时长与镜头：原作是 6 秒三段。可灵常见的时长档位是 5 秒和 10 秒：选 5 秒就把三段各压到约 1.5 秒；选 10 秒可以在 2–4 秒那段之后加一段"镜片特写，光带缓缓扫过"。

怎么用：产品图建议用深色或纯色背景、正侧 45 度角的清晰照片作首帧，模型只需要"加光、加运镜"，比从零生成稳定得多。没有产品图时，删掉第一句，当作文生视频使用。

怎么填变量：三种光色最好取品牌色；换成手表就把"沿镜腿平移"改成"沿表带平移"，"镜片光晕"改成"表镜反光"。

常见失败与调整：

• 镜腿在环绕时弯折：把"近距离环绕"改成"缓慢推近"，环绕角度越大越容易崩。
• 光带太乱：只保留一种颜色的光带。
• 标识变成乱码：删掉"[品牌标识]"一句，后期叠加。

Acetate sunglasses rest on a polished black acrylic plinth in a dark studio threaded with thin colored light streaks, the plinth giving a crisp mirror reflection beneath. 0-2s: a motion-control macro slide tracks along the temple arm as a sweeping amber streak runs its full length, revealing tortoiseshell grain and bevel polish, the lenses mirroring the beam. 2-4s: the frame tilts to face camera while twin gradient sources — coral above, electric blue below — glide across the lenses and pull a clean horizontal anamorphic flare. 4-6s: a tight orbit lands on a hero three-quarter, the [brand] temple emblem catching one sharp glint. Frame holds constant shape, hinge position, and lens tint — no bending arms, smearing, or reflection artifacts. Sound: an airy synth swell, a subtle glass shimmer, one resonant chime.
