Anti-flicker Filter
: This feature is useful for images that contain high-frequency
detail, such as fine lines, hard edges, parallel lines (moiré problems), or rotation.
Those characteristics can cause flickering during motion. The default setting
(0.00) adds no blurring and has no effect on flicker. To add some blurring and
eliminate flicker, use 1.00.
1
Open Lesson 10-2.prproj, and open the Finished sequence.
2
Play the clip to see the animation.
This is how the Motion effect will look by the end of this exercise.
3
Open the Practice sequence to start with the same clip but with no effects.
4
Place the current-time indicator at the beginning of the clip, expand the Motion
effect, click Position’s “Toggle animation” button to activate keyframing, and
move the center of the clip to the upper-left corner (position 0, 0).

Note:
The percent
refers to the clip border
perimeter, not the clip
area. So, 50 percent
is equal to 25 percent
in terms of area, and
25 percent is equal to
6.25 percent in area.

LESSON 10
Putting Clips in Motion
5
Expand the Scale parameter, click Scale’s “Toggle animation” button to activate
keyframing, and drag the slider to 0.
That sets the size to 0 for the beginning of the clip.
6
Drag the current-time indicator about a third of the way into the clip, and click
the Reset button. That creates two keyframes that use Motion’s default settings:
the clip at full size and centered in the screen.
7
Drag the current-time indicator about two-thirds of the way into the clip, and
click the Add/Remove Keyframe button for Position and for Scale.
The clip will remain centered and at full-screen for the time between the
two keyframes. You could also have clicked Reset again to use those default
parameters and achieve the same effect.
8
Press Page Down and the left arrow key with the Timeline active to move
the current-time indicator to the end of the clip, and change the Position
parameters to 1280, 720 (lower-right corner).
9
In the Program Monitor, drag a bounding box corner handle to shrink the clip
all the way down to the center crosshairs. That sets Scale back to 0.
