When most people want to convert a video, they don't really care whether it's AVI or MPEG, just that they want it to work on their device. AQ iPhone Video Converter supports a large range of video formats, and will convert for any type of iPhone, so you don't have to worry about the technical side.
The interface of AQ iPhone Video Converter will be familiar to anyone who's tried a video converter before - you have a button for adding your video files, drop down menus for choosing the conversion profile, a window to preview the video, and a big Start button to do your conversions.
The video preview window is small, but comes with a snapshot button, so you can take screen shots of your videos too (in the original format size). Conversion speed is fine, and in the registered version you can perform batch conversions. The demo only does one, and also sticks a big opaque watermark in the center of the converted video, so it's really only useful as an evaluation of the converter.
For the more advanced users you can create your own conversion settings too, as well as editing the video length, and adding your own watermark. If you only want to convert video for your iPhone, AQ iPhone Video Converter does the job.
AQ iPhone Video Converter is a passable video converter suitable for anyone who doesn't want to worry about technical details.
