Sora

Sora is a text-to-video AI generation model developed by OpenAI that turns written descriptions into high-quality video content. First released in December 2024, with the latest Sora 2 version launched in September 2025, it represents a major technical breakthrough in AI video generation.

Key features:

• Text-to-video: Generate dynamic video content from written descriptions
• Image-to-video: Turn static images into dynamic video sequences
• Video editing: Extend or re-edit existing video content
• Audio sync: Automatically generate matching sound effects, music, and dialogue
• Multi-character scenes: Generate complex scenes containing multiple characters
• Style consistency: Maintain visual style and character consistency across shots

Sora is based on diffusion models and the Transformer architecture and can generate videos up to one minute long. It uses the recaptioning technique from DALL·E 3, improving its ability to understand and execute text instructions. The technology not only generates high-quality video but also includes advanced physics simulation, ensuring object motion conforms to real-world physical laws.

Use cases: In the creative industries, Sora helps creators quickly turn concepts into visual content, suitable for advertising production, social media content creation, and the development of educational training materials. For independent filmmakers and video bloggers, Sora provides a low-cost, professional-grade video production solution.

Safety features: All videos generated by Sora carry C2PA metadata watermarks, ensuring AI-generated content is traceable. The system also includes strict content filtering mechanisms to prevent generating harmful or misleading content.
