. Tough construction, works like it supposed to. Only criticism is that the internal battery only lasts 2 hours when fully charged.
    Date published: 2013-03-06
    Rated 5 out of 5 by from Awesome! Works wonderfully!!! I bought several of these to work with my ATEM TVS and HDMI camera's and it works great! Also, the build quality of these are SOLID. Much heavier and stronger than I imagined.
