ZoomISO - L.png


ZoomISO allows you to generate individual video outputs of the participants in a Zoom Meeting / Webinar, allowing you to easily recomposite them inside of a vision mixer, switcher, or media server. This macOS application supports a variety of output formats for popular production systems, and can export HD video in supported Zoom calls. 

With the release of ZoomISO into Open BETA, Liminal is thrilled to introduce the most highly-requested production feature on the Zoom platform, and we look forward to reviewing your feedback so that ZoomISO can fully revolutionize your decentralized production workflows.

Window Output

Assign participant feeds to displays for simple video output, either to a specific display or as a floating window.


HD Individual Outputs

ZoomISO can export participant video feeds at HD resolutions inside supported meetings*. 

  • 1-4 outputs at 1080/720p* 30FPS

  • 5+ outputs at 1080/720p* 15FPS**

  • Outputs at 180p or 360p 30FPS (Quantity determined by hardware abilities)

Additionally, ZoomISO can output individual feeds generated from automatic crops of the Zoom Gallery View. Select whether you want the outputs to be created by UserName, ZoomID, TargetID, or GalleryIndex.

Please note: encoding outputs requires significant system resources. Please explore the limits of your hardware, and provide feedback in our form below to help us verify expected performance and create a recommended hardware list.

*HD Meetings (720p and 1080p) require activation by Zoom Support for accounts which meet their requirements. Read more here

**We have found that Zoom limits the bandwidth sent to a client by reducing the framerate roughly by half after 4 HD Outputs

Leverage the Power of OSC

The new ../outputISO command provides fast and flexible routing abilities to assign Zoom participants to ISO outputs. Combined with a Stream Deck and Companion, the new OSC command opens a world of possibilities for video routing on the Zoom platform.
