# LumaRay32KeyframeNode - ComfyUI Built-in Node Documentation

> This node anchors a guide image to a specific position on the Luma Ray 3.2 output video timeline.

This node anchors a guide image to a specific position on the Luma Ray 3.2 output video timeline. Connect this node to the "keyframes" input of the Luma Ray 3.2 Keyframes to Video node, and chain several keyframes together by connecting the optional "keyframes" input.

| `position`  | How to place this image on the output video's timeline.        | DYNAMIC\_COMBO        | Yes      | "Fraction of duration (0.0-1.0)"<br />"Absolute time (seconds)" |
| `keyframes` | Optional earlier keyframes to chain with this one.             | LUMA\_RAY32\_KEYFRAME | No       | -                                                               |

### Fraction of duration (0.0-1.0) Inputs

| Parameter  | Description                                                                          | Data Type | Required | Range                   |
| ---------- | ------------------------------------------------------------------------------------ | --------- | -------- | ----------------------- |
| `fraction` | Where in the output video this image applies (0.0 = start, 1.0 = end). Default: 0.0. | FLOAT     | Yes      | 0.0 to 1.0 (step: 0.01) |

### Absolute time (seconds) Inputs

| Parameter | Description                                                                                | Data Type | Required | Range                   |

The `position` parameter determines which value is used to place the image on the timeline. Only the sub-parameter belonging to the selected option is shown and used: `fraction` for "Fraction of duration (0.0-1.0)" and `seconds` for "Absolute time (seconds)".

## Outputs

| Output Name | Description                                                                                   | Data Type             |
