Realistic FPP Camera


I’m working on my game in FPP view. I created TPP project and attached camera to TPP character’s head. But I’m not satisfied enough. I think that camera’s movement is bad for my project. I want to create something more realistic and I come across that video on Youtube:

I want to add some head-bobing too, but I think that it can be easily done by matinee, right?

I’m not sure how I can do something like that. Maybe some blueprints stuff? Can you give me some advise?
