AI that makes video
Video generators turn a text description or a photo into a short moving clip, and the results are now realistic enough to fool people.
01 · The idea
Most video generators work like image generators stretched over time. They start from visual noise and clean it up step by step, guided by your prompt, while keeping each frame consistent with the ones around it.
You can describe a scene, animate a still photo, or extend a clip. Many tools also add sound. Clips are usually short, and longer stories are built by joining pieces.
Flaws still appear. Watch for hands and text that shift, objects that melt into each other, physics that feels slightly wrong, and faces that change between shots.
Because fakes are getting harder to spot, some tools add labels or hidden credentials that record how a file was made. Treat shocking clips with care, look for the original source, and label your own AI videos.
02 · Think of it like this
It is like a flip-book artist who draws every page from memory. Each page looks good, but over many pages small details drift, like a button that changes colour.
