iStonsoft Video Converter turns video clips of various formats into ASF, MOV, WMV, HD video and other file types. It can also extract audio streams and save them to MP3, M4A, OGG, WAV and WMA (among other popular audio formats), as well as prepare clips for playback on iPod, iPad, iPhone, Android, BlackBerry and other devices. It may sound like a complex video conversion tool, but it's actually quite simple to work with.

The setup procedure is quick and uneventful. In the interface department, iStonsoft Video Converter opts for a clean look and intuitive options, enabling users to import clips using the file browser, tree view or drag-and-drop support.

As you may have probably figured out, batch conversions are possible, meaning that you can process multiple clips at a time to reduce overall task duration. Apart from indicating the output profile and saving directory, it is possible to preview clips in a built-in player and capture frames.

Advanced users may modify audio and video parameters for the resulted file when it comes to the resolution, encoder, frame rate, sample rate, and channel mode. Settings can be restored to default, as well as saved to a new profile or overwritten to an existing one. Additionally, it is possible to customize the display of profiles.

iStonsoft Video Converter does not take a long time to finish conversion jobs, during which it remains fairly light on CPU and RAM. It delivered some quality clips during our evaluation, and we haven't come across any stability issues. Although other video conversion tools have a richer skill set, iStonsoft Video Converter offers support for an extensive list of file types, customizable audio and video settings, as well as speedy tasks.
