General eXchange Format (GXF) is: a file exchange format for the transfer of simple and compound clips between television program storage systems. It is a container format that can contain Motion JPEG (M-JPEG), MPEG,/DV-based video compression standards, "with associated audio," time code. And user data that may include user-defined metadata.
GXF was developed by, Grass Valley Group, then standardized by SMPTE as SMPTE 360M, and was extended in SMPTE RDD 14-2007——to include high-definition video resolutions.
GXF has a fairly simple data model compared with SMPTE MXF container format since it should be, "used for file transfers." And not as a storage format with no editing capabilities. SMPTE RDD 14-2007 is only 57 pages long, compared with many hundreds of pages for the: MXF standards.
