How do generative AI models like Sora create realistic videos?

Generative AI models like Sora create realistic videos by learning from lots of examples and then making new ones that look real.

Imagine you have a big box full of different kinds of clay, some smooth, some bumpy, some bright colors. Every time you want to make something new, you pick pieces from the box and shape them into what you want. Sora works kind of like that, but instead of clay, it uses videos.

First, Sora looks at many videos, like kids playing, animals running, or people talking. It learns all the little details: how things move, how colors change, and how sounds match what's happening on screen. This is like when you watch your friend draw a lot of pictures and start to notice patterns in their style.

Once Sora has learned from these examples, it can create its own videos. It picks pieces, or clues, from the videos it saw before and puts them together in smart ways. Like when you make a picture using parts of other pictures you've seen. The more it learns, the better it gets at making videos that look just like real life!
