Openjutsu

Openjutsu is an open-source video character and object swap application built on ComfyUI.

Openjutsu is an open-source tool that lets you swap characters and objects in videos using a local ComfyUI workflow. You provide a video and a character photo to replace the main person while keeping the original camera angles, cuts, motion, and soundtrack. It runs entirely on your own NVIDIA GPU using open weights models such as MiniMax H3, SAM 3.1, and Qwen3-VL. The application offers simple and advanced motion transfer modes, object swapping, background changes, and post-processing tools to fix faces and colors. It is designed for creators and video editors who want local control over AI video generation workflows.
