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, or 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,[1] and was extended in SMPTE RDD 14-2007[2] 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.[3] SMPTE RDD 14-2007 is only 57 pages long, compared with many hundreds of pages for the MXF standards.
