With the expansion in capacity and range of mobile devices, users are increasingly demanding to be able to watch their favourite visual content on the move.

Acala 3GP Movies Free is a professional program for converting Avi, DivX, Xvid, Mpeg, Vob and several other formats to work on mobile devices. The interface is very professional yet easy to use and conversions are usually excellent quality and lightning fast.

The developer claims times of just 10 minutes to convert a two hour movie to 3GP and while this may be a little overstretching it, it certainly works quicker than any other 3GP converter I can remember. The good thing is that the program works in a similar way to a video editor - you can mark the in and out points of your film so you can cut out annoying titles at the beginning and end if you don't want them.

If you've got a lot of files to convert, it also supports batch conversions. You can easily split and preview films as they are converting to see whether the quality is to your liking.

All-in-all, this is an excellent 3GP conversion tool, especially if you need to cut and splice files and are in a hurry.
