Video Edit Magic includes a very powerful method of varying volume over time. The volume of the audio tracks (Audio 1 and Audio 2) can be set and manipulated separately. Volume variations can be used to create audio effects such as Audio Cross Fades. To vary the volume of an audio track use the volume track of that audio track. A volume track is seen beneath each Audio Track. When the volume track is visible, a white minus sign is visible to its left. Clicking on it will hide the volume track, and turns the button into a plus sign. Clicking the plus sign restores the volume track.
