A video keying processing device is provided which comprises memory configured to store data and a processor configured to determine, which pixel portions, in a YUV color space of a first video comprising a foreground object and a background color, represent the foreground object and the background color of the first video. The processor is also configured to, for each pixel portion of the first video determined to represent the foreground object and the background color, convert YUV values of the pixel portion to red-green-blue (RGB) color component value and determine a blended display value for each RGB color component of the pixel portion based on a blending factor. The processor is also configured to generate a composite video for display using the blended display values of each pixel portion determined to represent the foreground object and the background color.
