Seedance combo 变体 · 分段逐窗流水线

🎧 输入音频（整段配音，seedance 逐窗切分的来源）
① prompt = @image1 首帧 + @audio1 配音参考 + 这一窗台词 + 情绪/手势 hint
② 原始 seedance 画面（未对齐）
③ 对齐后 = 时间轴 warp，嘴动对到配音节奏（还没换嘴形）
④ lipsync 后 = sync-3 换嘴形对配音 + 裁到窗长（拼进最终数字人）
🆚 全片对比（29.2s，音轨=真实配音）：对齐后 不走 lipsync vs 走 lipsync
你说原片已经很好 → 想 EN/DE/JA/KO 直接「原片→对齐→跳过 lipsync」。左边就是这个方案：各窗 v10_warp（时间轴对齐嘴动到配音节奏）裁到窗长后拼接，没做 sync-3 换嘴形。右边是当前 v7 实际产物（多一步 lipsync）。同一条配音，直接看嘴对不对得上。

① 这一窗发给 Seedance 的 prompt
台词：Okay, so tired of those fake ads out there? This one is actually playable, I promise! Just watch these logs get perfectly stripped clean
@image1 = the exact first/starting frame of this clip: the video opens on precisely this image. @audio1 = the voice track of the person speaking. The person in @image1 speaks to camera and says: "Okay, so tired of those fake ads out there? This one is actually playable, I promise! Just watch these logs get perfectly stripped clean". 人物在说话时，做出一些小幅度的手势，点头，微笑，自然的身体动作。相机保持固定，人物保持看向镜头。 One single speaker only, no second person, no clone. No subtitles, no on-screen text, no watermark.
