Playing cinematic videos.

I’m currently working on a 2D platformer, and it’s coming along really well. One of the options available is to travel from one place to another through a plane. When the character enters the plane, I wanted a cinematic to play of the character just sitting down for 4 seconds inside the plane.
This is more or less what I want:

I’m pretty sure the solution is extremely simple, but I’m kind of new with Unreal and I’m learning little by little everything I need to finish this game.
If any of you knows the step by step I need to follow to introduce a cinematic (either if it’s with a flipbook or a .mp4 file and how to introduce it), please let me know. Thanks you!
