Abstract: A video encoding method and a video encoding apparatus include an input video signal divided into a plurality of temporally continuous scenes each including at least one frame. Statistical feature amounts are calculated for each of the scenes, encoded parameters are generated for each of the scenes based on the statistical feature amounts, and the input image signal is encoded using the encoded parameters.
