This project is a node-based implementation for video generation using the Wan2.1 model, with a focus on start and end frame guidance. The source code is a modification of Kijai's nodes code, so for model download and installation instructions, please refer to <a target="_blank" rel="ugc" href="https://github.com/kijai/ComfyUI-WanVideoWrapper">ComfyUI-WanVideoWrapper</a>. This project specifically adds the functionality of start and end frame guided video generation.The nodes support Wan2.1 models in both 720P and 480P versions. It is recommended to generate videos with a frame count of 25 or higher, as a lower frame count may affect the consistency of character identity.Currently, the start and end frame video generation approach is in its early stages. It primarily implements the start and end frame video generation functionality at the code level and does not yet involve model or LoRA fine-tuning, which is planned for future work. Additionally, incorporating end frame guidance in Image-to-Video (I2V) seems to degrade video generation quality, which is another area for future improvement.
