# Flux3VideoContinuationNode - ComfyUI Built-in Node Documentation

> Complete documentation for the Flux3VideoContinuationNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node continues an existing video clip with FLUX 3, so the new clip carries on from the final frames of the video you provide. It uploads your source clip, sends the prompt and settings to the generation service, and returns the resulting continuation video once it is ready.

## Inputs

| Parameter          | Description                                                                                                                                                            | Data Type | Required | Range                                           |
| ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | ----------------------------------------------- |
| `video`            | The clip to continue.                                                                                                                                                  | VIDEO     | Yes      | Single video clip                               |
| `prompt`           | What the continuation should show; the prompt is interpreted and expanded before generation. (default: "")                                                             | STRING    | Yes      | Non-empty text (minimum 1 character)            |
| `aspect_ratio`     | Output aspect ratio. 'auto' picks one from the prompt and inputs. (default: "auto")                                                                                    | STRING    | Yes      | Multiple predefined options (default: "auto")   |
| `duration`         | Clip length in seconds. 'auto' fits the length to the content. (default: "auto")                                                                                       | STRING    | Yes      | "auto" (default)<br />Numeric values in seconds |
| `resolution`       | Output resolution. (default: "720p")                                                                                                                                   | STRING    | Yes      | Multiple predefined options (default: "720p")   |
| `generate_audio`   | Generate synchronized audio (ambient, speech, effects). Off produces a video with no audio track. (default: true)                                                      | BOOLEAN   | Yes      | true<br />false                                 |
| `safety_tolerance` | Moderation tolerance, 0 is the strictest. Requests that send images or video are capped at 2 whatever you set here. (advanced parameter, default: 2)                   | INT       | Yes      | 0 - 4 (effective maximum: 2 for video requests) |
| `seed`             | Seed to determine if node should re-run; FLUX 3 picks its own seed, so actual results are nondeterministic regardless of this value. (advanced parameter, default: 42) | INT       | Yes      | 0 - 4294967295 (0xFFFFFFFF)                     |

### Notes

* `prompt` must contain at least one character, otherwise generation fails. Although the field defaults to an empty string, a non-empty prompt is required to run the node.
* `safety_tolerance` accepts any value from 0 to 4, but since this node sends a video to the API, the effective tolerance is capped at 2 regardless of the selected value.
* When `duration` is set to a number, it is converted to an integer number of seconds. The special value "auto" lets the service fit the length to the content.
* The exact option lists for `aspect_ratio`, `duration`, and `resolution` are defined internally by the node. Resolution options include at least "720p" (the default) and "1080p", which uses a different pricing rate.
* Authentication and node identification fields (`auth_token_comfy_org`, `api_key_comfy_org`, `unique_id`) are hidden and handled automatically by the platform.
