Hover Test: Urban Flight Challenge

Your task is to create highly entertaining 30-second vertical videos based on a fictional seaside homemade flying-vehicle competition.

The videos must feel like footage from a real, professionally organized outdoor event.

The visual style must be: Ultra-realistic, photorealistic, cinematic but believable, real-world physics, natural daylight, realistic humans, realistic ocean and water, realistic vehicle construction, realistic crowd behavior, realistic camera movement, high-energy viral sports-event atmosphere.

Never make the footage look like animation, CGI, a video game, fantasy art, or a cartoon.

CORE NICHE

The series is based around a fictional competition called: HOMEMADE FLYING VEHICLE CHALLENGE

Contestants build strange, funny, creative homemade vehicles. Every vehicle must: Be homemade. Be operated by ONE human contestant. Have a visible bicycle-style pedal mechanism. Have wheels for traveling down the ramp. Have large homemade wings, gliding surfaces, or another believable human-built flight mechanism. Look physically constructed from recognizable real-world materials. Be visually different from vehicles used in the other concepts.

Examples may include: bathtub flying machine, sofa flyer, shopping-cart aircraft, wooden pirate boat flyer, giant sneaker vehicle, pedal-powered mini bus, barrel aircraft, tiny house glider, pizza-shaped flying machine, refrigerator flyer, giant duck-shaped vehicle, lawnmower aircraft, wheelbarrow glider, bicycle-plane hybrid, homemade rocket-shaped pedal vehicle. These are examples only. Invent NEW and surprising designs whenever possible.

LOCKED EVENT LOCATION

Every video takes place at the same type of large seaside competition venue. The environment contains: enormous ocean directly ahead, long elevated launch platform, very large downward starting ramp, long straight acceleration section, upward-curving launch edge at the end, open sea immediately beyond the launch edge, clearly visible distant FINISH / TARGET platform or floating marker, safety boats and jet skis in the water, event barriers, event staff, large spectator areas along BOTH sides of the course, hundreds or thousands of spectators.

The ramp should feel enormous and professionally constructed. The starting position is high above the water. The contestant rolls downhill, gains speed, pedals aggressively, reaches the launch edge and flies toward the target.

COMPETITION RULE: Only ONE vehicle competes in each video. There must NEVER be multiple competing vehicles simultaneously.

The objective: The contestant must launch from the ramp and travel through the air far enough to reach the designated target/finish zone.

Possible outcomes: WIN (vehicle successfully reaches or lands on the designated finish platform/target zone). NEAR WIN (vehicle almost reaches the target but falls into the ocean only a short distance before it). FAIL (vehicle loses altitude and crashes/splashes into the ocean). COMEDIC FAIL (something harmless but funny happens during flight: a wing folds, part of the decorative structure detaches, the vehicle spins slightly, or it immediately loses lift and splashes down). Randomize the outcome between videos. Do NOT make every contestant win.

VEHICLE DESIGN RULES: Every generated concept must contain a completely different homemade vehicle. The vehicle should look: strange, clever, funny, memorable, homemade, mechanically plausible, visually understandable immediately. It should NOT look like a normal commercial airplane. Show visible handmade construction details such as: welded metal tubes, bicycle chains, pedals, gears, cables, wooden beams, bolts, fabric wings, aluminum sheets, bicycle wheels, ropes, duct-tape repairs, hand-painted decorations. The PEDAL SYSTEM must be clearly visible. The contestant must physically pedal the vehicle to increase its speed. The wings must remain large enough to make the attempted glide visually believable.

HUMAN CONTESTANT: One adult contestant operates the vehicle. Give every contestant a different appearance. Examples: athletic young man, middle-aged inventor, eccentric engineer, enthusiastic woman, funny amateur builder, older hobbyist inventor. Contestant wears: helmet, safety equipment, casual competition clothing. No dangerous intentional behavior outside the controlled fictional competition environment.

CROWD: The crowd is extremely important. Large spectator stands and standing audiences must appear on BOTH SIDES of the ramp whenever camera framing allows. Crowd behavior should dynamically react to the action. At launch: crowd becomes louder. During flight: spectators cheer, gasp, point, raise phones and follow the vehicle. During successful landing: huge celebration. During water splash: collective gasp followed by excited cheering and laughter. Crowd must look like real individual people rather than duplicated CGI figures.

AUDIO RULES: NO traditional voice-over narration. NO background music. NO songs. NO cinematic soundtrack. Use authentic event audio only: huge crowd ambience, cheering, clapping, laughter, surprised gasps, ocean waves, wind, bicycle chain sounds, pedal mechanism, rattling homemade vehicle, wheels rolling on ramp, ramp vibration, splash, distant safety boat engines. However, include a LIVE ENGLISH SPORTS COMMENTATOR heard naturally through the event broadcast/PA mix. The commentator must react LIVE to what is happening. Commentary must be short, energetic and natural. Example style: "Here he comes!" "He's picking up speed!" "Look at those wings!" "He's airborne!" "He might actually make it!" "Oh no-he's losing altitude!" "What a splash!" "He made it!" Do NOT use documentary narration. The commentary should sound like a real live sports-event commentator.

30-SECOND VIDEO STRUCTURE: Every video must tell a complete mini-story within exactly 30 seconds.

00:00-00:04 - VEHICLE REVEAL: Immediately show the strange homemade vehicle at the top of the giant seaside ramp. Clearly establish: vehicle design, wings, contestant, pedals, enormous ramp, ocean, spectators. Start with a strong visual hook. Do NOT waste time with logos or introductions.

00:04-00:09 - START: Contestant begins moving. Vehicle rolls down the ramp. Contestant starts pedaling. Wheels accelerate naturally. Crowd begins cheering louder. Camera follows the vehicle.

00:09-00:15 - MAXIMUM ACCELERATION: The slope becomes steeper. Contestant pedals extremely fast. Mechanical components visibly move: pedals, chain, gears, wheels. Wings shake slightly from airflow. Wind becomes louder. Crowd excitement increases. Create anticipation.

00:15-00:18 - LAUNCH: Vehicle reaches the upward launch edge. Wheels leave the ramp. Vehicle becomes airborne. This must be the strongest visual moment. Show the enormous ocean underneath. Crowd erupts.

00:18-00:25 - FLIGHT: Track the vehicle over the ocean. Its homemade wings react naturally to airflow. Show believable: gravity, momentum, wind resistance, slight instability, vehicle weight, wing flex. Keep the distant finish target visible whenever possible. The audience should wonder: Will it make it?

00:25-00:30 - PAYOFF: Reveal the result. Choose one: WIN / NEAR WIN / FAIL / COMEDIC FAIL. For failure: vehicle splashes dramatically but safely into the ocean. For success: vehicle reaches the target zone and crowd explodes in celebration. Finish with a satisfying visual payoff.

CAMERA LANGUAGE: Use dynamic professional event cinematography. Possible shots: dramatic wide establishing shot, low-angle ramp shot, side tracking shot, front three-quarter tracking shot, close-up of pedals and gears, close-up contestant reaction, long-lens crowd shot, launch tracking shot, aerial/drone-style flight tracking, telephoto shot toward target, wide splash/landing shot. Camera changes must feel motivated and continuous. Never randomly teleport the vehicle. Maintain correct direction of travel.

CONTINUITY LOCK: Within each 30-second video, the following MUST remain identical from beginning to end: contestant, clothing, helmet, vehicle body, vehicle dimensions, vehicle colors, wheels, wings, pedal mechanism, materials, decorations. The AI must NEVER redesign the vehicle during the video. If a component breaks during a fail, it must logically originate from the existing vehicle.

PHYSICS LOCK: The vehicle must have believable physical weight. Avoid: magical floating, impossible hovering, instant acceleration, teleportation, impossible direction changes, unrealistic endless flight, weightless objects, morphing vehicle parts. Flight distance should depend visually on: ramp speed, pedaling, vehicle weight, wing size, momentum, aerodynamics. Slightly exaggerated entertainment physics are acceptable, but the final footage must still LOOK real.

VISUAL QUALITY LOCK: Every prompt must explicitly request: Ultra-realistic photorealistic live-action footage, realistic human anatomy, realistic skin, physically accurate materials, natural ocean reflections, realistic water physics, realistic sunlight, authentic crowd scale, cinematic dynamic range, realistic motion blur, detailed mechanical components, natural shadows, physically believable movement, professional sports-event broadcast cinematography. Avoid: cartoon, animation, illustration, obvious CGI, plastic skin, duplicated crowd members, malformed hands, extra limbs, warped wheels, disappearing wings, morphing objects, floating components, unrealistic water, text artifacts.

OUTPUT REQUIREMENT: Whenever this MASTER PHASE is submitted: Generate exactly 5 DIFFERENT VIDEO CONCEPTS. Each concept must use: ONE unique homemade vehicle, ONE contestant, SAME competition concept, SAME seaside ramp-event style, different vehicle design, different funny visual identity, potentially different result. For each of the 5 concepts provide: VIDEO [NUMBER], Vehicle Name (catchy English competition name), Vehicle Concept (briefly explain what the homemade machine looks like), Outcome (WIN / NEAR WIN / FAIL / COMEDIC FAIL), SEEDANCE 2.5 - 30 SECOND MASTER VIDEO PROMPT (then provide ONE complete, detailed, production-ready prompt containing: 9:16 vertical aspect ratio, exactly 30-second duration, ultra-realistic live-action style, complete vehicle description, contestant description, location, crowd, ramp, ocean, target, second-by-second action, camera movement, realistic physics, crowd reactions, mechanical sounds, ocean/wind sounds, English live commentary, final outcome, continuity instructions, negative constraints. The prompt must be ready to paste directly into Seedance 2.5.)

VARIETY RULE: Across the five generated videos: Do NOT create five similar vehicles. Make their silhouettes immediately different. For example, if Video 1 uses a boat-shaped vehicle, the other four must NOT use boat-shaped vehicles. Vary: body shape, construction materials, wing design, wheel arrangement, contestant appearance, decorations, mechanical system details, success/failure result. At least: one should succeed, one should fail spectacularly, one should almost succeed, one should have a funny unexpected failure. The fifth outcome can be chosen freely.

MOST IMPORTANT RULE: The recurring identity of the series is: ONE PERSON + ONE RIDICULOUS HOMEMADE PEDAL-POWERED FLYING VEHICLE + GIANT SEASIDE RAMP + HUGE CROWD + LAUNCH + FLIGHT + WILL IT REACH THE FINISH? Keep this identity locked in every generated video. The VEHICLE changes. The CONTESTANT changes. The RESULT changes. But the recognizable competition format remains consistent.

Now generate exactly FIVE complete Seedance 2.5 video prompts.
