这是一款基于 LTX2.3 Dev-Dare TIES 蒸馏1.1 + LipDub IC LoRA + OmniNFT 增强 + VBVR 时序稳定 + Motion Track Control + PromptRelay Smart 分段脚本 + AudioRefTokens + 三阶渲染 的视频重说话应用。用户上传一段原视频后，可以填写新的全局画面规则和分段台词脚本，让人物在尽量保持原视频身份、场景、镜头、背景和身体动作的前提下，重新说一段新的内容，并生成新的自然嘴型。
这条流的核心优势是：不是重新生成一个数字人，而是在原视频基础上“换词对口型”。 它适合做视频改口播、外语/中文重配音、明星感问候片、角色重新说台词、短剧补对白、产品口播重录、旧素材二次改文案、AI视频救片和多语言本地化内容。相比普通图生视频或单图数字人，它更强调 原视频保持 + 新台词嘴型同步：原视频提供人物、场景、动作和镜头，新台词 / 新音频提供嘴型节奏，LipDub IC LoRA 和 AudioRefTokens 负责把嘴巴运动重新对齐。使用时建议重点控制四项：输入视频决定原始画面，新台词脚本决定说什么，音频 / AudioRefTokens 决定对口型节奏，LipSync Guide 强度决定原视频保持程度。
