10
Click on the black line and a point
will be added. This will be your
first keyframe.
■
11
Add another keyframe to the left.
By allowing your cursor to hover
over either keyframes you will see
it turns into a cross.
■
12
Drag the keyframe on the left to
the base of the clip.
■
13
Perform the same function to the
other clips, dragging keyframes to
the base of the clip. What you are
doing is plotting points so that the images will fade in and out at your
discretion.

Once you feel you have the points correctly plotted, render, if you need
to, and then play back the result. You may need to make further
adjustments if the result is not as you wish it to be.
If you follow points 1-7 you will achieve the result of a three-way superimposition.
This may be fine for your purposes. If, however, you want the images to fade in
and out at predefined points you need to use the Pen tool to plot keyframes. It
is possible to have a single image play, have another image dissolve over it to
be followed by a third image. I'm a big fan of three-way dissolves. They can
look great and produce subtle or high impact results depending on how they
are treated. The interface within Final Cut Pro is particularly suited to this type
of work. The hassles required in a tape suite to achieve these effects were
enough to persuade many editors never to try. As for the film world - now that
would have been really difficult.
Keyframing Filters
Just as Motion can be keyframed, Filters can also be keyframed. By definition
keyframing means to change over time. Therefore Filters can be animated over
time in a similar way to keyframing Motion Effects.
