| ---------------------- | --------- | -------- | ---------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `reference_video_urls` | string\[] | Yes      | -          | Publicly reachable source video URL. Must contain exactly one URL. Uploaded source videos must meet the limits below.                                                                                                                                                |
| `prompt`               | string    | Yes      | -          | Edit instruction. Use `@Video1` to refer to the source video and `@ImageN`/`@CharacterN` for extra references.                                                                                                                                                       |
| `reference_image_urls` | string\[] | No       | -          | Publicly reachable image URLs used as edit references. They count toward the total reference limit.                                                                                                                                                                  |
| `reference_characters` | array     | No       | -          | Character references for the edit. Max 3 character items. Each character may include 1-10 `image_urls`. Supports per-character `voice` or `custom_voice`. See [available voices](/api-reference/resources#get-google-veo-voices).                                    |
| `seed`                 | integer   | No       | Random     | Seed sent with the edit request. If omitted, a seed is generated automatically and returned when available.                                                                                                                                                          |
| `resolution`           | string    | No       | `"720p"`   | Output resolution. Allowed: `"360p"`, `"720p"`, `"1080p"`, `"4k"`. `"360p"` and `"720p"` generate natively — 360p at half the 720p price. With `"1080p"` or `"4k"`, the edited video generates at 720p and is upscaled as part of the same task before it completes. |
| `start_frame`          | integer   | No       | `0`        | First source frame index included in the edit range.                                                                                                                                                                                                                 |
| `end_frame`            | integer   | No       | Source end | Last source frame index included in the edit range. If omitted, the service uses the detected final frame when available.                                                                                                                                            |
| `allow_audio_filtered` | boolean   | No       | `false`    | When `true`, the generation runs without audio instead of failing when the audio track is filtered.                                                                                                                                                                  |
| `nsfw_check`           | boolean   | No       | `true`     | Check uploaded media inputs for NSFW content                                                                                                                                                                                                                         |

## Limits

| Limit                                      | Value            |
| ------------------------------------------ | ---------------- |
| Video references                           | 1                |

## Character References

Character references work exactly as on [Gemini Omni Flash Video Edit](/models/video/google/gemini-omni-flash-video-edit#character-references): objects with `image_urls` (1-10 images), optional `name`, `description`, and a per-character preset `voice` or tuned `custom_voice`.

## Example — 360p Edit

```bash theme={null}
curl -X POST https://api.unifically.com/v1/tasks \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "google/gemini-omni-flash-1.1-video-edit",
    "input": {
      "reference_video_urls": [
        "https://example.com/source-video.mp4"
      ],
      "prompt": "Make @Video1 look like it was filmed underwater.",
      "resolution": "360p"
    }
  }'
```

## Prompt References

| Token                        | Refers to                              |
| ---------------------------- | -------------------------------------- |
| `@Video1`                    | The source video for edit requests     |
| `@Image1`, `@Image2`         | Items from `reference_image_urls` only |
| `@Character1`, `@Character2` | Items from `reference_characters` only |

## Rejected Combinations

The same rules as [Gemini Omni Flash Video Edit](/models/video/google/gemini-omni-flash-video-edit#rejected-combinations) apply: exactly one source video URL, max 7 total references, characters as objects with `image_urls`, and a forward-moving frame range.
