# Luma Image to Video

Generates videos synchronously based on a text prompt and optional starting/ending images. This node uses the Luma API to create videos, allowing you to define the video's content through a prompt and optionally specify the first and/or last frame to control the video's structure.

## Inputs

| Parameter | Description | Data Type | Required | Range |
|-----------|-------------|-----------|----------|-------|
| `prompt` | Prompt for the video generation (default: "") | STRING | Yes | - |
| `model` | Selects the video generation model from available Luma models | COMBO | Yes | `"ray-1-6"`<br>`"ray-2"` |
| `resolution` | Output resolution for the generated video (default: "540p"). This parameter is ignored when using the `ray-1-6` model. | COMBO | Yes | `"540p"`<br>`"720p"`<br>`"1080p"`<br>`"4k"` |
| `duration` | Duration of the generated video. This parameter is ignored when using the `ray-1-6` model. | COMBO | Yes | `"5s"`<br>`"9s"` |
| `loop` | Whether the generated video should loop (default: False) | BOOLEAN | Yes | - |
| `seed` | Seed to determine if node should re-run; actual results are nondeterministic regardless of seed. (default: 0) | INT | Yes | 0 to 18446744073709551615 |
| `first_image` | First frame of generated video. (optional) | IMAGE | No | - |
| `last_image` | Last frame of generated video. (optional) | IMAGE | No | - |
| `luma_concepts` | Optional Camera Concepts to dictate camera motion via the Luma Concepts node. (optional) | CUSTOM | No | - |

**Note:** At least one of `first_image` or `last_image` must be provided. The node will raise an exception if both are missing. The `resolution` and `duration` parameters are ignored when the `model` is set to `ray-1-6`.

## Outputs

| Output Name | Description | Data Type |
|-------------|-------------|-----------|
| `output` | The generated video file | VIDEO |
