Seedance 2.5: FLF2V
使用 Seedance 2.5 在用户提供的起始帧和结束帧之间生成平滑的视频过渡，它会自动插值运动、相机移动和视觉演变，同时锁定两个端点。非常适合镜头过渡、故事板预览以及前后场景展示，如从空到满或从白天到夜晚的变化。

[0-1.5s] Starting from the first frame, the camera pushes in from the wide view toward the quiet pool, people standing around the edges, activity not yet started. [1.5-3.5s] Swimmers begin jumping into the pool one after another, splashes erupting, the crowd getting excited and lively, many people in swimsuits leaping in from all sides. [3.5-5s] The camera rises to a top-down view as everyone plays in the water, the pool packed and splashing, landing exactly on the last frame image. No black frames, no jump cuts.\n",
