Blackmagic ATEM SDI Extreme ISO – Professional 8-Channel SDI Live Production Switcher

The Blackmagic ATEM SDI Extreme ISO is a professional live production switcher designed for broadcasters, churches, event production companies, studios, corporate presentations, sports productions, educators, and content creators who need reliable multi-camera switching and recording in a compact system. Featuring 8 standards-converted 3G-SDI inputs, built-in live streaming, multiview, USB webcam output, DVE effects, chroma keying, media playback, and ISO recording, the ATEM SDI Extreme ISO provides a complete workflow for professional HD live production.

With its combination of hardware switching, live streaming and isolated recording, this Blackmagic Design switcher makes it possible to manage complex productions while retaining individual camera feeds for editing later. The system can record nine separate H.264 video streams in real time—eight clean SDI inputs plus the program output—and automatically saves a DaVinci Resolve project file containing the live switching information.

Professional 8-Input SDI Switching

The ATEM SDI Extreme ISO provides eight 3G-SDI inputs, giving production teams the flexibility to connect multiple professional cameras, SDI converters and other compatible video sources. Every SDI input includes built-in re-sync and frame-rate/format conversion, helping simplify multi-camera production when sources are not perfectly matched.

The switcher supports a wide range of HD formats, including 720p and 1080p standards as well as 1080i formats. This makes it suitable for live events, broadcast-style productions, conferences, houses of worship, sports coverage, interviews and studio productions.

ISO Recording for Complete Production Control

One of the major advantages of the ATEM SDI Extreme ISO is its isolated recording capability. The system can simultaneously record the eight individual SDI camera inputs as separate H.264 files while also recording the program output.

This gives editors access to the original camera angles after the live event. Instead of relying only on the final switched program, production teams can return to individual camera recordings and create alternative edits, highlight videos, social media clips and promotional content.

The live switching information is also saved as a DaVinci Resolve project file, helping editors reconstruct and refine the production after recording.

DaVinci Resolve Editing Workflow

The ATEM SDI Extreme ISO is particularly useful for production teams using DaVinci Resolve. During an ISO recording, the switcher creates a project file containing the switching information and records the individual camera sources.

This provides a practical bridge between live production and post-production. Editors can refine transitions, replace shots, adjust the sequence and produce additional versions of the program without having to recreate the entire live production from scratch.

For broadcasters and content creators producing regular events, this workflow can significantly simplify the process of turning a live production into finished video content.

Built-In Live Streaming

The ATEM SDI Extreme ISO includes a hardware streaming engine for direct live streaming. It supports streaming through Ethernet and can also use a shared mobile internet connection through USB-C.

This makes it suitable for organizations that want to stream directly from their production setup without requiring a separate computer-based software encoder. Depending on the production environment, it can be used for live broadcasts, online conferences, church services, interviews, product launches, webinars and other multi-camera events.

Professional Audio Mixing

Audio production is also integrated into the ATEM SDI Extreme ISO. The switcher features an 11-input, 2-channel audio mixer with individual channel control, audio-follow-video functionality, level and peak metering, and Fairlight audio processing.

Its audio tools include a compressor, gate, limiter and six-band parametric equalizer. Two 3.5mm stereo audio inputs are available for connecting external analog audio sources such as microphones or mixers.

This integrated audio workflow allows operators to manage video and sound from the same production system.

Advanced Broadcast Effects

The ATEM SDI Extreme ISO includes a range of production tools for creating polished live programs. Its built-in DVE can be used for transitions and picture-in-picture effects, while chroma keyers support green-screen production.

The switcher provides four upstream keyers, two downstream keyers, up to four advanced chroma keyers and up to four linear/luma keyers, giving production teams considerable flexibility for graphics, overlays, presenters and visual effects.

USB-C Recording and Webcam Output

The integrated USB-C connections provide additional workflow options. The ATEM SDI Extreme ISO can record video directly to external USB-C storage, making it practical for productions where direct recording is required.

USB-C can also provide webcam output, allowing the switcher to function as a professional video source for compatible computer applications. This is useful for online meetings, streaming platforms, remote presentations and content creation workflows.

Ethernet Connectivity and Software Control

The switcher includes 10/100/1000 Base-T Ethernet, which supports live streaming, software control, software updates and connection to compatible control panels.

Blackmagic Design provides ATEM Software Control for Mac and Windows, giving operators access to switching, audio, media and other production controls from a computer.
