The 3GP file format is often used on mobile phones and other portable devices that have the function of recording and viewing audio and video in. The 3GP file contains multimedia data in an audio and video container format developed by the 3rd Generation Partnership Project (3GPP) consortium for mobile telephony. This extension significantly degrades the image quality but reduces the final file size. 3GP is a global standard and was originally conceived as a format that would allow audio and video to be transferred between mobile devices.
