Movie Maker allows you to change the volume of your video clips, but the method
involved is not obvious ... you can actually expand the video track and change the volume clip-by-clip.
This is useful when you have background music that is drowning out portions of your video.
The following film is from the
video training series "Introduction to Movie Maker 2" and is a screen captured video that
walks you through volume changing process.
The movie is in QuickTime format. If you can't see the movie, you may need to install the
latest (free) QuickTime
