CinemachineBrain is the link between the Unity Camera and the Cinemachine Virtual Cameras in the scene. It monitors the priority stack to choose the current Virtual Camera, and blend with another if necessary. Finally and most importantly, it applies the Virtual Camera state to the attached Unity Camera. The CinemachineBrain is also the place where rules for blending between virtual cameras are defined. Camera blending is an interpolation over time of one virtual camera position and state to another. If you think of virtual cameras as cameramen, then blending is a little like one cameraman smoothly passing the camera to another cameraman. You can specify the time over which to blend, as well as the blend curve shape. Note that a camera cut is just a zero-time blend.
