Wan 2.2 14B Fun Inp
Generate videos from start and end frames using Wan 2.2 Fun Inp.
简介
This ComfyUI workflow, titled 'Wan 2.2 14B Fun Inp', is designed to generate videos by interpolating between start and end frames using the Wan 2.2 model. The workflow leverages a series of nodes including CLIPLoader, VAELoader, and ModelSamplingSD3 to load and process the input images, while the WanFunInpaintToVideo node plays a crucial role in creating the video by applying inpainting techniques.
The workflow is particularly useful for creating seamless transitions in videos, making it ideal for artistic video projects or animations where smooth morphing between frames is desired. The use of advanced nodes like KSamplerAdvanced and VAEDecode ensures high-quality video output, while the inclusion of LoraLoaderModelOnly allows for flexible model adjustments.
