Speedy Video Converter Pro

Converting media files has become a frequent activity as new formats and devices appear. Speedy Video Converter Pro is aimed to convert between media formats.

Thus, it supports converting a wide range of video formats and extracting audio from video.
Its interface may seem unnecessarily complicated. In my opinion, too many elements are crowding the available space. However, I think you will not have much difficulty using this application. Even, if you are totally inexpert in these matters, you will soon learn how to use it with little effort.
As it supports batch conversion, you can create the list of files to convert and then choose an output profile. These have been separated into tabs according to the container type but there is also a tab labeled Audio and another named Device. When you choose one of the tabs, there are additional parameters to configure but you can simply choose one of the profiles and spare the rest. However, in case you desire to set specific parameters, you can customize them and even save the newly created profile for future use. In addition, if you want to make your video file compatible with a given device, you should just switch to the Device tab and find the name of your gadget there.
In general, Speedy Video Converter Pro is a fine application. When tested, it converted the selected files fast and accurately. However, I must tell you that there are myriads of converters out there, most of them allowing free trials, so perhaps you should try a few of them before you decide to buy this one.
