ZoomISO - L_2.png

ZoomISO generates 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, We are thrilled to introduce the most highly-requested production feature on the Zoom platform.

ZoomISO 1.1.1

Output Formats



NewTek NDI


Send IP-based Video across an ethernet network with wide application compatibility. Expect output bandwidth to be about 50Mbps for 1080p outputs

 ZoomISO now supports NDI

Blackmagic DeckLink*

Export participants to individual SDI outputs using BlackMagic hardware on your Mac

*With Syphon - DeckLink or NDI® - Decklink Conversion Software
See below for links

Window + Fullscreen Output

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

ZoomISO Features

Select 5 participants to output full HD isolated video at the maximum quality that Zoom can receive (HD video in Zoom requires per account activation by Zoom Support). Additional HD outputs will lower the framerate on incoming feeds. Full details below.

Up to 5 Participant Outputs at 720/1080p HD

Unlimited 360p Outputs

Pull as many 360p participant feeds as your hardware can encode. Perfect for audience contribution, video walls, or custom gallery layouts.

Gallery Crop Outputs

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.

Low-Profile Presence in Meetings

To generate outputs, simply join a Zoom meeting with the ZoomISO client application, which will appear as a regular participant that can be renamed.

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.

Additional Output Information:

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

  • 1-5 outputs at 1080/720p* 30FPS

  • 6+ outputs at 1080/720p* 15FPS**

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

*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 5 HD Outputs

Please note: encoding outputs requires significant system resources. Please test for performance on your hardware before production use.

Why ZoomISO instead of Other Solutions?

Reduce the number of machines in your system.

Each ZoomISO instance can generate 5x 1080p participant feeds. Previous contribution methods require multiple dedicated computers pinning 1-2 participants at a time. Save costs, ensure scalability, and control from a central OSC interface with ZoomISO.

OSC Routing for better management.

OSC control over output routing and application settings allows you to better remotely manage your contribution system and switch participants on the fly. 

With Syphon, NDI, and direct monitor output support, ZoomISO offers flexible options for sending video. Direct DeckLink outputs, additional formats, more settings and advanced options are in development.

Professional Options.

We have your back.

ZoomISO is an actively developed utility with support provided to paying customers. We want to ensure that our application fits your production needs and is properly compatible with your hardware.
