Step 5: Position and keyframe the image at the pan start and end points
The Center parameter determines where the image appears (or doesn’t appear)
onscreen. You’ll create the image movement by setting a starting and ending Center
location with keyframes. To generate the movement path for you, Final Cut Express HD
interpolates the position of the image between these two points
1 Move the playhead to the time when you want the image pan to start.
2 Move the position of the image in the Canvas to the starting position of the pan.
3 Control-click the Keyframe button in the Canvas, then choose Center from the
shortcut menu.
A keyframe is created.
4 Move the playhead to the time when you want the pan to end.
5 Move the image in the Canvas to the ending position.
You don’t need to add a keyframe this time because, once a single keyframe has been
added to a parameter, new keyframes are automatically added each time you move the
clip to a new position.
You should see a line in the Canvas indicating the interpolated motion path between
the starting and ending keyframes.
6 To see the effect, remove the wireframe in the Canvas by choosing Image from the View
pop-up menu, move the playhead to the beginning of the clip, then play the sequence.
