Switcher Training

Video
Switching

You decide what the room and the stream actually see. Every cut either keeps the viewer inside the moment, or reminds them there is a camera.

Program, Preview, and the Cut

You decide what the room and the stream actually see, and when. This page covers how to build a cut that no one notices.

Camera operators have their own manual — see Camera Operator in the contents. If you are switching, the section there on Understanding Your Director is worth reading too, since it is the same relationship from the other side.

We run two rooms on two different desks. Worship Center is on a Ross Carbonite; Worship East is on a Blackmagic ATEM. The principles below are identical on both — only the button names differ, and those are split out at the end.

Program and Preview

Every switcher has two rows that matter. Program is what is going out right now. Preview is what you have queued to go next. Your whole job is a rhythm: look at Program, decide what should follow, set it on Preview, take it.

The discipline that separates a clean switch from a messy one is simple: never take a shot you have not looked at on Preview first. A camera that was framed perfectly ninety seconds ago may be mid-adjustment now. Preview is where you find that out; Program is where the congregation finds out.

The standing habit

Set Preview the moment you take. The gap between taking a shot and queuing the next one is where you get caught out — if the moment comes early, you want the next shot already sitting there.

Cut or dissolve

A cut is instant and keeps the viewer inside the action. A dissolve holds both pictures on screen for its duration and reads as a passage of time or a change of place.

Cut for most of the service. Cuts are invisible when they land in the right place, and the right place is mid-sentence, in the pause where a speaker is turning a thought over — not at the start of a sentence, which draws attention to the edit. During worship, cut on the beat or on a musical phrase boundary.

Dissolve when the moment actually changes. Coming out of worship into the message, into and out of a prayer, into a video roll, or at the top and tail of the service. A dissolve used as decoration reads as soft; a dissolve used to mark a real transition reads as intentional.

One practical consequence for the cameras: a dissolve shows both pictures at once, so any camera movement during one is visible over the top of the other shot. If you know a dissolve is coming, take it from and to cameras that are locked off.

Pacing

Your foremost job is controlling energy, and pacing is your main lever. Fast cutting adds energy; long holds let a moment breathe. The trap is that if everything is fast, nothing is — a chorus only feels like a lift if the verse before it was calmer.

Rough guide, to be broken when the moment calls for it:

Think three cuts ahead

Going into a chorus, you may need a four-shot sequence. Give one operator two instructions in a row, then cover the gap with two other cameras while they reposition. That way the big shot is ready on the beat rather than a bar late.

This is also why you should never call a shot and take it immediately. Give the operator time to make the move and settle. If you take them while they are still moving, you have put their correction on screen.

Protecting the operators

A few habits that make the cameras better:

  • Say the camera number first. "Cam 2, go tight on the speaker" — the number tells them to listen before the instruction arrives.
  • Do not stack calls on one camera. If Cam 2 is repositioning, do not give them a second change until the first has landed, unless you are deliberately building a sequence and know they are off air.
  • Warn before you take a moving camera. If you must take a camera that is mid-move, say so, so they can settle rather than continue.
  • Remember Worship East has no tally lights. Those operators cannot see when they are live, so they are relying entirely on you being predictable.

Graphics and keys

Lower thirds and side graphics ride on a keyer over Program. Two things to watch:

Frame first, key second. A lower third covers the bottom of the frame, so the camera under it needs to be a cowboy shot or wider. Keying an L3 over a tight shot puts the graphic across the speaker's chest.

Side graphics shift the picture. During announcements the switcher pushes Program to the right to make room for the panel. Operators are told to keep the subject centered for exactly this reason — but check the output, because a shot that was framed slightly left ends up under the graphic.

Worship Center — Ross Carbonite

  • Program and Preview are the two main crosspoint rows; select the source on Preview, then TAKE for a cut or AUTO for a dissolve at the set rate.
  • Set your transition rate before the service and leave it. A 15–20 frame dissolve suits worship; anything longer starts to feel like a fade.
  • Lower thirds live on the keyers — arm the key, then use the key's own transition rather than cutting it on hard.
  • The M/E gives you a place to build a composite before it hits Program. Build there, check it, then bring it up.

Worship East — Blackmagic ATEM

  • Same two rows: Program (top) and Preview (bottom). CUT takes instantly; AUTO runs the transition at the rate set in the transition panel.
  • Check the transition type is set to MIX before the service. It is easy to leave it on a wipe or DVE from a previous event, and discovering that live is unpleasant.
  • Lower thirds run on DSK 1 — use the DSK's own AUTO so the graphic fades rather than pops.
  • FTB (fade to black) is your safety. If something goes badly wrong, black is always better than showing the room something it should not see.
Both rooms, before you start

Confirm every camera is up on Preview and correctly labelled, the transition is set to a mix at the rate you want, the graphics are loaded and keyed to the right layer, and you know who is on which camera. Two minutes of this prevents most of what goes wrong live.

Glossary

The words you will hear on the headset. Terms marked house are ours — useful here, but not what an outside director will necessarily mean.

Aperture / iris
The opening in the lens that admits light, measured in f-stops. A smaller f-number is a wider opening: f/1.4 is wide open, f/16 nearly closed. Opening the iris brightens the picture and thins the depth of field.
Cowboy shot
A frame cut at mid-thigh, named for westerns where the crop fell at the gunfighter's holster. We use it to leave room for lower-third graphics.
Depth of field
The distance from the nearest to the furthest point that looks acceptably sharp. It gets thinner as you open the iris or zoom in, and deeper as you focus farther away or stop down.
Dissolve
A transition where one shot fades through into the next, holding both pictures on screen at once. Denotes a passage of time; a cut keeps you inside the action.
Cut
An instant change from one camera to another.
ENG camera
Electronic News Gathering — the shoulder-mount broadcast body we use. Ours have 2/3″ sensors and a 16× zoom.
Focal plane
The exact distance from the camera that is critically in focus. The depth of field is the tolerance either side of it.
Focus handle
The grip on the lens barrel that sets focus. Turning it away from your body pushes the focal plane farther from the camera.
Smooth Follow
The default follow style: let the speaker get a head start, then ramp up and ramp down to bring him back toward center. Mirrors natural conversation, and is what you use most of the service.
Tight Follow
The tighter follow style: anticipate the speaker and hold him near center, with a little space opened behind him. Reads as more immediate, so it is kept for moments of rising energy.
Follow
Keeping a moving subject framed by panning with them.
Headroom
The space between the top of the head and the top of the frame. In our 16:9 frames, set it by placing the eyes on the upper third line.
IMAG
Image Magnification — the feed to the screens in the room, for people who are present but seated far back. Wants clarity and detail, where the broadcast feed wants more of the room.
Lower third / L3
A graphic across the bottom of the frame carrying a name, title, or event details. Frame a cowboy shot so it has room.
Lead room / looking room / nose room
Standard practice: space left on the side the subject faces, so they look into the frame rather than into its edge. Note our Tight Follow style deliberately weights the opposite way.
Pan
Pivoting the camera horizontally on the tripod head. (Moving the whole camera sideways is a truck; raising or lowering it is a pedestal. We rarely do either on sticks.)
Pillowing house
Easing into and out of a move rather than starting and stopping abruptly — the "approaching an intersection" feel. Both follow styles use it.
Rack focus
Deliberately shifting focus from one subject to another while recording.
2/3″ sensor
The imager size in our ENG bodies. Small sensors give much deeper depth of field than large-sensor cinema cameras — forgiving for focus, but background blur is correspondingly hard to achieve.
Sharp zone
Plain-language name for the depth of field as drawn in this manual's diagrams.
Switcher
The desk that selects which camera goes to air and adds graphics. During announcements it shifts your picture sideways to make room for a side graphic. Worship Center runs a Ross Carbonite; Worship East runs a Blackmagic ATEM.
Program
What is going out to air right now. The row on the switcher that feeds the room and the stream.
Preview
The shot queued to go next, checked before it goes live. Never take a shot you have not seen on Preview.
Take
To put the Preview shot on Program. Called TAKE on the Carbonite and CUT on the ATEM.
Auto
The button that performs the transition over the set duration rather than instantly — a dissolve where a cut would be immediate.
DSK / keyer
Downstream keyer — the layer that puts graphics such as a lower third over Program without changing the camera underneath.
FTB
Fade to black. The switcher's emergency stop: when something goes wrong, black is better than showing the room something it should not see.
M/E
Mix/Effects — a workspace on the switcher where a composite can be built and checked before it is brought up on Program.
Tally
The red light on the camera showing it is live to air. Tally on means make no adjustments. Worship Center cameras have tally lights; Worship East cameras do not — there you track what is live from the director's calls.
Tilt
Pivoting the camera vertically on the tripod head.
Zoom
Changing focal length to make the subject larger or smaller in frame. It is not a dolly — the camera does not move, so the perspective does not change. Zooming in also thins the depth of field.
