Free 3GP Video Converter by Topviewsoft

Free 3GP Video Converter is a program with a self-explanatory title - it allows you to convert video files from various formats (including AVI, ASF, WMV, FLV and MOV) to the 3GPP or 3G2 extension, supported by mobile phones.
The interface of the application is clean and intuitive. Videos can be imported into the list via the file browser only, since the "drag and drop" method is not supported. Batch conversion is possible.
So, all you have to do is specify the output destination and extension, and proceed with the encoding process.
In addition, you can configure audio and video settings when it comes to the codec, resolution, bit rate, quality, frame rate, zoom mode, sample frequency rate and channels.
The video conversion tool runs on a very high amount of CPU and moderate system memory (other applications clearly run slower when Free 3GP Video Converter is open). But it manages to quickly finish an encoding job and to keep a pretty good image and sound quality.
All in all, Free 3GP Video Converter is a pretty good software for encoding clips. But it eats a lot of system resources. Nevertheless, we suggest you test it for yourself to see if it matches your preferences.
