OPENjutsu
Type: ComfyUICategory: Generation
OPENjutsu is a ComfyUI workflow or node pack in our Generation category. Comfy Org's MIT character-swap app: replace a character in an existing clip while keeping motion, camera and timing, built on the akatz-labs H3 workflow with MiniMax H3 + SAM 3.1. Per the README it deploys to the Comfy Developer Platform (96 GB RTX PRO 6000, ~2 min per warm 5 s 480p part, deployment credits), 5-15 s parts at 480/768, optional GPT Image 2.5 first frame; also usable as a Comfy Hub app. Use only footage and likenesses you have rights and consent for.
Where it fits: ComfyUI, Open-weight video & audio models.
