Mini Converter HDMI to SDI 6G — Purpose
The Blackmagic Design Mini Converter HDMI to SDI 6G accepts an HDMI type A input and delivers two reclocked SDI outputs that automatically match SD, HD or 6G-SDI rates. It supports SMPTE 259M, 292M, 296M, 372M, 424M, 425M Level A or B and ST-2081 plus ITU-R BT.656 and BT.601. Video sampling is 4:2:2 with YUV colour space on SDI and YUV or RGB on HDMI at 4:2:2 or 4:4:4 precision. Audio includes four channels of AES/EBU digital audio and two channels of balanced analogue audio on quarter‑inch jacks.
Who This Suits — Who Should Look Elsewhere
Broadcasters and post‑production engineers who need reliable HDMI‑to‑SDI conversion for SD, HD, Ultra HD and DCI 4K formats up to 2160p30 will find the multi‑rate auto‑detection and reclocking useful. The unit also serves live‑event crews embedding external AES/EBU or analogue audio into the SDI stream. Buyers who require capture from copy‑protected HDMI sources cannot use this converter because the HDMI input rejects HDCP content. Users needing 12G‑SDI bandwidth or frame rates above 2160p30 should look at higher‑bandwidth models.
Bundled Accessories and Software Impact
A universal 12 V power supply with international socket adapters and a cable tie point is included, allowing operation from 12‑31 V DC at 4.44 W without sourcing a separate brick. Configuration and firmware upgrades are handled through the supplied USB updater application on macOS 10.12 Sierra or later and Windows 8.1 or 10, so no extra licences or tools are required to keep the converter current.

Questions about this item
What HDMI source do I need to connect to the type A input for the converter to work?
Any device with an HDMI type A output that is not copy-protected, such as a camera, recorder or computer graphics card, will drive the converter.
Will my existing SD-SDI monitor accept the signal from the two 6G-SDI outputs?
Yes — the outputs auto-detect and reclock SD, HD, 3G and 6G rates, so a legacy SMPTE 259M monitor will display the down-converted picture.
How can I verify the converter is passing 4:2:2 YUV video at 48 kHz 24-bit audio after setup?
Use the USB control panel on macOS 10.12 or later or Windows 8.1/10 to read the detected video standard, sampling and audio status reported by the firmware.
