Okay kiddo, so you know how when you record a video on your tablet or phone, you see yourself moving around and talking? That's called a "human video." It's when people make a video of themselves doing different things, like dancing, singing, or just talking to the camera.
Now, imagine that instead of just one person in the video, there are lots of people all doing different things together. They might be dancing in a big group, or acting out a scene from a movie. That's called a "group human video."
Sometimes, people will even make a human video where they all dress up in costumes and act out a whole story, like a mini movie. It's a really fun way for people to work together and be creative.
There are even competitions where people can show off their human videos and compete against other groups to see who made the best one. It's like a big talent show, but with videos instead of live performances.
So you see, a human video is just people making a video of themselves doing different things, and it can be really fun and creative!
