4 To adjust the opacity of the entire clip, do one of the following:
 Drag the Opacity slider to the left until the value in the number field reads 50.
 Type 50 in the Opacity number field, then press Return.
 Move the pointer over the Opacity value graph line in the keyframe graph area;
when the pointer turns into the Adjust Line Segment pointer, drag down until the
value in the number field reads 50.
5 In the current timecode field of the Viewer, enter 01:00:02:00 to move the playhead.
6 Click the opacity keyframe button to create a keyframe at the new position of
the playhead.
Since it takes at least two keyframes to create a dynamic change to a parameter over
time, you’ll need to add another keyframe.
7 Move the playhead to 01:00:03;00 on the keyframe graph ruler, then create
another keyframe.
The image in
the Canvas now
shows both layers
blended together.
Entering the new
timecode moves the
playhead to this location.
A second keyframe is
added to the Opacity
value graph line.
