Sora

Sora is a text-to-video model from OpenAI. Sora is a text-to-video model from OpenAI that quickly generates videos based on descriptive prompts entered by the user, as well as editing and expanding existing videos, with the following features:

• Powerful: generates videos up to 1 minute long with multiple resolutions and scales; generates detailed, coherent videos with complex scenes, multiple characters, and specific actions; mimics real-world physical rules with emerging simulation capabilities, such as generating videos with dynamic camera movements; and generates variable-sized images.
• Works uniquely: converts video data into spatial-temporal patches, trains networks to reduce the dimensionality of visual data, employs diffusion models and uses a Transformer architecture similar to the GPT model.
• Multiple applications: remix, re-cut, loop, blend, style presets.
• There are some limitations: it may be difficult to accurately model the physics of complex scenes, understand cause and effect relationships, and confuse spatial details.

The release of Sora is of great significance, as it has unique advantages in the field of video generation, provides more possibilities for creators, and may also bring some challenges and impacts, such as the proliferation of fake videos, affecting the film and television industry, and so on. The model is currently only available to ChatGPT Plus and Pro users.
