Technical details

3GP is a simplified version of the MPEG-4 Part 14 (MP4) container format, designed to decrease storage and bandwidth requirements in order to accommodate mobile phones. It stores video streams as MPEG-4 Part 2 or H.263 or MPEG-4 Part 10 (AVC/H.264), and audio streams as AMR-NB, AMR-WB, AMR-WB+, AAC-LC or HE-AAC. A 3GP file is always big-endian, storing and transferring the most significant bytes first. It also contains descriptions of image sizes and bitrate. There are two different standards for this format: For other parts of the MPEG-4 standard, see MPEG-4. ... MPEG-4 Part 2 is a video compression technology developed by MPEG. It belongs to the MPEG-4 ISO/IEC standard (ISO/IEC 14496-2). ... H.263 is a video codec designed by the ITU-T as a low-bitrate encoding solution for videoconferencing. ... H.264 is a high compression digital video codec standard written by the ITU-T Video Coding Experts Group (VCEG) together with the ISO/IEC Moving Picture Experts Group (MPEG) as the product of a collective partnership effort known as the Joint Video Team (JVT). ... Adaptive Multi-Rate (AMR) is a Audio data compression scheme optimized for speech coding. ... Adaptive Multi Rate - WideBand or AMR-WB is a speech coding standard developed after the AMR using same technology like ACELP. The codec provides excellent speech quality due to wider speech bandwidth of 50 - 7000 Hz compared to narrowband speech codecs which in general are optimized for POTS wireline quality... AMR-WB+ is an audio codec that extends AMR-WB. It adds support for stereo signals and higher sampling rates. ... Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. ... High Efficiency AAC (HE-AAC) is a lossy data compression scheme for digital audio. ... In computing, endianness is the byte (and sometimes bit) ordering in memory used to represent some kind of data. ...

Hardware support

• Most 3G capable mobile phones support the playback and recording of video in 3GP format (memory, maximum filesize for playback and recording, and resolution limits exist and vary).
• Some newer/higher-end phones without 3G capabilities may also playback and record in this format (again, with said limitations).
• In iMovie '08, a movie exported using the "Tiny" setting is saved as a .3gp file and can be played on a Mac, an iPhone (as well as any other handset able to load and play the file), an iPod touch or using Apple's .Mac Web Gallery service.
• Audio imported from CD onto a PlayStation 3 will copy onto USB devices in the 3GP format.
