MOTION
LOGIC

The visual syntax of motion, scale, and continuity in AI video generation.

Built to prevent isolation errors, spatial collapse, and fake physics.

01. Core Syntax

// BASIC_AXIS
Pan and Tilt Diagram

Pan & Tilt (Static Axis)

Camera rotates on a tripod. No physical translation.

PAN Horizontal Scan
TILT Vertical Reveal
Dolly and Truck Diagram

Dolly & Truck (Physical)

Camera moves through space. Parallax engaged.

DOLLY In / Out (Depth)
TRUCK Left / Right (Lateral)

02. Vehicular & Structural

// RIGID_BODY_PHYSICS
FPV Diagram

FPV Flow

AERIAL

High speed banking and rolling. Simulates flight physics.

FIRST PERSON VIEW Aggressive movement relative to landscape/geometry.
$ FPV drone dives vertically down glass skyscraper
Crane Diagram

Structural Orbit

CRANE

Camera moves relative to massive rigid structures.

MASSIVE SCALE Orbiting buildings or cliffs while maintaining volume.
$ Wide crane shot rising up the side of a brutalist structure

03. Figure & Action

// BIO_MECHANICAL_FLOW
Body Mount

Body-Relative Lock

Camera is physically attached to the subject.

SNORRICAM Face static, background shakes violently.
POV (First Person) Seeing through the character's eyes. Hands/arms visible.
Action Track

Dynamic Action Tracking

Following bio-mechanical movement (Running, Combat).

MATCH SPEED TRACKING Camera matches runner's velocity. Speed lines.
WHIP PAN Fast rotation to follow a punch or turn.

04. Continuity Logic

// IDENTITY_LOCK

Identity Anchoring

Action Track
THE RULES Neutral lighting, zero distortion, clear facial structure. No filters or "vibe" words.
$ Anchor Reference: Neutral lighting, straight-on angle, factual description only

Triangulation (Identity Kit)

Action Track
  • 1. Anchor: Neutral Front-Facing.
  • 2. Profile: Side view to define nose/jaw structure.
  • 3. Expression: Extreme emotion (e.g., shouting) to test elasticity.

Anatomical Grounding

Action Track
SCALE REFERENCES Upload Half-body (for neck/shoulders) and Full-body (for silhouette/posture).
$ Input: Close-up (Face Geometry) + Full Body (Limb Proportions) = Stable Identity

The "Fixed Identity" Command

Action Track
PROMPT LOGIC Force the model to treat the uploaded reference as absolute truth.
$ "Use this person as the identity reference. Do not alter face geometry, skin texture, or bone structure."

05. Failure Prevention

// DEBUG_MODE

AI video models default to subject isolation unless parallel motion and intent are explicitly defined.

Physical Safeguards

  • Volume Preservation: Buildings must not flatten or warp during camera orbits.
  • Wheel Rotation: Maintain physics-based rotation during drifts.

Environmental Anchors

  • Static Backgrounds: Distant mountains must not drift.
  • Parallax Layers: Foreground blurs faster than background to maintain scale.

06. Optical Texture

// LENS_PHYSICS

Anamorphic

Wide cinematic compression, oval bokeh, horizontal flares.

Fisheye

Extreme wide-angle distortion for speed, unease, or proximity.

Telephoto / Macro

Compressed space, shallow depth of field, isolated details.

Tilt-Shift

Selective focus band. Makes cities look like miniature models.

VHS / Glitch

Analog artifacts, chromatic aberration, tracking errors.

Deep Bokeh

Creamy background blur to separate subject from chaotic environments.

07. Temporal Logic

// TIME_MANIPULATION

Speed Ramping

Changing the speed of footage dynamically within a single shot.

$ Action starts in slow motion (high frame rate) then suddenly ramps to normal speed upon impact

Bullet Time (Frozen)

Camera moves through space while time is frozen for the subject.

$ Camera orbits around the frozen explosion, debris suspended in mid-air, 360 degree pan

Time-Lapse / Hyperlapse

Compressing long durations into seconds. Clouds, traffic, or decay.

$ Hyperlapse moving through busy Tokyo street at night, light trails from cars, crowds blurring

Reverse / Rewind

Reversing entropy. Shattered objects reassembling, smoke returning to source.

$ Shattered glass lifts off the floor and reassembles into a perfect vase on the table
