The 3rd Generation Partnership Project
(3G/3GPP) is a collaboration agreement that was established in December 1998.
The 3GPP and 3GPP2 specifications call out specific types of media that can
exist in .3gp and .3g2 files.
Once you move a video from cell phone to your PC, the easiest way to play
it is to use Apple's QuickTime
In general, if a cell phone record a 3g2 video, it should conform to the
3G2 standard. However, a cell phone may not has the ability to play all variety
of 3G2 videos due to limited codec support on the cell. Thus, it is easy to
convert a cell phone 3G2 to a video format playable on a computer, but it is
not so easy to convert a PC video to a 3G2 which is compatible with your particular
brand of cell phone.
To convert from 3G2 video to other formats with River Past software, please
have Apple QuickTime
Defined by Microsoft, AVI stands for Audio
Video Interleave. It is a special case of the RIFF
(Resource Interchange File Format). AVI is the most common format for audio/video
data on the PC.
AVI is Microsoft's response to Apple's QuickTime
technology. Early AVI files were limited on choice of video and audio codecs,
quality, and resolution. However, with the introduction of DirectShow, AVI became
a very flexible and powerful architecture. Some newer codecs including DivX
and XviD enable AVI files to have similar
or even better quality than DVD.
