Sora operates as a sophisticated diffusion model, initiating video creation from static noise and progressively refining it into coherent scenes matching user input. This process, an adaptation of OpenAI's DALL-E 3, processes video in latent space by denoising 3D 'patches' to interpret abstract concepts, emotions, and contextual cues from text, ensuring videos resonate with intended moods. Users can provide detailed text prompts, which Sora translates into videos up to 60 seconds, from 480p to 1080p. These prompts can describe intricate scenes, diverse characters with expressive emotions, and complex camera movements, adhering to realistic physics. Sora also animates still images into engaging video sequences. For existing content, video remixing and blending allow enhancement and modification with new elements or styles. Plus and Pro desktop users benefit from a storyboarding option to plan scenes. Videos can be generated in various artistic styles: cinematic, animated, photorealistic, or surreal, for tailored outputs. The model excels in scene composition, generating interactions with multiple elements while maintaining spatial awareness. Sora 2 introduced synchronized dialogue and sound effects, automatically adding music, sound effects, and speech. A unique 'Characters' feature allows users to cast themselves and friends into videos, with control over likeness usage. Robust safety measures include visible watermarks and C2PA metadata indicating AI provenance. A likeness misuse filter prevents unauthorized depiction of real people, and parental controls are available in ChatGPT. Input prompts are monitored to block inappropriate content. Access is integrated into ChatGPT subscription plans, with Plus and Pro subscribers receiving generous daily allowances, and a limited allowance for free ChatGPT accounts as a teaser.
