Flying Car AI：一张照片，完成坡道特技

Edit Video1. Replace ONLY the single moving hero van with the complete subject or complete rider-and-mount assembly in Image1. Image1 supplies identity, body shape, clothing or fur, accessories and the entire mount when present; never copy its background. Preserve the night stunt arena, tall red-edged curved ramp, parked background cars, spectators, lighting, all camera movements, shot sequence and original action timing. Track the same hero through the ground approach, full ramp climb, airborne stunt, upright smoke landing and final showcase. For a rider and horse, preserve their connection throughout and use coherent natural legs; never add vehicle parts or wheels to an animal. Replace no background subject. No new location, extra action, duplicate hero, cuts to the photo, text or soundtrack. Complete the original full stunt and ending within 15 seconds.
