Video Converter Factory Pro is a simple-to-use yet powerful application that allows you to convert among a large variety of video and audio file formats. It supports a large variety of formats, neatly organized into various categories by its interface. Its interface is actually not only easy-to-use and effective, but also original-looking and elegant. Besides the large number of supported formats and the cool interface, Video Converter Factory Pro also offers many other advantages, including support for batch converting multiple files at the same time.
Furthermore, every output format can have its details configured to your liking. You can set the bit rate, frame rate, and other aspects as you prefer. Experienced users will surely enjoy the additional video editing functions provided by Video Converter Factory Pro. This tool can also crop, cut, and apply color effects to the loaded videos.
Anyway, there's also a downside regarding this tool. Converting a 5 MB 45-seconds MP4 video to an MKV file took around 15 minutes, so I guess the conversion speed is not the strong point of this tool. 15 minutes are a lot for converting a simple little video of less than one minute in length.
To cut a long story short, Video Converter Factory Pro has plenty of good parts, so it gets my recommendation despite the fact that it also comes with abysmally low conversion speed.
