How to create cutscenes with moving animations

Hello everyone, I am very very new to using unreal engine and game development in general and I have seen the ability to make full cutscenes with moving animations and such. For example a cutscene with an explosion and a person playing a running animation moving away while also the ability to move individual bones every frame to create a cutscene in the 3d world, what is this called and are there any tutorials I can use?

Sequencer is your answer!
tThere are a lot of sequencer tutorials in youtube. Just look for unreal engine sequencer.
