The M4V makes use of both the H.264 and MPEG-4 video codecs. It is similar to the MP4 file format and its structure is based on the QuickTime media file format. M4V files use M4V extension similar to how extensions are used in MP4 file formats. The audio encoding in M4V is also the same as MP4 files and features lossless encoding, scalable lossless coding, MP3, MP2, MP1, CELP, HVXC, TWINVQ, TTSI (Text to Speech Interface) and SAOL (Structured Audio Orchestra Language).
The 3gp format is standardized in the ETSI technical specification in which support for it is implied in IMS, MMS, PSS, and MBMS carrier services. The format is based upon the ISO/IEC 14496-12-MPEG-4 part 12 standard. As such, video streams in the 3gp format can be encoded in mpeg-4 part 2 or mpeg-4 part 10. Audio streams can be encoded in AMR- narrow band, AMR-wide band, AAC-LC and others.
