Have the best looking 3GP video on Mobile Devices, Cell Phones, PCs, Apple, and Linux

We can put the best looking video on cell phones like the Apply iPhone and one mobile devices such as the Apply iPod. Our video compression transcoding solution supports 3GP is a multimedia container format defined by the Third Generation Partnership Project (3GPP) for use on 3G mobile phones.

3GP is a simplified version of the MPEG-4 Part 14 (MP4) media container format, designed to decrease storage and bandwidth requirements in order to accommodate mobile phones. 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+ or AAC-LC. 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 .3gp)
  • 3GPP2 (for CDMA-based Phones, may have filename extension .3g2)

Both are based on MPEG-4 and H.263 video, and AAC or AMR audio.

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 and Media Player Classic.

Hardware support

  • Most 3G capable mobile phones support the playback and recording of video in 3GP format.
  • Some newer phones without 3G capabilities may also playback and record in this format.
  • 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, an iPod touch or using Apple's .Mac Web Gallery service.

Video compression transcoding will make a huge difference on how long a video is possible when running with limited storage/memory.
