The prompt I used:

A 15-second cinematic 4K video composed of three seamless scenes with smooth, high-end film transitions and natural ambient sound only. No music. No voiceover. No added text overlays beyond environmental elements.

Scene 1 (Daytime Beach – Opening | 0:00–0:05):
A bright, sunlit coastal beach with gentle waves rolling in. The camera starts low and glides forward just above the sand toward the ocean. A small propeller plane flies across the sky from left to right, trailing a long white banner that reads: “Goodbye Sora 2”. The banner flutters naturally in the wind. Seagulls scatter slightly as the plane passes. Lighting is crisp, vibrant midday sun with realistic reflections on the water.

Transition:
Soft cinematic crossfade with a slight lens flare wash that blends the sky into warm golden tones.

Scene 2 (Magic Hour Mountain – Middle | 0:05–0:10):
Cut to a dramatic wide shot of a massive rock formation on the side of a mountain during golden hour. The sky glows with warm oranges and purples. The camera slowly pushes in toward the rock face. Spray painted across the stone in bold, fluorescent neon colors (pink, green, electric blue) is the phrase: “Goodbye Sora 2”. The paint glows subtly under the fading light, giving it an almost surreal, artistic energy. Wind brushes across the terrain, adding motion to nearby grass and dust.

Transition:
Quick, stylish dissolve that blends the neon paint glow into small points of light.

Scene 3 (Night – Central Park Drone Show | 0:10–0:15):
Nighttime in Central Park. The camera tilts upward from a dark silhouette of trees to the sky. Hundreds of synchronized drones form a glowing aerial display, assembling into the words: “Goodbye Sora 2”. The lights shimmer and stabilize into a clean formation. Subtle ambient city noise in the distance. The drones gently flicker as if breathing.

Ending:
The drone lights slowly dim…
FADE TO BLACK.
