Setting Keyframes Manually 133

6 Click the keyframe at 5:00 to select it, and then drag the Bezier handle to the left to

make it longer and flatten out the curve coming into the keyframe.

NOTE

If you do not see a bezier handle extending from the keyframe when you

select it, Command-drag left on the keyframe to create one.

Be careful not to pull the Bezier handle down, or the curve may dip below the

keyframe value and the curtains will start to close again before opening fully.

7 Click the keyframe at 0:00. Adjust the Bezier handle to create a steeper curve and,

therefore, faster initial movement. Play the project to see the results of your changes.

Currently, the animation starts at 0:00 because keyframe recording automatically added a

keyframe at the start of the layer. But what if you want the curtains to stay closed for the

first second to build a little suspense? Setting keyframes manually gives you the most cre-

ative control.

Setting Keyframes Manually

In addition to recording keyframes, you can manually set keyframes, whether or not

recording is enabled. Manually setting keyframes is a great solution when you want to

lock in an existing value at the current frame. (Recording requires you to change the value

to create a keyframe.)
