🚀 WanVideo Model Suite

Combined & Quantized Models for ComfyUI Workflows
Derived from Wan-AI/Wan2.1-VACE-14B

---

📋 Overview

This repository provides optimized models for WanVideo—a high-fidelity video generation framework. Models are quantized to balance performance and resource efficiency while retaining visual quality. Designed for seamless integration with ComfyUI via:

• WanVideo Wrapper (Third-party extension)
• Native WanVideo nodes in ComfyUI

🔧 Key Components

1. Core Diffusion Models

File	Size	Description
wan2.1_i2v_720p_14B_fp8_e4m3fn.safetensors	Quantized (FP8)	Base video generation model (14B params, 720p).
fantasytalking_fp16.safetensors	FP16	Specialized model for expressive dialogue animation.

2. Text & Vision Encoders

File	Type	Role
umt5-xxl-enc-bf16.safetensors	Text Encoder (UMT5-XXL)	BF16 precision for multilingual text understanding.
clip_vision_h.safetensors	Vision Encoder	Processes visual inputs for conditional generation.

🔗 Dependencies & Resources

1. Vision Encoder Resources

   • Download clip_vision_h.safetensors from:
     Comfy-Org/Wan_2.1_ComfyUI_repackaged

2. FantasyTalking Model

   • Source code & usage: GitHub Repository

3. Base Model

   • Full precision version: Wan-AI/Wan2.1-VACE-14B

💡 Usage Notes

• Quantization Benefits: FP8 reduces VRAM usage by ~50% vs FP16, enabling 720p generation on consumer GPUs.
• Workflow Compatibility: Combine with Text-to-Video, Image-to-Video, or FantasyTalking nodes in ComfyUI.
• Multi-Modal Inputs: UMT5-XXL encoder supports multilingual prompts (e.g., English, Chinese).
