A six-participant gallery composed in OBS from individual CoreVideo sources, each guest in their own rounded, bordered tile on a branded background

Free, open-source OBS Studio plugin

Bring Zoom participants into OBS as native sources.

CoreVideo joins the meeting through the Zoom Meeting SDK and hands OBS each participant's own video and audio as a real source — no NDI, no virtual camera, no screen capture, and no second machine. Follow the active speaker, pin spotlight slots, take the screen share, and record every guest to an isolated file.

One source per participantEach Zoom participant becomes a separate OBS source at up to 1080p, with their audio on its own track — not a crop out of a gallery screenshot.

CoreVideo TilesArrange participant feeds in a styled gallery within one OBS source, with rounded corners, borders, and flexible layouts.

Active speaker & spotlightPoint a source at whoever is talking, at Zoom spotlight slot 1…N, or at a fixed guest with an automatic failover if they drop.

Screen share & interpretationSubscribe to the live screen share, and pull existing Zoom interpretation audio channels in as dedicated sources.

ISO recordingRecord every assigned participant to an MP4 video file and a matching PCM WAV audio file, alongside the main program recording.

Active Speaker DirectorAn automatic take with a hold time, a sensitivity threshold, an exclusion list, and a “require video” rule — so the cut follows the conversation without chattering.

Output profilesThe Output Manager saves and reloads a whole assignment set, so last week’s routing comes back on the next show instead of being rebuilt by hand.

Stream Deck & CompanionA Bitfocus Companion module (v5 or newer) picks the output and the participant by name from the live roster, so a button keeps working after somebody rejoins.

Remote controlA TCP and OSC control surface drives joins, assignments, and recording from whatever already runs your show.

OBS Studio multiview: preview and program above four scenes built from individual Zoom participant sources - the host alone, the host with a reader, the host with the active speaker, and the active speaker full frame — Every guest arrives as their own OBS source, so scenes, transitions, and the multiview all work the way they already do — this is stock OBS, cutting between Zoom participants.

Talkback, without leaving the meeting

Every show that runs on Zoom eventually needs a way to speak to one person without speaking to the room. The Zoom Meeting SDK carries a private talkback path alongside the meeting floor — 16 channels, up to 10 people each, and members duck under your voice rather than being muted — and both products here are built on it.

ZComms is the standalone answer: a full intercom desk with named talk keys, ALL CALL, latch, extern feeds from a multichannel interface, and breakout-aware routing. It ships today. The OBS plugin also has a Zoom Talkback dock in the Windows v0.1.45-beta.1 build. It is absent from the recommended Windows v0.1.44 release and unavailable on macOS.
