节点特点

专为 Wan2.2 双模型工作流优化的 InfiniteTalk 对口型节点，支持首尾帧精确控制

• 帧率同步控制：新增 video_fps 参数，可自定义设置视频帧率（1-120fps），音频口型自动匹配该帧率，完美解决原生硬编码 25fps 导致的音画不同步问题

• Wan2.2 双模型架构：同时支持高噪模型（0-2步）和低噪模型（2-4步）并行打补丁，保持与官方工作流完全一致

• 三模式首帧控制：

  • 仅首帧：传入 start_image，视频从首帧开始生成并全程对口型
  • 仅尾帧：传入 end_image，视频最终定格指定画面并对口型
  • 首尾帧：同时传入 start_image 和 end_image，视频从首帧自然过渡到尾帧，全程精准对口型

• 提示词动作运镜控制：继承 Wan2.2 强大的提示词理解能力，可通过文本精确控制人物动作、相机运镜和场景变化

• 全功能保留：支持单人/双人对口型、motion context、previous frames 延续生成等所有原生功能

• 图片+音频 生视频

Node Features

InfiniteTalk lip-sync node optimized for Wan2.2 dual-model workflow with first/last frame precision control

• FPS Synchronization Control: New video_fps parameter allows custom video frame rate settings (1-120fps), with audio lip-sync automatically matching the specified rate, completely solving audio-visual desynchronization caused by the original hard-coded 25fps
• Wan2.2 Dual-Model Architecture: Simultaneously patches both high-noise (0-2 steps) and low-noise (2-4 steps) models, maintaining full compatibility with official workflows
• Three First/Last Frame Modes:
  • First frame only: Pass start_image to generate video from first frame with continuous lip-sync
  • Last frame only: Pass end_image to end video at specified frame with lip-sync
  • First & Last frames: Pass both start_image and end_image for natural transition from start to end with precise lip-sync throughout
• Prompt-Controlled Motion & Camera: Inherits Wan2.2's powerful prompt comprehension, enabling precise control of character movements, camera operations, and scene changes through text prompts
• Full Feature Retention: Supports all native features including single/dual speaker lip-sync, motion context, and previous frames continuation
