A multi-camera video production is a great way to provide multiple angles of an event when a single view just isn't enough.  We can do this one of two ways.   The first method is to roll tape and do a post production edit and switch the camera angles.   The second method is to use a switcher on site and mix the camera's on the fly.   This method is primarly used for image magnification for spectators during sporting events, concerts & plays in conjunction with projectors and screens.
