Five speakers in Zoom are five separate signals in the switcher, each with isolated audio. The director works with them like studio cameras, not with a gallery layout.
ZoomISO is a Liminal app for macOS that connects to a Zoom meeting and outputs the video and audio of every participant in isolation, as separate outputs for a broadcast system. Instead of one captured window with a gallery the director gets a source per person and builds the picture themselves: in vMix, OBS, on an ATEM switcher or in any system that accepts NDI, SDI or SRT.
Outputs are software and hardware. Software: NDI, Metal Syphon and SRT. Hardware: Blackmagic cards over SDI and SMPTE 2110, display output with DisplayLink emulation, AJA cards over SDI and HDMI. Audio goes out per channel to any multichannel device: Dante Virtual Soundcard, Loopback, BlackHole, the embedded audio of the cards, or is embedded in each participant's NDI and SRT stream.
One Mac delivers about 16 feeds at 1080p and 30 frames per second. The Lite edition is limited to four outputs, Pro is limited only by hardware. Part of the Enhanced Media add-on together with ZoomOSC, which controls what ZoomISO outputs.
Screen capture gives one picture with someone else's layout and mixed audio. Isolated feeds give the director freedom.
Every participant is a separate video output. The director puts the speaker full screen and the moderator in the corner without asking Zoom.
Each participant's audio on its own Dante channel or NDI track. The sound engineer mixes, compresses and sends it to the hall, as from microphones.
NDI for IP production, SDI for a classic control room, SRT for transport over the internet. Nothing to rebuild.
Outputs, audio, capacity, editions
Each participant's video and audio separate from the rest. Zoom's gallery and layout do not affect the outputs.
Software outputs: NDI for the network, Metal Syphon for apps on the same Mac, SRT for transport over the internet to another control room.
Blackmagic Desktop Video cards over SDI and SMPTE 2110, display output with DisplayLink, AJA cards over SDI and HDMI. A classic control room without rebuilding.
The audio export chain is configured to any multichannel device: Dante Virtual Soundcard, Loopback, BlackHole, the embedded audio of the cards.
A participant's audio is embedded in their NDI or SRT stream. One source in the switcher carries both picture and voice.
About 16 feeds at 1080p and 30 frames per second from one instance. More participants means a second Mac.
Lite up to 4 outputs, Pro with no limit on the number of outputs, the hardware sets the ceiling. Chosen by the size of the event.
ZoomOSC controls who is spotlighted and who is on air, ZoomISO outputs. Together they turn Zoom into a controllable source.
A Mac, the app from version 3.0.0, an Enhanced Media add-on licence per user. Hardware outputs over SMPTE 2110 and through AJA cards are in beta. Paid.
Wherever Zoom sits in the control room
A guest over Zoom goes out over SDI with isolated audio. For the switcher and the sound engineer they are no different from a studio camera.
Remote speakers on the hall screens as separate sources. The director switches them, audio goes to the hall on its own channels.
Executives from different cities in one picture assembled by the director, not by Zoom's layout.
Each teacher as a separate window in vMix or OBS, the presentation as a separate layer.
A stream over SRT goes through the internet to a partner's studio or a streaming venue.
Choosing the Mac and cards for the number of participants, configuring outputs and the audio chain with the customer's engineer, pairing with ZoomOSC, a test broadcast. Then support in Russian.
Remote guests on air look like studio cameras.
The room and remote speakers are mixed into a single picture.
The instructor and the material are separate sources.
We'll give you a remote demo Monday to Friday, 10:00–16:00 Moscow time, answer all your questions and provide trial access so you can explore the system yourself.
