Abstract: A moving image encoding apparatus executes moving image encoding of a syntax element relating to a moving image signal VS to form an encoded bitstream CVBS. Padding processing of adding padding processing data PD to the moving image signal VS is executed prior to the moving image encoding.

In the case that the encoded block belongs to the former, an encoded bitstream having a large code amount is formed. In the case where the encoded block belongs to the latter, an encoded bitstream having a small code amount is formed.
