openai/sora-2/characters

Name: Sora 2 Characters
Author: OpenAI

Sora 2 Characters is OpenAI's image-to-video AI model. Bring static images to life with fluid animation, consistent character motion, and professional-grade video output.

Input

Video URL(string)

URL of an MP4 video (minimum 720p, max ~2.67:1 aspect ratio) to define the character. Videos exceeding 1080p are automatically scaled down. Non-standard aspect ratios are automatically padded to 16:9 (landscape) or 9:16 (portrait). Videos longer than 4 seconds are trimmed to the first 4 seconds.

Name(string)

Name for the character (1–80 characters). Refer to this name in prompts when using the character.

Input Schema

2 parameters · 0 required · 2 optional

Parameter	Type	Required	Description
`name`	string	Optional	Name for the character (1–80 characters). Refer to this name in prompts when using the character. · Min length: 1 · Max length: 80
`video`	string	Optional	URL of an MP4 video (minimum 720p, max ~2.67:1 aspect ratio) to define the character. Videos exceeding 1080p are automatically scaled down. Non-standard aspect ratios are automatically padded to 16:9 (landscape) or 9:16 (portrait). Videos longer than 4 seconds are trimmed to the first 4 seconds. · Min length: 1

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success
`error.type`	string	Machine-readable error type code
`error.message`	string	Human-readable error description

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response

API README

Sora 2 Characters

Sora 2 Characters is built for cinematic video generation, with this exact route focused on character-consistent creation. Sora 2 Characters is OpenAI's image-to-video AI model. Bring static images to life with fluid animation, consistent character motion, and professional-grade video output. It is designed for production workflows that need a clearly scoped media operation instead of a generic assistant response, preserving the supplied direction while returning an artifact ready for review, iteration, or downstream assembly.

The request surface keeps creative direction and delivery choices explicit through name, sync_mode, video_url, safety_tolerance. Teams can lock source material, describe the intended result, choose supported output controls, and rerun the same request structure across variations. This makes experiments easier to compare and larger pipelines easier to operate without hiding important decisions inside an opaque preset.

Highlights

Character-Consistent Creation. The openai/sora-2/characters route is dedicated to character-consistent creation, keeping inputs and outputs matched to this operation.
Coherent Motion And Scene Continuity. Within openai/sora-2/characters, documented prompt and media controls direct coherent motion and scene continuity while keeping the brief close to the result.
Directable Visual Storytelling. The openai/sora-2/characters result provides directable visual storytelling in a machine-consumable form for review and downstream production.
Route-specific control. For openai/sora-2/characters, documented controls include name, sync_mode, video_url, safety_tolerance, defining the supported variation space for this exact route.

When to Use

Scenario	Why it fits
Choose this route	When the deliverable is specifically character-consistent creation, not a neighboring generation or editing task.
Production iteration	When creative teams need repeatable coherent motion and scene continuity with an explicit request payload.
Automated pipelines	When directable visual storytelling must flow into review, storage, compositing, or publishing.
Controlled variations	When a stable brief should be rerun while changing only documented inputs.
Prototype to scale	When the same `openai/sora-2/characters` contract should serve a single experiment and a larger batch later.

Prompt Guide

Lead with the subject or source, then state the transformation, important spatial or temporal details, style, and finish. Supply only documented fields, keep media URLs reachable, and vary one control at a time when comparing outputs.
