Decimator MD-HX HDMI and SDI Cross Converter with Scaling & FRC

In this review the Decimator MD-HX proves itself as a practical, portable cross converter aimed at video professionals who need flexible routing and reliable format conversion on the go. The single biggest reason to buy is its multi-function capability: it combines HDMI and SDI conversion, scaling and frame rate conversion in one compact aluminum box, avoiding the need for separate converters or a laptop for basic configuration. The intuitive LCD and button control mean quick setup in live environments.

Key Features

• Multi-function conversion: Converts between HDMI and SDI and supports both 3G level A and B, so users can route mixed signal workflows without compatibility headaches.
• Distribution outputs: Four (3G/HD/SD)-SDI outputs allow the unit to act as a 1 to 4 distribution amplifier, useful for feeding monitors, recorders, and switchers concurrently.
• Flexible output routing: Output pair 1 can copy the SDI input or mirror pair 2, letting operators create duplicate or varied output streams without extra hardware.
• Audio mapping: SDI and HDMI audio pairs can be rearranged, making it easier to match downstream equipment and simplify multi-channel audio workflows.
• Onboard control and updates: The front LCD and buttons provide direct control without a computer, and the USB port supports control and firmware updates for long-term flexibility.
• Rugged portability: Aluminum case, locking DC power socket, and included power, HDMI and USB cables make it roadworthy for location and live streaming work.

Who It's For

The MD-HX is ideal for live-streaming crews, independent videographers, and broadcast techs who need a compact tool that handles SDI/HDMI conversions, scaling and frame rate conversion with straightforward local controls. Its versatility suits OB vans, small studios, and event rigs where space and simplicity matter.

Those who should look elsewhere include facilities requiring integrated switcher features or multi-channel up/down converters at higher density; this is a single-box utility rather than a full production switcher or large-format multi-converter farm.

Pros & Cons

Pros

• Combines multiple conversion, scaling and frame rate conversion functions in one portable unit, reducing kit size.
• Four SDI outputs provide easy distribution to multiple devices without extra splitters.
• Simple front-panel LCD and buttons plus USB control make field adjustments fast and accessible.
• Solid metal construction and included cabling add to its reliability on location.

Cons

• Not a multi-input switcher - it handles one HDMI and one SDI input, so larger multi-camera productions will need additional routing gear.
• Advanced users may prefer a software-based control suite for batch configuration if managing many units.
