Overview

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

Authentication

Request Parameters

model · string · default: "sora-2" · required

Video generation model name

Supported models:

• sora-2 - Standard version
• sora-2-pro - Professional version (higher quality)
• sora-2-vip - VIP version, higher priority

timestamps · string · required

Character appearance timestamp range

Unit is seconds, format is "start_second,end_second"

Constraints:

• Time range difference minimum: 1 second
• Time range difference maximum: 3 seconds

Example: "1,3" means the character appearing from second 1 to second 3 in the video

url · string

Video URL containing the character to extract

Requirements:

• Video must contain audio
• Video must contain identifiable characters

Note: Either url or from_task required

Example: "https://example.com/my-video.mp4"

from_task · string

Task ID of a previously generated video

Create character from an existing video generation task

Note: Either url or from_task required

Example: "task_01KBYT59JDHB4A3KDDR9N9JVWP"

Response Fields

id · string

Unique task identifier for querying character creation status

After completion, this character task ID can be used in video generation via the character_url parameter

object · string

Object type, always generation.task

model · string

Model name used

status · string

Task status:

• queued - Queued for processing
• in_progress - Processing
• completed - Successfully completed
• failed - Failed

progress · integer

Task progress percentage (0-100)

created_at · integer

Task creation time (Unix timestamp)

completed_at · integer

Task completion time (Unix timestamp, only available after completion)

result · object

Character creation result (only available after completion)

Contains created character information such as character ID, name, profile picture, etc.

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 Status

   Use the Query Video Task Status API to poll task progress

4. Use Character in Video Generation

   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
