Getting started with ZoomISO

ZoomISO is a macOS application that lets you export individual Zoom meeting and webinar participants as isolated video and audio outputs. These outputs can be routed to a wide range of video formats, including Network Device Interface (NDI), Metal Syphon, Secure Reliable Transport (SRT), physical displays and DisplayLink, and Serial Digital Interface (SDI) through Blackmagic Desktop Video and AJA hardware products. ZoomISO also supports multi-channel audio inputs and outputs with tools like Dante Virtual Soundcard, Loopback, BlackHole, and more.

ZoomISO is useful for live production workflows where you need isolated feeds of remote participants. For example, routing individual Zoom participants into a vision mixer without relying on multiple "pinning machines." ZoomISO also includes an Open Sound Control (OSC) engine that allows remote control from hardware like a Stream Deck.
