How Many Cameras Do You Really Need to Film an Event?
One camera records what happened. Several cameras can make the audience feel they were there.
It is very easy to assume that filming an event simply means putting a camera at the back of the room, pressing Record and allowing it to run until everyone goes home.
Technically, that works.
But there is a considerable difference between recording an event and producing an event video.
A single camera can preserve what happened.
Two cameras can begin to give the editor choices.
Three, four or five cameras can start to create a genuine sense of presence.
And with a sufficiently well-planned multi-camera production, somebody watching later can sometimes see rather more than a member of the original audience could see from their seat.
We were reminded of this recently when filming an organ concert.
We used five cameras.
That might initially sound excessive for somebody sitting at an organ, but the opposite was true. Each camera had a different job, and afterwards I could immediately see places where, given more physical space around the instrument, even more angles could have been useful.
The interesting question therefore is not:
"How many cameras should I use?"
It is:
"How many different things does my audience need to see?"
Start With the Simplest Option: One Camera
There is nothing inherently wrong with single-camera production.
For many events it may be entirely appropriate.
Imagine a lecturer standing at a lectern giving a 30-minute presentation.
A camera positioned centrally could record:
the speaker;
the lectern;
perhaps the projection screen;
and enough of the room to establish where the event is taking place.
That may be all that is required for an archive recording.
The enormous advantage is simplicity.
There is only one camera to position, one recording to manage and one picture to edit.
But the limitation becomes obvious surprisingly quickly.
Suppose the lecturer holds up a small component.
The audience in the room can look at it.
The camera at the back cannot.
Suppose somebody asks a question.
The camera remains pointed at the lecturer while the person speaking is somewhere behind it.
Suppose the lecturer turns to demonstrate something on a table.
The audience naturally changes where it is looking.
The camera does not.
That is one of the fundamental differences between human vision and a single fixed camera.
People automatically look towards the interesting thing. Cameras have to be told where the interesting thing is.
The Second Camera Changes Everything
Moving from one camera to two often produces a much greater improvement than people expect.
One camera can provide the safety shot.
The second can provide variety.
For example:
Camera 1 — Wide shot
Shows the stage, speaker, performer or demonstration area.
Camera 2 — Close-up
Shows the face, hands, instrument, product or detail being discussed.
Now the production can move between context and detail.
During a conference presentation, the wide shot may establish the room.
Then the programme cuts to a closer view when the speaker makes an important point.
During a craft demonstration, the wide camera shows the demonstrator while the second camera looks down onto the workbench.
During a musical performance, one camera can show the performer while another concentrates on the instrument.
Suddenly the viewer is no longer simply observing the room.
They are being guided through the event.
That distinction is enormously important.
Three Cameras Begin to Tell a Story
With three cameras the production becomes much more flexible.
A typical arrangement might be:
Camera 1 — Master wide shot
The dependable shot that always shows what is happening.
Camera 2 — Medium or close shot
Used for faces, gestures and expression.
Camera 3 — Detail or alternative angle
Hands, demonstrations, instruments, presentation material or audience reaction.
The wide shot is particularly important because it provides somewhere safe to cut.
If Camera 2 is being repositioned, refocused or adjusted, the director can return temporarily to Camera 1.
Then Camera 2 can be prepared for its next shot without the viewer ever seeing the movement.
This is one of the great advantages of multi-camera production.
Every camera does not have to be perfect every second.
It only has to be ready when it is selected.
Four or Five Cameras: Now We Are Building an Experience
Once we reach four or five cameras, we can begin thinking much more creatively.
This is where our recent organ concert provides a useful example.
From an ordinary audience seat, the organist may actually be quite difficult to see.
Depending upon the building and instrument, the player may be:
behind the console;
beneath a gallery;
facing away from the audience;
partly obscured by the instrument;
or positioned some distance from the seating.
Even when the organist is visible, many of the most interesting things are happening out of sight.
The hands may be moving between several keyboards.
The feet are playing the pedalboard.
Stops are being changed.
Pistons or registration controls are being operated.
Music is being followed.
All of this is fascinating to anyone interested in how an organ is actually played.
So for our concert we used five cameras.
That allowed us to show considerably more than one conventional camera could ever have shown.
A possible arrangement for this type of production might include:
Camera 1 — Main wide shot
Shows the performer and console in context.
This becomes the visual foundation of the production.
Camera 2 — Upper manual and hands
A tighter view of the keyboards shows the finger work.
With a complicated piece, this can be fascinating.
Camera 3 — Pedalboard
For many audience members, this is the revelation.
Unless you are an organist yourself, you may never have appreciated just how much is being played with the feet.
Camera 4 — Performer close-up
This provides expression and human connection.
A musical performance should not become nothing more than pictures of machinery.
Camera 5 — Alternative instrument or side angle
This might show stop changes, another keyboard angle or simply give the production visual variety.
That is already a substantial improvement over a conventional fixed-camera recording.
Yet afterwards it was easy to imagine additional possibilities.
More Cameras Do Not Necessarily Mean More of the Same
If the physical location had provided us with more space, cameras on both sides of the instrument could have created completely different views.
This is an important principle.
There is little benefit in using eight cameras if six of them essentially show the same thing.
The value comes from giving each camera a distinct visual purpose.
For an organ concert, additional positions might include:
left-hand keyboard angle;
right-hand keyboard angle;
stop controls;
pedalboard;
organist's face;
full console;
wide auditorium;
audience reaction.
Suddenly eight cameras no longer sounds particularly extravagant.
In fact, eight is the input limit of the ATEM Extreme ISO setup we use, so there is a very practical ceiling to how far the system can expand without changing the production infrastructure.
But even then, I would not automatically use all eight.
The objective is never:
"How can we fill every input?"
It is:
"Does this camera reveal something useful?"
The Camera the Viewer Does Not Notice May Be the Most Important
One of the least glamorous cameras in a multi-camera production is often the wide safety camera.
It may spend most of the event recording a comparatively unexciting view.
But it can be invaluable.
Suppose the close-up camera operator suddenly needs to move.
Suppose somebody walks in front of another camera.
Suppose autofocus briefly decides that the background is more interesting than the speaker.
Suppose the performer suddenly moves somewhere unexpected.
The director can cut immediately to the wide camera.
The audience watching the final programme may never know that anything went wrong.
Multi-camera production therefore does more than improve creativity.
It also provides redundancy.
That can be extremely valuable when an event cannot simply be repeated.
Events Only Happen Once
This is something I think becomes particularly important when filming real events.
If I am making a studio video and a camera fails, I can usually record the section again.
At a concert, conference, wedding, awards presentation or live demonstration, that may be impossible.
The keynote speaker will not necessarily repeat the last ten minutes because somebody accidentally disconnected an HDMI cable.
The musician will not stop halfway through the performance while we reposition a camera.
The award will not normally be presented for a second time.
Live production therefore requires a different mentality.
The recording system needs to be designed around the possibility that things will go wrong.
Multiple cameras give us alternatives.
Live Switching Changes the Way You Think
Connecting several cameras to a switcher such as an ATEM also changes the way an event can be produced.
Instead of thinking about five independent recordings, we can start thinking about a programme.
At any moment the director can choose which camera the viewer sees.
Wide shot.
Cut to the hands.
Cut to the pedals.
Back to the performer.
Then perhaps return to the wide shot at the end of the piece.
Done well, those changes follow the viewer's natural curiosity.
The viewer should rarely be thinking:
"Why am I looking at this?"
Ideally the picture changes just before they realise that they wanted to look somewhere else.
Live Switching Versus Editing Afterwards
There are two related but slightly different approaches.
You can create the finished programme live.
Or you can record all the individual cameras and refine the programme afterwards.
There are advantages to both.
Live switching
Excellent when:
the event is being streamed;
large screens are being used in the venue;
rapid delivery is required;
or the production team wants a near-finished programme immediately.
ISO recording
If the system records each camera separately as well as the programme output, post-production becomes much more powerful.
Perhaps I switched to the pedal camera half a second too late.
In the edit I can change it.
Perhaps another camera captured a wonderful reaction from the audience.
That can be inserted afterwards.
Perhaps one shot was slightly too long.
It can be shortened.
This combination of live direction plus separate camera recordings is particularly valuable.
The live switch provides the structure.
The individual recordings provide the opportunity to improve it.
The Audience Camera Is Often Forgotten
When people plan event coverage they naturally concentrate on the stage.
But sometimes the audience is part of the story.
Imagine a comedian delivering a punchline.
The performer's expression matters.
But so does the audience laughing.
At an awards ceremony, the recipient matters.
But so does the family's reaction.
At a product launch, the demonstration matters.
But seeing people respond to it can make the programme much more engaging.
At a concert, a brief view of an attentive audience can remind the online viewer that this really was a live occasion.
Audience shots need to be used intelligently and appropriately, particularly where privacy and permissions are concerned, but they can greatly increase the feeling of being present.
Demonstrations Need Their Own Camera
This is especially relevant to the sort of educational and practical work we regularly film.
Suppose someone is demonstrating a piece of equipment on a table.
The presenter may be perfectly visible from the front.
The demonstration may not be.
A dedicated overhead or close-up camera can transform the programme.
The production might switch between:
presenter;
equipment close-up;
overhead workbench;
presentation screen;
wide shot.
This is why camera count cannot really be decided purely by the number of people on stage.
One presenter might require five cameras.
Five people sitting around a discussion table might only require three.
It depends upon what needs to be seen.
Conferences Present a Different Challenge
Imagine a conference session containing:
a speaker;
a projection screen;
a product demonstration;
and questions from the audience.
A sensible system might use:
Camera 1: wide stage shot
Camera 2: speaker close-up
Camera 3: demonstration area
Camera 4: audience/question microphone
The presentation slides could potentially enter the video system directly rather than being filmed by another camera.
That distinction matters.
Sometimes adding another camera is not actually the best solution.
It may be better to connect the computer presentation directly into the switching system.
Good multi-camera production is really about sources, not merely cameras.
Training Videos Benefit Enormously From Multiple Angles
Training and instructional content is another area where additional cameras can justify themselves very quickly.
Imagine a technician demonstrating how to replace a component.
A single wide camera might show the technician clearly but make the component almost invisible.
A better arrangement could be:
wide presenter camera;
shoulder-level close-up;
overhead bench camera;
macro detail camera.
The viewer can then see not only what the instructor is doing but precisely how it is being done.
That can be the difference between an instructional video being interesting and actually being useful.
Five Cameras Can Still Produce a Bad Video
There is an important warning here.
More cameras do not automatically produce a better programme.
Poorly positioned cameras can create:
nearly identical shots;
distracting angles;
inconsistent colour;
confusing screen direction;
blocked sightlines;
visible operators;
unnecessary clutter.
Each camera needs a reason to exist.
Before an event I find it useful to think in terms of questions.
What must the audience always be able to see?
What detail might they want to see occasionally?
Which camera is the emergency safety shot?
Where will performers move?
Which positions might become obstructed once the audience arrives?
Are there moments when everybody will naturally look somewhere different?
Those questions often determine the camera positions more effectively than simply deciding upon a number.
Space Can Be More Limiting Than Technology
Our organ concert illustrated another practical problem.
Sometimes we have enough cameras.
What we do not have is enough places to put them.
A camera needs:
a clear line of sight;
somewhere physically safe;
access to power or sufficient battery;
an appropriate lens;
cabling if required;
and ideally a position that does not inconvenience the audience.
In a larger venue we might have positioned additional cameras on the opposite side of the organ.
That could have created much greater variety.
In a cramped location, however, another camera may simply give us another version of a view we already possess.
Location scouting therefore becomes extremely important.
Theoretical Camera Count Versus Practical Camera Count
There is also a point at which additional cameras begin to create additional problems.
Every camera requires some combination of:
setup;
alignment;
exposure matching;
white balance;
focus;
cabling;
recording media;
batteries;
monitoring;
file management;
synchronisation;
and post-production organisation.
Adding Camera 8 is not useful if managing Camera 8 makes Cameras 1–7 less reliable.
The ideal number is therefore not the maximum your equipment will support.
It is the maximum you can operate confidently and purposefully.
A Simple Camera-Planning Exercise
Before filming an event, try writing down every important thing the viewer might want to see.
For an organ concert, for example:
Whole performance area
Organist
Upper keyboards
Lower keyboards
Pedalboard
Stops and controls
Alternative side angle
Audience
That does not automatically mean eight cameras are required.
Perhaps one camera can cover several of those jobs.
Perhaps a remotely controlled camera can change framing.
Perhaps some views are important only occasionally.
But the exercise immediately reveals why a single camera may be inadequate.
So How Many Cameras Do You Really Need?
There is no single answer.
But as a useful starting point:
One camera
Suitable for:
simple archive recordings;
uncomplicated talks;
basic interviews;
static events.
Two cameras
A major improvement for:
interviews;
lectures;
simple performances;
demonstrations.
One provides security while the second provides detail.
Three cameras
Often a very effective minimum for polished event work:
wide;
close;
detail or alternative angle.
Four to five cameras
Excellent where there are several simultaneous areas of interest:
concerts;
demonstrations;
conferences;
training;
panel events;
performances.
Six to eight cameras
Potentially valuable for more ambitious productions where:
several performers are involved;
detailed actions need dedicated coverage;
both sides of the venue are useful;
audience reactions matter;
or the programme is being switched live.
But only if every camera has a job.
Think Like the Person Watching
Ultimately, multi-camera production is not really about cameras.
It is about attention.
When sitting in a live audience we constantly choose what to look at.
We look at the speaker's face.
Then the object they pick up.
Then the presentation screen.
Then somebody asking a question.
During a concert we look at the performer.
Then their hands.
Then perhaps the instrument.
A good multi-camera production performs those decisions on behalf of the viewer.
That is why several thoughtfully positioned cameras can make such an enormous difference.
Our recent organ concert used five.
In another building I could easily imagine using more, perhaps placing cameras on both sides of the console and adding still more detailed views.
Our ATEM system gives us a practical maximum of eight video inputs, and there are certainly productions where I could imagine making good use of all of them.
But the objective would never be to boast that eight cameras were being used.
The objective would be that the person watching the finished film never had to wonder what they were missing.
Conclusion — Don't Count Cameras. Count Viewpoints.
The wrong question is:
"How many cameras does a professional video need?"
The better question is:
"How many different viewpoints does this story need?"
Sometimes the answer will genuinely be one.
Sometimes it will be two.
Sometimes five will feel surprisingly modest.
A well-produced event video should allow somebody who was not in the room to understand not merely what happened, but what it felt like to be there.
And sometimes the cameras can do something even better.
They can take the viewer somewhere that the original audience could never physically have gone — directly above the keyboard, beside the performer or almost underneath the organist's feet.
One camera records what happened.
Several carefully chosen cameras can tell the story of what happened.
And that is a very different thing.
