LTX2.3 文生视频 3.1 是一款图文生成短视频工作流，能够根据 上传的参考图片 + 全局提示词 + 分段提示词 自动生成高清短视频。
特点如下：
-
参考图锁定主体：上传参考图像后，系统会保持角色身份、服装、发型和主要特征稳定。
-
全局提示词控制整体画面：定义视频场景、光影、动作边界、画风和镜头规则，保证画面风格一致。
-
分段提示词控制动作：可针对视频每个时间段设置动作变化，角色表情、动作连贯。
-
三阶采样高清精修：生成的视频经过三阶采样，输出清晰、高精度画面，减少噪点和杂乱装饰。
-
10S相似度保持：通过相似度引导和锚点约束，保证视频中角色与参考图高度一致，动作自然。
-
支持音画分离：可选择音频输入，实现口型同步或动画动作匹配。
-
操作简单：上传图片和输入文本即可生成视频，无需手动分段渲染。
