UE4 - How to create cinematics using the player's main camera?

Hi, Instead of making a cinematic, using spawned or in-location cameras, I want to use the main actor camera for seamless blend rotations and locations from the current transforms (changed by the player with the mouse) to the cinematic transforms, do you know a good video tutorial?

I can only find cut scene sequence tutorials where the first camera never blends with a player camera.

Please help.
