What is 3GP ?

Stands for Third Generation Partnership Project sometimes called 3GPP it is a multimedia container format defined by 3GPP for use on 3G mobile phones. It is a simplified version of MPEG-4 Part 14 (MP4). 3GP files have the filename extension .3gp or .3g2.

3GP stores video streams as MPEG-4 or H.263, and audio streams as AMR-NB or AAC-LC formats. 3GP files are always big-endian, storing and transferring the most significant bytes first. 3GP also describes image sizes and bandwidth, so content is correctly sized for mobile display screens.

3GP files are viewable on a PC using Media Player Classic, MPlayer, QuickTime, VLC Player, Xine or Zoom Player.

3GP video files can be converted to many other video formats using either 3GP Video Converter or a combination of MPEG Streamclip and QuickTime Alternative. MPlayer’s MEncoder also can convert 3GP video files (If MPlayer can read it, MEncoder can convert it). SUPER(C), by eRightSoft, is a freeware converter which can convert 3GP to many other formats. It supports every major video format and most audio formats. It also has the ability to encode to a different screen resolution or a bitrate.

Most 3G enabled phones have support for this format and most even capture videos in this format. When viewed on a PC screen the video quality is similar to that seen on the mobile screen.

Often security cameras use this format, as you can fit hours of footage in a small amount of space. This is also why mobiles use the 3GP format.

In practical implementations for Videos, 3GP is used in 2 flavors:

* 3GPP (for GSM Based Phones)
* 3GPP2 (for CDMA Based Phones) Related Posts Plugin for WordPress, Blogger...
