ELI5: Explain Like I'm 5

Video quality

Imagine you have a toy that shows pictures on a screen, and you can make it bigger or smaller to see the pictures better. Video quality is kind of like that toy, but instead of pictures, it shows a moving picture called a video.

When you watch a video, the screen shows lots of tiny dots called pixels. The more pixels there are, the clearer the video looks, and the better the video quality is. Just like when you draw a picture, the more dots you use, the more detailed and clearer your picture will be.

Video quality can also depend on how fast the video moves. Sometimes videos can look blurry or not sharp because they are moving too fast, and the pixels can't keep up. So, if the video is moving faster than the pixels can change, it might look not so great.

There are different ways to save and show videos, and that can also affect the quality. For example, some videos are recorded in high definition (HD) or ultra-high definition (UHD), which means they have lots and lots of pixels to show very clear and detailed pictures.

In summary, video quality is how clear and detailed a video looks, based on the number of pixels on the screen and how fast the video is moving. The more pixels a video has and the slower it moves, the higher the quality.
