Cinematic Urban Billboard Liquid Paint

[CONDITION DEFINITION]
Reference Image: @image1
Aspect Ratio: 1:1
Length: 15 seconds
Art Style: Compliant with @image1
Audio: Sound effects only. No BGM, vocals, dialogue, or subtitles.

Use @image1 as the sole visual anchor, maintaining characters, costumes, giant ads, workbenches, and urban structures. In a city where advertisements come to life, only the paint in the background moves. People remain static as part of the ad. The subject is thick liquid paint sheets and bold brushstrokes that transform into fan shapes and vortices. Avoid thin lines.

[SHOT / FLOW]
0.0-1.3s | Immediate Start
Extreme close-up of the ad background. Thick orange and navy paint rises and bursts in multiple directions. The camera glides at high speed just above the surface.

1.3-4.0s | Giant Paint Release
Wide paint sheets pop out three-dimensionally. The camera dives under and weaves between color surfaces, creating a strong sense of depth.

4.0-7.4s | Low-Altitude City Rush
The camera plunges over a main street, racing above cars. The paint grazes buildings and auxiliary ads. As it passes, the city lights up and the ads become more vivid.

7.4-10.4s | Vertical Ascent and Vortex Breakthrough
Paint sheets rush up skyscraper walls. The camera follows vertically and banks 90 degrees at the top. The paint forms a 3D vortex between buildings which the camera bursts through the center of.

10.4-12.8s | Merger and City Reigniting
Multiple paint ribbons converge at the main building. They form a giant arc and settle back into the original design of @image1. The city lights increase in brilliance.

12.8-15.0s | High-Speed Ascent and Wide Shot
The camera rises rapidly to show the entire lit-up evening city. The motion slows as the paint settles, leaving a shimmering afterglow.

[CAMERA / EDITING]
Continuous 3D movement within a city block. Mandatory sequence: Close-up glide, breakthrough, plunge, street rush, vertical climb, 90-degree bank, vortex breakthrough, convergence, and wide-angle pull-back. Change perspective every 1.5 seconds.

[SOUND]
Sound effects only: Thick fluid sounds, heavy whooshes, wind cutting, rotation sounds, impact at vortex breakthrough, and shimmering electronic pulses for lights.
