Wan2ReferenceVideoApi - ComfyUI Built-in Node Documentation

This node generates a video featuring a person or object based on provided reference materials. It uses the Wan 2.7 model to create videos from a text prompt, supporting single-character performances and multi-character interactions. You must provide at least one reference video or image for the generation to work.
