To slow down a clip's motion at the beginning and speed it up as it nears the next keyframe: m Drag the velocity handle away from the selected keyframe. Drag away from the keyframe to slow down the motion of the clip at the beginning, and then speed it up as it nears the next keyframe. To add Bezier handles to a keyframe and change the acceleration: m Control-click a keyframe, then choose an option from the shortcut menu, depending on the kind of acceleration you want. Two commands in the shortcut menu let you manipulate acceleration on a motion path. Â Ease In/Ease Out: Curved keyframes are created with the velocity handle set for motion to begin slowly, and then speed up over time, as the clip moves from that keyframe to the next one on the motion path. Â Linear: Curved keyframes are created with the velocity handle set to provide a steady rate of speed as the clip moves from that keyframe to the next one on the motion path. Note: Both commands create Bezier handles with the same controls. Important: The velocity at which clips speed up into or slow down out of keyframed motion in the Canvas has no effect on the overall speed of the clip's motion. 742 Part IX Effects
