Blackmagic Design Mini Converter UpDownCross HD

The Blackmagic Mini Converter UpDownCross HD is a compact standards converter by Blackmagic Design that handles 3G-SDI up, down and cross conversion for broadcast, live production and studio workflows. A single box turns 1080p into 1080i, 1080i into 720p, or 720p back into 1080i — with a re-clocked SDI loop output and a simultaneous HDMI monitor feed. If you run a live production setup in Bangladesh and constantly hit format mismatches between cameras, switcher and projector, this is the converter that fixes it. Explore the full range in our SDI converters collection.

How to Use Blackmagic Mini Converter UpDownCross HD

Basic setup

Connect your SDI source (camera, switcher output, playback deck) to the SDI in port. Pick your output format using the front-panel DIP switches — each bank maps directly to a target standard (1080p50, 1080i59.94, 720p60, 525i NTSC, 625i PAL). Feed the converted SDI out to your downstream device, and keep the HDMI out patched into a reference monitor so you can confirm the conversion visually. The re-clocked SDI loop out carries the untouched original signal, so you can also record or monitor the native feed while broadcasting the converted one.

For live production

In a typical Dhaka live-production rack, the UpDownCross HD sits between a camera chain and an ATEM-class switcher, or between a switcher program output and a downstream record / stream deck. Pair it with a Mini Converter SDI to HDMI 6G to drive an HDMI-only monitor, or with a Mini Converter HDMI to SDI 6G when your source is a DSLR / mirrorless HDMI feed that must enter an SDI chain. For matrix-style monitoring of multiple cross-converted feeds, feed the output into a Blackmagic MultiView 4 HD. Teams building a bigger production pipeline usually move from converters to a full broadcast switcher rack once the camera count grows past four.

Configuration via DIP switch and software

All output formats are selectable through eight front DIP switches — the chart on the underside of the unit spells out each combination. For deeper tweaks (aspect-ratio behaviour, audio routing, conversion direction locks), connect a USB cable and launch the free Blackmagic Converters Setup utility on macOS or Windows. Firmware updates are delivered through the same utility, so the unit stays current with new input-format support.

How It Compares — UpDownCross HD vs Sync Generator vs SDI Distribution vs Teranex Mini

Blackmagic Design offers several Mini Converter form-factor units that look similar but solve different problems. Pick the right one for the job:

If your workflow is Ultra HD end-to-end, the premium Teranex Mini line is the correct upgrade path. If you only need to mirror one SDI feed to several destinations without changing the standard, the SDI Distribution unit is cheaper and simpler. The UpDownCross HD wins whenever the problem is format mismatch inside the HD family.

Care and Storage

• Keep the unit dust-free — blow out the vents periodically if it lives inside a gigging road case.
• Power down via the 12V adapter before re-patching SDI cables to protect the input stage.
• Use a branded Mini Converter Rack Shelf if you want multiple units in a 1RU rack — the chassis is built for it.
• Store the power adapter with the unit in a padded pouch; losing the 12V brick is the most common field failure.
• Avoid high humidity — silica sachets inside the case help for long storage in the monsoon months.

Frequently Asked Questions

What does the Blackmagic Mini Converter UpDownCross HD actually do?

It converts between SD-SDI, HD-SDI and 3G-SDI standards — up-convert 720p to 1080i, down-convert 1080p to 720p, cross-convert 1080i to 720p, plus aspect-ratio conversion (letterbox, pillarbox, anamorphic, center cut). One 3G-SDI input, one converted SDI output, one re-clocked SDI loop out and one HDMI monitor output — all live at the same time.

Does the UpDownCross HD support 4K or Ultra HD?

No. UpDownCross HD tops out at HD (1080p60 / 1080i / 720p) and SD (525i NTSC, 625i PAL). For Ultra HD / 4K conversion you need a unit from the Teranex Mini line, which is 12G-SDI and built for UHD workflows.

Can I down-convert 1080p to 720p with this converter?

Yes — 1080p to 720p is one of the core down-conversion modes. Set the target format via the DIP switches or the Blackmagic Converters Setup utility and the output SDI / HDMI will lock to 720p at the frame rate you pick. Latency stays low enough for live switching in most broadcast scenarios.

UpDownCross HD কি heavy live streaming এবং multi-camera production এ কাজ করবে?

হ্যাঁ। Dhaka-based live streaming studio, wedding videography team এবং church / mosque production এ unit টা well-tested। DSLR 1080p output কে 720p SDI তে convert করা, বা NTSC 525i archive footage কে PAL 625i broadcast feed এ match করা — সব কাজ single converter দিয়ে handle হয়। Re-clocked loop output থাকায় original signal এবং converted signal একসাথে use করা যায়।

How do I configure the DIP switches and use Blackmagic Converters Setup?

Each Mini Converter has a printed DIP-switch chart on the underside of the chassis — eight tiny switches let you pick input standard, output standard and conversion mode. For granular options (audio channel routing, aspect-ratio behaviour, processing amount), plug the unit into a Mac or Windows machine over USB and launch the free Blackmagic Converters Setup utility to tweak and save settings. Firmware updates come down the same pipe.

What power does it need, and will a BD mains adapter work?

The unit runs on 12V DC from the included external adapter. The box ships with international plug adapters, so standard BD three-pin and two-pin mains sockets are covered. Typical draw is low — roughly 6W — so it is safe to power from a UPS or a small power distribution strip shared with the rest of your rack.

Momi Enterprise থেকে এই converter এ cash on delivery এবং warranty পাওয়া যাবে?

হ্যাঁ। COD available সারা বাংলাদেশে, এবং importer warranty applicable। Dhaka র বাইরে ডেলিভারি সহ nationwide shipping আছে। Warranty claim process এবং exact delivery zone এর জন্য product page এর delivery estimator এবং sticky buy panel দেখুন — সেখান থেকেই current price, stock এবং ETA real-time দেখা যাবে।

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

The manufacturer part number is CONVMUDCSTD/HD. Use this MPN when matching with Blackmagic documentation, accessory compatibility lists (e.g. Mini Converter Rack Shelf) or when placing a B2B purchase order. The product name at Momi Enterprise is Blackmagic Design Mini Converter UpDownCross HD — both identifiers refer to the same SKU.
