Professional 4-Input SDI Live Switcher

The ATEM SDI Pro ISO is a portable broadcast switcher built for multi-camera productions that need integrated streaming and recording. Four SDI inputs with automatic standards conversion and frame re-sync allow mixed-format sources to be used without external converters. A hardware streaming engine sends program video directly to platforms over Ethernet, while simultaneous ISO recording captures up to five video streams to USB flash storage for later editing in DaVinci Resolve.

Verify SDI Sources and USB Storage

Confirm that each camera or source outputs an SDI signal the switcher can accept; the built-in standards converters handle format matching, but the source must still be SDI-compatible. For recording, use a high-speed USB flash disk or a powered USB hub with multiple drives to sustain the data rate of multiple ISO streams. Ensure your streaming destination accepts the Ethernet-fed output format and that network bandwidth is sufficient for the chosen bitrate.

USB Webcam Mode and DaVinci Resolve Project Export

The USB connection presents the switcher as a webcam source, letting any meeting or streaming software on a computer receive program video without a capture card. Recorded projects include a DaVinci Resolve timeline file, so the multi-camera edit opens directly in Resolve with cuts, graphics and audio tracks already placed, removing the need to manually sync ISO recordings.

Questions about this item

Does the ATEM SDI Pro ISO come with a USB flash disk for recording, or must I supply my own?

You must supply your own USB flash disk; the switcher records directly to any standard USB drive and also supports multiple disks through a USB hub.

Which video standard does the ATEM SDI Pro ISO use for its four inputs?

The four inputs are SDI with built-in standards converters and re-sync, so they accept a range of SDI formats without external converters.

What does the "ISO" in the model name mean for my post-production workflow?

ISO means the switcher records up to five separate video streams — program plus each of the four camera inputs — so you can re-edit the multi-camera production in DaVinci Resolve after the live event.
