Key Features of the Blackmagic ATEM SDI Pro ISO Mixer
- 4 x 3G-SDI inputs with sync and format/frame rate conversion on each channel for smooth multicam mixing in 10-bit 4:2:2 Rec.709.
- Built-in streaming via Ethernet or USB-C (RTMP) and ISO H.264 recording of all 4 inputs plus program, with DaVinci Resolve project saved.
- 10-window MultiView, DVE, advanced keyers, and generators for professional live graphics.
- Fairlight audio engine: compressor, gate, limiter, 6-band EQ, A-F-V, and precise gain control.
A Compact Mainstay in the ATEM SDI Range
Positioned at the heart of the ATEM SDI series, the Pro ISO retains the ergonomics of compact models while adding multi-track ISO recording and native streaming. It is the perfect bridge between small switchers and larger platforms, all while maintaining a professional SDI workflow.
Designed for Pro Live and Agile Post-Production
Ideal for corporate events, concert capture, worship, education, and creator streaming, this mixer targets teams demanding low latency, SDI reliability, and seamless workflow continuity through multicam editing in DaVinci Resolve.
Switching, Streaming, and Recording Without Compromise
Real-Time Video and Processing
All 4 x 3G-SDI inputs are resynchronized and equipped with format and frame rate converters. The 10-bit SDI program outputs ensure a clean signal, while the DVE and keyers handle overlays, transitions, and graphics with precision.
Integrated Streaming and ISO
Stream live over 10/100/1000 Ethernet or via USB-C for mobile sharing. Simultaneously record 4 clean feeds plus the program in H.264 with AAC audio, and automatically generate a DaVinci Resolve project for editing, audio remixing, and color grading.
Broadcast-Ready Fairlight Audio
The 6-input x 2-channel mixer offers per-channel A-F-V, compressor, gate, limiter, 6-band EQ, and peak control for broadcast-quality sound, with master gain management.
Control and Integration
Operate via the built-in panel, ATEM Software Control (Mac/Windows), or ATEM hardware panels. USB-C supports disk recording, webcam output, and updates, while Ethernet provides network control and streaming.
