Blackmagic Design - Switcher ATEM SDI Extreme ISO

The Blackmagic Design ATEM SDI Extreme ISO is the ultimate portable live production switcher for professional broadcasters, event producers, and content creators who demand uncompromising quality and flexibility. This advanced video switcher builds upon the capabilities of the ATEM SDI Pro ISO model by offering 8 SDI inputs and 4 SDI outputs, making it the ideal solution for multi-camera productions that require simultaneous recording of every camera angle. With the ability to record 9 separate H.264 video streams in real time—including all 8 clean feed inputs plus the program output—the ATEM SDI Extreme ISO transforms live production workflows by enabling full post-production flexibility with DaVinci Resolve project file integration.

Key Features
8 x 3G-SDI Inputs with Re-Sync and Format Conversion

The ATEM SDI Extreme ISO features eight 3G-SDI inputs that support 10-bit HD video with 2 channels of embedded audio. Each input includes built-in re-sync and frame rate and format converters, ensuring seamless integration of cameras and sources with different resolutions and frame rates. This eliminates the need for external converters and simplifies multi-camera setups.

Simultaneous 9-Stream ISO Recording

One of the most powerful capabilities of the ATEM SDI Extreme ISO is its ability to record 9 separate H.264 video streams in real time. The switcher records:

8 x SDI ISO inputs as H.264 .mp4 files at up to 70Mb/s quality with AAC audio

1 x Program output as H.264 .mp4 file at streaming quality settings

10 x 2-channel audio inputs recorded as separate 24-bit 48KHz .wav files

The program switching is also recorded as a DaVinci Resolve project (.drp) file, allowing you to open your live production in DaVinci Resolve for editing, audio remixing, and color correction.

4 x SDI Program Outputs

With four SDI program outputs, the ATEM SDI Extreme ISO provides exceptional routing flexibility for multi-destination workflows, including confidence monitoring, talent returns, and multi-venue distribution.

Professional Audio Mixing with Fairlight Enhancements

The built-in 11-input x 2-channel audio mixer delivers broadcast-quality audio processing. Each channel features selectable On/Off/Audio-Follow-Video modes, separate gain control, and level and peak metering. The integration of Fairlight audio enhancements—including compressor, gate, limiter, and 6 bands of parametric EQ—provides professional-grade audio shaping capabilities.

Advanced Keying and Effects

The ATEM SDI Extreme ISO offers extensive visual effects capabilities:

4 Upstream Keyers for advanced compositing

2 Downstream Keyers for titles and graphics overlay

Up to 4 Advanced Chroma Keyers for green screen production

Up to 4 Linear/Luma Keyers

2 DVE channels with borders and drop shadows

5 Pattern Generators and 2 Color Generators

Multi View Monitoring

The configurable Multi View monitoring supports 16, 13, 10, 7, or 4 up views, displaying Program, Preview, all 8 SDI inputs, SuperSource, Media Player, Streaming Status, Recording Status, and Audio Meters. This comprehensive monitoring solution provides complete situational awareness during live productions.

Direct Live Streaming

Built-in streaming capabilities allow direct live streaming using Real Time Messaging Protocol (RTMP) over Ethernet or a shared mobile internet connection over USB-C. This enables one-touch streaming to platforms like YouTube, Facebook, and Twitch without the need for additional streaming hardware.

Flexible Control Options

The ATEM SDI Extreme ISO includes a built-in control panel and is compatible with optional hardware panels including ATEM Micro Panel, ATEM 1 M/E Advanced Panels, ATEM 2 M/E Advanced Panels, and ATEM 4 M/E Advanced Panels. The included ATEM Software Control Panel for Mac and Windows provides comprehensive software-based control. Ethernet (10/100/1000 BaseT) and USB-C connections are supported for control, streaming, and software updates.

External Media Recording

The USB-C 3.1 Gen 1 expansion port enables direct recording to external media such as SSDs and flash drives. The system supports media formatted as ExFAT (Windows/Mac) or HFS+ (Mac) file systems.

Use Cases
Multi-Camera Live Events

The 8 SDI inputs make the ATEM SDI Extreme ISO ideal for concerts, conferences, sports events, and corporate productions where multiple camera angles need to be switched and recorded simultaneously.

Broadcast and Studio Production

With professional features like 10-bit color precision, 4:2:2 sampling, and Rec 709 color space, this switcher meets the demands of broadcast-quality production.

Streaming and Content Creation

Built-in RTMP streaming enables direct broadcasting to major platforms, while ISO recording provides素材 for post-production editing and multi-cam content creation.

Post-Production Workflows

The DaVinci Resolve project file recording allows editors to open the live production session directly in DaVinci Resolve, complete with all switcher cuts, audio adjustments, and effects.
