Blackmagic Design’s ATEM SDI Pro ISO is a compact powerhouse for modern Four 3G-SDI inputs are joined by two 3G-SDI outputs as well as 2 possible paths the web for streaming – USB Webcam out or direct stand-alone streaming by RTMP. Recording is available for the program cut as well as each input by USB-C (choose one between Webcam out or Recording).

Each of the inputs has built in sync and conversion for any SD/HD/3G-SDI signal rate to match the switcher’s current settings. If Blackmagic Design Cameras are coming in, camera control is and embedded within each output. Embedded audio may be used from each input and two 1/8” line/mic inputs with plug-in power are also provided with level and mute controls on the panel for each, and a robust set of DSP and EQ are available in software including Compressor, Limiter, Expander.

Two SDI Outputs allow easy use in the room with Program and Multiview outputs – Output 1 has direct control buttons to swap between Multiview, Program, or any input direct feed. Chroma, Luma, and DVE are available for use the Upstream and Downstream key.

When you need to add a streaming element, the ATEM SDI Pro ISO provides the program output in 2 ways. First, you can simply grab the USB-C Output and connect it to any computer with your choice of video conferencing software – the unit appears as a webcam without any driver installation and sends a high-quality webcam feed up to 1080p60. Alternately, you can choose to set the unit up to stream directly out to any common CDN or streaming platform that accepts RTMP feeds with H.264 encoded video (that’s pretty much all of them). Once this is set up, the ATEM will stream out using the “ON AIR” button, without requiring a computer.

Finally, recording. The ATEM SDI Pro ISO can use the same H.264 streaming encoder to simultaneously record up to all 4 input feeds plus the switched program output to an attached USB-C disk. A Davinci Resolve project file is captured as well – if this recorded project is loaded into Davinci Resolve for editing, the live cut decisions are loaded into the timeline and small adjustments or shot substitutions from the live cut are easy to perform.
