AI video generation
영상 생성 AI
AI that makes a short moving video from a description in words or from a single image.
Overview
Write "a cat walking down a snowy alley," and a short video appears. It extends image-making technology along the time axis, creating many frames together so that the scenes before and after connect naturally. Some tools also create sound and dialogue that fit the video.
The limits are still clear. As a video gets longer, a character's look may change, objects may suddenly vanish, or scenes that make no sense may appear, such as water flowing backward. There is also growing worry that it can be misused for fake videos showing things real people never said or did.
An everyday example
If you draw slightly different pictures in the corner of a notebook and flip the pages, they seem to move. Video generation draws hundreds of such pictures at once, so that they fit together.
Why it matters
The cost and time of making ads, trailers and short videos are dropping a lot. At the same time, even a video you saw with your own eyes is harder to take at face value, so labeling the source and spotting fakes have become important.
