The Blackmagic Design ATEM SDI Pro ISO is a professional 4-channel 3G-SDI live production switcher built for broadcast-quality multi-camera streaming and recording up to 1080p HD. Designed for demanding live events, it features an integrated control panel, Ethernet live streaming output, and a powerful hardware encoder — eliminating the need for any additional streaming software.
What sets the ATEM SDI Pro ISO apart in its category is its simultaneous ISO recording capability: it captures the switched program output and all four individual SDI input feeds to an external USB drive, while automatically generating a DaVinci Resolve project file — giving you a complete post-production-ready package straight from your live event.
Key features
- 4-Channel 3G-SDI Switching up to 1080p HD — handle up to four professional SDI camera feeds with broadcast-grade signal quality and instant cut, mix, dip, wipe, and DVE transitions.
- Full ISO Recording on All Inputs — simultaneously records the program output plus all four isolated SDI input feeds to a USB drive, so no moment is ever lost in post-production.
- Auto-Generated DaVinci Resolve Project — every session automatically creates a ready-to-edit DaVinci Resolve project file, with timecode-synced clips already mapped to a timeline.
- Advanced Keying & Effects — upstream and downstream keyers, advanced chroma keyer, dual linear/luma keyers, and a DVE transition processor for polished, broadcast-style productions.
- 2-Channel Digital Audio Mixer per Source — mix embedded SDI audio and analog audio inputs with per-source control, audio meters, and real-time monitoring via ATEM Software Control.
- Full BMPCC 6K/4K Camera Control & Tally — remotely control Blackmagic Pocket Cinema Cameras, sync timecode automatically across all cameras, and drive hardware tally lights from a single panel.

Frequently asked questions
Can the ATEM SDI Pro ISO record all camera feeds at the same time, or just the program output?
It records both simultaneously — the switched program stream and up to four individual ISO recordings of each 3G-SDI input are all captured at the same time to an external USB drive, along with embedded audio, analog audio, and graphics.
What file does the ATEM SDI Pro ISO create for post-production editing?
After your live production, the switcher automatically generates a DaVinci Resolve project file that maps all your ISO recordings and program output onto a timeline, so you can immediately open DaVinci Resolve and start refining your edit using the source footage already on your USB drive.
Does the ATEM SDI Pro ISO require a computer or external software to stream live?
No. It features a built-in hardware encoder and an Ethernet output, so it can stream live video up to 1080p HD directly to the internet without any additional streaming software. The ATEM Software Control Panel is used for configuration and monitoring but is not required to operate the stream once it is set up.
