AQ FLV Video Converter supports a large range of video formats, and will convert from FLV to any of them, so you don't have to worry about the technical side.
The interface of AQ FLV 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 in AQ FLV Video Converter is small, but comes with a snapshot button, so you can take screenshots 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, AQ FLV Video Converter lets you 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 from FLV, AQ FLV Video Converter does the job.
AQ FLV Video Converter is a passable video converter suitable for anyone who doesn't want to worry about technical details.
