The Tools Behind a Useful Dress Rehearsal and Written Checklist

Why the method matters more than the gear

When learners arrive, many assume the hard part of a multi-camera show is the equipment. After a few weeks of rehearsals, most change their minds. The cameras, the mixer and the encoder usually work. What fails is the order in which people check them, and the habit of trusting something that worked last month.

In the audio routing sessions I teach, the same pattern repeats. Someone checks the microphone levels at the desk, sees movement on the meter and moves on. Nobody listens to what the stream itself is carrying. The method we rely on closes that gap by making every check a written, ordered step rather than a feeling that things look fine.

This note covers the working tools of that method: the printed checklist, the run sheet, the test sources and the timer. None of them is expensive. All of them can be used by a small studio or a panel event team without extra staff.

The written checklist as the main instrument

The checklist is a single sheet, printed, kept on a clipboard beside the switcher. We insist on paper because a screen can freeze, sleep or be covered by the very software you are checking. Each line is a short instruction with a box: camera one framed, camera two white balance matched, microphone three unmuted in the mix.

The list follows the signal path rather than the importance of each item. It begins at the cameras, moves through the switcher and the mixer, then the encoder, and finishes at the platform page. Following the path means you never skip a stage because it felt boring.

Learners write their own version in the second week, after seeing how the sample sheet is built. A list you wrote yourself, after a rehearsal that went wrong, is read carefully. A list handed to you tends to be ticked from memory.

• Order lines by signal path, from camera to platform
• Keep one action per line, written as a command
• Leave a column for the name of whoever checked it

Run sheet, timer and cue notes

Beside the checklist sits the run sheet. It lists the show in segments with a rough duration, the scene to be on air, which microphones are live and who speaks. During a rehearsal it is the document that exposes problems that the equipment tests cannot, such as a presenter who walks out of frame during a handover.

We also use a simple countdown timer, visible to everyone at the desk. Rehearsing to a clock shows whether a segment really fits its slot, and it teaches the operator to prepare the next scene while the current one is still running.

Cue notes are short pencilled marks on the run sheet: a volume to raise, a lower-third to bring in, a camera to reframe. They are the part learners most often skip and most often thank us for after the first full run.

Test sources and listening on the real output

A dress rehearsal is only honest if it passes through the same path as the show. That means sending a private or unlisted test stream to the real destination platform, then watching and listening on a separate device, such as a phone on another connection, as an audience member would.

For sound, we keep a short spoken test file and a steady tone available at the mixer. Playing them through the whole chain shows quickly whether a channel is delayed, clipped or routed to the wrong bus. Headphones at the desk tell you what the desk hears. The second device tells you what the viewer hears.

Platform settings differ, and what an ingest accepts can change over time, so we treat the platform page as part of the checklist, not a fixed fact to be remembered. Results also depend on the venue connection, which a rehearsal on site is the only way to learn.

• Stream privately to the real destination
• Watch and listen on a second device and network
• Play a spoken test file through every audio channel

Reading the rehearsal back

Where possible, we record the rehearsal output and watch it afterwards with the crew, rather than relying on memory. Recordings show things nobody noticed live: a scene change that lingered a second too long, a microphone that popped on opening, a caption that covered a face.

After the viewing, learners mark each fault on the checklist or run sheet and decide whether it needs a new line, a new cue or a change to the setup. Sometimes the answer is a better position for a table microphone. Sometimes it is simply allowing five more minutes before going live.

Over a few rehearsals the sheet gets shorter in problems and longer in useful detail. That is the sign the method is working: the show becomes boring to run, which is exactly what a viewer wants from the other side of the screen.

Keeping the kit simple and portable

Everything described here fits in one bag: a clipboard, a few printed sheets, pencils, a small timer, a pair of headphones and a spare cable of each type used in the show. We encourage learners to keep that bag packed and checked, so the dress rehearsal can begin without a search for basic items.

Simple tools also travel between venues. A panel event in a rented room and a studio session at home use the same sheet with different details filled in. That repeatability is the practical benefit, because the team stops reinventing its routine each time.

The aim is never a perfect stream, which no method can promise. The aim is that when something does go wrong, the team knows where to look first and has already seen the failure once before an audience arrived.
