Since 2022, the 100% remote events inherited from lockdowns have become the minority. The format that has taken hold is hybrid: a physical audience in the room, a remote audience following live, and interaction mechanics that work for both. On paper, it's the best of both worlds. In practice, it's a format that demands a specific technical design, where every shortcut shows.
In recent years, I've handled the technical side of dozens of hybrid events: B2B conferences (EBG Digital Benchmark in Berlin), multi-site product launches (Johnson & Johnson, 6 cities connected live), recurring corporate conferences (white-label for Morning, more than 300 filming sessions over 8 years), international tech customer evenings (Figma in Paris, Madrid and Barcelona). Audiences ranging from 80 to 1,500 people in person, plus the live broadcast. I've seen pretty much every possible configuration, and every possible mistake. This article gathers the 7 most common mistakes, and how I avoid them now.
In this article
Mistake #1: treating the remote audience as a secondary audience
It's by far the most common mistake. The organisation prepares its event as if it were a classic in-person event, then adds the live broadcast at the last minute as an option. Predictable result: speakers talk without wireless mics, slides are illegible on video, audience contributions aren't captured, and the remote audience drops off after 20 minutes.
Typical symptom
Remote completion rate below 30%
On a well-run remote production, the completion rate (percentage of viewers who watch to the end) hovers around 60-70%. Below 30%, that's the signal that the remote experience is low quality.
For the in-person audience, audio-visual quality doesn't have to be perfect: presence in the room, the atmosphere, coffee-break conversations all compensate. For the remote audience, those compensations don't exist. If the technique falls short, they leave.
The fix
Design the event with the remote audience first in mind. If the broadcast is good for them, it's necessarily good for the in-person audience too. The reverse isn't true. Concretely: individual wireless mics on every speaker (no shared lapel mics, no stand mics), 16:9 slides with minimum 24pt font sizes, dedicated camera on the audience for room contributions.
Mistake #2: using the venue's WiFi for broadcasting
I'm often told that "the venue's WiFi is very high-performance" and that we'll be able to use it. The WiFi of a hotel, a conference centre or a corporate headquarters is generally not sized to provide stable upload throughput for several hours. It's designed for classic web browsing for a large number of people.
On top of limited bandwidth, a venue's WiFi often goes through a corporate proxy, a firewall with specific traffic management, and is subject to fluctuations from other attendees' usage. These factors significantly increase the risk of dropout during your live.
Technical detail
For a stable 1080p broadcast, you need 15 Mbps of stable, dedicated, symmetric upload. For simultaneous multi-platform (YouTube, LinkedIn, X, TikTok, Instagram, private server), count 30-50 Mbps. These figures assume a connection reserved for the technical side.
The fix
Dedicated 5G router with multi-operator management. Network independent from the venue, isolated from public traffic, sized for your exact use. A necessary investment to secure a high-stakes event.
Mistake #3: underestimating hybrid interactivity
This is the aspect that fails most often. Interactivity works perfectly in 100% remote (everyone answers on their screen) or 100% in-person (everyone uses a clicker or terminal). But in hybrid, you have to reconcile two systems that don't talk to each other natively.
Typical example: in-person attendees vote or answer a poll via platform A. Remote attendees use platform B. Each platform calculates its results independently, then you have to add the two manually to display the consolidated result. That's exactly when errors happen.
Real-world case
Mismatch between the room and the live
Interactive poll during a convention. The on-screen display in the room announces results that don't match the figures mentioned in the remote platform's chat. That wobble damages the event's dynamic and creates a breakdown of trust for remote viewers.
The fix
Mandate a single platform that handles both channels. My Nomacast interactive tools (Chat, polls, quizzes, analytics & GDPR) handle hybrid interactivity natively with a unified interface and France-based hosting. Included in the service, to compare with the image cost when figures don't match between the room and the live feed.
Mistake #4: confusing webinar and live streaming
A Zoom or a Teams isn't live streaming. A webinar is an interactive meeting with a limited audience. A live stream is a one-way professional broadcast for a wide audience. Both have their place, but not for the same use.
Broadcasting an important event via a classic videoconference platform exposes you to several problems: video quality capped at 720p, audio compression that degrades speakers' voices, and no control over the final rendering (no branding, weak slide integration).
Webinar vs live streaming in practice
Webinar (Zoom, Teams): suited to an interactive meeting with 20-50 people where everyone can speak. Live streaming (vMix-type production gallery → YouTube, LinkedIn, X, TikTok, Instagram, private platform): suited to an event with 500+ people with TV-quality production and controlled contributions. Mixing the two is possible: streaming for the main feed and videoconferencing for the Q&A channel.
The fix
Use a video gallery (vMix or OBS) that handles the sources, produces the final mix with your branding, and broadcasts it to the platform of your choice. Videoconferencing can be kept as a parallel channel, run by a moderator who relays relevant questions to the host.
Mistake #5: forgetting moderation of remote questions
A successful hybrid event lets remote attendees contribute. The problem arises when this interaction isn't organised. The host receives too many questions at once and ends up ignoring them, which makes remote viewers feel left out.
The fix
Have a dedicated moderator who filters questions in real time, groups themes and prioritises the ones to be put to the host via discreet feedback. It's an essential role to guarantee the inclusion of online viewers.
Mistake #6: neglecting archiving and post-event use
A hybrid event produces a video file that has two potential lives. A legal life for some contexts (annual general meetings, board meetings, committees) where the file can be a probative document. A marketing life for others (conferences, launches, conventions) where the file feeds post-event communication, social media content, newsletters, replays. Most providers deliver an MP4 on a Google Drive link and that's it. It's insufficient in both cases.
What serious post-event archiving requires
Open and lasting format (MP4 H.264). Certified timestamping for legal documents. Retention period compliant with legal obligations. Marketing use: delivery of camera-by-camera rushes, vertical formats for social media, short dynamic clips.
The fix
Build archiving and content-recycling needs into the quote. Depending on your goal (legal or marketing), deliverables should include either an integrity certificate, or source files allowing careful editing afterwards.
Mistake #7: not planning a backup
A live event can't be redone later. Yet technical continuity plans are often neglected. An effective backup plan is a cascade of solutions where each level takes over if the previous one fails.
- Network redundancy: main connection complemented by an automatic backup on a different operator.
- Encoding redundancy: backup equipment ready to be activated instantly.
- Local recording: continuous physical backup even if the online broadcast stops.
- Human procedure: agreement with the organiser on what to do in case of a major incident to preserve the quality of the experience.
The fix
Define a factual backup plan validated upstream with the client. Test the activation of fallback solutions in real conditions during technical rehearsals.
What I take from dozens of recent hybrid events
"The difference between a hybrid setup that works and one that fails rarely comes down to equipment, it comes down to the upstream preparation."
Hybrid is not a degraded version of in-person. It's a format in its own right that demands specific technical design, clear upstream trade-offs, and execution without shortcuts. The savings made on the technical side show up on D-day.
Budget-wise, count between €3,500 and €12,000 (excl. VAT) for a well-run hybrid event depending on size and complexity. The difference with simple filming plays out across four areas: redundancy, hybrid interactivity management, remote moderation, and broadcast quality. Four areas that cost little in equipment, but a lot in skill and preparation time.
"A well-run hybrid event isn't visible. It's when something goes wrong that the technique gets noticed."
