An exemplary recording apparatus records video data and audio data in a recording medium in an MPEG4 file format. A first MPEG4 file format generating circuit generates MPEG4 data including multiplexing information on a multiplexing of the video data and the audio data stored in a MOOV BOX of the MPEG4 file format. A second MPEG4 file format generating circuit configured to: generate MPEG4 data including the multiplexing information stored in a MOOF BOX of the MPEG4 file format; store reproduction information required for reproducing the MPEG4 data generated by the first MPEG4 file format generating circuit from the generated MPEG4 data in a BOX of the MPEG4 file format for storing types of data that are ignored at a time of playing MPEG4 data; and to output the MPEG4 data to an external apparatus via the transmitting unit. A controller records the MPEG4 data in a recording medium.
