3GP is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for use on 3G mobile phones. Multimedia is media and content that utilizes a combination of different content forms. A container format is a computer file format that can contain various types of data compressed by means of standardized audio/video codecs. The 3rd Generation Partnership Project ( 3GPP) is a collaboration between groups of telecommunications associations to make a globally applicable third generation ( 3G 3G is the third generation of mobile phone standards and Technology, superseding 2

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. An Internet media type, originally called a MIME type after MIME and sometimes a Content-type after the name of a header in several protocols whose value A container format is a computer file format that can contain various types of data compressed by means of standardized audio/video codecs. MPEG-4 Part 14, formally ISO / IEC 14496-142003, is a Multimedia Container format standard specified as a part of MPEG-4 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. MPEG-4 Part 2 is a Video compression technology developed by MPEG. H263 is a Video codec standard originally designed as a low-bitrate compressed format for Videoconferencing. H264 is a standard for Video compression. It is also known as MPEG-4 Part 10, or MPEG-4 AVC (for Advanced Video Coding) Adaptive Multi-Rate (AMR is an Audio data compression scheme optimized for Speech coding. Adaptive Multi Rate – WideBand ( AMR-WB) is a Speech coding standard developed after the AMR using same technology like ACELP. Adaptive Multi Rate – WideBand plus ( AMR-WB+) is an audio Codec that extends AMR-WB. 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. 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:
- 3GPP (for GSM-based Phones, may have filename extension . The 3rd Generation Partnership Project ( 3GPP) is a collaboration between groups of telecommunications associations to make a globally applicable third generation ( 3G GSM ( Global System for Mobile communications: originally from Groupe Spécial Mobile) is the most popular standard for Mobile phones in the 3gp)
- 3GPP2 (for CDMA-based Phones, may have filename extension . The 3rd Generation Partnership Project 2 ( 3GPP2) is a collaboration between telecommunications associations to make a globally applicable third generation ( 3G) Code division multiple access ( CDMA) is a Channel access method utilized by various radio communication technologies 3g2)
Both are based on MPEG-4 and H.263 video, and AAC or AMR audio. H263 is a Video codec standard originally designed as a low-bitrate compressed format for Videoconferencing.
When transferred to a computer, 3GP movies can be viewed on Linux, Mac, and Windows platforms with programs such as VLC media player, RealPlayer, QuickTime, GOM Player and Media Player Classic. Linux (commonly pronounced ˈlɪnəks Macintosh, commonly nicknamed Mac is a Brand name which covers several lines of Personal computers designed developed and marketed by Apple Inc Microsoft Windows is a series of Software Operating systems and Graphical user interfaces produced by Microsoft. RealPlayer (briefly known also as RealOne Player) is a proprietary Cross-platform media player by RealNetworks that plays a number QuickTime is a Multimedia framework developed by Apple Inc, capable of handling various formats of Digital video, Media clips sound text GOM Player ( G retech O nline M ovie Player) is a freeware media player for Microsoft Windows. Media Player Classic ( MPC) is a compact media player for Microsoft Windows.
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). 3G is the third generation of mobile phone standards and Technology, superseding 2
- 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. Ripping is the process of copying audio or video content to a Hard disk, typically from Removable media or media streams.
