Running an event online or hybrid

A conference talk delivered to a camera works about as well online as it does in a room, because the format was already one person talking while everyone else listened. A session that depends on people bumping into each other between sessions, sometimes called the corridor track, does not survive the move to a screen at all, because there is no corridor. Before deciding what goes online and what stays in person, it helps to look at each session type on its own terms.

Talks and keynotes

A single speaker addressing an audience translates to a screen with the least loss, because the audience was already sitting still and listening. The adjustments that matter are production ones: a camera close enough to show the speaker's face, audio taken from a lapel or headset mic, and slides shared as a clean feed. Timing also gets tighter online, because a remote attendee has a closed tab within reach the moment attention drifts, so a 45-minute in-person keynote is worth trimming for the online audience.

Panels and moderated Q&A

Panels hold up online provided the moderator manages a chat queue with the same discipline as a roving microphone, taking questions in order. The format that fails quietly is the mixed panel: some speakers in the room, one joining remotely on a screen at the side. The remote panellist gets talked over, loses the visual cues the in-room speakers are giving each other, and ends up contributing less. If a panel includes a remote speaker, the moderator needs to actively bring them into the conversation. Guidance on briefing panellists for this is covered in Finding, Choosing and Looking After Speakers.

Workshops and hands-on sessions

Workshops degrade further online, because the format depends on a facilitator reading the room and adjusting, and that signal is much weaker through a grid of video tiles. Breakout rooms exist in most conferencing platforms, but a facilitator running four breakout rooms remotely cannot walk between tables the way they would in a hotel function room, and engagement drops as attendees keep a second tab open. The sessions that survive are the ones with a single, explicit task and a fixed check-in point, run with a smaller group than the in-person version would take. A workshop built around loose, evolving discussion is usually better cut from the online programme than run badly within it.

The corridor track and informal networking

This is where online events lose the most and where organisers most often assume a fix exists that does not. The value of an in-person conference is not only the sessions; it is the conversation in the queue for coffee, the person you sit next to by chance, the follow-up chat after a talk that never happens on a schedule. None of that survives a video call, because a video call has no incidental space in it, only the meeting you scheduled. A hybrid event that gives remote attendees the sessions but nothing built specifically for them to meet each other is giving them a smaller version of the in-person ticket. A structured mechanic, such as timed small-group video calls matched by topic or role, replaces some of this, but it has to be designed and staffed.

Exhibition and sponsorship

Sponsor stands depend on foot traffic and the chance conversation that comes with it, and that does not transfer to a banner in a virtual lobby or a sponsored slide before a session. A sponsor who has paid for a stand at an in-person event and is offered a logo online is being offered something with a different value, and pricing that tier as if it were equivalent tends to show up later as a renewal problem. How this affects the sponsorship line in the budget is part of the wider pricing decision covered in Ticket Pricing and Making the Numbers Work.

Once you know which sessions belong online and which do not, the next decision is how the programme itself needs to change in length, pacing and format to carry both audiences without either one being an afterthought, covered in Designing a Conference Programme.

A hybrid event runs two events at the same time: the room and the stream. Each needs its own equipment, its own staffing and its own line in the budget, and the plan that treats the stream as something the venue's AV supplier can bolt on for a bit extra is the plan that fails on the day. Remote attendees notice the difference between a webinar bolted onto a conference and a conference actually built for two audiences within the first ten minutes.

Equipment: more than a camera on a tripod

A single wide-angle camera pointed at a lectern produces a stream nobody watches past the first session. A workable hybrid setup needs at least one camera on the speaker and one on the room, a vision switcher to cut between them, dedicated sound feeding the stream separately from the room PA, and an internet connection that does not share bandwidth with delegate wifi. Venue-supplied AV is usually built for the room. Ask specifically whether the quoted rig includes a dedicated encoder and a second internet line.

Staffing: a job, not a task bolted onto someone else's

Running the stream needs a person whose only responsibility is the stream: watching for dropped feeds, cutting between cameras, and keeping the recording running. Someone else needs to own the remote audience specifically, reading the chat or question queue and getting those questions into the room, because a speaker fielding room questions will not also be checking a laptop for remote ones. Treating either of these as something the session chair or the AV technician can do alongside their existing job is where hybrid events quietly go wrong.

Platform: a separate contract from the venue's AV

The platform, meaning the software that carries the stream and handles remote interaction, is a different purchase from the venue's AV contract and needs choosing on its own terms. A platform built for one-way webinars will not handle breakout discussion, live polling or a remote question queue with any grace, so test the platform with the actual session formats planned for the programme before booking it.

Production: captioning and recording are a budget line

Live captioning (CART), meaning a human or automated transcript displayed in real time, has a cost that scales with the number of hours and the accuracy required, and it is worth costing early. The Equality Act 2010 places a duty on organisers to make reasonable adjustments, and for a hybrid event that duty extends to the remote experience as well as the room, so this is a decision to make when the production budget is drawn up. Recording and editing the session for later viewing is a further cost on top, and one that is easy to forget because it happens after the event is technically over.

Why "we'll just stream it" is not a plan

The phrase describes an intention. A genuine hybrid production needs equipment, staffing, a platform and post-production accounted for separately, on top of everything the in-person event already costs, and an organiser who has not costed all four before setting the ticket price will find the gap appearing as a shortfall after the event. For a worked breakdown of where these costs typically sit against an in-person budget, see Worked Examples and Templates, and for the wider venue and catering costs a hybrid event still carries on the room side, see Venues, Catering and the Costs Nobody Budgets For.

A webinar platform is built to send one speaker's voice and slides to a large, mostly silent audience. A conference platform has to do that and also handle parallel sessions, breakout conversations, a speaker green room, live captioning, and a way to moderate chat across all of it at once. Choosing the first when you need the second is the single most common platform mistake organisers make, and it usually only becomes visible on the day, when the schedule needs two things happening at the same time and the software will only do one.

Ask these questions before you sign anything

Most platform vendors will answer these clearly if you ask directly, and a vendor who cannot is telling you something.

• How many concurrent tracks can run at once, and is that a plan limit or a technical limit?
• Does breakout room capacity scale with total attendee numbers, or is it capped regardless of size?
• What happens to registration and ticketing data: does the platform integrate with what you are already using, or does it need a separate sign-up?
• Who provides live technical support during the event itself, and is that included or a paid add-on?
• Does the platform support live captioning (CART), and can it feed a third-party captioner if the built-in option is not accurate enough for your audience?
• What moderation tools exist for chat and Q&A, and can a moderator remove a message or a person without ending the whole session? This is where your code of conduct becomes enforceable.
• What happens to the recording afterwards: who owns it, and what are the on-demand viewing terms for attendees who could not make the live slot?

What to test, not just ask about

A sales demo shows you the platform working well with five people in the room. A conference needs to know how it behaves with your actual numbers, on the connections your attendees actually have. Run a full technical rehearsal with the speakers who will use it live. Load-test with a number close to your expected peak concurrent attendance. Check what happens if the platform drops mid-session: is there a fallback stream, and does anyone on your team know how to trigger it without a support call first.

The single-track trap

A platform that handles one stream beautifully can still be the wrong choice for a hybrid event (one running in person and online at the same time) with two or three parallel sessions, because the limitation only shows up once you try to schedule two things at once. If your programme has parallel tracks, confirm concurrent-session capacity before you commit. The worked examples and templates page includes a sample run-of-show that shows where these constraints tend to surface first.

A programme built for a room does not survive a straight transfer to a screen. The mechanisms that hold a live audience, a shared space, the mild social pressure of sitting in a row, the option to lean over and whisper a reaction, simply are not there for someone watching from a laptop. Session length, format and the way interaction is built into the day all need rethinking.

Session length has to come down for a remote audience

A 60-minute panel that holds a room comfortably starts losing a remote audience after about 20 minutes, because there is nothing stopping them opening a second tab. The fix is not simply a shorter version of the same session; it is a different rhythm, with 25 to 30 minute blocks and a clear break or format change between them. A single long format run without a break online reads as disengagement built into the schedule.

Some formats travel online better than others

A keynote translates reasonably well, because it is already a one-directional format built around a single speaker and a screen. A loosely structured panel discussion is the hardest to sustain: the visual cues that make live back-and-forth work, glances, timing, body language, mostly disappear on a video call, and what is left is people talking over a lag. Structured formats hold up better online: a facilitated Q&A with questions submitted in advance, or short individual talks followed by a tightly moderated discussion segment, both give the session a shape that does not depend on room energy to work. See Designing a Conference Programme for how session format choices play out for an in-person audience, and adjust from there.

Interaction has to be designed in, because it will not happen by accident

In a physical venue, most of the real interaction happens outside the sessions: in the queue for coffee, in the informal conversation space some organisers call the corridor track. None of that exists for a remote attendee unless the programme creates it deliberately, through scheduled breakout rooms with a specific task, structured polls tied to the session content, or a moderated question queue that feeds into the stage. A remote attendee left with only a passive stream and an unmonitored chat is, in practice, watching television.

The adjustments that stop remote attendees becoming an afterthought

For a hybrid session, the room audience gets eye contact, asides and the informal networking around it; the remote audience gets none of that unless someone builds it in. That means a named person monitoring the remote chat and feeding questions to the stage, speakers briefed to address the camera and not only the room (see Finding, Choosing and Looking After Speakers for what a speaker briefing needs to cover), and schedule buffers built in for live captioning (CART, communication access realtime translation), which needs a few seconds of lag the timing has to allow for rather than fight. A code of conduct written only for physical spaces misses the chat window and the breakout room, both of which need the same coverage as the main hall; see Accessibility and Codes of Conduct for what that coverage needs to include.
