MP4/M4V to 3GP: Convert Video from MP4/M4V(MPEG-4 Video) to 3GP(3GP Mobile Video) with River Past Video Cleaner, MP4/M4V23GP converter, conversion


What is MP4/M4V?

A video compression standard planned for late 1998. MPEG-4 extends the earlier MPEG-1 and MPEG-2 algorithms with synthesis of speech and video, fractal compression, computer visualisation and artificial intelligence-based image processing techniques.

MPEG.ORG is an excellent source for additional information on MPEG format and usage.

There are several ways to decode MP4 video. Most of the time, having Apple QuickTime installed is sufficient. Occasionally, a file is not compatible with QuickTime. You will need to install CCCP when that happens.


What is 3GP?

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 Player.

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 encode 3GP video in River Past software, you will need River Past 3GP Booster Pack, and need to have Apple QuickTime installed.
