Sora
Resumen
Sora by OpenAI generates high-definition videos up to 20 seconds from text, with exceptional understanding of physics, lighting, and cinematic camera movements. Included in the ChatGPT Plus subscription.
Expert Review: Sora
Sora is OpenAI's text-to-video generation model, announced in February 2024 and broadly released to ChatGPT Plus and Pro subscribers in December 2024. Sora produces high-quality, temporally consistent video clips from text prompts and is considered one of the most technically advanced video generation systems publicly available.
Technical Capabilities
Sora generates videos up to 1080p resolution and up to 20 seconds in length — longer than most competing models. Its most notable technical achievement is temporal consistency: objects, surfaces, and characters maintain coherent appearance and position across frames, addressing one of the core failure modes of earlier video AI systems.
Prompting and Control
Sora accepts text prompts describing scenes, actions, camera movements, and visual styles. It also supports image-to-video extension and video editing through storyboard-style interfaces. The Storyboard feature allows users to design multi-scene narratives with distinct visual instructions per segment.
Quality vs. Access
In testing, Sora produces compelling results for simple, clearly-described scenes. Complex physics, human face preservation across motion, and very fast action sequences still exhibit imperfections. The model performs best on lifestyle, nature, and abstract artistic content. High-action sequences and precise human portraiture remain technically challenging.
Pricing and Limitations
Sora is available to ChatGPT Plus users with usage limits, and to Pro subscribers with higher generation allowances. Content policies restrict adult content, specific public figures, and potentially harmful material. Output is watermarked with C2PA metadata to indicate AI origin.
