A media clip is like a short little video or sound recording that you can watch or listen to. It's usually just a small part of a bigger video or recording that someone has made. Think of it like a piece of pizza - the media clip is just one tiny slice of the whole pizza. Sometimes people use media clips to show a really funny or interesting part of a video or recording, without having to show the whole thing. So instead of watching a whole 10 minute video, you can just watch a 30 second clip that shows the best part.
