A video encoder/decoder device, method, and computer program product combine to enhance entropy encoding by using different calculation approaches for assessing costs of using different encoding modes for a video encoding. Moreover, frames in a sequence, and/or sub-frames within a frame may have lowest cost coding modes selected using different cost calculation approaches. One exemplary cost calculation is SAD and another is SSD. A net effect is better subjective video quality for a given bitrate, with reduced encoder complexity, especially when recognizing the lesser amount of computational resources required to support SAD as opposed to SSD.
