iCoolsoft 3GP Converter for Mac provides us with several powerful editing functions. With them, you can customize out your own brand-new files if you like.
You can use the "Effect" function to adjust the Brightness, Contrast, and Saturation of the original AVI files.
The "Trim" function can help you to trim any time-length of clips. So you can convert only a part of the original file or you can delete some content you do not like of the original file.
The "Crop" function allows you to select the Aspect Ratio, including 16:9, 4:3, and Full Screen, for the target 3GP file. With that function, you can also crop the video image of the original file to zoom in some certain part or get rid of the black borders.
The "Watermark" function enables you to add text or picture watermark. You can set the transparency, location, font, size, color, etc. as you like.
