Dynamic Overhead Flow: Elegant Product Reveal

{
  "shot": {
    "type": "single",
    "shot_size": "overhead medium-wide easing to medium",
    "camera_motion": "One continuous overhead dolly-arc: slow push-in while orbiting clockwise ~20°; no other moves.",
    "lens": "50mm equivalent",
    "aperture": "f/4",
    "shutter": "1/48",
    "iso": 200,
    "filters": "Circular polarizer at 50% to balance glare and subsurface visibility",
    "notes": "Naturalistic exposure; highlight rolloff on specular ripples."
  },
  "subject": "Two adult koi (Nishikigoi), metallic rose-red scales with subtle magenta iridescence, pale-gold fins and tail, 35–40 cm length, healthy and graceful.",
  "scene": "Outdoor koi pond in open shade; deep indigo water from sky reflection and dark liner. Sakura petals scattered on the surface; two closed lotus buds near opposite corners; dark stone bottom faintly visible in calm patches.",
  "visual_details": [
    {
      "t": "0.0–2.5s",
      "beat": "Approach. Petals drift; ripples travel gently. The two koi glide in from opposite edges on complementary arcs, establishing a clockwise rotation. Fin strokes create soft V-wakes that begin to steer nearby petals."
    },
    {
      "t": "2.5–5.5s",
      "beat": "Cinematic dance: a slow synchronized figure-eight (lemniscate). They counter-rotate through center with a near-miss cross, then open the loop—one koi rolls slightly toward camera showing scale iridescence; the other dips, revealing faint stone below through refracted water. Petals are advected by their vortices and spin realistically."
    },
    {
      "t": "5.5–8.0s",
      "beat": "Resolve. They curve into a yin-yang mirror, tails flick in opposite directions, noses pass gently. A single petal kisses one snout and pirouettes, generating tight concentric ripples. Camera completes the push-in and holds on the symmetrical tableau for the final half-second."
    }
  ],
  "cinematography": {
    "lighting": "Open shade skylight; moving speculars from ripple geometry; no stylized glow.",
    "focus": "AF priority on the nearer koi; medium DOF keeps both readable while stones/petals at distance soften. Surface refraction and distortion physically correct.",
    "grade": "Photoreal, neutral filmic contrast; restrained saturation; preserved microtexture on scales and petal veins."
  },
  "audio": {
    "music": "Sparse, cinematic underscore: soft taiko/hand-drum pulse at 60–70 BPM with airy shakuhachi/bamboo-flute breaths—subtle, non-intrusive.",
    "fx": [
      "Pond ambience: gentle lapping and small water movement",
      "Koi foley: faint fin swishes and micro-bubble release during turns",
      "Petal contact 'plip' timed to the center pass at ~6.5s"
    ],
    "mix": "Integrated loudness ≈ −20 LUFS, peaks ≤ −6 dBFS; score low in the bed (−26 to −24 LUFS) so natural water remains primary; roll off highs above 12 kHz to avoid harshness; light garden slap-back reverb (<0.3s).",
    "dialogue": "none"
  },
  "color_palette": {
    "water": "deep navy/indigo",
    "koi_scales": "rose-red with magenta iridescence",
    "fins": "pale gold",
    "blossoms": "soft sakura pink",
    "accents": "neutral stone gray"
  },
  "physics_rules": [
    "Petals float with surface tension; each shows a slight meniscus and micro-shadow on water.",
    "Koi tail and pectoral beats generate vortices that advect petals and shear ripples realistically.",
    "Ripple propagation speed and amplitude decay follow physical damping; concentric rings attenuate naturally.",
    "Fresnel reflections vary with view angle; partial polarization reduces but does not eliminate glare.",
    "Motion blur governed by 1/48 shutter: fin tips show light blur, bodies remain crisp."
  ],
  "visual_rules": [
    "Strict photorealism—no illustration outlines or toon shading.",
    "Only the two koi described; accurate Nishikigoi anatomy and scale tiling.",
    "Organic petal/lotus detail with mild imperfections; avoid plastic look.",
    "No text, subtitles, logos, watermarks.
