ComfyUI Extension: ComfyUI-Wan22FMLF

ComfyUI-Wan22FMLF Introduction

ComfyUI-Wan22FMLF is an extension designed to enhance the capabilities of AI artists working with the Wan2.2 A14B I2V models. This extension introduces multi-frame reference conditioning nodes, allowing you to create more dynamic and visually appealing video content by leveraging multiple reference frames. Whether you're looking to create seamless transitions or maintain color stability across frames, ComfyUI-Wan22FMLF provides the tools to achieve these effects efficiently. It addresses common challenges such as frame flickering and color inconsistencies, making it an invaluable asset for artists aiming to produce high-quality video content.

How ComfyUI-Wan22FMLF Works

At its core, ComfyUI-Wan22FMLF operates by using multiple reference frames to guide the generation of video content. Imagine creating a flipbook where each page is a frame of your video. This extension allows you to specify key frames (like the first, middle, and last pages of your flipbook) and then intelligently fills in the gaps to create a smooth transition between them. By using conditioning nodes, the extension can apply specific instructions or "conditions" to each frame, ensuring that the video maintains a consistent look and feel. This process helps in reducing issues like flickering and color shifts, which are common when generating videos frame by frame.

ComfyUI-Wan22FMLF Features

• Multi-Frame Reference Nodes: Supports using 2, 3, 4, or more reference frames, allowing for flexible positioning and enhanced control over the video generation process.
• Structural Repulsion Boost: A feature that enhances motion effects by injecting spatial gradient conditions, particularly useful in high-noise stages to maintain color stability.
• High-Performance Image Selection: Optimized for performance by using server-side file storage, reducing the size of workflow files and improving node loading and response times.
• Customizable Parameters: Offers a range of parameters such as frame positions, noise strengths, and motion enhancement coefficients, allowing for tailored video outputs.

ComfyUI-Wan22FMLF Models

The extension does not introduce new models but enhances the existing Wan2.2 A14B I2V models by providing additional nodes and parameters for better video generation. It is recommended to use official models for optimal performance and avoid quantized models, which may not deliver the same quality.

What's New with ComfyUI-Wan22FMLF

Recent updates have brought significant improvements:

• Performance Optimization: Transitioned to server-side file storage to avoid local storage limitations and improve workflow efficiency.
• Motion Enhancement: Introduced the structural_repulsion_boost parameter to enhance motion effects without compromising color stability.
• Bug Fixes: Resolved issues like frame flickering and improved the stability of the node structure.

Troubleshooting ComfyUI-Wan22FMLF

Here are some common issues and solutions:

• Frame Flickering: Ensure that the high-noise middle frame strength is set between 0.6-0.8 and the low-noise middle frame strength is around 0.2. For complex scenes, consider setting the low-noise middle frame strength to 0.
• Color Inconsistencies: Use the single-person mode to prevent color accumulation and brightness flickering.
• Positioning Errors: If reference frames are not aligning as expected, check the ref_positions parameter and ensure it matches the number of reference images.
