Pro Converter & Scaler Teranex Mini SDI to HDMI 12G

The Blackmagic Design Pro Converter & Scaler BMD-CONVNTRM/AA/SDIH is a media converter built for broadcast and production workflows that need SDI to HDMI conversion. It suits engineers and operators who require a compact Teranex Mini unit with automatic multi-rate switching. The device accepts SD, HD, 2K and 4K signals on a single 12G-SDI input and provides a converted HDMI output. It is not for buyers who need HDMI to SDI conversion or additional processing channels.

12G-SDI loop output and HDMI 2.0 limits

The converter includes one 12G-SDI loop output that passes the incoming signal through unchanged for downstream equipment. The HDMI port is a type A connector limited to the 2.0 specification with support for 2160p60, so higher refresh rates or newer HDMI features are not available. Analog audio is delivered as 2 channels of professional balanced output via XLR connectors, with the right XLR configurable for timecode output. Users needing more than two audio channels or different audio connectors must look elsewhere.

Teranex Mini 12G specification decides fit

The single specification that determines whether this is the right part is the Teranex Mini SDI to HDMI 12G designation, which defines the conversion direction, supported rates and physical interfaces. First listed by the manufacturer in 2018, the unit provides automatic switching between SD, HD, 2K and 4K formats without manual setup. If a workflow requires a different conversion path, a different Teranex model or a scaler with additional I/O is required.

Questions about this item

Should I pick the 12G-SDI model for my 4K workflow or will a 3G unit suffice?

The 12G-SDI input handles SD, HD, 2K and 4K with automatic switching, so a single unit covers every format up to 2160p60 without needing a separate 3G converter.

What does the 2160p60 rating on the HDMI 2.0 output actually deliver on set?

It provides a full 4K 60 Hz signal over a standard type A HDMI 2.0 connector, matching the 12G-SDI input frame-for-frame with no down-conversion.

How does the 12G-SDI loop output affect signal routing in a live chain?

The loop output passes the incoming 12G-SDI stream unchanged, letting you feed the converter and continue the same SD/HD/2K/4K signal to a recorder or monitor downstream.
