The 30-Minute Technical Rehearsal That Can Save a Live Stream

Most livestream failures are not mysterious. They are small problems that were sitting there waiting to be discovered.

The wrong microphone is selected. A video has no embedded audio. A remote speaker has joined from a laptop with an aggressive corporate firewall. The presentation is 16:10 rather than 16:9. Nobody knows who is taking the stream off the holding slide.

A short, disciplined rehearsal catches a surprising number of them.

Start at the audience end

Before looking at the production equipment, open the event exactly as an attendee would.

Use a normal laptop or phone, ideally on a connection outside the production network. Check the joining link, authentication, player, audio level, captions and chat or Q&A functions.

This is important because a perfect signal leaving the encoder does not guarantee a perfect experience at the other end.

Run the opening sequence

Don't just test individual components. Rehearse the first few minutes in order.

Holding slide. Countdown if there is one. Opening sting. Presenter microphone. Slides. First video. Remote contributor.

The transitions between things are often where mistakes appear.

If somebody is responsible for pressing a button, saying a cue or muting a source, that action should happen in rehearsal. A technical check that consists of everyone saying "mine works" is not the same thing.

Check every source that makes sound

Audio causes more trouble than almost anything else.

Listen to every microphone, video playback machine, remote caller and presentation source. Check that stereo material is behaving properly and that remote contributors are not hearing themselves back with a delay.

Ask remote speakers to use headphones where practical. Confirm which microphone and camera their computer is actually using. If their connection is marginal, decide before the session whether audio-only would be safer than gambling on unstable video.

Test failure, not just success

Pull the network connection from the primary streaming machine for a moment. Confirm that the local recording continues if that is part of the plan.

Know where the backup presentation is. Know who can put up a holding slide. Have a direct communication route between the person running the platform and the production team.

The point isn't to create drama during rehearsal. It is to remove it from the live event.

Finish with responsibilities

In the final few minutes, make sure everybody knows who has authority to make a decision.

Who starts the broadcast? Who talks to the presenter? Who handles an attendee who cannot join? Who decides to switch to the backup connection? Who contacts a missing remote speaker?

Thirty minutes will not solve every possible problem. It will, however, expose a remarkable number of avoidable ones.

A rehearsal should leave the team slightly bored. Boring is good. Save the excitement for the audience.
