I just bought FRAPS. How do I add music to the video file?

Probably the easiest way would be to import your FRAPs footage into Windows Movie Maker, since that is included in Windows and you will definitely have it, so you won't need any other dubbing or editing software. WMM is usually to be found in the Windows accessories from the Start menu, they shifted its location in Vista, but look on the Start menu and you'll find it.Create a new Windows Movie Maker project, then import your music file into your project (MP3s will work, as will WAV files). When you've imported your footage and your sound file into WMM, drag the footage and the sound file onto the timeline and snyc them up by sliding them around on the timeline. Export the file as a movie when you are done, and you will have a file with the music on it.From that description, it sounds complicated, but is not at all and very intuitive once you have WMM open, should only take you a couple of minutes. WMM is more capable than most people give it credit for, I edited this movie in it:http://www.youtube.com/watch?v=X9QjxvrhkrQAl
