Every profession has its jargon – and film and television have some of the quaintest.

We all know what a Best Man is, but what’s a Best Boy?

Are Redheads brighter than Blondes?

Is a Travelling Matte the same as a magic carpet?

Is a Butterfly Frame really used for catching moths?

Read on to find out what they, and all sorts of other trivia, mean (Except for the bits I forgot).

Aerial Shot
A shot taken from a high building, crane, plane, helicopter or drone. Not necessarily a moving shot.

The noise that is in the background of the sounds you want to record. Americans call it ‘Room Tone’.

Anamorphic lens
Squeezes wide screen shots onto normal geometry film. A similar lens in the projector expands the shot horizontally again.

The variable opening that controls the amount of light entering the camera.

Art director
See Designer

Aspect Ratio
The ratio of width to height of a picture. Normal television is 4×3 and wide screen television is 16×9. The cinema uses all sorts of different formats, but the standard frame is 1.85×1.

Assistant director / First assistant
The person who directs additional action in shots, who runs rehearsals, and generally assists the director in the production process. Responsible for keeping communications flowing on the unit. Chief smoother of ruffled feathers.

Associate Producer
Someone who arranged for his brother-in-law to let the production borrow his holiday bungalow for a shoot.

Atmos Track
See Buzz Track

The process of assessing actors and actresses for certain parts in a production.

Background music
Music which is added to the film and not recorded as the film is being shot. Intended to heighten the mood of the production.

The light behind the subject which separates it from the background and gives the shot depth.

Back Projection
A system whereby a fixed or moving image is projected onto a translucent screen behind the main action. Mostly superseded by matte processes.

Barn Doors
Metal flaps attached to the front of a lamp that give the user much more selectivity over the lighting.

Best Boy
Term used by the lighting gaffer and the senior grip for their number two. Originates from an apocryphal conversation between a cameraman and a gaffer. The cameraman wanted a very complicated set up. He said it was not a job for a junior person. “Right,” says the gaffer, “I’ll put my best boy onto it”.

Big Close-up
Very close shot of the face, cutting off the top of the head.

Black edging
Outlining letters on screen to help legibility.

Smallish portable mains lamp, about 2 kilowatts of power. Also a hand-held device wielded by a producer to demonstrate his importance.

Long pole used to mount microphones above people’s heads and out of shot. The holder of the pole is the boom operator, sometimes also called boom.

Bounced Light

Bridging Shot
A shot used to cover a jump in time or place or other discontinuity. Common examples are falling leaves, changing calendar pages and newspaper headlines.

Broadcast Quality
A special technical term used to describe the output of a manufacturer’s product no matter how badly it works.

Very large bright light, usually carbon arc.

Buffer shot
A cheat shot put in to disguise a crossing line error. See Crossing the line.

Large frame used to mount a diffusion screen to control light.

Buzz Track

Camera Angle
The vertical angle at which the camera is pointed at the subject.

Cardioid Microphone
One with a directional pattern of sound pickup. A diagram of the acceptance pattern is heart-shaped or cardioid.

The people who actually play parts in a production.

See Colour Separation Overlay.

The colour part of a video signal.

The person in charge of how the photographic end of a film looks. He decides where lights go, what filters to use, etc. On large crews he might have six or more assistants as well as the electricians and grips. On small crews he do all of these jobs himself.

Clapper board
A board marked with the shot number and take (plus other information about the production). It is usually recorded at the start of each shot, and helps the editor find the preferred shot, and synchronise separate sound and vision sources.

The part of an action or drama movie when tension comes to its highest point, usually near the end.

A shot in which a character’s face and shoulders are the main image, or where a single object or parts of objects are the main image.

Colour Balance
Generally you want to make sure that white looks white, not pale blue or yellow. Sunlight, fluorescent bulbs, tungsten bulbs, gas lamps give different kinds of light. The eye adapts automatically, but a camera has to be filtered and/or electrically adjusted to make white look white.

Colour Separation Overlay (CSO)
An electronic system for combining two images so that one appears to have the other as a background. At its simplest, a plain (usually blue) coloured background in the first shot operates an electronic. Where the switch sees blue, it puts in part of shot two; any other colour and it leaves in the original shot 1 On film it is called travelling matte or blue (green) screen process.

Colour Temperature
A measurement of the colour of light. Daylight is very blue, tungsten (ordinary household bulbs) is pinky-yellow, and most fluorescents are greenish. How blue they are is measured in degrees Kelvin, and filters can then be used to change the apparent colour.

Spoken words by an invisible narrator. The words add information to the pictures. Found mostly in documentary films, but occasionally in dramatic, epic or docudrama.

Component Video
A video signal in which the Luminance and Chrominance parts are kept separate. This requires a higher bandwidth, but gives a better quality picture.

Composite Video
The luminance and chrominance signals are combined.

Electronic device for increasing and decreasing the volume of a sound to bring it within a certain range.

Contrast Ratio
The difference between the lightest and darkest parts of a shot. The human eye can see into the darkest shadow on the brightest day – a ratio of maybe two thousand to one. Video can handle about 75 to 1.

Making sure that all details of a scene or location are consistent from shot to shot.

Continuity cuts
These are cuts that take us seamlessly and logically from one sequence or scene to another. This is an unobtrusive cut that serves to move the narrative along.

A list of people involved in making a programme. The rules for who goes where in the list are enormously complex, but for a television programme at its simplest, the order is; leading on-screen people, minor on-screen parts, minor off-screen, then major off-screen ending with the director.

Crossing the line
Reversing the action (direction of travel or eyeline) in successive shots. This confuses the viewer’s sense of direction.

1 Cutting between two different actions, either occurring simultaneously or at different times. These scenes are often referred to as parallel action. Crosscutting is used to build suspense, or to show the relationship between the different sets of action.
2 Also used to refer to cutting between two people in one scene.

The joining of one shot to another. In its simplest form the cut imitates the way the eye switches between images.

A shot of something or someone related to, but not seen in, the main shot. It can help to shorten time, or to avoid a jump cut.
