Vol en wingsuit dans une gorge alpine

Prompt anglais

Create an ultra-photorealistic, intensely exhilarating 15-second sequence following a wingsuit athlete through a steep alpine corridor. The athlete flies downhill while the camera overtakes, dives, banks around rock, passes falling water, and accelerates outward into enormous open space. Astonishing flight, aggressive camera motion, and continuously changing terrain create the spectacle. Every second reveals new depth, foreground geometry, and a new relationship between athlete and mountain. EXACTLY 15 SECONDS. ONE ABSOLUTELY UNBROKEN PHYSICAL CAMERA TAKE. No cuts, hidden edits, transitions, slow motion, speed ramps, or teleportation. Begin at full flight speed and sustain real-time motion through the final frame. Give the camera its own continuous airborne route, fixed lens, rotating head, and visible momentum. This fictional cinematic flight must preserve gravity, airflow, distance, and terrain. THE CONNECTED ROUTE Build one compact drainage, roughly half a kilometer along the descending flight line, with substantial continuous elevation loss. Connect four environments: a sunlit granite shoulder, a broad blue-shadowed gorge, a waterfall recess on its right wall, and a vast sunlit valley. Follow one broad left bend downhill. Reveal each next section through the preceding opening before reaching it. Pale granite, sparse grass, and old snow patches cover the opening ridge. Below, dark walls compress the view into a broad gorge. A rock nose projects from the outer right edge of its bend. Immediately beyond, water falls down the same wall into a stream far below. Past this recess, the walls separate rapidly, exposing a deep valley with distant forest bands and a silver river. Keep this a connected alpine landscape. Use one athlete in a burnt-orange wingsuit with charcoal undersides, a dark helmet, and compact parachute pack. Airflow tensions the arm and leg fabric. Keep identity, suit panels, and proportions fixed. Small consequential adjustments steer the descending glide: a shoulder settles, a hip shifts, one side loads into a bank. No flapping, upward kicking, or powered superhero flight. CAMERA ROUTE AT A GLANCE Start behind and right. Overtake on that side, panning to retain the athlete, then dip below them as the gorge opens. Follow the outside of the left bend around the rock nose. Pass alongside the waterfall through clear air. At the valley opening, peel outward while the athlete flies ahead, creating a wide rear three-quarter angle without reversing direction. 0-3 SECONDS: OVERTAKE THE RIDGE BEGIN IN VIOLENT FORWARD MOTION. A granite tooth tears past the lower-right foreground as the athlete streaks across the ridge shoulder. Frame one contains rushing stone, a tensioned wing edge, and the drop beyond. The athlete banks left, clearing the descending shoulder toward the darker gorge. Their extended body stays purposeful; rapidly passing rock makes speed unmistakable. The camera surges from the rear-right quarter to the athlete's shoulder, revealing the gorge entrance ahead while briefly alongside. It then overtakes and pans smoothly back toward the athlete, changing to a forceful three-quarter view of helmet, chest, and wing. Bank the image with the turn, then begin easing the horizon toward level. A second fixed granite fin races along the near bottom edge, producing a strong foreground wipe that never covers the full frame. As the camera enters the gorge, enclosing shadow replaces open ridge light. The sunny shoulder recedes behind the athlete without a visual reset. 3-6 SECONDS: DROP INTO THE GORGE The athlete crosses the ridge edge on the same downhill line. Their orange silhouette separates against a distant dark wall, making the drop readable. The athlete commits to a steeper descending bank through the broad left arc. Show the suit loading into airflow, with fabric tremors trailing toward the feet. Make the steep bank and plunging terrain read as one forceful, controlled maneuver. Now drive the camera downward and forward in a sweeping dive below the athlete's level. Rotate the head upward just enough to keep the suit in view while the gorge floor opens behind and beneath them. A close ledge races upward through the lower foreground because the camera is descending past it. Its movement must agree with the rig's actual path. The visual field changes from open pale ridge to enclosing blue-gray rock, with a narrow bright strip of sky above. Keep the athlete readable against alternating light and shadow. End this interval with the camera below and ahead on the right, already approaching the next broad bend rather than preparing a disconnected new maneuver. 6-9 SECONDS: BANK AROUND THE ROCK NOSE The athlete carves the established left arc, body and wing fabric tilting together. A distant river line moves slowly while nearby rock races sideways, exaggerating depth. Their route clears the projecting granite nose along the continuous line anticipated in the preceding seconds. The camera takes a wider line on the outside of the turn and banks aggressively around the near end of the fixed rock nose. Bring its fractured surface close to one side of the image, letting cracks and mineral seams streak past while the athlete stays visible across the open center. The camera's greater outside arc allows the athlete to draw closer along their shorter route. Recover the relative height difference by descending less steeply for a moment, never by launching upward. As the rock nose slides away, reveal an entirely new silver-white waterfall against a charcoal recess. The waterfall has been physically behind this projection all along. This is a fast, motivated reveal with a visible path around the obstacle. 9-12 SECONDS: CROSS THE WATERFALL RECESS The athlete passes beside the waterfall in clear air, with its curtain to their right and open gorge beneath. They ease toward level as the course straightens. Orange fabric flashes against white water, then dark rock behind scattered droplets. Keep the athlete visible throughout this rapid succession of backgrounds. Accelerate the camera along the outer right side of the flight corridor, passing near the waterfall's open edge. A narrow fringe of fine droplets streaks across the extreme foreground while the main falling column remains off to the right. Keep most of the lens clear so the athlete, cliff, and outgoing route remain continuously visible. Sweep the camera head from the waterfall edge back across the athlete as the rig advances, creating a powerful sideways rush of water against slower distant rock. Through the exit ahead, reveal sunlight, a widening valley, and a dramatically lower river. By second twelve, the camera and athlete are leaving the same shadowed recess, with sunlight starting to travel across their surfaces. 12-15 SECONDS: PULL INTO THE DEPTH The athlete bursts into the valley on the same descending trajectory, leveling out of the bank while maintaining speed. Sunlight outlines orange fabric. Tight walls vanish from the composition's sides, revealing layered cliffs, distant forest, and the silver river. Make the newly available space feel enormous while preserving the flight's connection to the gorge. The camera now peels outward rapidly into that open air, allowing the athlete to move ahead. The rig keeps traveling forward and downward on a diverging arc; it does not fly backward. Pan smoothly into a rear three-quarter view as the separation grows. A final rock spur races past the lower edge, then drops completely out of the foreground, removing the last nearby depth reference. This makes the valley appear to expand violently around the shrinking orange figure. Continue the pull outward through the final second, with the athlete racing toward the distant bend and the gorge mouth still visible behind and to one side. End at exactly fifteen seconds during active flight. No landing, parachute deployment, freeze frame, fade, or static scenic hold. LENS PARALLAX AND VELOCITY Use one fixed wide cinematic lens, approximately 21 mm in full-frame terms, with natural rectilinear perspective. Obtain the opening close view through camera position and the final wide reveal through increasing physical separation. Avoid a zoom that substitutes for travel. Keep the athlete large enough to read during the overtake and gorge passage, then allow them to become a smaller, unmistakable orange shape as the valley opens. The changing scale is part of the payoff. Build speed from layered movement: granite teeth and ledges slash across the foreground, the athlete holds a readable position in the middle distance, and remote mountains move slowly. Place each near object beside an open flight channel so the camera can actually pass it. Bank strongly during the rock maneuver, but let the roll settle progressively into the next line. Camera-head pans can be fast; the airborne rig's translation follows broad connected arcs. Preserve enough motion blur to make close rock feel fast without dissolving the athlete into a smear. No arbitrary orbit, instant stop, or direction reversal interrupts the route. FORCE LIGHT AND SOUND CONTINUITY Air presses the wingsuit into shape. Ripples stream backward; helmet and pack stay anchored. The athlete loses altitude continuously, banking through forward curves. Water falls into the same stream; fine spray drifts with airflow. The camera never crosses solid stone or the athlete's body. Real boundaries change the light: bright ridge, cold gorge shadow, luminous water against dark rock, then valley sun. Let these sweep across athlete and terrain in order. Adapt exposure smoothly, retaining fabric and water detail, natural rock color, and a readable horizon during banking. Use a continuous close rush of air, cloth vibration, and restrained equipment noise. Gorge walls add changing acoustic enclosure. The waterfall grows louder on approach and falls behind as the valley opens. No dialogue or explanatory title is needed. Let air speed dominate the last pull into space. The final impression must be breathtaking momentum through a mountain that continually changes around the viewer: one athlete, one connected descent, one fiercely dynamic camera, and fifteen uninterrupted seconds of expanding physical scale.
