Create a 20-second premium family-friendly 3D animated cinematic ASMR rooftop transformation video.

Create a 20-second premium family-friendly 3D animated cinematic ASMR rooftop transformation video. Use the init image as the fixed rooftop environment reference. Preserve the empty rooftop layout, concrete surface, skyline direction, overall spatial scale, city height, and rooftop perspective. The video should show a complete satisfying transformation: from an empty concrete rooftop above a big city, to a cozy rooftop cottage oasis, ending with a magical night reveal. Visual style: premium 3D animated feature film quality, warm magical storybook atmosphere, soft rounded character design, painterly textures, tactile materials, charming cinematic lighting, shallow depth of field, creamy bokeh, gentle motion blur, cozy ASMR construction rhythm, warm color palette, handcrafted details, family-friendly animation aesthetic. Main characters: A young animated couple in their mid-20s, warm, expressive, charming and cooperative. They have soft rounded 3D animated proportions. They are building their rooftop dream home together. Keep their faces, body proportions, clothing colors and personality consistent throughout the video. They should look focused, happy, gentle and purposeful, not posing for the camera. Overall story: The video begins with an extreme macro ASMR construction hook, then rapidly reveals the empty rooftop, then transitions into a satisfying construction timelapse, and finally ends with a glowing nighttime rooftop oasis reveal. Timeline and action progression: 0s-5s — ASMR HOOK: Start with an extreme macro close-up of a stylized 3D animated hand gripping a wooden hammer mid-swing. The hammer is about to strike a single shiny metal nail standing on a fresh wooden plank. Show detailed wood grain, tiny scratches on the nail, floating sawdust particles, golden morning sunlight, shallow depth of field and creamy bokeh. The hammer strikes the nail with a satisfying impact. Add subtle motion lines, tiny impact stars, sawdust burst, plank vibration and a small hammer-head bounce. The impact should feel crisp, tactile and satisfying, not violent or explosive. Immediately after the impact, the camera rapidly pulls back and rises in a dolly-zoom reveal. First reveal the wooden plank, then the young couple kneeling on the concrete rooftop working together, then the empty rooftop space, and finally the massive big-city skyscrapers under a golden morning sky. 5s-15s — BUILD-UP CONSTRUCTION TIMELAPSE: Transition into a cinematic ASMR rooftop construction timelapse. Begin with an aerial top-down shot descending toward the rooftop. Cut to a low-angle shot as the young couple enters carrying toolboxes, wooden planks and rolled blueprints. Show satisfying close-ups of hands hammering, measuring, brushing dust, tightening screws, placing beams and painting surfaces. Wooden beams snap upward into place. The cottage frame rises piece by piece. Cream-white walls slide and lock into position. Terracotta roof tiles spiral neatly into rows. Brush strokes smooth themselves into clean cream-white walls. Terracotta flower pots slide gently into place. Tropical plants grow subtly around the house. A small rooftop pool forms beside the cottage. End this section with an extreme close-up of crystal turquoise water cascading into the pool, slow-motion splash droplets catching warm sunset light. The lighting transitions from golden morning to warm daytime glow and then to orange-pink sunset. The city skyline remains visible in the background throughout. Construction motion should feel magical but physically grounded: wood beams rise as if guided by invisible timing, walls assemble with clean satisfying clicks, roof tiles rotate and settle naturally, plants unfurl softly, pool water fills with sparkling ripples. Keep the rhythm clean, cozy, smooth and ASMR satisfying. 15s-20s — NIGHT REVEAL: Transition from sunset into night. Reveal the completed cozy rooftop oasis. The rooftop now has a cream-white cottage with a warm terracotta roof, glowing amber windows, a small porch, a turquoise pool with underwater lights, lush tropical garden, palm trees, bougainvillea, terracotta pots, soft grass patches and warm fairy string lights. Palm fronds gently finish unfurling in the night breeze. Bougainvillea flowers softly pop open. Fairy lights ignite one by one in a warm amber sequence. The pool water shimmers with turquoise ripples. Warm window light flickers gently. The city skyline in the background glows with thousands of tiny bokeh windows. The young couple appears on a porch swing, hugging warmly and quietly. They look satisfied and peaceful after completing their rooftop dream home. Their movement should be subtle and emotional: a gentle lean, a soft embrace, tiny head movement and relaxed breathing. Camera for final reveal: start low, gliding across the glowing turquoise pool surface; pass reflections of fairy lights and warm windows; rise slowly past tropical leaves and the cottage porch; finish with a graceful aerial pull-back reveal from above, showing the complete rooftop oasis: glowing cottage, lit pool, tropical garden, fairy lights, and the vast illuminated city skyline far below. Camera style: cinematic but smooth, macro close-up, dolly-zoom pullback, aerial top-down descent, low-angle construction shots, tracking shots past painted walls, overhead garden formation, extreme close-up pool water splash, low pool-surface glide, final aerial pull-back reveal. Use clean readable motion and satisfying visual rhythm. Mood: cozy accomplishment, magical construction, romantic warmth, peaceful wonder, dream home completed above the city. The video should feel like a satisfying animated ASMR build from an empty rooftop into a beautiful glowing rooftop cottage oasis. Important restrictions: Do not add text, captions, subtitles, logos, watermarks, UI, arrows, labels, guide marks, construction diagrams, blueprint overlays, storyboard panels or frame borders. Do not add extra characters, crowds or workers. Do not show unsafe construction, injury, danger, realistic violence or scary darkness. Do not make the video look like a realistic architectural render, luxury advertisement, industrial documentary or chaotic construction site. Do not make the hammer impact violent or dangerous. Keep everything charming, clean, warm, magical, cozy, family-friendly and emotionally satisfying.
