Fine-tuning Animation
To retract both Bezier direction handles:
1 Select the Convert Control Point tool ( ) from the toolbox.
2 On a Value graph or motion path, click the keyframe.
To extend retracted Bezier direction handles:
1 Select the Convert Control Point tool ( ) from the toolbox.
2 On a Value graph or motion path, click the keyframe and drag outward from the
keyframe.
To toggle between the selection tool and the pen tool:
Hold down Ctrl (Windows) or Command (Mac OS).
Mixing incoming and outgoing interpolation methods
By default, a keyframe icon uses one interpolation method, but you can apply two methods:
the incoming method applies to the property value as the current time approaches a
keyframe, and the outgoing method applies to the property value as the current time leaves
a keyframe. When you set different incoming and outgoing interpolation methods, the
keyframe icon changes accordingly. It displays the left half of the incoming interpolation
method icon and the right half of the outgoing interpolation icon.
You can freely mix Linear and Bezier interpolation methods using the Speed or Velocity
graph. See “Fine-tuning speed” on page 215. Because Auto Bezier interpolation automat-
ically adjusts both incoming and outgoing direction handles, once you mix Auto Bezier
with another method, the original half of the keyframe becomes Bezier.
To mix Bezier and Linear interpolation methods:
1 In the Timeline window, select the Bezier or Linear keyframe you want to change.
2 Expand the layer outline to display the Speed or Velocity graph for the layer property
containing the keyframe.
Note: Make sure that you adjust the handles on the Speed or Velocity graph, not the Value
graph. See “Factors affecting speed” on page 211.
