554 17. Keyframing

Controlling Sound as Part of Your Effects
One of the creative advantages to controlling the Soundtrack with
keyframes is that it gives you the ability to coordinate volume changes
along with your effects.

For example, if you have an image fly onto the screen and hold still for a few
seconds, you can also lower the soundtrack volume at the same time,
allowing your audience to focus more on the image and less on the music.

The reverse is also true. If you have an image that really connects with
certain words or a melody, try increasing the volume as that image appears
on screen.

Video Layers and Soundtrack Keyframes
Keyframing your soundtrack is especially helpful when using video layers
that contain audio.

As video layers begin to play, you can customize the Soundtrack volume
using keyframes to make sure the audio within the video clip isn't over-
powered by your Soundtrack.
This also gives you the ability to have multiple video layers on the same
slide with completely different Soundtrack volume levels as each video
layer is played.
For more information about using video layers with audio, see Chapters 9
and 12.
