OpenAI前几天发布了一个新的模型：Sora，这是一款全新的影片生成AI工具，一款创新性文本到视频的生成模型，可以根据用户提供的文本指令自动生成高质量的视频。目前Sora还在内测阶段，这篇文章ChatGPT中文网先给大家介绍下Sora模型，以及它强大的文字转视频能力。
一、Sora是什么

Sora是OpenAI发布的最新的文字转视频模型，用户只需要提供简单的描述性文字，就可以生成长达60秒的视频。Sora生成的视频呈现出专业摄影师级别的效果，包括详细的场景、镜头变化、光影色彩转变以及纹理结构的变化。
二、Sora效果展示
Sora怎么样呢？OpenAI在官网放了一些Sora模型的作品，ChatGPT中文网摘取了其中3个给大家看下。
Sora生成的视频示例1：
提示词：A stylish woman walks down a Tokyo street filled with warm glowing neon and animated city signage. She wears a black leather jacket, a long red dress, and black boots, and carries a black purse. She wears sunglasses and red lipstick. She walks confidently and casually. The street is damp and reflective, creating a mirror effect of the colorful lights. Many pedestrians walk about.

Sora生成的视频示例2：
提示词：Historical footage of California during the gold rush.

Sora生成的视频示例3：
提示词：The camera follows behind a white vintage SUV with a black roof rack as it speeds up a steep dirt road surrounded by pine trees on a steep mountain slope, dust kicks up from it’s tires, the sunlight shines on the SUV as it speeds along the dirt road, casting a warm glow over the scene. The dirt road curves gently into the distance, with no other cars or vehicles in sight. The trees on either side of the road are redwoods, with patches of greenery scattered throughout. The car is seen from the rear following the curve with ease, making it seem as if it is on a rugged drive through the rugged terrain. The dirt road itself is surrounded by steep hills and mountains, with a clear blue sky above with wispy clouds.
