What is RM?

A streaming technology developed by RealNetworks for transmitting live video over the Internet. RealVideo uses a variety of data compression techniques and works with both normal IP connections as well as IP Multicast connections.

More information is available on RealNetwork web site.

To convert RealMedia to other formats with River Past software, please have Real Alternative installed. If the RM file was encoded with AC-3 audio, you may also need to install AC-3 Decoder Filter.

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.
