Sora 2 is OpenAI's latest video and audio generation model, capable of directly outputting movie-level realistic videos based on text prompts. It features complete audio-visual capabilities such as multi-camera narrative, environmental and physical simulation, and synchronized sound effects. Users can also inject their own appearance and voice into characters through selfies or voice recordings, enabling "everyone to act in movies". In terms of real-world simulation, Sora 2 can precisely reproduce natural phenomena such as water, fabric, and gravity by following the laws of object movement, material properties, light and shadow, and dynamics, making character and camera movements highly credible.
