Blackmagic Design ATEM SDI Pro ISO (USB-C cable not included)

Blackmagic Design ATEM SDI Pro ISO

The ATEM SDI Pro ISO is a compact live production switcher that brings high-end broadcast connectivity to the portable "mini" form factor. By replacing HDMI ports with 3G-SDI, this model is designed for professional environments where long cable runs (up to 100 meters) and locking connectors are mandatory.

In 2026, it is the primary choice for professional field switchers, allowing for a "post-production ready" workflow where every camera feed is captured individually.

The "ISO" Advantage

The "ISO" designation is the most powerful feature of this unit. It allows you to:

• Record 5 Streams Simultaneously: It records all 4 individual SDI inputs (ISO) plus the final Program (PGM) feed as separate H.264 files to a single USB-C drive.

• DaVinci Resolve Project Export: It automatically creates a .drp project file. When you open this file in DaVinci Resolve, your live switch is already laid out on the timeline with all your cuts intact, allowing you to fine-tune the edit, swap shots, or regrade the footage.

• Audio ISOs: It also records each individual audio input as separate files, giving you total control over the sound mix in post-production.

Core Functionality

• 4 Standards-Converted SDI Inputs: Each input has its own converter. You can plug in a 1080p camera, a 1080i broadcast feed, and a 720p laptop, and the ATEM will instantly bring them all into the same project rate.

• Direct Streaming: Features a built-in hardware streaming engine. You can stream directly to YouTube, Twitch, or Facebook Live via the Ethernet port without needing a computer.

• USB Webcam Output: The USB-C port (cable not included) allows the switcher to be recognized by any computer as a "Blackmagic Design" webcam. This works perfectly for Zoom, Teams, or OBS.

• Built-in Multiview: The SDI output can be configured to show all 4 cameras, the preview, the program, and audio meters on a single monitor.

Technical Specifications

USB-C Cable Requirement (Not Included)

Since the USB-C cable is not included, you must ensure you purchase a high-quality USB 3.1 Gen 2 (10Gbps) cable if you intend to record all 5 ISO streams to an external SSD.

• Note: Using a cheap "charging" cable will often cause the recording to fail or drop frames because the data bandwidth for 5 simultaneous HD streams is significant.

Operational Insight (2026)

In 2026, the ATEM SDI Pro ISO is the "Swiss Army Knife" of remote production. Because it uses SDI, it eliminates the "HDMI handshake" issues common with cheaper switchers. It also features a Fairlight Audio Mixer internally, allowing you to apply compression, limiting, and 6-band EQ to every input to ensure professional sound.

Pro Tip: If you are recording to an SSD, use the Blackmagic Cloud integration. The ISO model can be set up to sync your proxy files or high-res files directly to the cloud while you are still shooting, allowing a remote editor to start working on the DaVinci Resolve project in real-time.
