A plurality of sub-picture bitstreams are obtained from memory, each sub-picture bitstream including a spatial portion of the video data and each sub-picture bitstream being independently coded. In at least one file, the plurality of sub-picture bitstreams are respectively stored as a plurality of sub-picture tracks. Metadata describing the plurality of sub-picture tracks is stored in a track box within a media file in accordance with a file format. A sub-picture base track is provided that includes the metadata describing the plurality of sub- picture tracks.
