An information processing apparatus includes an encoding and decoding unit for performing a data conversion process by decoding encoded still image data acquired from an information recording medium and generating moving image encoded data based on the decoded still image data, a medium control unit for performing a data re-recording process by recording the moving image encoded data, generated by the encoding and decoding unit, on the information recording medium in a predetermined data recording format, and a controller for controlling the data conversion process of the encoding and decoding unit and the data re-recording process of the medium control unit. The controller controls the data conversion process and the data re-recording process in response to user input information as to whether to execute the data conversion process.
