Create Bezier keyframes
1. In a Timeline panel, select the clip containing the keyframes you want to adjust, and then do one of the following:
(Timeline panel) Choose the property you want to adjust from the effect menu next to the clip or track name. You adjust the temporal
interpolation of a property in a Timeline panel. Select the clip in the Program Monitor if you want to change the spatial interpolation there.
(Effect Controls panel) Select an effect property’s keyframe markers for the keyframes you want to adjust.
2. Do one of the following to choose a keyframe interpolation method:
(Timeline panel) Right-click the keyframe you want to adjust, and choose a keyframe interpolation method from the menu.
(Effect Controls panel) Right-click the keyframe marker for the keyframe you want to adjust, and choose a keyframe interpolation method
from the menu.
3. To manually change a keyframe from one type to another, do one of the following:
If the keyframe uses Linear interpolation, Ctrl-click (Windows) or Command-click (Mac OS) the keyframe in a Timeline panel or Ctrl-click
(Windows) or Command-click (Mac OS) the keyframe marker in the Effect Controls panel to change it to Auto Bezier. If you drag the
handles, the keyframe changes to Continuous Bezier.
If the keyframe uses Auto Bezier interpolation, Ctrl-click (Windows) or Command-click (Mac OS) the keyframe and drag out a direction
handle to change it to Bezier. Bezier interpolation lets you control each direction handle independently. To convert it to Continuous
Bezier, just drag a handle.
If the keyframe uses Bezier, Continuous Bezier, or Auto Bezier, Ctrl-click (Windows) or Command-click (Mac OS) the keyframe to
change it to Linear. The Bezier handles disappear.
Adjust Bezier handles
1. Display the Bezier keyframe you want to adjust.
2. Select either the Selection tool or the Pen tool , and do one of the following:
To adjust the slope of the curve, drag the Bezier handle up or down. Moving the handle up accelerates the changes and moving the
handle down decelerates the changes.
To adjust the range of the curve’s influence, drag the Bezier handle to the left or right.
Fine-tune the speed of an effect
In the Effect Controls panel, you can use the Velocity graph to adjust motion or the rate of change for a value just before and just after a keyframe.
Such adjustments can simulate real-world motion. For example, you can change the motion of a clip so that it slows down just before a keyframe
and then speeds up just after the keyframe. You can control the values approaching and leaving a keyframe together, or you can control each
value separately.
