Variable bitrate

Okay kiddo, have you ever heard of a video or music file? They are like packages of information that have pictures or sound in them. And sometimes, these packages can have different sizes - some are small, while others are big.

Now, when these packages are uploaded on the internet, we need to make sure that they don't take up too much space or time to load. That's where variable bitrate comes in!

Variable bitrate is like a special setting that helps to adjust the size of these packages, making sure that they don't take up too much space or time to load. It works kind of like having a balloon that can get bigger or smaller, depending on how much air is needed.

So, if there is a lot of action happening in a video or music file, the variable bitrate will make the packages bigger so that all the details can be seen or heard clearly. But if there is less action or movement, the variable bitrate will make the packages smaller, so that they don't take up too much space or too long to load.

Overall, variable bitrate helps to make sure that videos or music files can be uploaded and watched without any problems, by adjusting the size of packages based on what's happening in those files.
