3GP to RM: Convert Video from 3GP(3GP Mobile Video) to RM(RealMedia) with River Past Video Cleaner, 3GP2RM converter, conversion

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 convert from 3GP video to other formats with River Past software, please have Apple QuickTime installed.

What is RM?

Select output format

Use the setting panel on the bottom of the window to control the output format. Click on the toggle to the left of the "Output Format" label to expand the panel. Select "RM - RealMedia" as the "File Type".

Change Audience

The audience specifies the target audience for your video streaming. It is normally bitrate based for streaming, or quality based if you just want to store the video for local playback. For example, to enable users of 512k DSL to play the video from internet, select "512k DSL or Cable" as the audience.

Change Video Settings

Click on the toggle to the left of the "RealVideo Settings" label to expand the panel.

Select "Specify" under "Size" and/or "Frame rate" to enter the video resolution and/or frame rate.

You can change the compressor, quality, size, and frame rate of the video.

RealVideo uses temporal compression. This means, only key frames contains complete information about the video frame. All other frames contains the difference from previous frame or frames. A "Key Frame" of 15 means there will be one key frame every 15 frames. Larger key frame setting will reduce the file size, but reduce the quality of all the none-key frames.

Change the "Mode" and "Complexity" settings according to your content so the RealVideo encoder can optimize its algorithm accordingly.

Change Audio Settings

Click on the toggle to the left of the "RealAudio Settings" label to expand the panel.

Select the audio compressor for the conversion. You may also change the sample rate, channel (stereo or mono), and bits/sample. You can also leave the setting to "Automatic" so the software choose the best settings depending on the original material.
