MPEG-1 to 3G2: Convert Video from MPEG-1(MPEG-1 Video) to 3G2(3GPP2 Mobile Video) with River Past Video Cleaner, MPEG-123G2 converter, conversion

What is MPEG-1?

The first MPEG format for compressed video, optimised for CD-ROM. MPEG-1 was designed for the transmission rates of about 1.5 Mbps achievable with Video-CD and CD-i. Its compression algorithms allow better than VHS quality video and almost CD quality audio to be compressed onto and streamed off a single speed (1x) CD-ROM drive. MPEG encoding can introduce blockiness, colour bleed and shimmering effects on video and lack of detail and quantisation effects on audio. The official name of MPEG-1 is International Standard IS-11172.

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

What is 3G2?

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 3G2 video in River Past software, you will need River Past 3GP Booster Pack, and need to have Apple QuickTime installed.

Additional Requirements

To convert from MPEG-1(MPEG-1 Video) to 3G2(3GPP2 Mobile Video) video with River Past Video Cleaner, you must have River Past 3GP Booster Pack installed.

Launch River Past Video Cleaner

Troubleshoot

If you have the 3GP Booster Pack installed, and don't see the 3GPP2 output option, you have a problem with your QuickTime installation.

You need to have the latest QuickTime installed. Occasionally, QuickTime may be corrupted. In any case, reinstall QuickTime should fix this problem.

Note: To convert to 3GP/3GPP video files, you must have Apple QuickTime installed.

Note: The 3GP Booster Pack must be installed for the "3GP2" output option to show.

Change Video Settings

Click on the toggle to the left of the "Video 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.

The bitrate is in the unit of kbit/second. Use this formula to calculate the video size per minute:

Video size/minute (KByte/second) = bitrate / 8 * 60.

Change Audio Settings

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

Select the audio compressor for the conversion. Depending on the compressor, you may also change the sample rate, channel (stereo or mono), bits/sample, and bitrate.
