These day I spent some days in searching a method to simplyy convert my video files into 3GPP (see at the end of the post for info about 3GP format) video format for viewing them through mobile devices.
I start my searching on Nokia Forum site and I found the Nokia Multimedia Converter 2. It's a freeware tool for converting common multimedia files (such as AVI, WAV, MPEG, and MP3) into 3GPP. But in order to install the software you need a serial number you can ask for free to Nokia Forum (download section).

Very simple to install and to use the software makes possible with a few clicks to convert your video into 3gp. You can find a precise tutorial on MobyMemory site.
Another interesting software is ImTOO 3GP Video Converter v2.1, a powerful 3GP converter which can convert AVI to 3GP, MPEG to 3GP. ImTOO 3GP Converter can also convert RM, MP4, MOV, WMV, MPEG, AVI to 3GP file or convert 3GP video clip to AVI and MPEG. You can use it to convert MPEG or AVI to 3GP video clip and play them in Motorola, Nokia mobile phone or other software 3GP player. Pay attention it's not a free tool :)
The Mobile 3GP converter uses "3GPtoRawAVI" converter to convert 3GP files to uncompressed AVI files (*.avi) in a user-friendly way. The 3GP video files must have audio in order to be converted. It's a simple but easy to use and free tool !
See also another non-free software tool, Xilisoft 3GP Converter. On this site you'll find a guide and other 3gp converte tool.
Via Wikipedia : 3gp is a file format which is used in mobile phones to store media (audio and video). This file format is a simpler version of "ISO 14496-1 (MPEG-4) Media Format", which is similar to MOV (used by QuickTime). 3gp stores video as MPEG-4 or H.263. Audio is stored in AMR-NB or AAC-LC formats.In this format, values are stored as big-endian.
3GPP also describes image sizes and bandwidth, so content is correctly sized for mobile display screens.
The current 3GPP version is release 5, offering the most standardized feature set for encoding, distribution and playback.






















good info! I had tried http://www.thugsatbay.com/zweistein/ Zwei-Stein a few days ago to go from 3gp to AVI, and it looked great but I couldn't get the audio to sound right.
