The AVI format was derived from the RIFF or resource interchange file format which is a generic container format. Digital video that is interleaved can be stored natively as a single stream conforming to the type-1 specification of the AVI file format. This has the disadvantage however of not being compatible with the video for windows framework. In general, the number of blocks in .avi files determine the amount of overhead. Overhead associated with the audio stream is determined by which codec is used to encode the stream for example AC3 or MP3-VBR.
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.
