3GP Video Format and Smartphone Information
3GP is a modified version of the MPEG-4 or the H263 video format that has been adapted to fit the needs of mobile phones. The video used by M2Convert for Smartphones is based on the h263 video codec and the AMR audio codec. 3GP files are typically viewable on a PC using QuickTime or RealPlayer, otherwise they require a 3GP directShow filter to play in Windows Media Player.
If you are not able to view 3GP files on your PC, this is because you are missing a 3GP codec on your computer. Installing the puchased copy of M2Convert for Smartphones will allow your computer to view 3GP movies without the need to find and download an additional codec. Once M²Convert for Smartphones has been installed and purchased, you should be able to view the converted 3GP videos in Windows Media Player for as long as M²Convert for Smartphones remains installed.
Video Size and Storage on Smartphones
Smartphones are typically not designed to hold large amounts of video because they lack the memory resources and have smaller screen sizes of other devices such as the iPod, Zen or Zune. As a result, there are some options to consider when creating and storing videos on your phone. You can select different codecs, video sizes and quality levels for the particular phone you are using. Because all videos are different, it is impossible to correlate file size to video time, however, the charts below should provide a rough estimate of resultant file size when converting a 10 minute video to AGP using the available quality levels and video resolutions.
