Micro Converter HDMI to SDI 3G (with Power Supply)

The Blackmagic Micro Converter HDMI to SDI 3G (with Power Supply) is a pocket-sized one-way HDMI-to-SDI converter by Blackmagic Design that takes an HDMI input from a camera, laptop, gaming console or capture device and outputs it on two re-clocked 3G-SDI BNC ports — up to 1080p60, level A or B. It is the practical bridge between the consumer HDMI world and professional SDI infrastructure: short enough to sit behind a camera plate, rugged enough to rack-mount, and SMPTE-compliant enough to land inside a broadcast chain. Buyers in Bangladesh should note two specifics — this is the HDMI→SDI direction only SKU (not bidirectional, not SDI→HDMI), and it ships with a +5V universal power supply in the box, unlike the USB-C-only bare-bones version.

How to Use Blackmagic Micro Converter HDMI to SDI 3G

Basic setup

Plug the HDMI cable from your source (DSLR clean-HDMI out, mirrorless, gaming console, laptop, capture card) into the converter's single HDMI input. Run two BNC cables from the 3G-SDI outputs to your downstream devices — typically one to a switcher program input and a second to a record deck or confidence monitor. Power the unit through USB-C, from the included +5V supply for studio / rack use or from a computer for quick field setups. The status LED will light as soon as a valid HDMI signal is detected; the converter auto-detects SD, HD and 3G-SDI standards on output, so no manual format selection is required on the SDI side.

Typical Dhaka live-production workflow

An example Bangladesh setup: a DSLR on clean-HDMI 1080p50 sits on a jib, the HDMI cable runs to the Micro Converter mounted on the back of the camera plate, and a 30 m SDI cable carries the re-clocked 3G-SDI feed to the control rack, where a Micro Converter SDI to HDMI 3G turns it back into HDMI for a Blackmagic Design ATEM Mini Pro Switcher, which has HDMI inputs only. A second BNC feeds a confidence monitor in the green-room. For ISO-record workflows where every camera angle must be captured separately, the Blackmagic Design ATEM Mini Pro ISO is the upgrade; it also has HDMI inputs only, so the same SDI to HDMI step applies. Wedding videographers, church and mosque livestream teams, and corporate AV houses in Dhaka and Chattogram can use this chain because it keeps long cable runs on SDI.

Powering the converter — included PSU vs laptop USB-C

The with Power Supply variant ships a +5V universal power supply with international socket adapters in the box; it powers the converter through the same USB-C port. Use the PSU for anything longer than a short rehearsal, or for any rack-mounted install, and tie its cable off so a kick on the cable run during a live show cannot pull it out. USB-C bus power from a laptop or a USB-PD power bank is fine for a field test, but note that if the laptop sleeps or the USB-C cable wiggles loose, the video feed drops instantly.

How It Compares — Blackmagic Micro Converter Family (4-SKU comparison)

Blackmagic Design's 3G Micro Converter line has three direction variants, plus a format-standards sibling in the Mini Converter family. Pick by what your signal chain actually needs:

If your entire workflow is already 4K / Ultra HD, step up to the 12G sibling — the Micro Converter HDMI to SDI 12G PSU pushes the same pocket form factor to 12G-SDI and 2160p60. If you need a larger-chassis converter with matching direction at 6G, see the Mini Converter - HDMI to SDI 6G. Buyers who also need standards conversion (1080p → 720p, HD → SD) should pair this unit with the Mini Converter UpDownCross HD — this Micro Converter only changes format (HDMI to SDI), it does not up/down/cross between video standards.

Why Pick This Over a Mini Converter?

The Mini Converter chassis is larger (aluminium brick, 12V DC, rack-friendly). The 3G Micro Converter family is newer and much smaller — a pocket-size housing that swaps the 12V DC adapter for USB-C power, with a +5V PSU in this variant. Pick Micro when you need the converter mounted behind a camera, hidden in a cable run, tucked into a gig-bag pouch, or stacked inside a portable flyaway kit. Pick the Mini or a Mini Converter - HDMI to SDI 6G when you are racking permanently and want the larger chassis for thermal margin and easier re-cabling. Both families share the same re-clocking and auto-detect behaviour on SDI output — the difference is form factor, 12V vs +5V power, and the top-end bit rate (Micro maxes at 3G here, 12G in the 12G variant; Mini chassis extends to 6G / 12G).

Care and Storage

• Keep the unit dust-free — blow out the HDMI port occasionally if it travels inside a gigging bag.
• Power down before re-patching BNC or HDMI cables to protect the input stage.
• Store the PSU with the unit in a padded pouch; the small adapter is easy to lose on site.
• Avoid high humidity — silica sachets inside the case help for long storage during the monsoon months.
• Terminate unused BNC outputs with a 75Ω cap when working inside tight racks, to keep EMI clean.

Frequently Asked Questions

Is the power supply really included in this SKU?

Yes. This listing is the with Power Supply variant — the box ships a +5V universal power supply with international socket adapters, in addition to the USB-C bus-power option. The USB-C-only variant (no PSU in box) is a separate Blackmagic Design SKU; if you need field + rack flexibility, buy this one.

Does Blackmagic Micro Converter HDMI to SDI 3G support 1080p60 and 4K?

1080p60 — yes, fully, along with 1080p24, 1080p47.95 and 1080p48 film rates; Blackmagic lists no DCI 2K for this model. 4K / Ultra HD — no; this is the 3G-SDI SKU. For 4K / 2160p60 workflows step up to the Micro Converter HDMI to SDI 12G PSU, which uses the same pocket chassis at 12G-SDI.

Can I use it with a Blackmagic Design ATEM Mini Pro Switcher?

Yes, with a converter at each end. The ATEM Mini Pro Switcher has HDMI inputs only, so it has no SDI input for this converter to feed directly. To run a camera a long way on SDI, put this converter behind the camera and a Micro Converter SDI to HDMI 3G at the switcher, so the source travels on SDI cable instead of a long HDMI run.

How long an SDI cable can I run?

Blackmagic does not publish a cable length for this converter. On 3G-SDI (1080p50 / 59.94 / 60) the usable run is shorter than at 1080i or 720p, and it depends on the cable: the re-clocked output helps, but cheap CCS (copper-clad steel) cable will glitch at 3G well before good cable does. Test the run with your actual cable before the show.

Does it pass embedded audio?

Yes, HDMI embedded audio is passed into the SDI output automatically — there is no separate audio port to wire.

What is the model / MPN to quote when ordering or for spares?

The Blackmagic Design manufacturer part number for the with Power Supply variant is CONVCMIC/HS03G/WPSU. Use this MPN when matching with Blackmagic documentation, accessory compatibility lists or when placing a B2B purchase order. The product name at Momi Enterprise is Micro Converter HDMI to SDI 3G (with Power Supply) — both identifiers refer to the same SKU.

Blackmagic Micro Converter HDMI to SDI কি 4K support করে?

না, এই SKU 3G-SDI — 1080p60 পর্যন্ত যায়, 4K / 2160p করে না। 4K / Ultra HD workflow এর জন্য Micro Converter HDMI to SDI 12G PSU নিতে হবে — একই pocket form factor, কিন্তু 12G-SDI এবং 2160p60 সাপোর্ট করে। 1080p তে চলা live-stream, wedding video এবং church / mosque production এর জন্য এই 3G variant-ই practical choice।
