Beta

This model is currently in public testing. Not everyone has access, and API requests may also be unstable.

Overview

Sora 2 Pro is OpenAI’s premium video generation model, offering higher quality output compared to the standard Sora 2 model. It’s capable of creating richly detailed, dynamic clips from natural language prompts or image references.

Key Features

• Higher quality video generation than Sora 2
• Text-to-video and image-to-video generation
• Support for more resolution options including portrait and landscape formats
• Ideal for professional content creation

Supported Resolutions

Size	Aspect Ratio	Use Case
720x1280	9:16	Vertical/Portrait (mobile, social media)
1280x720	16:9	Horizontal/Landscape (standard video)
1024x1792	9:16	Tall Portrait (extended vertical)
1792x1024	16:9	Wide Landscape (cinematic)

Duration Options

Videos can be generated in three duration options:

• 4 seconds: Quick clips (default)
• 8 seconds: Standard duration
• 12 seconds: Extended clips

Effective Prompting

For best results, describe shot type, subject, action, setting, and lighting. For example:

• “Wide shot of a child flying a red kite in a grassy park, golden hour sunlight, camera slowly pans upward.”
• “Close-up of a steaming coffee cup on a wooden table, morning light through blinds, soft depth of field.”

This level of specificity helps the model produce consistent results without inventing unwanted details.

Content Restrictions

The API enforces several content restrictions:

• Only content suitable for audiences under 18
• Copyrighted characters and copyrighted music will be rejected
• Real people—including public figures—cannot be generated
• Input images with faces of humans are currently rejected
