t It’s a curved path. Adobe Premiere Pro automatically uses Bezier curves
for motion.
t The little dots describe both the path and the velocity. Dots closer together
represent a lower speed; dots farther apart represent a higher speed.
t The little four-point stars are keyframes.

190 LESSON 10
Putting Clips in Motion
12 Drag the current time indicator to the position of the center keyframe. Drag the
center keyframe in the Program Monitor (the four-point star/square) down and
to the left.
Slower
Faster
Notice that the dots get closer together to the left of the keyframe and farther
apart to the right.
13 Play the clip. Note that it moves slowly until the first keyframe and then
speeds up.
14 Drag the center keyframe again, this time down and to the right (use the figure
shown here as a reference).
Now you’ve created a parabola with evenly spaced dots on both sides, meaning
the velocity will be the same on both arms of the parabola.
15 Drag the center keyframe in the Effect Controls panel first to the left and then
most of the way to the right.
16 Play this clip, and note how much slower it goes at the beginning and how much
faster it goes at the end.
It should behave the same way it did when you opened Lesson 10-1.prproj.
#
Note: By moving
the center keyframe,
you changed its
location and thereby
the distance the clip
traveled between it and
its adjacent keyframes.
But you didn’t change
the time between
keyframes. So, the clip
moves faster between
keyframes that are
farther apart and slower
for those closer to one
another.
#
Note: Now you
are changing the time
between keyframes
but not changing their
physical location in
the screen. The little
path/velocity dots in
the Program Monitor
spread out or slide
closer together, but
the keyframes do not
change locations.
