How the story is told — editing rhythm, camera placement, pacing, information release. The crafted presentation, not the raw event.
On set, we talk about discourse when we discuss the way a story is revealed to the viewer — not what is told, but how it is told. That is the crucial difference. The raw action (protagonist enters room, finds letter) is not yet discourse. Discourse only arises through your camera movement, the editing sequence, the music, the timing between image and sound. You are thereby constructing a specific interpretation of the events.
Practically, this means: two different editors can assemble identical raw material in completely different ways, creating two opposing emotional or narrative meanings. Take a scene where a character is lying. If you cut immediately to their eyes (close-up of their uncertainty), it works one way. If you wait three seconds longer before cutting to the close-up, unease is created. Both times it's the same dialogue, the same action — but the discourse, the mediation, changes fundamentally. That's what we mean.
On set itself, discourse manifests in your compositional decisions: do you film a confrontation in shot-reverse-shot (classic, breaks down the scene into perspectives) or in a long take with a moving camera (tension, continuity, different perception)? Both techniques tell the same story, but with different authority and levels of meaning. The long take says: This is a continuous, unavoidable process. The cut says: There are conflicting truths here.
Discourse is also temporal: through editing rhythm, you determine how quickly or slowly information is revealed. Fast cuts in a chase scene are discourse. A 20-second static shot of an empty door is also discourse — it creates anticipation and dread. You are actively manipulating how the audience perceives the world, even though the world itself (the event) remains the same. This is the core concept: discourse is your voice as a filmmaker — not the voice of the character, not of reality, but your creative mediation.
This is why discourse is both a theoretical and practical concept. You notice it immediately in the edit. It's invisible in the screenplay, but your mise-en-scène makes it visible.
