In short
- Viewers online see the event a little later than the people in the room.
- The delay matters most for questions, polls, countdowns and shared cues.
- Brief the MC and speakers in plain words before the event.
- Test the delay at the venue instead of assuming a number.
Every livestream runs a little behind the room. Whether that matters depends on what your programme asks the online viewers to do, so decide that first and then brief your team.
Why the delay exists
The picture leaves the camera, is converted for the internet, travels to the platform, and then to each viewer’s device. Each step takes a moment. Viewers therefore see an action after the people in the room have already seen it.
The size of the delay depends on the platform, its settings and the connection. A test at your venue shows what you will really get.
Does it matter for your event?
For some programmes, a small delay is harmless. For others it causes confusion. Go through your run sheet and mark each item:
| Programme item | Does the delay matter? | Why |
|---|---|---|
| A speech or sermon, watched only | Usually not | Viewers just follow along |
| Live questions from online viewers | Yes | The speaker may have moved on |
| A poll or quiz with a time limit | Yes | Online voters have less time |
| A countdown or “everyone together” cue | Yes | Online viewers will be behind |
| A toast or prayer led from the stage | Sometimes | Online viewers join a moment late |
| Slides or screens in the hall | Depends on the source | See below |
Keep the table short and focused on your own event. The aim is to know which three or four moments need care.
Screens in the hall
Screens in the hall fed straight from the cameras follow the room closely. Screens that show the stream itself would be behind by the stream’s delay, and the mismatch is easy to notice. Say clearly which source feeds each screen. The guide on delivering camera video to venue screens explains the handoff.
How to brief the team
Use plain words. Here is an example of what you might say to the MC and speakers:
- “People online see us a few moments after the room does.”
- “When you take an online question, please repeat it, because the speaker may have moved on.”
- “For countdowns, count in the room first and tell online viewers to follow their own screen.”
- “Please do not refer to something that only people in the room can see unless you describe it.”
Share this with the MC, the speakers, the person who reads online questions and the AV operator. If the speakers join from elsewhere, also see rehearsing a livestream with remote speakers.
What to tell online viewers
Add one short line to the stream page, or have the MC say it at the start: “You may see things a few moments after the room.” This prevents messages about something that has already passed.
Test it before the day
At the venue, with the platform you chose, ask someone to clap or hold up a card and watch when it arrives on a second device. This gives you a real idea of the delay.
Do it with your own connection, since results change. The livestream planning checklist lists the other things to test. Remember that the sound for remote viewers and the sound in the room are separate checks; see livestream sound and in-room sound.
What we confirm for your event
- A delay test at the venue with your platform.
- Settings that shorten the delay for your programme.
- A named person who watches the stream during the event and tells the MC if something is off.
When you are ready, our event livestreaming service is available on request, confirmed for each event.
If your event has questions from online viewers, polls or in-room screens, tell us and we will plan a test of the delay with you. Send your date and venue and we will confirm what is possible.
