Moving image encoding apparatus, moving image encoding method, and program

摘要

A moving image encoding apparatus includes a first-step encoding section for executing a plurality of times first-step encoding by use of different quantization control variables; a code-amount estimation section for estimating, for all the quantization control variables, an amount of codes generated for each frame by making use of a plurality of results of the encoding; a code-amount allocation section for allocating an amount of codes for each frame on the basis of results of the estimation; and a second-step encoding section for executing second-step encoding on the basis of the amount of codes allocated to each frame. The first-step encoding section changes the number of times of execution of the encoding in accordance with the attribute of each frame, and omits a portion of processes contained in the coding process in the second and subsequent executions of the encoding process.
