Apply it to any video generation task — atmosphere shots, product reveals, character scenes, abstract motion, sacred/spiritual visuals, or any brief where imprecise language would produce unpredictable results. The core principle: the model understands physics, geometry, sequence, and constraint — not adjectives. Replace every vague descriptor with a physical analogy, spatial coordinate, temporal sequence, or hard rule. ## The Five Pillars - 1. Camera Contract State the camera's behavior as a hard rule before describing anything else. The model treats the camera as a character — define it or it will improvise. Examples: - "Static locked-off camera. Zero movement. No pan, no zoom, no dolly, no shake." - "Slow push-in only — 10% scale change over the full duration." - "Single handheld drift, slight organic sway, no cuts." - Always reinforce camera rules in the negative prompt as well. ## 2. Motion Physics Anchor Give every moving element a speed reference from the physical world, not an adjective. Pair physical analogies with time-anchored measurements for maximum precision. Speed analogy examples: - "like dust suspended in honey" - "like embers floating in still air" - "like smoke through a cathedral at dawn" - "like the surface of a lake disturbed by a single drop" Time-anchored measurements: - "one full revolution across the entire 10-second clip" - "roughly 6 degrees per second" - "the pace of a clock's hour hand — imperceptibly slow" - "travels the full arc in 8 seconds with no pause" - Never use "slow", "fast", "gentle", "subtle" alone — always anchor to physics or time. ## 3. Spatial Zoning Divide the frame into named regions and assign explicit rules to each. This prevents the model from filling empty space with invented content. Region naming conventions: - "Left third / center third / right third" - "Foreground plane / midground / background" - "Upper half / lower half" - "Right two-thirds / left void" Example zone rules: - "Left third: pure black, no light, no particles, no movement." - "Right two-thirds: all action contained here." - "Foreground plane: particle layer only — no subject." - "Background: unlit void, no detail." - Always cross-reference spatial zones in the negative prompt. ## 4. Lens Behavior Sequence Describe focus and depth of field as a narrative event with a beginning, middle, and end. Models can simulate focus-breathing, rack focus, and lens diffusion — but only when the sequence is described explicitly as cause and effect. ## Structure: trigger → shift → state → return → repeat Example: "Focus opens on the subject. As the foreground element crosses the lens plane, focus shifts onto it — the subject softens into warm bokeh. The element drifts past. Focus breathes back to the subject. This cycle repeats organically 2-3 times." Key lens vocabulary: - "shallow depth of field" - "focus-breathing" — organic in/out shift - "rack focus" — deliberate, directional shift between two subjects - "bokeh silhouette" — subject dissolves into soft out-of-focus warmth - "lens plane crossing" — the moment a foreground element passes between camera and subject - "anamorphic lens rendering" — oval bokeh, horizontal flare character, widescreen feel ## 5. Negative Space as Compositional Tool Name empty areas of the frame as intentional design decisions, not absences. Then reinforce them in the negative prompt. Examples: - "Sacred emptiness — the left third is a deliberate compositional weight." - "No light bleed into the dark half." - "The darkness is active, not background." - "Void occupies the left two-thirds — no fill, no ambient spill, no movement." Negative prompt reinforcement: - "particles on the left side, light on the left side, movement on the left side" ## The Prompt Template Use this structure for every high-precision video brief: CAMERA: [static / push / drift / handheld — state as a hard rule] ASPECT RATIO: [21:9 / 16:9 / 9:16] DURATION: [X seconds] ## Style & Mood: [visual register + atmosphere in one line] Narrative: [one sentence — what happens] Action: - Subject: [who/what, position in frame, emotional state] - Motion: [speed anchor — physical analogy + time measurement] - Secondary motion: [particles / fabric / smoke — own speed anchor] Lens: - Focal feel: [wide / normal / telephoto character] - Focus event: [cause → shift → state → return → repeat count] - DoF: [shallow / deep / breathing] ## Lighting: [source count, direction, quality, color temperature] Spatial Zones: - [region]: [rule] - [region]: [rule] - [region]: [rule] Audio: [sound texture description — not music genre] ## Quality suffixes: [photoreal, film grain, anamorphic, 8K detail, etc.] Negative Prompt: [camera moves, spatial violations, style rejections, motion violations] ## Key Vocabulary Reference Camera static locked-off / handheld drift / slow push-in / crane reveal / whip pan / zero movement / no reframe / locked composition ## Motion Speed suspended in honey / floating in still air / cathedral smoke / hour-hand pace / imperceptibly slow / continuous fluid arc / no acceleration / no stillness ## Particle Behavior three-dimensional spiral / orbiting / foreground crossing / contained within zone / rising and descending in soft arcs / catching directional light / swirling behind and around ## Lens / Focus shallow depth of field / focus-breathing / rack focus / bokeh silhouette / lens plane crossing / anamorphic rendering / focus returns organically / sharp foreground — soft midground — void background ## Lighting single key light / directional warm / chiaroscuro / golden-amber / deep shadow / no fill / no ambient spill / upper right source / rim light / backlight halo ## Negative Space sacred emptiness / pure black void / no light bleed / no particles / no movement / deliberate compositional weight / active darkness ## Advanced Techniques references/implied-off-screen-motion.md: How to choreograph limbs/props moving through a locked frame to imply a body rotating or moving outside the camera's view. Worked Example — Dervish Shot Brief: Whirling dervish, close-up of raised hand and forearm, golden dust particles, pure black left third, sacred Sufi atmosphere. Camera: Static locked-off. Zero movement. No pan, no zoom, no dolly. Motion anchor: Hand traces the arc of one full Sama rotation over 10 seconds — the pace of a clock's hour hand. Particles move like embers in still air. Lens event: Foreground particles cross lens plane → focus shifts to particles (sharp, glowing) → hand softens to warm bokeh → particles drift past → focus returns to hand. Cycle repeats 2-3 times organically. Spatial zones: - Left third: pure black, no particles, no light, no movement. - Right two-thirds: all motion contained here. - Foreground plane: particle layer, passes in front of hand. - Lighting: Single warm key from upper right. Deep chiaroscuro. Golden-amber on black. Negative prompt: camera movement, pan, zoom, dolly, shake, fast motion, fast particles, particles on the left side, light on the left side, acceleration, abrupt cuts, cartoon, anime, strobing.
