What is 3GP video format? 3GP video format is a multimedia container format defined by the Third Generation Partnership Project(3GPP) and used on mobile phones to store media including audio and video, usually with a .3gp extension. 3GP video format is a simplified version of the MP4 container format, designed to decrease storage and bandwidth for better streaming on mobile phones. There are two different standards for 3GP video file formats: 3GPP for GSM-based phones (.3GP) and 3GPP2 for CDMA-based phones (.3G2).
As for the actual video inside, it is generally MPEG-4 Part 2, H.263 or H.264. AMR or AAC audio used with 3GP video format. Designed for efficiency to make it suitable for streaming across mobile phone networks and storing on mobile devices with very little storage capacity, the video usually has a resolution of 176 x 144 or 176 x 120, and rarely exceeds 320 x 240 (or 368 x 208 for widescreen) while audio will usually be encoded as either MP3 or AAC-LC . Frame rates for most mobile devices are Limited to 15fps.
Nowadays 3GP video format has become the new worldwide standard for the creation, delivery and playback of multimedia over 3rd generation, high-speed wireless networks. 3GP video file formats are used by quite a number of mobile phones as the standard format for recording video clips.
