Those tutorials show that. Remove the player as the focal point/character. The rest of the mechanics are there.
In simpler terms all you need to do is setup a spline. The documentation above details how to do that. Attach a camera to it, as in the video above. Make a timer for how long you want it to travel along the spline. Set it to reset as it finishes creating a loop that endlessly rotates around the level. Use level bp to possess the camera as it rides along the spline and use it to switch back to player when input is pressed.
That will get your desired results.
