# Flux3ImageToVideoNode - ComfyUI Built-in Node Documentation

> Flux 3 Image to Video animates 1 to 10 images with FLUX 3.

Flux 3 Image to Video animates 1 to 10 images with FLUX 3. Each image becomes a frame of the clip: one image opens it, two morph from the first to the second, and more are spread across it or pinned to times you choose.

## Inputs

| Parameter          | Description                                                                                                                                                                 | Data Type      | Required | Range                                                  |
| ------------------ | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------- | -------- | ------------------------------------------------------ |
| `prompt`           | How the scene should move and sound; the prompt is interpreted and expanded before generation. Must contain at least one character.                                         | STRING         | Yes      | Multiline text (default: empty)                        |
| `keyframes`        | 1 to 10 images, in playback order. Minimum 256x256 pixels each. Growable input: connect images as `image_1`, `image_2`, and so on.                                          | IMAGE          | Yes      | 1 to 10 images                                         |
| `placement`        | "spread across the clip" lets FLUX 3 place the images (one opens the clip, two become its start and end); "at times" pins every image to a second you choose.               | DYNAMIC\_COMBO | Yes      | `"spread across the clip"` (default)<br />`"at times"` |
| `times`            | One time in seconds per image, comma-separated and increasing, e.g. "0, 2.5, 5". Only appears when `placement` is "at times"; one time is required for each keyframe image. | STRING         | No       | Comma-separated seconds (default: "0")                 |
| `aspect_ratio`     | Output aspect ratio. "auto" picks one from the prompt and inputs.                                                                                                           | COMBO          | Yes      | `"auto"` (default)<br />other available aspect ratios  |
| `duration`         | Clip length in seconds. "auto" fits the length to the content.                                                                                                              | COMBO          | Yes      | `"auto"` (default)<br />other available durations      |
| `resolution`       | Output resolution.                                                                                                                                                          | COMBO          | Yes      | `"720p"` (default)<br />`"1080p"`                      |
| `generate_audio`   | Generate synchronized audio (ambient, speech, effects). Off produces a video with no audio track.                                                                           | BOOLEAN        | Yes      | true / false (default: true)                           |
| `safety_tolerance` | Moderation tolerance, 0 is the strictest. Requests that send images or video are capped at 2 whatever you set here.                                                         | INT            | Yes      | 0 to 4 (default: 2, advanced setting)                  |
| `seed`             | Seed to determine if node should re-run; FLUX 3 picks its own seed, so actual results are nondeterministic regardless of this value.                                        | INT            | Yes      | 0 to 4294967295 (default: 42, control-after-generate)  |

Note: `keyframes` must contain at least one image; the node raises an error if none are connected. Each keyframe image must be at least 256x256 pixels and its aspect ratio cannot be more extreme than 64:1.

When `placement` is "spread across the clip" and 3 or more keyframes are connected, `duration` must be set to an explicit value, not "auto"; otherwise the node raises an error.

When `placement` is "at times", `times` must provide one time in seconds per image. The times must increase, cannot be negative, and the last time cannot be past the end of the clip (up to 20 seconds when `duration` is "auto").

Because this node sends images, `safety_tolerance` is capped at 2 regardless of the value you set.
