180 °水平转动，像自转的地球仪 ，45°俯视角度, 不要添加任何额外的组件
Description
Convert this wheel hub bearing product image into a realistic commercial product video. The product remains exactly the same wheel hub bearing shown in the source image. Rotate the product smoothly from left to right through 180 degrees at a constant speed, revealing the opposite side of the product. The product must maintain its original shape, structure, proportions, components, materials, colors, markings, and surface details throughout the entire video. Keep the product perfectly centered and level. The left and right ends of the bearing remain at the same height during the rotation. The camera is fixed at a 45-degree downward viewing angle and does not move. No zoom, pan, tilt, orbit, or camera motion. Only the existing product rotates. Do not add any new parts, supports, turntables, rotation axes, fixtures, or background elements. Maintain realistic studio lighting, reflections, focus, and exposure. Smooth professional product showcase animation, constant motion, no jitter, no wobble, no deformation, no morphing, no redesign.
Prompt Content
Convert this wheel hub bearing product image into a high-quality commercial product video.
Animate the existing product only. The product must rotate smoothly from left to right through exactly 180 degrees at a perfectly constant angular velocity.
IMPORTANT:
The rotation is a motion transformation applied to the existing product only. Do not generate, add, visualize, reveal, or imply any rotation mechanism, support structure, spindle, rod, shaft, turntable, pedestal, mounting device, center axis object, CGI helper geometry, or any other additional element.
The final video must contain exactly the same product and exactly the same product components visible in the original image.
Product integrity is critical:
* Preserve 100% of the original product layout, geometry, proportions, dimensions, components, materials, markings, textures, colors, finishes, and surface details.
* Do not add, remove, replace, simplify, enhance, redesign, reconstruct, or invent any product feature.
* No extra holes, shafts, rods, supports, caps, mechanical parts, reflections, decorations, or structural elements.
* No hidden areas should be filled with AI-generated components that do not belong to the original product.
* The output must remain the identical wheel hub bearing shown in the source image.
Orientation requirements:
* The product's main centerline must remain perfectly horizontal and level throughout the animation.
* The left and right ends must remain at exactly the same height.
* No tilt, roll, pitch, wobble, drift, deformation, or axis deviation.
* Maintain the exact original orientation relationship between all product components.
Camera requirements:
* Fixed camera position.
* Fixed viewing angle approximately 45° downward from above.
* No zoom, pan, tilt, orbit, dolly movement, reframing, or perspective changes.
* Only the existing product rotates.
Motion quality:
* Smooth, continuous, frame-perfect motion at 30–60 fps.
* No jitter, vibration, frame skipping, acceleration, deceleration, speed fluctuation, or uneven rotation.
* Constant rotational speed from the first frame to the last frame.
Lighting and composition:
* Keep the product perfectly centered.
* Maintain consistent studio lighting, reflections, shadows, focus, exposure, and white balance.
* Preserve a realistic industrial product-photography appearance.
Negative constraints:
* No 3D support axis.
* No turntable.
* No pedestal.
* No mounting fixture.
* No floating helper geometry.
* No CGI rotation rig.
* No additional mechanical parts.
* No added or removed elements of any kind.
* The video must show only the original product, rotating by itself.
