Blackmagic Design ATEM SDI Pro ISO Production Switcher

Four-Input 3G-SDI Live Production Switcher

The ATEM SDI Pro ISO is a compact four-channel switcher built for multi-camera live streaming up to HD resolution. It combines switching, recording, and streaming in a single desktop unit with an integrated control panel. Operators can capture the program output and all four 3G-SDI inputs simultaneously as separate ISO recordings. A DaVinci Resolve project file is generated automatically for post-production editing.

Verify 3G-SDI Sources and USB Storage

Confirm every camera or source delivers a 3G-SDI signal at a matching frame rate and resolution before connecting. The switcher records ISO files to an external USB drive that is not included, so a drive with sufficient capacity and sustained write speed for multiple HD streams must be provided. Network streaming uses the rear Ethernet port, which requires a stable wired internet connection. Analog and embedded audio inputs are recorded alongside video, so check levels in advance.

Desktop Unit with Ethernet Streaming and ISO

The switcher sits on a desk or rack shelf and draws power from its included supply. Four 3G-SDI inputs accept cameras or playback devices, while the 3G-SDI program output feeds a monitor or recorder. Ethernet handles both live streaming to platforms and ATEM Software Control from a computer. USB-C connects the external recording drive. Two linear and luma keyers, an advanced chroma keyer, DVE transitions, and a media player are available internally without extra hardware.
