	'''BlankClip''' produces a solid color video clip with silent audio. The ''clip'' passed as an argument is used as a ''template'' - for frame rate, image size, and so on, but the template is optional. You can specify as many clip properties explicitly as you wish. By default, '''BlankClip''' will produce a pitch-black 10 second clip; 24 fps, 640x480, RGB32, with 16 bit, 44100 Hz, mono, silent audio.
