Abstract

A video encoding method, a video encoding apparatus, a video decoding method, and a video decoding apparatus, the video encoding method including producing a fast transform matrix based on a transform matrix which is used for frequency transformation on a predetermined-size block; producing a transformed block by transforming the predetermined-size block by using the fast transform matrix; and performing scaling with respect to the transformed block to correct a difference between the transform matrix used for the frequency transformation and the fast transform matrix.
