Cutscene Bands at the top and bottom

How would i go about making a cutscene with the black bands to make it widescreen that will physically move out after the cutscene? is there a better way than to make a black plane that cuts off the bottom and top of the camera? Thanks.

You could probably accomplish this by modifying the camera viewport via scripting (that is, interpolating from one viewport rect to another over the desired time interval). Note that you might need another camera 'behind' the cutscene camera rendering nothing but a black background.
