# MinimaxHailuo03FirstLastFrameNode - ComfyUI Built-in Node Documentation

> This node generates a video from a first frame image and, optionally, a last frame image using MiniMax H3 models.

This node generates a video from a first frame image and, optionally, a last frame image using MiniMax H3 models. The `model` selector changes which generation settings and constraints apply, and the aspect ratio of the generated video follows the supplied images.

## Inputs

### Common Inputs

| Parameter     | Description                                                                                                                                                     | Data Type      | Required | Range                                                          |
| ------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- | -------- | -------------------------------------------------------------- |
| `model`       | Model to use for video generation. Selecting a model reveals its model-specific settings below.                                                                 | DYNAMIC\_COMBO | Yes      | "MiniMax H3"<br />"MiniMax H3 Max"<br />"MiniMax H3 Max Turbo" |
| `first_frame` | First frame image for the video. The generated video follows the aspect ratio of this image.                                                                    | IMAGE          | Yes      | -                                                              |
| `last_frame`  | Optional last frame image for the video. When provided, the video is generated from the first frame toward this last frame.                                     | IMAGE          | No       | -                                                              |
| `seed`        | Random seed. The same request with the same seed gives similar, but not guaranteed identical, results. Includes a "control after generate" option. Default: 42. | INT            | Yes      | 0 to 4294967295                                                |
| `watermark`   | Whether to add an AIGC watermark to the video. This is an advanced parameter. Only supported by the `MiniMax H3` model. Default: False.                         | BOOLEAN        | Yes      | True<br />False                                                |

### MiniMax H3 Inputs

These settings are shown when `MiniMax H3` is selected in the `model` selector.

| Parameter    | Description                                                                           | Data Type | Required | Range            |
| ------------ | ------------------------------------------------------------------------------------- | --------- | -------- | ---------------- |
| `prompt`     | Text prompt for video generation. Must contain at least one non-whitespace character. | STRING    | Yes      | Multiline text   |
| `resolution` | Resolution of the output video.                                                       | COMBO     | Yes      | "768P"<br />"2K" |
| `duration`   | Duration of the output video in seconds. Default: 5.                                  | INT       | Yes      | 4 to 15          |

### MiniMax H3 Max and MiniMax H3 Max Turbo Inputs

These settings are shown when either `MiniMax H3 Max` or `MiniMax H3 Max Turbo` is selected in the `model` selector. Both models expose the same settings.

| Parameter               | Description                                                                                                  | Data Type | Required | Range                     |
| ----------------------- | ------------------------------------------------------------------------------------------------------------ | --------- | -------- | ------------------------- |
| `prompt`                | Text prompt for video generation. Must not be empty or whitespace-only, and is limited to 50,000 characters. | STRING    | Yes      | Multiline text            |
| `resolution`            | Resolution of the output video. Default: 768P.                                                               | COMBO     | Yes      | "480P"<br />"768P"        |
| `duration`              | Duration of the output video in seconds. Default: 5.                                                         | INT       | Yes      | 5 to 15                   |
| `prompt_expansion_mode` | How much effort is spent rewriting the prompt before generation. Default: balanced.                          | COMBO     | Yes      | "balanced"<br />"quality" |

**Notes on constraints:**

* The prompt must contain text: empty or whitespace-only prompts are rejected.
* Any supplied frame image must be at least 256 pixels wide and 256 pixels tall, with a width-to-height aspect ratio between 0.4 and 2.5 (approximately 2:5 to 5:2). This requirement applies to `first_frame` and, when provided, `last_frame`.
* When `last_frame` is omitted, the video is generated from the first frame only.
* The output video follows the aspect ratio of the supplied images.
* `watermark` is only supported by `MiniMax H3`. Enabling it with `MiniMax H3 Max` or `MiniMax H3 Max Turbo` raises an error.
* Duration ranges from 4 to 15 seconds for `MiniMax H3` and from 5 to 15 seconds for `MiniMax H3 Max` and `MiniMax H3 Max Turbo`.
