目前轮毂单元视频旋转会出现4s之后旋转角度混乱，增加元素，改变形状的错误，下面提示词用千问视频生成模型不会出现，但是物体会逐渐从小到大
中文提示词： 将这个轮毂轴承单元图片转换成从左到右沿着中心轴旋转的视频，就像地球自转一样进行自转的视频，不要增加，删除，修改产品的任何元素，形状，严格保持产品的一致性
Description
Prompt Content
Convert the uploaded wheel hub bearing product image into a realistic commercial product video.
The product in every frame must remain the exact same wheel hub bearing as shown in the source image. Product identity preservation is the highest priority.
Keep all original geometry, contours, proportions, holes, edges, bolt positions, bearing components, metal surfaces, markings, textures, and mechanical details unchanged throughout the entire video.
Animate only a smooth, controlled horizontal rotation of the existing product. The product rotates as a single rigid object. All components remain locked together and maintain their original positions relative to each other.
The rotation must be slow, stable, and continuous, with no wobble, vibration, deformation, morphing, reconstruction, regeneration, or redesign.
The product's centerline remains perfectly level. The left and right ends remain at the same height throughout the animation.
The camera remains completely fixed at a 45-degree downward viewing angle. No camera movement, zoom, pan, tilt, orbit, reframing, or perspective changes.
No new geometry may appear at any time. Do not add bolts, rings, holes, shafts, supports, fixtures, mechanical parts, metal structures, labels, logos, reflections, or any other elements not present in the source image.
Do not reconstruct or reinterpret the product. Maintain the exact product appearance from the first frame to the last frame.
Clean studio background. Consistent lighting, reflections, focus, and exposure.
Short product showcase animation, 2–3 seconds duration, smooth constant motion, ending before any additional movement or shape changes occur.
