The Movie Fragment Random Access Box provides a table which may assist
readers in finding random access points in a file using movie fragments. It contains a track fragment random access box for each track for which information is provided (which may not be all tracks). It is usually placed at or near the end of the file; the last box within the Movie Fragment Random Access Box provides a copy of the length field from the Movie Fragment Random Access Box. Readers may attempt to find this box by examining the last 32 bits of the file, or scanning backwards from the end of the file for a Movie Fragment Random Access Offset Box and using the size information in it, to see if that locates the beginning of a Movie Fragment Random Access Box.
This box provides only a hint as to where random access points are; the movie fragments themselves are definitive. It is recommended that readers take care in both locating and using this box as modifications to the file after it was created may render either the pointers, or the declaration of random access points, incorrect.
