Sora

As explained in Introduction to Generative AI, Second Edition

Sora is OpenAI's text-to-video generative model for producing realistic videos from textual descriptions.

Sora is OpenAI’s text-to-video generative model: it turns written descriptions into realistic videos. Unveiled in February 2024, it could produce videos lasting about a minute from short prompts. Public access followed in December 2024 for ChatGPT Pro and Plus subscribers. section 1.16

Its appeal is creative as well as technical. A prompt can describe an imagined scene, such as a papercraft coral reef filled with colorful fish and sea creatures. Yet generated footage may violate physics or contain spatial inconsistencies, so realistic appearance does not guarantee reliable movement or continuity. section 1.16

The Hardest Part

Washed Out’s “The Hardest Part” became the first official music video made with Sora. Directed by Paul Trillo, it combined dozens of AI-generated clips into a continuous, dreamlike zoom, allowing an idea previously difficult to execute to become a finished video. section 4.9
