What is it?

H3 Continuity is a ComfyUI custom node pack for building and rendering video sequences with MiniMax H3. A Timeline organizes clips and carries context from one clip to the next, while a Studio adds story, reference and timeline editing. The pack also includes nodes for saved segments, stills and H3 context windows.

Visual memory lets selected moments from earlier clips inform a later shot, including after an exterior scene or a camera-angle change. H3 Story can plan and write the Timeline through an OpenAI-compatible endpoint, either local or cloud-hosted.

Running it requires a current ComfyUI installation with MiniMax H3 support, the matching model files, and a GPU for generation. Model weights and the optional H3 prompt guides are not included and are subject to separate MiniMax terms.

Key features

  • 01Timeline for organizing clips that continue from earlier shots.
