Basic Audio Editing
3. Adjust the pan or level for each new segment in the Audio Mixer tool.
Almost always, you will then add a dissolve to smooth the change (as
you’ll learn in the next section).
Adding Audio Crossfades
An audio crossfade is a dissolve applied to an audio transition. That is,
as the audio level on one side of an edit fades out, the audio level on the
other side of the edit fades in. Audio crossfades can often eliminate pops
in transitions and will also smooth changes in level or pan across the edit.
To create an audio crossfade with a dissolve:
1. Place the position indicator on or near a transition in the Timeline.
2. Select the tracks on which you want to add the dissolve.
3. In the Tool palette, click the Quick Transition button
or press the
backslash (\) key on the keyboard.
The Quick Transition dialog box appears.
4. In the Quick Transition dialog box, specify the following fields:
Duration: The dissolve’s duration expressed as a number of frames.
The default length (one second) is 30 frames or 24 frames for NTSC
projects and 25 frames for PAL. You can also adjust the duration by
dragging the left or right edge of the outer purple box (the cursor
becomes a double-sided arrow).
Depending on the situation, a very short (8 frame) or very long (90 frame)
dissolve may best serve your purpose. Usually, if the audio is dialogue, a
short transition is better, and if the audio is ambience, a longer transition is
better. It’s best practice to test a value and then adjust accordingly.
TI P If the crossfades
add undesired audio or
cut off desired audio,
you can tweak them
individually.
