Free 3GP / MP4 Converter (formerly Green Video Converter)

As the name of this software implies, Free 3GP / MP4 Converter allows you to encode media files to the 3GP and MP4 format. It can be easily used by all user levels.

This is a portable software, so installing Free 3GP / MP4 Converter is not necessary. It means that you can place the tool on a removable device (like a USB flash drive), plug it into any computer and directly run its executable file. What's more important is that your Windows registry keys will not be changed.

The interface of the program is plain and pretty intuitive. Video clips can be imported into the list by using the file browser only, because the "drag and drop" method is not supported. Batch processing is allowed.

In the list you can check out the source path, start and end time, along with output profile and status of each file. After you set the destination folder and output file type, you can start conversion.

But you can also modify audio and video settings when it comes to the quality, size, frame rate, sample frequency rate and channel mode. Plus, you can trim clips by marking their start and end time, as well as remove an item from the list.

The video encoding software runs on a moderate amount of system resources, can take a while to complete a task but manages to keep a good image and sound quality. Unfortunately, there is no help file available, the interface is outdated and its response time is not very good. We recommend Free 3GP / MP4 Converter with reservations.
