Convert this wheel hub bearing product image into a smooth product showcase video. Keep the wheel hub bearing perfectly fixed at the center of the frame at all times. Only apply a slow horizontal left-to-right rotation along its original central axis. Do not zoom in, zoom out, move, translate, tilt, deform, morph, or change the camera position. Maintain the exact original structure, proportions, shape, color, texture, lighting, reflections, and all components of the product without any modifications or additions. The background must remain stable and unchanged. Ensure the rotation is clean, realistic, mechanically accurate, and continuous, with no shaking, floating, scaling, or perspective shifts.
修改后提示词：
Convert this wheel hub bearing product image into a smooth product showcase video. Keep the wheel hub bearing perfectly fixed at the center of the frame at all times. Apply a continuous, natural-speed horizontal left-to-right rotation along its original central axis that looks visually comfortable to the human eye. Do not zoom in, zoom out, move, translate, tilt, deform, morph, or change the camera position. Maintain the exact original structure, proportions, shape, color, texture, lighting, reflections, and all components of the product without any modifications or additions. The background must remain stable and unchanged. Ensure the rotation is clean, realistic, mechanically accurate, and continuous, with no shaking, floating, scaling, or perspective shifts.
“natural-speed” 或者 “visually comfortable rotation speed” 比单纯的 “slow” 更容易让 AI 生成适合观看的速度。 如果 AI 仍然太慢，可以加上明确帧率或旋转角度提示，例如：“rotate at approximately 30–45 degrees per second horizontally.”
Convert this wheel hub bearing product image into a high-quality product showcase video. The wheel hub bearing must remain perfectly fixed at the center of the frame at all times. Apply a continuous horizontal left-to-right rotation along its original central axis at a visually comfortable speed of approximately 30–45 degrees per second, so that the motion looks smooth, natural, and mechanically accurate to the human eye. Do not zoom in, zoom out, move, translate, tilt, deform, morph, or change the camera position. Maintain the exact original structure, proportions, shape, color, texture, lighting, reflections, and all components of the product without any modifications or additions. The background must remain stable and unchanged. Ensure the rotation is clean, realistic, continuous, and fluid, with no shaking, floating, scaling, or perspective shifts. The final video should feel like a professional product showcase with precise, mechanical motion.
- 你也可以把 “30–45 degrees per second” 调整成你自己觉得最舒服的速度，如果太慢就提高到 50°/秒，太快就降低到 20–25°/秒。
- 保持 “continuous” 和 “mechanically accurate” 关键字，这样 AI 不会断断续续或产生漂浮感。
如果你愿意，我可以帮你再做一个**更短更精炼的版本**，用于一些生成视频平台（比如 Runway、Kaiber、Pika Labs）直接粘贴就能用，避免提示词太长被截断。
