Paper Plane Seasonal Journey Video

Generate a 15-second, 16:9, 720p realistic cinematic fantasy short film. The entire film features a single off-white hand-folded paper plane as the sole protagonist, with consistent paper texture, fold lines, size, and flight direction throughout. Use a one-take low-altitude following shot, with the camera positioned about half a meter behind the paper plane, moving steadily forward without sudden cuts or clipping. 0 to 3.5 seconds: A spring morning street in an old town, cherry blossoms drifting in the breeze. The paper plane flies out of an open classroom window, and the camera immediately follows. Soft morning light, clear air, with sounds of wind, distant birds, and a very light piano intro. 3.5 to 7 seconds: The paper plane glides behind a foreground tree canopy, completing a natural transition through occlusion. The street enters a midsummer afternoon with thick shade and a brief rain shower; small water droplets appear on the paper surface without damaging or deforming it. The camera maintains the same distance and direction of movement, with rain sounds and piano rhythm slightly intensifying. 7 to 10.5 seconds: The paper plane flies close to a passing old bus, using the vehicle body for a transition into a late autumn twilight. Golden fallen leaves swirl in the same wind direction, and the setting sun illuminates the paper plane's folds from the right. It briefly dips before being lifted by an air current again, moving according to air resistance without teleporting. 10.5 to 15 seconds: The paper plane passes through a patch of foreground white mist, and the street enters a quiet winter night with thin snow covering the eaves and road. The camera gradually moves to the front side of the paper plane, revealing an eight-year-old boy in a navy cotton coat at an alley entrance. He raises his hand to catch the paper plane and looks down to see a line of childish pencil handwriting on the inside of the wing: 'To my future self'. The boy pauses for a second, looking up in the direction the paper plane came from. The piano leaves only a final note, and the scene stops naturally. The four seasons must occur on the same street and flight path, with continuous architectural space, screen orientation, and camera axes. There is only one paper plane throughout, with no changes in color, material, folding method, or size. Seasonal changes are achieved only through occlusion transitions, lighting, vegetation, weather, and ambient sounds. No additional paper planes, sudden appearances or disappearances of characters, garbled text, melting paper, jump cuts, flickering frames, platform watermarks, subtitles, narration, or extra dialogue.
