WinX Free WMV to MP4 Converter is a free video converter. It can be used to convert Windows Media Video files into MP4 files. There aren't any limitations and the converter is fully functional. The only accepted input file is WMV and the application can convert those files into MPEG-4 or H.264 files within an .MP4 container.
This application is one of the many new, free converters that WinX has released recently. I think it is part of a great marketing campaign. After using some of them, I really feel like buying one of the paid apps. Because I know that they all work well.
These free converters share the same user interface. Although it is basic and simple, it manages to keep the process easy and intuitive. There is a "getting started" guide on the main window that helps you through the process. The conversion settings are at the bottom of the window. And, although there isn't much you can change here, the basic settings are all there. You can tweak the video bitrate and resolution and choose one of the available audio and video formats.
In my testing, the application performed quite well. I had no problems converting a few WMV files into both H.264 and MPEG-4 files. These are very similar, and you can't go wrong with either of them.
