A is a video encoder includes a data storage for storing a prediction residual, the number of bits of the prediction residual, and a motion vector in each encoded picture, as well as a motion compensator for selecting a motion predict mode from an output of the data storage. The video encoder of the present is intended to solve the conventional problem in which the number of bits in estimation of the number of bits used to select a motion predict mode of the video encoder increases, since the conventional residual bits estimating function is not determined uniquely and the number of bits that depends on the congeniality of each input picture is not always obtained accurately.
