difference! That brings me to my next
point.
In animation, just as in film and video edit-
ing, timing is crucial. The difference of a
few frames can literally make or break a
scene. That's why features like the Dope
Track are so vitally important. They make it
easy for us to fine-tune the timing of indi-
vidual elements in our scene. Let's take a
look at some of the other features available
in the Dope Track.
Keyframes can be added to the timeline
simply by double-clicking. The values for
the new key will be taken from those found
at the location of the Frame Slider.
1.
where we just created the new key. A
marker will be created.
2. Drag your Frame Slider over to frame
20. You'll notice that the marker turns
yellow.
3. Right-click on the Dope Track and
select Set Marker Text from the
pop-up menu. In the requester that
appears, type the name ZoomZoom .
This will remind us that on this
keyframe, the logo is zooming to the
back. Press OK in the requester.
4. A marker label now appears in the info
field to the bottom left of the timeline
(see Figure 15-11).
At this point we can move our key away
from frame 20 and still have a visual
reminder of its original location. I don't
really want the ZoomZoom keyframe, how-
ever, so let's delete it.
1.
Move the Frame Slider to frame 42.
2.
Now move your mouse over frame 20
in the Dope Track and double-click. A
new keyframe will be created.
3.
Play the scene using the playback con-
trols. You'll notice that the logo now
jumps back on the Z axis at frame 20.
Click the key we created at frame 20 to
select it. Now right-click. This brings
up a context-sensitive pop-up menu.
Markers can be placed on the Dope Track
to identify specific locations. They can even
be labeled to provide greater clarity as to
the purpose of each marker.
1.
2.
Scroll down and select the Delete
Keys option.
3.
The logo will immediately jump for-
ward again, as the key that pushed it
back has been removed.
Holding the < Shift > key down,
double-click the timeline at frame 20
