Cinematic Motion Language

Cinematic Motion Language

Purpose

This skill provides the five-pillar language system for constructing video prompts with cinematic precision. 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:

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]

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.
