概要

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.
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

Usage Flow

1

Submit Character Creation Request

Call this API with a video URL or existing task ID containing the character, along with the time range
2

Get Task ID

API returns task ID with status queued or in_progress
3

Query Task ステータス

Use the Query Video Task ステータス API to poll task progress
4

Use Character in 動画生成

After character creation completes, use character_url parameter to reference the character task ID in subsequent video generation

​
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
