Click the keyframe button for the Opacity parameter to create a keyframe at the new
position of the playhead.
Because it takes at least two keyframes to create a dynamic change to a parameter over
time, you’ll need to add another keyframe.

Move the playhead to 01:00:03:00 on the keyframe graph ruler, then create
another keyframe.

In the keyframe graph area, move the pointer to the left of the two keyframes on the
Opacity keyframe graph line. When the pointer turns into the Adjust Line Segment
pointer, drag down until the number field reads “0.”
The shape you’ve given to the Opacity parameter’s keyframe graph line makes the top layer
completely invisible for the first 2 seconds of playback. Over the next second it fades up
until it reaches a total opacity of 50 percent, which looks like an even mix of both layers.
A second keyframe is
added to the Opacity
keyframe graph line.
A segment at 50 percent
opacity results in an even
mix of both layers.
The increase from
0 percent to 50 percent
causes the clip on track
V2 in the Timeline to fade
up over the clip on
track V1.
A segment at 0 percent makes
the top layer invisible for the
duration of the segment.
