ISO Base Media File Format
From Just Solve the File Format Problem
ISO Base Media File Format (occasionally abbreviated BMFF) is a metaformat for "time-based" media formats (mainly audio and video). It is based on the more-general metaformat we're calling boxes/atoms format.
It is defined by Part 12 of the MPEG-4 standard, and also by Part 12 of the JPEG 2000 standard.
Much of the format was copied from QuickTime format, though not all QuickTime files use ISO Base Media File Format.
Among the formats based on it are MJ2 and MP4.
Identification
Files use boxes/atoms format, and have both an "ftyp" box and an "moov" box. (We're not aware of any other standard formats that meet these conditions.)
