What is 3GP?

3GP and 3G2 are multimedia container formats used for the delivery and playback of audio/video files over high-speed wireless networks, especially mobile cell phones. Developed and defined by the 3rd Generation Partnership Project and 3rd Generation Partnership Project 2 respectively, they are built to contain various types of compressed data.

Both the 3GP and 3G2 file formats were especially designed so as to decrease the bandwidth and storage requirements in order to accommodate mobile cell phones. Structurally, they are based on the ISO file format defined in ISO/IEC 14496-12-MPEG-4 Part 12. The 3GP file can store video streams in MPEG-4 Part 2 (also called H.263) and MPEG-4 Part 10 (AVC/H264) formats, and audio streams in AAC-LC, HE-AAC v1, HE-AAC v2, AMR-NB, , and AMR-WB+. The 3G2 file, on the other hand, can store all the video streams as those of 3GP. As for the audio streams, it can store the same as those of 3GP, with the exception of HE-AAC v2 and AMR-WB, which it cannot store. Instead, it can store EVRC, EVRC-B, EVRC-WB, QCELP, SMV, and VMR-WB audio streams. The 3G2 Timed Text specifications are also more advanced than those of the 3GP.

3GP and 3G2 files can be opened on most 3G enabled mobile phones, and some 2G and 4G devices as well. File size, memory, and resolution limits may vary from phone to phone. When transferred on the computer, the files should be converted to more popular video formats. Total Movie Converter can convert MPEG, AVI, WMV to 3GP and vice versa without hassle.
