Create an 8-12 second stylized or cinematic action video following [RIDER] from behind as they move down a steep winding road, trail, or path on [BOARD_OR_VEHICLE]. Use a fast FPV chase camera, wide-angle perspective, wind rush, and strong forward momentum. Start in [START_SEASON] with clear environmental cues such as green hills, bright sky, ocean distance, autumn leaves, city trees, or dry road texture. Around the 3-second mark, let a visible transition wave emerge from the rider, board, wheels, or road surface and replace the environment into [END_SEASON]. The change should be seamless: ground texture, roadside objects, sky, weather particles, vegetation, and distant mountains or skyline all transform while the rider and camera path remain continuous. Keep the camera locked behind the rider; do not cut away during the season replacement. Use high-energy motion, readable silhouettes, clean depth, and natural lighting continuity across the change. Avoid logos, text, duplicated riders, warped wheels, impossible road geometry, broken camera direction, or a transition that looks like a hard scene cut instead of an in-motion replacement.
