# Sora2 Create Character

> Extract characters from video for subsequent video generation

## 개요

The Sora2 character creation feature allows you to extract characters from existing videos. Once created, you can reuse the character in subsequent video generations to maintain character consistency.

<Note>
  **Important:**

  * Video must contain **audio** and **identifiable characters**
  * Time range limit: **minimum 1 second, maximum 3 seconds**
  * Either `url` or `from_task` is required - must provide one
  * `prompt` parameter is **not required** in this mode
  * After creation, the character task ID can be used for subsequent video generation
</Note>

  Bearer Token authentication

  ```
  Authorization: Bearer YOUR_API_KEY
  ```

## Usage Flow

<Steps>
  <Step title="Submit Character Creation Request">
    Call this API with a video URL or existing task ID containing the character, along with the time range
  </Step>

  <Step title="Get Task ID">
    API returns task ID with status `queued` or `in_progress`
  </Step>

  <Step title="Query Task 상태">
    Use the [Query Video Task 상태](../../tasks/video-status) API to poll task progress
  </Step>

  <Step title="Use Character in 비디오 생성">
    After character creation completes, use `character_url` parameter to reference the character task ID in subsequent video generation
  </Step>
</Steps>

## Best Practices

1. **Choose Clear Character Segments**: Select 1-3 second segments where character features are most prominent
2. **Ensure Video Quality**: High-definition video allows better character feature extraction
3. **Include Audio**: Video must contain an audio track
4. **Avoid Multiple Characters**: The selected time range should ideally contain only one main character
