Blackmagic Design ATEM SDI – Live Production Switcher

Product Overview

The Blackmagic Design ATEM SDI is an ultra-portable four-input live production switcher with 3G-SDI connections, built for multi-camera streaming and recording. It pairs the compact ATEM Mini form factor with broadcast-quality SDI cameras, adding a Fairlight audio mixer, DVE, chroma key, a 20-still media pool, USB webcam output, and the free ATEM Software Control.

Product Description

ATEM SDI provides four standards-converted 3G-SDI inputs and two SDI outputs, so you can connect broadcast cameras such as Blackmagic Studio Camera or URSA Broadcast G2 and live stream to YouTube, Facebook, Twitch, and similar platforms (or link back to a studio via ATEM Streaming Bridge). Each SDI input has its own standards converter and re-sync, so 1080p, 1080i, and 720p sources are automatically matched to the switcher format. The two SDI outputs are true aux outputs with camera control and tally.

The front panel has large source, transition, and audio buttons for switching by feel, with cut and auto transitions including mix, dip, and DVE squeeze/push, plus picture-in-picture DVE. A built-in Fairlight mixer handles all SDI inputs plus two 3.5mm stereo analog inputs for lapel and desktop microphones. USB acts as a webcam source for Zoom, Teams, Skype, OBS, and other software at 1080 HD. Behind the simple controls are full broadcast features — advanced chroma key, DVE, and still store — accessible through ATEM Software Control on Mac or Windows.
