480 17. Keyframing

You can adjust the soundtrack volume using any keyframe that exists in a
slide. This means on any slide, you can go to any or all of the tabs listed
above and apply a volume adjustment to a keyframe.

Tip #1: When you have a slide with multiple objects using keyframes, the
Keyframe Editor will help you see how all of those keyframe times line up,
making it easier to coordinate volume changes.

Tip #2: If you're goal is to make volume changes that do not go hand in
hand with something happening on a slide, it's always a good idea to stick
to using only one of the tabs listed earlier and entering all of your volume
changes there.

Tip #3: When you have a slide with multiple objects, sometimes you may
find yourself applying different volume levels to the same point in time
within a slide.

For example: For Layer 1, you add a keyframe at the 4 second mark. Under
the Motion & Audio pane, you set the volume level to 25% for that
keyframe.

Then with a caption selected, you add a keyframe at the 4 second mark.
Under the Caption Motion & Adjustment pane, you set the volume to 85%.

When this happens, ProShow will always use the lowest volume setting.

To Control the Soundtrack Using Keyframes
1. Add 5 images to a show, then drag and drop an audio file onto the
Soundtrack bar.
2. Double-click on slide 3. (For best results with this example, we
need to make sure there are slides before and after the slide we'll
be editing).

3. With the layer selected in the Layers List, click the Effects tab
above the preview.
