@Image 1: Elena Vance, corporate executive, charcoal wool suit, silver hair pin.
@Image 2: Marcus Wright, tech founder, navy unbuttoned blazer, white collared shirt.
One-sentence summary: Elena confronts Marcus in a rain-streaked high-rise office over leaked board minutes, shot in wide-angle lighting.
0-4s: Wide establishing shot. Rain streaks the floor-to-ceiling glass windows overlooking a dark city skyline. Elena walks across the hardwood floor toward Marcus, holding a physical dossier.
4-8s: Medium two-shot. Elena places the folder firmly onto the mahogany desk. Marcus leans forward, looking directly into her eyes without touching the documents. Elena says: "The board convenes at dawn, Marcus. Sign it or step down."
8-12s: Close-up on Marcus. He lowers his gaze to the papers, pauses, and exhales slowly. Ambient thunder rumbles softly outside as ceiling recessed lights hum.
Consistency notes: Keep lighting moody with cold blue window backlights and warm desk lamp accents. Lock facial features to @Image 1 and @Image 2 throughout.

@Image 1: Julian, undercover courier, dark green hooded field jacket, messenger bag.
@Image 2: Handler Chen, sharp trench coat, umbrella, dark leather gloves.
One-sentence summary: Julian evades Handler Chen across a crowded tiled subway platform during the evening commute, captured in handheld tracking shots.
0-5s: Tracking shot behind Julian as he briskly navigates through commuters on the platform. Fluorescent platform lights flicker overhead while public address announcements echo.
5-10s: Over-the-shoulder shot from Chen's perspective as Chen spots Julian through the crowd and quickens pace. Julian glances back, notices the pursuit, and darts toward the departing train doors.
10-15s: Low-angle tracking shot. Julian slips sideways through the closing subway doors just as Chen reaches the yellow safety line. The train accelerates with metallic rail screeching.
Consistency notes: Maintain handheld camera motion with natural optical shake. Match subway car interior colors to cool industrial green.

@Image 1: Titanium luxury chronograph watch with matte black dial and orange second hand.
One-sentence summary: Commercial product reveal of a titanium chronograph emerging from dark water droplets, captured with macro lens lighting.
0-3s: Macro extreme close-up. Water droplets bead and glide across the sapphire crystal face. The orange second hand sweeps smoothly across mechanical dial markers.
3-6s: Dynamic orbital camera move around the titanium bezel. Studio edge lights highlight the brushed metal chamfers against a seamless black backdrop.
6-10s: Slow pull-back to a three-quarter hero shot. The complete watch hovers suspended as subtle mist swirls around the wrist strap. Clean studio lighting reflections only.
Consistency notes: Maintain product geometry identical to @Image 1. No background music; generate mechanical ticking and crisp water foley.

@Image 1: Mountaineer in an alpine orange technical shell jacket with storm hood.
One-sentence summary: Field demonstration of a waterproof jacket enduring a sudden mountain rainstorm, shot in documentary realism.
0-3s: Tight shot of water sheets impacting the jacket shoulder fabric and instantly rolling off without absorption. Wind roars softly in the sound mix.
3-6s: Medium profile shot. The mountaineer raises the storm hood and cinches the elastic drawcord with gloved hands, looking up toward a snow-capped ridge.
6-8s: Wide heroic shot. The hiker steps forward onto a rocky plateau under overcast storm clouds. Natural outdoor daylight with mist dispersion.
Consistency notes: Lock jacket color and logo placement to @Image 1 across all angles. Generate realistic wind and fabric rustle audio.

@Image 1: Solo female dancer, reflective silver crop jacket, black cargo trousers.
One-sentence summary: A beat-synced solo dance performance in a wet asphalt alley illuminated by magenta and teal neon signs, shot in smooth gimbal arcs.
0-4s: Low-angle wide shot. The dancer stands centered in the alley. On the opening bass drum drop, she executes an isolated shoulder pop and spins on her heel.
4-8s: Medium tracking shot circling the dancer clockwise. Puddle reflections kick up water droplets as she performs rhythmic footwork in sync with the beat.
8-12s: Slow-motion frontal push-in as she turns toward the lens, hits a locked freeze pose, and exhales visible condensation into the night air.
12-16s: Rapid pull-back to wide shot revealing alley brick walls, fire escapes, and neon signs reflected in standing water.
Consistency notes: Keep wardrobe identical to @Image 1. Maintain wet pavement reflections and rich magenta side-fill lighting.
