MKV to 3GP: Convert Video from MKV(Matroska Video) to 3GP(3GP Mobile Video) with River Past Video Cleaner, MKV23GP converter, conversion

What is MKV?

Matroska aims to become THE standard of multimedia container formats. It was derived from a project called MCF, but differentiates from it significantly because it is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables the Matroska Development Team to gain significant advantages in terms of future format extensibility, without breaking file support in old parsers.

It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. Matroska is similar in conception to other containers like AVI, MP4 or ASF, but is completely open source. Matroska file types are .MKV for video (and audio) and .MKA for audio-only files.

To convert MKV files to other video formats, please have CCCP installed.

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.
