Blackmagic Design ATEM SDI Extreme ISO – 8-Input Switcher

Product Overview

The Blackmagic Design ATEM SDI Extreme ISO is an eight-input 3G-SDI live production switcher for streaming, with built-in hardware streaming and nine-stream ISO recording. It captures all eight clean-feed inputs plus the program in real time and saves a DaVinci Resolve project, with four upstream and two downstream keyers, DVE, and a Fairlight mixer featuring per-input EQ and dynamics.

Product Description

ATEM SDI Extreme ISO provides eight standards-converted 3G-SDI inputs with re-sync and four SDI outputs, so it connects broadcast SDI cameras and recorders for ambitious portable productions. A built-in streaming engine streams over Ethernet (RTMP) to YouTube, Facebook, and Twitch, with streaming status and data-rate indication shown in the multi-view. Front-panel buttons handle recording, streaming, and output selection between program, direct camera feeds, and multi-view.

As an ISO model it records nine separate H.264 streams — all eight inputs plus program — with media-pool images, synced timecode, and camera-number metadata saved alongside, and exports a DaVinci Resolve project so all cuts, dissolves, and graphics open for re-editing. The switcher supports nine M/E layers, DVE picture-in-picture, chroma and luma keying, five pattern and two color generators, and a multi-input Fairlight mixer with compressor, limiter, and six-band parametric EQ per channel. USB acts as a webcam source for any video software at 1080 HD.

FAQ

How many cameras can it switch? Eight, each on a standards-converted 3G-SDI input with re-sync.

What does ISO recording capture? Nine separate H.264 streams — all eight inputs plus the program output.

Can I re-edit the show? Yes — it exports a DaVinci Resolve project with all cuts, dissolves, and graphics, aligned by timecode.

How does it differ from ATEM SDI Pro ISO? The Extreme ISO doubles the inputs to eight, records nine ISO streams, and adds more keyers and a fuller Fairlight mixer.
