+**Sound-to-Video Workflow Enhancements & Model Support Expansion**
+
+This release focuses on improving audio-visual workflow capabilities and expanding model support, particularly for sound-to-video generation and the latest Wan2.2 5B models:
+
+**Sound-to-Video Workflow Control**
+- **WanSoundImageToVideoExtend Node**: New manual video extension node for sound-to-video workflows, giving creators precise control over generated video length and timing. This enables fine-tuned control over how audio content translates to video sequences.
+- **Audio-Video Synchronization**: Fixed critical issue where extending video past audio length caused workflow failures, ensuring reliable sound-to-video generation regardless of audio duration.
+- **Automatic Audio Trimming**: Video saves now automatically trim audio to match video length, eliminating audio-video sync issues in final output files.
+
+**Advanced Latent Processing**
+- **LatentCut Node**: New node for cutting latents at precise points, enabling more granular control over latent space manipulation in complex generation workflows. This is particularly useful for batch processing and temporal video workflows.
+
+**Wan2.2 5B Model Integration**
+- **Fun Control Model Support**: Added support for Wan2.2 5B fun control model, expanding creative control options for video generation with enhanced parameter manipulation.
+- **Fun Inpaint Model Support**: Integrated Wan2.2 5B fun inpaint model, providing advanced inpainting capabilities for video workflows with improved quality and consistency.
+
+**Template System Updates**
+- **Template v0.1.70**: Updated template system with latest model integrations and workflow examples, ensuring users have access to optimized setups for new features.
+
+These improvements significantly enhance ComfyUI's capabilities for audio-visual content creation, providing more reliable sound-to-video workflows and expanded creative control through the latest Wan2.2 model series.

+**音频转视频工作流增强与模型支持扩展**
+
+本次发布专注于改进音视频工作流功能并扩展模型支持，特别是针对音频转视频生成和最新的Wan2.2 5B模型：
+
+**音频转视频工作流控制**
+- **WanSoundImageToVideoExtend节点**：全新的音频转视频工作流手动视频扩展节点，为创作者提供对生成视频长度和时间的精确控制。这使得对音频内容如何转换为视频序列的精细调控成为可能。
+- **音视频同步**：修复了当视频扩展超过音频长度时导致工作流失败的关键问题，确保无论音频持续时间如何都能可靠地生成音频转视频内容。
+- **自动音频裁剪**：视频保存现在会自动将音频裁剪至匹配视频长度，消除最终输出文件中的音视频同步问题。
+
+**高级潜在空间处理**
+- **LatentCut节点**：用于在精确点位切割潜在变量的新节点，在复杂生成工作流中实现对潜在空间操作的更精细控制。这对于批处理和时序视频工作流特别有用。
+
+**Wan2.2 5B模型集成**
+- **Fun Control模型支持**：增加了对Wan2.2 5B fun control模型的支持，通过增强的参数操作为视频生成扩展了创意控制选项。
+- **Fun Inpaint模型支持**：集成了Wan2.2 5B fun inpaint模型，为视频工作流提供高级修复功能，具有更好的质量和一致性。
+
+**模板系统更新**
+- **模板v0.1.70**：更新了模板系统，集成了最新的模型和工作流示例，确保用户能够访问针对新功能优化的设置。
+
+这些改进显著增强了ComfyUI在音视频内容创作方面的能力，通过最新的Wan2.2模型系列提供了更可靠的音频转视频工作流和扩展的创意控制。
