Spec: a 20-second sci-fi action comedy in a cinematic look, shot as photorealistic live-action with CGI, in vertical 9:16 framing. Blockbuster-scale spectacle, bookended by a dry, deadpan joke at the start and another at the finish. Story: the supplied subject sits stuck in a post-apocalyptic gridlock and is fed up. One offhand tap on a dashboard button sends the car airborne and folds it into a giant mech. Winged monsters swoop in to shove it back down to the road. The subject pilots the mech, beats both of them, touches down, reverts into the very same car and drives off. === SUBJECT AND COCKPIT === The driver is the subject from the user's reference upload. Keep its identity, face, hair or fur, outfit and natural body structure, whether human or animal, exactly as supplied. Seat, harness and controls are sized to suit that body, and hands or paws work the relevant controls in a believable way. The very first frame must show the subject's face and its steering motion at once. From driving through flight, transformation and fighting, one and the same subject stays seated in one and the same cockpit. That undamaged cockpit turns into a capsule in the mech's upper chest, with a clear canopy so the pilot can always be seen. During the ambush and the counterattack, cut briefly into the cockpit and make the pilot's control movements agree with what the mech does outside. When the mech changes back, this capsule slides back to its original spot inside the car. === WORLD AND VEHICLE === Setting: a wide boulevard in a ruined, end-of-the-world city. Traffic stands still as far as the eye can see, with deserted buses, battered buildings, fires burning in the distance and ash floating in the air. Long lines of cars fill every lane. Beyond the blockage, make sure a clear open stretch of road exists, because the ending needs it. Vehicle: copy the silver supercar in the reference image. Angular silver bodywork, a black panoramic roof, black wheels, slim white headlights, a red light bar across the rear, four round thrusters, a black diffuser and a sharp-edged spoiler. The mech is built from the same silver and black parts. Sections of the chassis make its spine and pelvis, the rear assemblies turn into legs and the front assemblies into arms. Wheels come to rest by the shoulders and calves, bonnet plates surround the cockpit and the spoiler becomes stabilizers across the back. Every part must stay recognizably the same piece through both transformations. === MONSTERS === There are exactly two flying mechanical monsters, circling over the stalled cars. A: a heavy, armored hunter with turbine-style wings, huge clawed front limbs and a jaw shaped like an engine block. B: a long, black, segmented snake with red eyes and a weighty pincer on its tail. Their job is to push the escaping vehicle back down into the jam. Show them striking downward on purpose, making real physical contact, and the pilot straining against the pressure. === 0–4s | APOCALYPTIC TRAFFIC FRUSTRATION === OPENING SHOT: inside the car, a medium close-up from the front at a three-quarter angle, with the subject at the wheel and its face and working limbs plainly visible. Through the windshield behind it, brake lights sit unmoving. Car horns blare over each other outside. The subject tries to roll forward, but the car creeps just a few centimeters and halts. It glances ahead, then over to the neighboring lane, which is jammed just as badly. Its shoulders drop and it sinks back into the seat, tired and annoyed. For a moment, show how enormous the queue is through the windshield, stretching on between wrecked buildings. Next to the steering control, the subject spots a small lit button. Bored and impatient, it taps the button one time, like someone testing an unfamiliar dashboard feature. === 4–6s | UNEXPECTED ESCAPE === Dashboard lights flare up. The subject looks startled as all four thrusters abruptly fire. Cut to the exterior: a burst of dust shoots out between the parked cars around it. Straight up from the jam climbs the silver supercar, scraping past the neighbors' roofs, and then it speeds off above the boulevard. A short cockpit shot: the subject peers down at the traffic below, then grips the controls as its shock turns to thrill. The stuck road stays in view underneath. === 6–8s | RAPID TRANSFORMATION === That one tap has kicked off an automatic sequence of flight and transformation. While the car keeps climbing, silver panels release and swing open around the cabin, which stays whole and occupied. The chassis tips upright. The legs stretch downward as the shoulders and arms swing outward at the same moment. Wheels clamp into position, the feet unfold and the head lifts. Chest armor closes around the clear cockpit. The transformation must be entirely done at the 8-second mark, accompanied by a quick run of heavy mechanical clunks. The subject keeps sitting inside, plainly working the controls. === 8–11s | AERIAL AMBUSH AND NEAR DEFEAT === Use the monster designs already set up, with the same pilot inside the see-through chest cockpit. Monster A plunges from above and hammers both claws onto the mech's shoulders. The hit throws the mech sideways and pushes it down between the buildings. Monster B wraps itself around the mech's lower legs and hauls the other way, wrenching the body hard. Make the strain physical: shoulder joints crush together, armor grinds and sparks spray. The mech's thrusters labor against the pull of both enemies. The camera tracks alongside the drop, with building facades flashing upward behind the fighters. Short cockpit insert: the very same subject from the upload braces against its harness, face in clear view, then jams the controls forward with force. The control motion should suit human hands or animal paws naturally. === 11–14s | BREAK FREE AND BOOSTED FINISHER === The mech pulls one knee up to its chest, kicks clear of the serpent's coils and lights its back thrusters. Ducking one shoulder beneath Monster A's claw, it grabs the striking forelimb and drags the creature in close. It lands a vicious, tight elbow into the jaw casing, whipping the head to one side. With no pause, it follows with a single massive thruster-boosted straight punch into the monster's central engine. Show the whole motion: the torso coils back, the thrusters ignite, the fist lands, the armor collapses inward and the monster flies backward. Hold the impact for a fraction of a second, then return to full speed. Follow the crippled monster as it smashes through an empty machinery tower on a rooftop. Metal shards and dust burst outward, and its lights die. The mech stays in the foreground, already turning to face the serpent. === 14–16.5s | SECOND ATTACK AND ROTATIONAL FINISHER === The serpent lashes its pincer tail at the chest canopy. The mech twists aside by a hair; the tip grazes the shoulder armor and showers sparks right beside the glass. Both of the mech's hands seize the tail. A quick cockpit insert shows the pilot hauling and turning the controls. Cut straight to the mech blasting its side thrusters and spinning through one forceful full-body turn. The whole serpent is swung around in a wide arc, its segments stretched tight by the momentum. It lets go right toward the wrecked rooftop where Monster A lies out of action. Show the flight continuing into a crushing impact. The serpent's chassis folds and its red eyes go dark. Both enemies are clearly beaten as the mech boosts upward and passes over the debris. === 16.5–18.5s | REVERSE TRANSFORMATION IN MIDAIR === The mech stays aloft above the rooftops. Its thrusters give steady lift while it tilts smoothly forward into level flight. The occupied cockpit stays whole. Arms draw in beside it, legs fold under the chassis and wheels turn back to their starting spots. Silver bonnet and body panels glide together around the cabin. The spoiler locks on again and the four thrusters line up at the back. Show the full mechanical change back into the exact silver supercar from the start, all while it is still flying. By the 18.5-second mark the car must be level, nose pointed at the open skyline. === 18.5–20s | VICTORIOUS FLY-AWAY === Short interior shot from the front, at a three-quarter angle: the same subject, face and working limbs fully visible. Its shoulders ease, it breaks into a small, contented smile and it pushes the flight control forward. Cut to a low aerial tracking shot from behind and to the side. All four thrusters blaze and the silver car shoots upward between buildings, leaving the traffic jam and the beaten monsters far underneath. The camera follows from behind as the car banks into open sky. Finish at 20 seconds with the car clearly flying away over the city. === ACTION DIRECTION === Make every blow feel heavy: full commitment in the body turn, solid contact, deforming armor, recoil and a visible follow-through. Run each move straight into the next. Keep both fighters in frame during contact, and show where each beaten enemy ends up. Favor quick sideways tracking, close foreground parallax and short camera shakes on impact. In frontal shots, keep the pilot's cockpit easy to read. Throughout the video, hold steady the subject, the car's components, the monster designs and the layout of the city.

✍️ Editor’s Notes

The weight of this prompt sits on structure: anchors first, timeline second. An opening paragraph pins the spec, the story summary and the two deadpan jokes. Then === section === blocks set up the subject and cockpit, the world and vehicle, and the monsters on their own, before the seven second-stamped beats begin. The subject is tied to the user's upload and the same person-or-animal, same-cockpit requirement is repeated, trading repetition for shot-to-shot consistency. Car and mech parts are mapped one to one (spine, legs, arms, stabilizers), so the transformations are less likely to drift. The monsters are capped at exactly two with a one-line design each, which stops the model from adding extras. Every beat ends on a hook for the next, fight beats spell out wind-up, contact, deformation and recoil, and a closing ACTION DIRECTION block gathers the feel and camera preferences.
