The Handbrake application, which is available for both the Mac and Windows operating systems, is primarily known as a DVD ripping tool. However, you can also use Handbrake to convert existing video files into different formats. For example, you can convert a file in the MOV format into the AVI or WMV format with Handbrake. Keep in mind that you may lose some degree of picture quality when converting to a different format.
Launch the Handbrake application on your PC or Mac computer.
Select the MOV file you want to convert in the "Source" pop-up window and then click "Open."
Open the "Format" drop-down menu and select the type of file you want to create from the list of available formats, which includes AVI and WMV.
Press the "Browse" button.
Navigate to the location where you want to save the converted version of the video file, enter a name for the converted file and hit "OK."
Press the "Start" button at the top of the window to convert the source video into the selected format.
