User Manual

Dragging on a keyframe’s handles adjusts the slope of the segments passing through the
spline. By default, the two control handles on a control point are locked together so that if one
moves, the one on the other side moves with it. This maintains a constant tension through the
keyframe. There are situations, however, when it is desirable to modify these control handles
separately for a more pronounced curve or effect.
To temporarily break the control handles on a Bézier spline, moving one
independently of the other:
1 Select the control point to be modified.
2 Hold down the Command key and drag one of the control handles. They will now move
independently of each other, as long as the Command key is held down.
To treat all Bézier handles as independent in the Spline Editor:
 Right-click in the graph and choose Independent Handles from the
Options contextual menu.
Enabling this option causes all the Bézier handles to be independent. This is the same as using
the Command key when moving a handle, except it is applied to all control points until it
is disabled.
Reducing Points
When there are too many control points too close together on a spline, you can choose Reduce
Points to decrease their number, making it easier to modify the remaining points. The overall
shape of the spline is maintained as closely a possible while eliminating redundant points from
the path.
To reduce the number of points on a spline:
1 Select the range of keyframes you want to thin out.
2 Right-click in the graph area and choose Reduce Points from the contextual menu.
3 When the Reduce Points dialog appears, drag the slider to a lower value.
You can set the slider value as low as possible as long as the spline still closely resembles the
shape of your original spline.
TIP: When the value is 100, no points will be removed from the spline. Use smaller
values to eliminate more points.
Filtering the Spline Editor
The animation splines for multiple parameters can be displayed within the Spline Editor
simultaneously, and Fusion offers several ways for you to choose which spline to view and
which to edit.
A complex composition can easily contain dozens, if not hundreds, of animation curves. As a
composition grows, locating a specific spline can become more difficult. There are two ways to
filter the splines shown in the Spline Editor: display selected tools only or create a filter to show
only certain tools.
