If an audio clip is not overlapped by another, you can select a fade-in or fade-out by right-clicking the clip and selecting Fade In or Fade Out from the menu.

Any audio effect you have applied to one clip will automatically be applied to both clips if you split the clip.

A cross-fade is automatically created if you drag one audio clip so it overlaps another.

COOL STUFF:

The so-called J-cut ....  This is when you're watching a scene and you hear the audio for the next scene before you see it.

The so-called L-cut ....  This is when the audio of the first scene continues into the following scene.

L-cut:  (audio continues into following scene)

  • Click-drag the desired video clip onto the Video track in the normal manner.  

  • Then, click-drag a second copy of that same clip onto the Audio/Music track below it.

  • Follow the same procedure with the second clip:  Drag the second clip into the Video track, then, drag a second copy of the second clip onto the Audio/Music track below it.

  • In the Video track, click and drag the right side of the first clip's trim handles to the left as desired.  (When you release the mouse, a gray overlap appears over the second clip in the timeline.)

  • Click on the second clip's Audio/Music track.

  • Click and drag the trim handles so the right side of the second clip in the Audio/Music track matches the end of its video clip in the Video track above.

  • Okay, now right-click the first video clip's Audio track, and click Mute.

  • Then, right-click the second video clip's Audio track, and click Mute.

  • So, both Audio track clips have been muted.  The viewer will hear the sound coming from the Audio/Music track, and the first clip's audio now extends into the second clip, which you should be able to see.

  • Of course, with the audio of the first clip extending into the second, you will want to be sure your second clip doesn't begin with someone speaking!

J-cut (audio precedes following scene)

  • Click-drag the desired video clip onto the Video track in the normal manner.  

  • Then, click-drag a second copy of that same clip onto the Audio/Music track below it.

  • Follow the same procedure with the second clip:  Drag the second clip into the Video track, then, drag a second copy of the second clip onto the Audio/Music track below it.

  • Click the Audio/Music track of the first clip.  Drag the trim handles on the right side of the clip to the left.  A space opens between the first and second clips in the Audio/Music track.

  • Click and drag the second clip's Audio/Music track to the left so that the two clips in the Audio/Music track are adjacent once again.

  • Click the second clip's Video track.  Click-drag the left side of the video clip to the right such that the clips all end at the same point in terms of their right ending points.  You may need to use the "nudge" feature to make this happen.  Select Clip from the menu and Nudge Left or Nudge Right as necessary.

  • As with the L-cut, right-click the Audio track of the first clip and select Mute.  

  • Right-click the Audio track of the second clip and select Mute.

  • So, both Audio track clips have been muted.  The viewer will hear the sound coming from the Audio/Music track, and the second clip's audio now will be heard before that clip's video is seen.

With both of the above procedures, one needs to carefully plan the ending of the first clip and the beginning of the second clip.
