Sora 2 Image-to-Video

Sora 2 API Overview

Sora 2 is OpenAI’s next-generation image-to-video AI model designed to generate cinematic, high-fidelity videos from simple text prompts or image references, with synchronized audio and realistic physics, making it a versatile powerhouse for prompt-to-film content creation.

Technical Specifications

• Temporal Consistency: Improved frame-to-frame stability to reduce flickering and object disappearance
• Aspect ratio: 16:9, 9:16
• Physics Modeling: Advanced physics accuracy including gravity, collisions, fluid dynamics, and realistic motion behaviors (e.g., gymnastic movements, object interactions)
• Audio Synthesis: Supports spatial audio, with frame-perfect synchronization to video actions
• Clip Length: Generates videos typically up to 30–60 seconds per prompt
• Model Efficiency: Applies spatiotemporal autoencoders to compress latent video space, boosting generation speed and preserving details
• Safety & Governance: Includes watermarking, provenance metadata, and content moderation for ethical use
• Content Restrictions: Photorealistic person images are restricted in inputs; video uploads moderated for compliance

Key Features
