# ComfyUI MiniMax H3 Multiframe Reference Workflow
> Generate MiniMax H3 video continuations and multi-shot scenes in ComfyUI by anchoring reference frames at specific points along the output timeline with Add Guide nodes.
Generate video continuations and multi-shot scenes by anchoring reference frames at specific points along the output timeline. The workflow combines the Reference to Video node with chained Add Guide nodes: each Add Guide pins a still image (plus optional audio) to a frame index, so the video passes through that exact composition at that moment.

Identity reference and first frame of Shot 1, or use your own images.
Keyframe anchored at 1.5s (Shot 2), or use your own images.
Keyframe anchored at 3.0s (Shot 3), or use your own images.
First frame anchored at 5.0s (Shot 4), or use your own images.

## Prompting tips
1. **Reference by tag**: `` is the image connected to the first `ref_images` slot, `` the second, and so on. In this workflow, `` is both the identity lock and the first frame of the video
2. **Timeline anchors vs references**: Pictures connected only to Add Guide nodes pin compositions at specific frames but are not visible to the text encoder. Plug them into extra `ref_images` slots too if the prompt should see them as ``
3. **Frame index**: Each Add Guide takes `frame_idx` in frames at 24fps; the template computes it from seconds with `round(seconds * 24)`. Negative values count from the end of the video. The index plus the guide length must stay inside the generated duration
4. **Add more keyframes**: Copy one guide block (Load Image + Frame Index + Math Expression + Add Guide for MiniMax H3) and keep the `positive` outputs chained in series into the Basic Guider
5. **Turbo mode (optional)**: Enable the **Lightning LoRA** checkbox to use the 4-step turbo LoRA for much faster generation, with slightly lower audio and motion quality
## Prompt writing guide
The template prompt follows the [full-reference mode prompt guide](https://huggingface.co/MiniMaxAI/MiniMax-H3/blob/main/docs/VIDEO_PROMPT_WRITING_GUIDE_ref_en.md): it defines each subject, maps each `` to a shot's first frame or keyframe, and cuts between shots at explicit timestamps. Use the same structure when writing your own multi-shot prompts. The guide is summarized in the [prompt guide](/tutorials/video/minimax/minimax-h3-prompt-guide).
