# LumaRay32KeyframeNode - ComfyUI Built-in Node Documentation

> Complete documentation for the LumaRay32KeyframeNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

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.

## Inputs

| Parameter   | Description                                                    | Data Type             | Required | Range                                                           |
| ----------- | -------------------------------------------------------------- | --------------------- | -------- | --------------------------------------------------------------- |
| `image`     | Guide image to place at the chosen moment of the output video. | IMAGE                 | Yes      | -                                                               |
| `position`  | How to place this image on the output video's timeline.        | 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       | -                                                               |

When "Fraction of duration (0.0-1.0)" is selected for the `position` parameter, you can specify a `fraction` value (default: 0.0, range: 0.0 to 1.0, step: 0.01) that determines where in the output video this image applies (0.0 = start, 1.0 = end).

When "Absolute time (seconds)" is selected for the `position` parameter, you can specify a `seconds` value (default: 0.0, range: 0.0 to 10.0, step: 0.1) that determines the time in seconds from the start of the output video where this image applies.

## Outputs

| Output Name | Description                                                                                   | Data Type             |
| ----------- | --------------------------------------------------------------------------------------------- | --------------------- |
| `keyframes` | A keyframe chain that includes the new keyframe combined with any optional earlier keyframes. | LUMA\_RAY32\_KEYFRAME |
