BIFS Text (.bt) is a authoring format(textual format) used by GPAC, which have its roots in the mp4tool from Jean-Claude Dufourd.

You can create an .bt file from a existing MP4 file with:
MP4Box -bt file.mp4

Beside BIFS Text, GPAC supports XMT-A which is defined in MPEG-4 part 11 (MP4Box -xmt file.mp4).
