Even if several ringtones can be downloaded freely from the net, it is always better to create it yourself to get the best one. Here is a tool that can help you in this task.
A-one 3GP Video Converter allows you to convert videos into 3GP, a format that is compatible with all the existing portable phones. Since it is possible to convert only a selected part of the video ( by defining the start and the end point), it is then ideal for creating a ringtone for a portable phone. It can convert several files simultaneously and support most of the video formats including DivX, RMVB, Xvid, AVI, WMV, MPG, MPEG, VOB, MOV, QT, VCD, ASF and SVCD . In addition, it offers several options for customizing the output file.
