Display Output

Output to your system's video outputs, including support for Display Link

ZoomISO v2 has a completely redesigned video engine that is built upon Zoom Raw Data access and accelerated by Apple Silicon. This powerful media system dramatically improves performance and significantly enhances the output image quality.

A variety of Output Modes allow the creation of video feeds based on a specific participant, active speaker, spotlight index, or screenshare. In addition, you can leverage several failover modes in case a participant disconnects from the call or turns off their video unexpectedly.

In addition to having the ability to embed isolated participant or mixed audio into NDI outputs, ZoomISO’s Advanced Audio system allows for fully customizing an audio export chain to any multichannel audio device on the system. 

With Advanced Audio, it’s easy to implement audio export chains such as isolating 32 channels of participant audio to Dante Virtual Soundcard or sending a variety of sub-mixes to Loopback for monitoring. Embedding ISO participant audio into NDI feeds for vMix is also easily achievable inside of the new Output Management interface.


More ZoomISO Features

ZoomISO is the only application that has access to a special, high bandwidth link to the Zoom Cloud, which allows for over 12 HD video feeds to be generated from a single instance of the app on supported hardware.

High Bandwidth Mode, particularly when enabling more than 6 1080p 30FPS outputs, requires updates to Zoom’s global infrastructure that are currently in progress, and may require until mid October or later to complete worldwide rollout.

Participant Management Interface

ZoomISO v2 introduces a new user interface optimized for efficiently managing large meetings and webinars. In the Participants View, you can search for a user by name, or you can apply a combination of filters to help you find exactly who you are looking for in an alphabetized list of all participants.

Easy to Use, but Incredibly Powerful

ZoomISO supports a variety of workflows, yet its core principles are simple to use. Once you have a configuration that works well for your studio, you can save the application state to a file that you can share, load, or merge into another project. In addition, ZoomISO offers many advanced controls of its media engine, allowing it to integrate into both simple and complex production ecosystems through both its user interface and industry-leading OSC API.

Integrations - The Power of OSC

Take advantage of OSC Routing for better management. ZoomISO’s OSC control over output routing and application settings allows you to better remotely manage your contribution system and switch participants on the fly. ZoomISO wraps around our popular ZoomOSC API, which powers integrations with third party interfaces including BitFocus Companion, Isadora, and Universe Control.

ZoomISO Lite and Pro Editions


After the Beta period, ZoomISO v2 will be available in two activation levels, Lite and Pro. ZoomISO Lite is designed to be an affordable solution for those producing small panels using contribution systems including NDI to vMix with embedded, isolated audio. ZoomISO Pro is for the high end, cutting edge broadcast production solutions, including using SDI for dense remote caller contribution with advanced workflows and controls.

Zoom High Bandwidth Mode**

*In conjunction with High Bandwidth Mode, ZoomISO Pro does not impose a software-level limit on video export quantity, though the number of video feeds the app can export will depend on the Mac hardware hosting the application. A Mac Mini M1 has been able to achieve 8 HD outputs. A Mac Studio has achieved 12 HD outputs. Please test in Trial Mode to determine if ZoomISO Pro meets your needs.

**Zoom High Bandwidth Mode increases the bandwidth allocation to the ZoomISO client from the Zoom Cloud, provided there is a sufficient internet connection. High Bandwidth Mode, particularly when enabling more than 6 1080p 30FPS outputs, requires updates to Zoom’s global infrastructure that are currently in progress, and may require until mid October or later to complete worldwide rollout. Any ZoomISO client updates required to fully enable this feature, if not already available, will be provided free of charge to ZoomISO Pro users. At this time, ZoomISO is the only product on the Zoom Platform that can leverage “High Bandwidth Mode,” so the infrastructure updates referenced above will not yet impact the decoders present in Zoom Rooms or Zoom integrations developed by third party companies. 

***In addition to bundling ZoomOSC Essentials as part of the ZoomISO Lite executable, the app also adds the ../list OSC Output, which enables integrations with third party systems including Universe, Isadora, and BitFocus Companion
