Sound and Editing
Film is an art of time. Editing controls when we see something and how long we stay with it; sound controls what we hear and what we feel before we understand why. A cut can create a shock, a joke or a connection. A silence can be louder than a score. Analysing sound and editing means noticing the rhythm of the film, not only its images.
Sound
| Sound element | What it is | Possible effect |
|---|---|---|
| Dialogue | Words spoken by characters. | Reveals character, conflict and information. |
| Diegetic sound | Sound whose source is in the story world. | Creates realism and place. |
| Non-diegetic sound | Sound added for the viewer, such as a score. | Guides emotion and interpretation. |
| Score | Composed music accompanying the images. | Creates mood, continuity and memory. |
| Ambient sound | Background sound of a place. | Establishes environment and texture. |
| Foley | Recorded everyday sounds added in post-production. | Makes action feel physical and close. |
| Silence | The absence or near-absence of sound. | Creates tension, intimacy, shock or grief. |
| Voice-over | A voice speaking over the images. | Provides reflection, memory or authority. |
| Sound bridge | Sound that carries across a cut. | Connects spaces or times. |
Editing
| Edit | What it does | Possible effect |
|---|---|---|
| Cut | Moves directly from one shot to the next. | Creates pace, contrast or continuity. |
| Match cut | Connects two shots through a similar shape, action or sound. | Suggests a relationship or a passage of time. |
| Jump cut | Creates a visible discontinuity in time or space. | Suggests unease, urgency or fragmentation. |
| Dissolve | One image fades into another. | Shows time passing, memory or connection. |
| Fade | Image moves to or from black. | Marks a beginning, ending or emotional pause. |
| Montage | A sequence of shots compressed into a passage of time. | Builds an idea, routine or transformation. |
| Cross-cutting | Alternates between two actions. | Creates suspense, comparison or irony. |
| Long take | Holds a shot without cutting. | Creates realism, tension or discomfort. |
| Slow motion | Slows the image below normal speed. | Emphasises a moment or creates dreamlike distance. |
| Fast motion | Speeds up the image. | Creates comedy, urgency or alienation. |
Rhythm and duration
Editing is not only about the cut; it is also about how long a shot is held. A long take can make the viewer wait, creating tension or intimacy. A rapid series of short shots can create panic, energy or fragmentation. A film may slow down at a moment of grief and speed up during a journey. Ask what the film wants the viewer to feel in time, not just what happens in space.
Worked example: the bus stop
An original teaching example: a fictional scene shows a teenager waiting for a bus after an argument at home.
| Choice | Effect |
|---|---|
| Long shot of the empty road | Emphasises waiting and isolation. |
| Close-up of the timetable | Shows the gap between the promised time and the actual wait. |
| Diegetic sound of insects and distant traffic | Makes the silence feel physical. |
| No score | Refuses to sentimentalise the teenager's loneliness. |
| Cut to the bus arriving without warning | Creates a small release after the wait. |
| Hold on the empty seat beside him | Suggests the argument is still present. |

Common errors
- Ignoring sound. Analysing only the image in a medium that is half sound.
- Music equals emotion. Assuming a score's meaning is obvious or universal.
- Cut counting. Listing edits without explaining rhythm or connection.
- Confusing diegetic and non-diegetic sound. Misidentifying the source of a sound.
- Missing silence. Treating absence of sound as absence of meaning.
- Forgetting the long take. Assuming that editing always means cutting.
- No timecode. Making a claim about a sequence the reader cannot find.
Next, examine dialogue and voice.
