.trif is a file format that was developped by MPEG Systems for internal
purposes before MP4 was standardized. It is still supported in some MPEG
Systems tools but has now been replaced by MP4, which is the ISO official
multimedia file format. There is no ISO official specification of it.
Kind regards,
Olivier
