Nevo 3GP Suite is a very efficient package consisting of two video conversion applications, namely 3GP Video Converter and DVD to 3GP Converter.
In addition to converting the most popular video formats to 3GP, you can do the same with your DVDs so you can watch them on your mobile. You can convert the whole film for mobile ( a very long process) or just select a certain part which, bearing in mind the limited memory of most phones, is the most sensible option. In the case of DVDs, for example, you can select chapters that want to convert to 3GP whilst with other formats you have markers to delineate a scene from the video including audio, video and subtitle tracks. A bonus is the fact that you can normalize the sound levels which avoids the problem of "saturation" effects in the audio or when you capture frames from a DVD. However, why they've chosen to separate aspects of the program instead of combining it all in one application is a mystery. It would have looked and worked much better if they'd all been combined into one.
Nevertheless, a brilliant 3GP package that will surely handle any file or format you throw at it.
