# MiniMaxH3ReferenceToVideo - ComfyUI Built-in Node Documentation

> MiniMax H3 Reference to Video creates the text conditioning and the empty video latent needed for MiniMax H3 reference-to-video generation.

MiniMax H3 Reference to Video creates the text conditioning and the empty video latent needed for MiniMax H3 reference-to-video generation. You provide a prompt plus optional reference images, videos, and audio clips, and the node encodes these references into tokens the model can use while generating. The prompt refers to the references with `<Picture i>`, `<Video k>`, and `<Audio j>` tags.

## Inputs

| Parameter          | Description                                                                                                                                                                                                                                                                                                                         | Data Type | Required | Range                  |
| ------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ---------------------- |
| `clip`             | CLIP model used to tokenize the prompt and encode the reference media into conditioning tokens.                                                                                                                                                                                                                                     | CLIP      | Yes      |                        |
| `vae`              | VAE used to encode reference images and reference video frames into latent space.                                                                                                                                                                                                                                                   | VAE       | Yes      |                        |

| `prompt`           | Text prompt for the video. Reference media can be addressed with `<Picture i>`, `<Video k>`, and `<Audio j>` tags (1-based per type). Supports multiline and dynamic prompts.                                                                                                                                                       | STRING    | Yes      |                        |
| `width`            | Width of the generated video in pixels (default: 1344).                                                                                                                                                                                                                                                                             | INT       | Yes      | 32 to 16384 (step 32)  |
| `height`           | Height of the generated video in pixels (default: 768).                                                                                                                                                                                                                                                                             | INT       | Yes      | 32 to 16384 (step 32)  |
| `length`           | Frame count at 24 fps; 124 = \~5s, trained range is \~124-362 (default: 124).                                                                                                                                                                                                                                                       | INT       | Yes      | 5 to 3600 (step 17)    |
| `ref_image_size`   | Reference image sizing mode. `match` scales each reference image down only, keeping the aspect ratio, to the generation's pixel area; `max` uses the reference pipeline's 2048px short edge for best identity fidelity. Reference tokens ride through every sampling step, so `max` can be several times slower (default: `match`). | COMBO     | Yes      | `"match"`<br />`"max"` |
| `ref_images`       | Optional reference images. Each image is downscaled to a 2048px short edge if larger and never upscaled. Multiple images can be provided.                                                                                                                                                                                           | IMAGE     | No       | 0 to 9                 |
| `ref_videos`       | Optional reference video frames at 24 fps (2-15s). Multiple videos can be provided.                                                                                                                                                                                                                                                 | IMAGE     | No       | 0 to 3                 |
| `ref_video_audios` | Optional soundtracks paired with reference videos by index; `ref_video_audio_N` is the soundtrack of the same-numbered `ref_video_N`.                                                                                                                                                                                               | AUDIO     | No       | 0 to 3                 |
| `ref_audios`       | Optional standalone reference audio clips.                                                                                                                                                                                                                                                                                          | AUDIO     | No       | 0 to 3                 |

Notes:

* The prompt refers to reference media with 1-based tags per type: `<Picture i>` for images, `<Video k>` for videos, and `<Audio j>` for audio. References are presented to the model in a fixed order: images, then videos (with each soundtrack's `<Audio j>` label right before its `<Video k>`), then standalone audio.
* Reference videos must contain at least 5 frames (\~0.2 seconds at 24 fps), otherwise the node raises an error. Video frames are also capped to the selected `length` and trimmed to a supported frame count.
