Learning goals
  • I can identify technical, symbolic and written codes in media texts.
  • I can use terms for camera movement, editing, mise-en-scène and diegetic/non-diegetic sound.
  • I can explain how conventions and techniques convey meaning and influence an audience, including when conventions are broken.

Words to know

technical codes
Production tools such as camera work, lighting, editing and sound.
symbolic codes
Elements that carry meaning beyond themselves: colour, costume, objects, setting, body language.
written codes
Words in a media text: titles, captions, headlines, labels and typography.
mise-en-scène
Everything placed in the frame: setting, props, costume, lighting and actors' positions.
diegetic / non-diegetic sound
Sound from inside the story world / sound added only for the audience.
continuity editing
Editing that hides cuts so action flows smoothly; includes the 180-degree rule and shot/reverse shot.
Kuleshov effect
The way viewers' reading of a shot changes depending on the shots around it.
genre convention
A pattern of codes audiences expect in a genre, such as low-key lighting in horror.

Remember from Grade 9

In Grade 9 you learned shot sizes (extreme long shot to close-up), camera angles (high, low, eye level), lighting, colour, music, editing pace and typography, and you wrote technique + evidence + effect sentences. In Grade 10 you'll organize techniques into codes, add new tools (camera movement, continuity editing, diegetic sound, mise-en-scène) and explain how they convey meaning and influence audiences.

Hook: same face, different feelings

Around a hundred years ago, the Soviet filmmaker Lev Kuleshov ran a famous editing experiment. He took the same shot of an actor's calm, neutral face and placed it after different images, such as a bowl of soup. According to accounts by Kuleshov and his student Vsevolod Pudovkin, audiences saw different emotions in the actor's face, such as hunger after the soup, even though the face shot was identical every time. (The original film is lost, and later researchers have re-tested the effect with mixed but generally supportive results.)

This is the Kuleshov effect: meaning comes not only from each shot, but from how shots are put together. Media have a language, and editing is part of its grammar.

Three kinds of codes

Media scholars often sort media language into codes:

  • Technical codes: the tools of production: camera (shot size, angle, movement), lighting, editing and sound.
  • Symbolic codes: what things mean beyond themselves: colour, costume, objects, setting, body language and facial expression. A character in a crisp suit at a glass desk signals power.
  • Written codes: words on screen or page: titles, captions, headlines, labels, typography.

When these codes are used in expected ways in a form or genre, they become conventions.

New technical tools

Camera movement

  • Pan: the camera turns side to side, revealing a scene or following action.
  • Tilt: the camera tilts up or down, for example up a tall building to show its size.
  • Tracking (dolly) shot: the camera moves along with a subject, pulling viewers into the action.
  • Zoom: the lens changes focal length to move closer or farther without moving the camera.
  • Handheld: shaky, personal, urgent; common in documentaries and action scenes.

Mise-en-scène (say it meez-on-SEN): everything placed in the frame: setting, props, costume, lighting, and where actors stand. Directors use it to tell you about characters before anyone speaks.

Editing

  • Continuity editing hides the cuts so the story flows; the 180-degree rule and shot/reverse shot keep conversations clear.
  • Cross-cutting switches between two places to build suspense or comparison.
  • Montage compresses time (a training sequence) or links ideas.
  • Match cut: cuts between two shots with similar shapes or movements to connect them.
the 180-degree lineABShot/reverse shot: all cameras stay on ONE sidecamera 1camera 2camera 3camera sidedo not crossto this side
The 180-degree rule keeps cameras on one side of an imaginary line between two characters. A always appears on one side of the screen and B on the other, so viewers stay oriented during a conversation. Cameras 2 and 3 film the shot/reverse shot.

Sound

  • Diegetic sound exists in the story world (dialogue, footsteps, a radio playing).
  • Non-diegetic sound is added for the audience (the score, a narrator).
  • A sound bridge carries sound from one scene into the next to link them.
  • Foley is everyday sound recorded in a studio to match the action, like footsteps and rustling coats.
STORY WORLDDIEGETIC sound: characters can hear itdialogueskates scraping icea car radio playingwind in the treesOUTSIDE THE STORYNON-DIEGETIC: onlythe audience hears itbackground scorenarrator voice-overtransition "whoosh"
Diegetic sound comes from inside the story world; non-diegetic sound is added for the audience only. A song that starts on a car radio (diegetic) and swells into the score (non-diegetic) blurs the line on purpose.

Genre conventions, and breaking them

Genres combine codes into recognizable patterns:

  • Horror: low-key lighting (strong shadows), discordant music, slow tracking shots down hallways, sudden silence before a scare.
  • Romantic comedy: bright high-key lighting, a "meet-cute," upbeat music, a final scene that brings the couple together.
  • Documentary: interviews, B-roll (extra footage that illustrates what's being said), archival images, voice-over, on-screen names and titles.
  • Sports broadcast: multiple camera angles, slow-motion replays, on-screen scores, commentators.

Creators follow conventions to meet expectations and break them to surprise or to make a point. A horror film set in bright daylight unsettles because it breaks the dark-hallway convention.

Worked example

Let's analyze a scene's codes

An invented four-shot scene from a short film called The Last Bus: (1) Extreme long shot, night: a single teen at a snowy bus shelter under one streetlight. Wind howls. (2) Close-up of the teen's phone: 1% battery. A slow, low piano score begins. (3) Tracking shot following headlights approaching through the snow; the piano stops. (4) Medium shot, eye level: the bus door opens with a hiss; warm yellow light spills onto the teen's face; the driver says, "Hop in. You look frozen." Identify the codes and explain how they convey meaning and influence the audience.

  1. Shot 1: the extreme long shot makes the teen tiny and alone. The single streetlight is symbolic (a small island of safety). The howling wind is diegetic sound that makes the cold felt.
  2. Shot 2: the close-up on 1% battery (a written code on screen) shows the stakes: no way to call for help. The non-diegetic piano tells the audience how to feel: lonely, worried.
  3. Shot 3: the tracking shot pulls us toward the headlights; the piano stopping creates suspense (Is this the bus? Is it someone else?). This uses the convention of silence before a moment of change.
  4. Shot 4: an eye-level medium shot shows driver and teen as equals. Warm light (symbolic code: warmth, safety) replaces the cold blue night. The dialogue resolves the tension.
  5. Overall effect: codes move the audience from isolation and anxiety to relief and human kindness. The short film's implied message: small acts of care matter.

Technical codes (shot size, tracking, sound), symbolic codes (single streetlight, warm light) and written codes (1% battery) work together to move the audience from fear to relief, conveying a message about kindness.

Just for fun

Funny-but-true: a classic Foley trick for footsteps in snow is squeezing a pouch of cornstarch. So in some movies, the crunchy winter walk you hear was really someone squishing baking supplies in a studio.

Hands-on activity

Silent scene, sound scene

You need: a device to watch a short film clip or TV scene (about 1 to 2 minutes, with a grown-up's OK), paper and a pen. Optional: a phone to film your own three-shot scene.

  1. Watch the clip with the sound off. Note the technical codes (shots, angles, movement, editing) and symbolic codes (colour, costume, props, setting).
  2. Watch again with the sound on. Label each sound diegetic or non-diegetic. What did the sound add?
  3. Identify the genre and two conventions it follows or breaks.
  4. Optional: film your own three-shot scene at home (for example someone getting ready to go out in the snow) using one camera movement and one deliberate sound choice. Respect the 180-degree rule if two people talk.
  5. Write three technique + evidence + effect sentences about the clip or your scene.

What to look for: correct use of the new terms (pan, tilt, tracking, mise-en-scène, diegetic), at least one point about how sound changes meaning, and effect statements that explain how the audience is influenced.

For parents and teachers

What this lesson teaches: expectation 2.2: identifying conventions and techniques in a variety of media forms and explaining how they convey meaning and influence audiences. Students organize techniques into technical, symbolic and written codes, and learn camera movement, mise-en-scène, continuity editing, the Kuleshov effect, diegetic and non-diegetic sound, and genre conventions.

How to help at home:

  • Watch a scene together with the sound off, then on. Talk about what the music changed.
  • Pause a film and ask: "What's in the frame, and why?"
  • Guess a film's genre from the first 30 seconds.

Common difficulties:

  • Naming techniques without effects. Always add so the audience feels/thinks...
  • Diegetic confusion: ask "Could the characters hear it?"

Facts used: Lev Kuleshov was a Soviet filmmaker whose editing experiments date from around 1920. Foley is named after sound-effects artist Jack Foley; cornstarch in a pouch is a classic Foley trick for snow footsteps. The Last Bus is an invented example.
