Matroska

Matroska is a special type of file format that can contain lots of different types of media, like video, audio, and subtitles. It's kind of like a container that holds all the different pieces of a movie or TV show together. Think of it like a lunchbox that can hold your sandwich, fruit, and a juice box all in one place.

The cool thing about matroska is that it can hold all these different types of media in one file, so you don't have to worry about lots of different files for a movie or TV show. Plus, it also allows you to add different types of audio tracks to the same video, like different languages or commentaries.

When you play a matroska file, your computer or device knows how to read all the different pieces inside and play them all together seamlessly. So, next time you watch a movie or TV show that's in a matroska file, remember that it's like a lunchbox that holds all the yummy stuff inside!
