As suggested by its name, ImTOO FLV to 3GP Converter can help you convert video from FLV to 3GP. The first is widely used to stream video contents from the Internet while the second is used by many phones and portable devices. Thus, converting FLV to 3GP allows you to view downloaded video on 3GP phones.
The program has a nice interface, suited for batch conversion. In addition, it is designed in a tutorial-fashion, with explicit instructions on how to use it. The tool supports adding not only individual files but also complete folders. You can preview the imported items to check their contents or take snapshots of your favorite frames. However, the software does not allow any type of authoring actions, not even those available in similar software, such as trimming, cutting and merging. Only splitting is available.
Unluckily, this converter is too specific as it only supports converting between the two file types mentioned above and it includes only two output profiles. However, these presets can be customized and new ones can be created from them. The program has a built-in bitrate calculator to help you get the maximum quality for the desired file size.
In general, ImTOO FLV to 3GP Converter can do its job well. Since it supports modern hardware, it can convert quite rapidly and accurately. However, it is too restricted in terms of available formats; therefore, you might well consider spending your money on a more comprehensive converter.
