Hybrid Event Formats
What formats can a hybrid event take?
A hybrid event format is the way an event combines an in-person audience with a remote one. The four common formats are simulcast, separate programs, remote hubs and in-person with a virtual add-on. They differ in how much the remote audience takes part and how much extra work they create.
This guide describes each format, compares them side by side and gives you questions to choose one. If you are new to the idea, read what a hybrid event is first. For the tools, see hybrid event technology.

The four formats
These names are common shorthand, not a standard. Planners combine them, so treat them as starting points.
Simulcast
One program, shown live to both audiences. The remote audience watches the same sessions as the room, often with chat or Q&A. It is the simplest format to plan, but remote attendees mostly watch rather than take part.
Separate programs
The in-person and virtual audiences get different sessions, built for their setting. Each program can suit its audience better, but you are in effect running two events.
Remote hubs
Small groups of people gather in local rooms and connect to the main event together. Hubs give remote attendees company, but each location needs a host and equipment.
In-person with a virtual add-on
The event is built for the room. Virtual attendees get a limited extra: a stream of the keynote, a recording or an online Q&A. It is the lowest effort and gives remote attendees the least.
The formats compared
Use the table to see the trade-off in each. The ratings are relative to each other, not measured, so adjust them to your own event.
| Format | Remote audience takes part | Planning effort | Staff needed | Best when |
|---|---|---|---|---|
| Simulcast | Watches, with chat or Q&A | Medium | A production crew and a moderator for remote questions | The content is a stage program and you want reach |
| Separate programs | Fully, in its own sessions | High | Two teams or two sets of hosts | Each audience needs something different |
| Remote hubs | In groups, with a local host | High | A host and equipment at each hub | People are spread across places and benefit from meeting locally |
| In-person with virtual add-on | Minimally | Low | A small streaming setup | The value is in the room and remote is a bonus |
How to choose a format
Start from your audience and goal, not from what looks impressive. Work through these questions in order.
What must the remote audience do?
If they only need to hear the content, a simulcast or add-on is enough. If they must network, discuss or exhibit, you need more than a stream.
Is the content the same for both?
A keynote travels well. A hands-on workshop often does not. Split the program where the content cannot be shared.
How many people can you staff?
Every extra format needs people: a moderator for remote questions, hosts for hubs, a producer for streams. Choose what your team can run well.
What can your technology do?
Check that registration, streaming and the app can serve both audiences, with sessions you can mark as online or onsite.
Hybrid event technologyWhat will you measure?
Decide how you will count and compare remote and in-person attendance before you pick, so the format can be judged afterwards.
Event KPIs
Mistakes that spoil any hybrid format
The format matters less than how well you treat the remote audience. These problems show up in all four.
Treating remote attendees as an afterthought
If the room gets the best seats, the best breaks and the best content, remote attendees notice and leave.
No one watching the remote channel
Assign one person to read remote chat and questions and pass them to the speaker.
Unclear times and places
Tell each registrant where and how to join their sessions, and send a separate reminder to each audience.
No test of the full setup
Run a rehearsal with both audiences connected, including audio from the room to remote viewers.
What Eventdex's pages say about hybrid events
Eventdex's hybrid event platform page describes live streaming of in-person sessions to virtual attendees, recordings for no-shows to rewatch, sessions divided by whether registrants are online or onsite, and networking features such as chat, breakout rooms and digital booths. Eventdex's pages do not name the four formats above or describe remote hubs.

FAQ
Hybrid Event Formats: common questions
What are the main hybrid event formats?
Four are common: simulcast, separate programs, remote hubs and in-person with a virtual add-on. They differ in how fully the remote audience takes part and how much work the organizer carries.
Which hybrid format is easiest to run?
In-person with a virtual add-on, because the event is built for the room and remote attendees get a limited extra. It also gives remote attendees the least.
Which hybrid format is best for engagement?
Formats where remote attendees have their own ways to take part, such as separate programs or remote hubs, usually engage them more than a stream alone. They also take more planning.
Can I mix formats?
Yes. Many events stream the keynote as a simulcast and run workshops as separate programs. Choose by session, not for the whole event.
Does Eventdex support these formats?
Eventdex's hybrid event platform page describes live streaming, separate online and onsite sessions and networking for both audiences. Eventdex's pages do not describe remote hubs. Ask in a demo how your chosen format would run.
