Sora 2 is a cloud-based AI video and audio generation system that converts text prompts or images into realistic, cinematic videos. It models physics-true motion (gravity, buoyancy, momentum), generates native audio and lip-synced dialogue, and renders continuous 20-second clips without manual stitching. The model preserves multi-shot world coherence to maintain consistent characters and environments across shots, supports personal cameos for face and voice insertion, and offers multi-style rendering from photorealistic to stylized art. Sora 2 emphasizes creative control over aspect ratio, composition, and motion dynamics, enabling fast iteration for ads, storytelling, and content prototyping.
