这是一款基于 LTX 2.3 的音频驱动角色替换视频应用。
上传一张角色参考图、一段参考动作视频和一段驱动音频，应用会在尽量保留原动作节奏和镜头运动的前提下，让参考角色跟随动作视频进行表演，并结合音频长度输出最终视频。它更适合做“参考角色跟着动作视频动，并由音频驱动整段时长和节奏”的效果。
推荐这样使用：
-
角色参考图尽量选择单主体、正脸清晰、背景干净的图片
-
参考动作视频尽量选择单主体、动作明确、遮挡少、镜头不要太乱的片段
-
驱动音频尽量选择人声清楚、时长适中的音频
-
更适合“角色一致 + 动作跟随 + 音频同步”的镜头，不适合多人复杂场面
-
想让结果更稳定，可以强调“主体一致、动作连贯、无额外人物、无突变场景、镜头稳定”
推荐输入示例：
参考图中的角色跟随参考动作视频进行自然表演，并与驱动音频节奏协调，动作连贯，主体一致，镜头稳定，细节清晰，光影自然，无多余人物。
