# ViduMultiFrameVideoNode - ComfyUI Built-in Node Documentation

> This node generates a video by creating transitions between multiple keyframes.

This node generates a video by creating transitions between multiple keyframes. It starts from an initial image and animates through a sequence of user-defined end images and prompts, producing a single video file as output.

## Inputs

### Common Inputs

| Parameter     | Description                                                                                                     | Data Type      | Required | Range                                                              |
| ------------- | --------------------------------------------------------------------------------------------------------------- | -------------- | -------- | ------------------------------------------------------------------ |
| `model`       | The Vidu model to use for video generation.                                                                     | COMBO          | Yes      | "viduq2-pro"<br />"viduq2-turbo"                                   |
| `start_image` | The starting frame image. Aspect ratio must be between 1:4 and 4:1.                                             | IMAGE          | Yes      | Aspect ratio 1:4 to 4:1                                            |
| `seed`        | A seed value for random number generation to ensure reproducible results (default: 1).                          | INT            | Yes      | 0 to 2147483647                                                    |
| `resolution`  | The resolution of the output video.                                                                             | COMBO          | Yes      | "720p"<br />"1080p"                                                |
| `frames`      | Number of keyframe transitions (2-9). Selecting a value dynamically reveals the required inputs for each frame. | DYNAMIC\_COMBO | Yes      | "2"<br />"3"<br />"4"<br />"5"<br />"6"<br />"7"<br />"8"<br />"9" |

### Frame Inputs (shared by all frame count options)

When `frames` is set to a number, the following three inputs are shown for each frame `i` from 1 to that number. For example, choosing "3" adds `prompt1` / `end_image1` / `duration1`, `prompt2` / `end_image2` / `duration2`, and `prompt3` / `end_image3` / `duration3`.

| Parameter      | Description                                                                           | Data Type | Required | Range                   |
| -------------- | ------------------------------------------------------------------------------------- | --------- | -------- | ----------------------- |
| `prompt{i}`    | Text prompt for frame \{i} transition. Multiline text field. Maximum 2000 characters. | STRING    | Yes      | Up to 2000 characters   |
| `end_image{i}` | End frame image for segment \{i}. Aspect ratio must be between 1:4 and 4:1.           | IMAGE     | Yes      | Aspect ratio 1:4 to 4:1 |
| `duration{i}`  | Duration for segment \{i} in seconds (default: 4).                                    | INT       | Yes      | 2 to 7                  |

**Notes:**

* All inputs are required. `seed` has a default value but is still a required input.
* `start_image` and every `end_image{i}` must have an aspect ratio between 1:4 and 4:1.
* Every `prompt{i}` has a maximum length of 2000 characters.
* Every `duration{i}` must be between 2 and 7 seconds.
