How to blend camera from First Person Character to Sequencer?

I want to switch (for example by a trigger area) from first person camera to sequencer camera seamlessly. Even if the player is not at the very exact location, I want the camera to slide to the beginning position of the cinematic in a short time. I see and experience this in so many games but couldn’t find the way to make it. Maybe I don’t know which specific keywords to use to search but I hope I explained what’s in my mind clear.

Thanks! That was what I’ve been looking for.
