# ComfyUI MiniMax H3 Text-to-Video, Image-to-Video, and Reference-to-Video Workflows
> Run MiniMax H3 text-to-video (T2V), image-to-video (I2V), and reference-to-video (R2V) workflows in ComfyUI, plus advanced native-node techniques for guide anchoring and latent noise masks.
This page covers the three base MiniMax H3 template workflows in ComfyUI, plus advanced techniques built on the native H3 nodes. For model capabilities, prompt writing, and speedups, see the [MiniMax H3 overview](/tutorials/video/minimax/minimax-h3).
## MiniMax H3 Text to Video (T2V)
Generate videos from text prompts with native stereo audio.

### Prompting tips
1. **Describe the whole scene**: State the overall scene first (location, character, what is happening), then break it into timed shots
2. **Shots, camera, and audio**: Describe the shots, camera moves, and the accompanying audio (dialogue, SFX, music) in one prompt block
3. **Resolution**: H3's native canvas is a 768px short edge, which is 1344x768 at 16:9, and resolutions are rounded to a multiple of 32
4. **Duration**: The duration input snaps to the model's 17-frame-per-block (17k+5) grid at 24fps
5. **First/last frame**: Connect images to `first_frame` and/or `last_frame` on the `MiniMaxH3ImageToVideo` node to turn this workflow into first/last-frame image-to-video
6. **Turbo mode (optional)**: The workflow generates at 20 steps by default; raise the step count (for example to 25) for better motion quality. Enable `turbo_mode` on the MiniMax H3 node to use the included Lightning LoRA (`minimax_h3_fl2v_turbo_8step_v1.0_comfyui_bf16`) at 8 steps for much faster generation, with slightly lower audio and motion quality
The official base-mode [prompt writing guide](https://huggingface.co/MiniMaxAI/MiniMax-H3/blob/main/docs/VIDEO_PROMPT_WRITING_GUIDE_base_en.md) is summarized in the [prompt guide](/tutorials/video/minimax/minimax-h3-prompt-guide).
## MiniMax H3 Image to Video (I2V)
Generate videos from an input image, with optional first/last-frame keyframes.
Open in Comfy Cloud
Download JSON or search "MiniMax H3 I2V" in Template Library
Download the default input image, or use your own image.

Place in ComfyUI/models/loras/. Used when turbo\_mode is enabled.

### Prompting tips
1. **Keyframes**: The `first_frame` and `last_frame` inputs are optional; the model generates the motion between them
2. **Prompt**: Describe the shots, motion, and the accompanying audio (dialogue, SFX, music) in one block
3. **Resolution**: H3's native canvas is a 768px short edge, which is 1344x768 at 16:9, and resolutions are rounded to a multiple of 32
4. **Duration**: The duration input snaps to the model's 17-frame-per-block (17k+5) grid at 24fps
5. **Turbo mode**: Enable `turbo_mode` on the MiniMax H3 node to switch to the turbo LoRA and generate in `turbo_steps` (default 8) instead of 20 steps. `turbo_model_strength` controls the LoRA strength (default 1.0).
The official base-mode [prompt writing guide](https://huggingface.co/MiniMaxAI/MiniMax-H3/blob/main/docs/VIDEO_PROMPT_WRITING_GUIDE_base_en.md) is summarized in the [prompt guide](/tutorials/video/minimax/minimax-h3-prompt-guide).
## MiniMax H3 Reference to Video (R2V)
Generate videos that lock in a character, style, motion, camera move, or voice from any mix of reference images, videos, and audio.
Open in Comfy Cloud
Download JSON or search "MiniMax H3 R2V" in Template Library
Character reference for the workflow, or use your own images.
Style and subject reference for the workflow, or use your own images.
