This article teaches you how to convert a WMV (Windows Media Video) file into an MP4 video file. MP4 files are more universally playable than WMVs, so converting WMVs into MP4s is a logical choice if you want to be able to play your video on virtually any platform. You can use a free program called HandBrake to convert your video; if the video isn’t sensitive or private, you can also use an online service to convert it.
