H3 Continuity is a ComfyUI custom node pack for authoring and rendering sequences with MiniMax H3. Its Timeline organizes clips and carries context across continuing clips; the Studio adds story, reference and timeline editing, plus nodes for saved segments, stills and H3 context windows.
Visual memory can bring selected moments from earlier clips into a later shot, including after an exterior scene or a camera-angle change. H3 Story can plan and write the Timeline through any OpenAI-compatible endpoint, local or cloud.
