4-7-1 Sound Editing
Various operations, such as trimming, fade-in/fade-out settings, and volume level,
can be performed relative to both primary and superimposed soundtracks.
Primary soundtrack editing
Double-click the thumbnail of a movie file on the Storyboard to display the Movie
Editor. From there, click the [Sound Editor] button. Here operations can be
performed relative to trimming, fade-in/fade-out settings, and volume level.
Trimming superimposed sound
Upon placing your mouse pointer at either end of a superimposed sound clip, the
standard mouse pointer turns into a two-way arrow type pointer. Drag this pointer
to trim the play duration of the sound.
Editing superimposed sound
Double-click the sound icon on the Timeline that is associated with the sound you
want to edit. The Sound Editor will appear, allowing you to make changes relative
to trimming, volume level and fade-in/fade-out points.
