cinematic video showing a lone astronaut in a pristine white spacesuit, kneeling on a vast expanse

⁣A 4K cinematic video showing a lone astronaut in a pristine white spacesuit, kneeling on a vast expanse of snow-covered ground with jagged mountains in the background under a bright, clear sky. The camera starts with a medium shot of the astronaut, focusing on their posture and the detailed texture of their suit, highlighting the American flag patch on their shoulder. The camera slowly zooms in to a close-up on their helmet, where the reflection of the surrounding snow-covered landscape can be subtly seen within the visor. As the camera focuses on the astronaut, it smoothly orbits the figure in a clockwise direction, showcasing their backpack and the intricate details of their equipment. The movement is smooth and deliberate, creating a sense of isolation and wonder. As the orbit concludes, the camera transitions to an eye-level perspective, slowly pulling back to reveal the vastness of the snowy environment and the sharp, craggy mountains that rise in the distance. Focus is kept sharply on the astronaut throughout the shot, the crisp quality making them the prominent element within the expansive environment. The snowy ground should have a fine granular texture, with small drifts and undulations, the sunlight reflecting off the surface. The lighting should be natural and bright, casting crisp, well-defined shadows from the astronaut onto the snow. Subtle wind effects should be introduced as a gentle flow of fine snow that moves across the scene, while the astronaut remains still. Maintain a professional, cinematic feel throughout, emphasizing the high-resolution details, dynamic lighting, and the astronaut's solitude in this starkly beautiful alien landscape. This video should feel like an opening establishing shot in a high-budget Sci-Fi film. The overall tone is a blend of isolation, wonder, and the stark beauty of the environment. Emphasize extreme detail, ensuring the rendering is perfect and the movement fluid, generating a smooth 4k video.
