Compared with previous AI-generated video tools, Sora can not only generate videos of up to one minute based on a few words of text description, but can also understand and simulate the dynamics of the real world and generate high-definition videos that are more in line with our cognitive laws. video.
It is difficult to intuitively feel the shock of Sora from just the text introduction. Ayan introduces its masterpiece here to let everyone feel it:
It can be seen that the amount of information displayed in this short paragraph is huge, both the characters and the street scenes are full of details, and the camera switching is also very smooth and natural.
In addition to this video, OpenAI has also released other videos generated based on different text prompts on its official website.

Why is it called Sora?
As the first video generation Al model Sora launched by OpenAl, its name actually comes from the Japanese Chinese character "empty" (can be written as そら, or sora).
In Japanese, "sora" has many meanings:
① Sky
As the literal meaning indicates, the most direct meaning of "empty" is the sky.
Example: The sky is turning white.
(It's already dark)
Translation: The sky is getting whiter.
②(distant) place
The vastness of the sky always makes people imagine, and perhaps it is this imagination that gives the Japanese word "empty" the symbolic meaning of the distant shore.
Example: A foreign sky.
(The sky is blue)
Translation: A foreign country.
③ Mood
In addition to the outward imagination of the vastness of heaven and earth, "empty" is also based on the inward imagination, deriving the meaning of state of mind.
Example: absent-minded.
(Uwa no sora)
Translation: Absent-minded.
It can be seen that Sora not only refers to the "sky" in the literal sense, but also symbolizes the vast world and the infinite possibilities of "as big as the heart is, as big as the stage".
OpenAl chose the name Sora, perhaps hoping that it would raise the upper limit of human video creation and bring new possibilities to all walks of life.
