{
    "prompt": "A cinematic automotive brand film shot at golden hour on an open mountain highway. Anamorphic widescreen, documentary realism, no CGI gloss.  Reference usage: the reference image locks the hero car's body shape, white paint and backlit key light; reference video 1 sets the approach speed and low camera height; reference video 2 sets the cornering rhythm; use the reference audio as the score throughout.  [00:00-00:06] Extreme wide aerial: a ribbon of asphalt threading through mountain ridges, low sun flaring past the peaks, a single white sports car entering frame far below. Ambience: wind, distant engine note. [00:06-00:12] Low tracking shot at wheel height as the car sweeps through a downhill corner, tyres biting, heat haze rippling off the surface, lens flare streaking across frame. Ambience: tyre hum, engine load rising. [00:12-00:19] Interior cutaway: driver's hands on the wheel, weathered leather, a quick glance to the mirror; warm sunset rakes across the dashboard. Shallow depth of field, 50mm feel. [00:19-00:25] The car accelerates straight toward a locked low camera, sun sitting just above the roofline, grille and headlights growing until they fill the frame; cut to black with clean centre space for an end card.  Style: cinematic automotive commercial, anamorphic flare, warm golden backlight against deep cool shadow, realistic paint reflections and tyre contact, subtle film grain. Camera: aerial, low tracking, interior handheld-stabilised, final locked approach. No whip pans, no speed ramps. Audio: layered engine and wind foley over the reference score, no voice-over. Avoid: warped or duplicated bodywork; wheels rotating backwards; floating car without tyre contact; text, subtitles, watermarks, brand logos; flicker or jump cuts.",
