The Blackmagic Design ATEM SDI Extreme ISO Switcher is a professional 8-channel live production switcher built for broadcast-grade live streaming and ISO recording. With eight 3G-SDI inputs accepting signals up to 1080p60, per-input frame rate and format converters, and seamless RTMP streaming via Ethernet or USB-C to platforms like YouTube, Facebook Live, and Twitch, it delivers uncompromising flexibility for live events, studio productions, and on-location broadcasts.
What sets the ATEM SDI Extreme ISO apart is its ability to simultaneously record all eight individual input feeds plus the program output as MP4 files, automatically generating a DaVinci Resolve project file for effortless post-production. Combined with a powerful 11-input audio mixer, up to 16-view HD multiview monitoring, four upstream and two downstream keyers, and 4G/5G mobile data support as a streaming backup, this switcher is a complete live production hub in a single unit.

Frequently asked questions
What does ‘ISO’ mean on the ATEM SDI Extreme ISO, and how does the recording work?
The ‘ISO’ designation means the switcher can independently record all eight 3G-SDI input feeds as separate MP4 files, in addition to the final program output, via the USB-C ports. It also automatically generates a DaVinci Resolve project file so you can re-edit, color grade, or correct mistakes after the live event.
Which live streaming platforms does the ATEM SDI Extreme ISO support?
The switcher streams via RTMP over Ethernet to YouTube, Facebook Live, Twitch, Zoom, Microsoft Teams, Skype, and any other RTMP-compatible platform. You can also output via USB-C so your computer recognizes it as a webcam for use in virtually any video software.
Can I use cameras with different frame rates and formats on the same switcher simultaneously?
Yes. Every 3G-SDI input has its own discrete frame rate and format converter with re-sync, so you can mix signals from professional broadcast cameras, URSA Mini or Blackmagic Studio cameras, consumer cameras, game consoles, and computers — all at the same time — without any compatibility issues.
