462 17. Keyframing

3. Using the options in the Motion & Audio pane, create a very
simple zoom-in from Keyframe 1 (Starting Position) to
Keyframe 2 (Ending Position).

4. Preview the slide to see your simple motion in action.
You have some basic motion set up. Take note that the boxes which appear
next to the values in first and last keyframe are gray. We’ll go into that in a
moment.

5. Add a new keyframe to the timeline. Do not configure or adjust
the keyframe in any way.
6. Preview the slide again.

Notice that you added a new keyframe and previewed the slide, but the
effect is exactly the same. Take a look at the check box next to the Zoom
values for Keyframe 2. The boxes are empty. That means that the values at
this point in the effect are being automatically calculated by ProShow.

These values are automatically created because ProShow has not yet been
given any settings for Keyframe 2. All ProShow knows is what you want it
to do with the layer in Keyframe 1 and Keyframe 3, the first and last.
The values are gray for the first and last keyframes because those are always
manual. You must set those values for anything at all to happen on the
slide.

7. Change the Zoom value for Keyframe 2.

You'll notice that there is now a white check in the box.
This indicates that you have selected a specific value for
the keyframe that will override the automatic setting for
that point in time.
Disabling the checkbox will return the setting to the
automatic value.
