H3 Continuity

H3 Continuity is a ComfyUI custom node pack for authoring and rendering multi-shot video sequences with MiniMax H3.

H3 Continuity is a ComfyUI custom node pack that lets users author and render multi-shot sequences using MiniMax H3 while maintaining visual consistency across cuts. Users lay out films as clips on a timeline, connecting them through continues, cuts, new scenes, or generated bridges. The Studio editor combines a viewer, prompts, pictures, takes, and checks in one place. An optional H3 Story writer plans the timeline from an idea using any OpenAI-compatible endpoint. The tool also includes audio lanes, timed text, and a versioned HTTP API with a Python client for headless rendering.
