Before You Book a Vision Mixer: A Checklist for Multi-Camera Shows
A working list of questions to settle with your producer and director before choosing who will cut your live multi-camera show, from camera count to rehearsal time and talkback.
Start with the show, not the equipment
Before anyone talks about switchers, settle what the programme actually is. A studio panel with four seated guests asks for very different cutting than a concert with a roaming camera, a crane and a fast-moving set list. Write down the format, the running time, the number of cameras and whether the director expects the vision mixer to follow a full script or to cut by ear and instinct.
I run replay and graphics, so I sit beside the vision mixer on many bookings and see how much hangs on this first conversation. When the brief is vague, the operator spends rehearsal guessing at intentions. When it is clear, rehearsal goes into timing and polish. A page of notes shared a week ahead is often enough to change the whole day.
Also say honestly whether the show is new or part of a series. A returning format has habits the operator can learn quickly; a first outing needs more room to settle.
- Format, running time and expected number of cameras
- Scripted cues or a looser, director-led cut
- New format or a returning series
- Any guests, performers or presenters who move around the set
Check the camera count and what each one does
Camera count shapes the whole job. Three cameras can be cut cleanly by one person with a simple plan. Eight cameras, plus a robotic head and a couple of remote sources, ask for a clearer map of who covers what, and a vision mixer who has worked at that scale before.
Ask for a camera plan, even a rough sketch. Which camera holds the wide, which takes the close on the presenter, which is reserved for audience reaction. If operators are new to one another, agree shot names early so the director's calls mean the same thing to everyone in the gallery.
It also helps to say which cameras are likely to be unreliable. A long cable run, a handheld on a battery or a wireless link can all drop out, and the operator should know in advance which sources they can lean on when the show is at its busiest.
- A simple camera plan showing position and purpose
- Agreed shot names shared with camera operators
- Remote or wireless sources flagged as less certain
Confirm the switcher and the inputs you already have
If you own or hire a switcher, tell the operator the make, the number of inputs and outputs, and how the router or monitoring is arranged. An experienced vision mixer can adapt to most desks, but a familiar surface saves rehearsal time, and an unfamiliar one deserves a short session before the day.
Check that the inputs match the show. Count the cameras, then add graphics, replay, playback, any guest video link and a clean spare. It is common to find a plan that needs eleven sources on a desk that offers ten.
Ask also about the programme and preview outputs, the multiviewer and where the operator will look. Poor monitoring makes even a calm operator miss a cue, and it is far easier to fix on a Tuesday afternoon than ten minutes before transmission.
- Switcher model, inputs, outputs and any router
- Total sources including graphics, replay and playback
- Multiviewer layout and monitor positions
- A spare input kept clear for emergencies
Plan rehearsal time and a way to talk
Cutting well depends on rehearsal more than most clients expect. Even a short run-through lets the operator learn the director's rhythm, find the awkward moves and notice where the script leaves gaps. If the budget allows only one rehearsal, spend it on the hardest ten minutes of the show rather than the opening.
Talkback deserves its own check. The vision mixer needs to hear the director clearly and, ideally, to be able to reply without leaving the programme feed. Agree who speaks, when, and how calls are phrased. Short, consistent calls work better than long explanations during a live cut.
If cameras, graphics and replay are all on separate comms channels, someone needs to know who hears what. Writing this down on a single sheet avoids a surprising amount of confusion once the red light is on.
- Rehearsal slot with the real cameras and graphics
- Talkback channels and who can speak on each
- A short, agreed set of director calls
Ask what happens when something fails
Live television rarely runs without a fault, so ask how the operator handles one. A camera freezes, a graphic fails to key, a feed drops for two seconds. A good vision mixer has a calm default: cover with the safest source, tell the director, and fix the rest after the cut is safe.
Agree the fallbacks in advance. Which camera is the safe wide? Is there a clean slate or holding graphic ready? Who decides to go to it? These are small decisions, but they are much easier made over coffee than in the middle of a transmission.
Finally, ask who is responsible if the director is delayed or the script changes late. Clear responsibility keeps the gallery quiet, and a quiet gallery is usually the sign of a well-run show.
- A named safe source and a holding graphic
- Who decides to switch to a fallback
- What happens if the script changes late
Settle the practical details in writing
Last, put the logistics on paper. Call time, load-in, meal breaks, finish time, the venue's access and where the gallery sits all affect how well an operator can work. A vision mixer who arrives to find the desk still in cases and the monitors unplugged starts the day already behind.
Confirm what the booking includes and what would change it, such as a longer day, an extra rehearsal or a second show on the same booking. The prices page sets this out for our own work, and a written confirmation after your enquiry keeps both sides clear.
Then read the list once more with your director. If any answer is still unknown, that is the thing to resolve before you decide, not after.
- Call time, load-in and finish time
- Gallery location and venue access
- What the booking covers and what changes it
A multi-camera show is cut by people, and a good cut starts well before the first shot is taken. Work through the format, the cameras, the desk, rehearsal, talkback, fallbacks and logistics, and you will know what to ask any vision mixer you consider. If you would like to talk it through, send an enquiry on the contact page and we will go over the list with you.
