[. . . ] All keyframes are removed for that parameter. m Chapter 6 Keyframes and Curves 417 Animation Menu States Depending on whether or not a parameter is currently animated, and whether or not the playhead is positioned on a keyframe, the Animation menu displays a different icon. This provides the ability to determine the status of that parameter at a glance. Keyframed parameter Parameter is not animated Behavior applied to parameter Keyframed parameter with keyframe at current frame The Reset Button Each parameter set in the Inspector is equipped with a Reset button. A parameter set might be a filter, or it might be a category of effects or transformations, such as Transform, Blending, or other items in the Properties tab. Reset button The Reset button removes all keyframes applied to all of the parameters within the set and restores those parameters to their default state. 418 Chapter 6 Keyframes and Curves Animating in the Timeline When keyframing, it is often very helpful to view your keyframes over time. This lets you line up keyframes with other important timing elements in your project such as edit points, sound cues, markers, and even other keyframes. These functions are available in the Timeline. Keyframes In order to view your keyframes in the Timeline, you must first turn on the Show Keyframes option. To show keyframes in the Timeline: Click the Show/Hide Keyframes button. m Show/Hide Keyframes button Chapter 6 Keyframes and Curves 419 You can identify a keyframe's value in the shortcut menu. Multiple keyframes on the same frame are all listed in the menu. m To find a keyframe's value: Control-click the keyframe. The first items in the list are the keyframe values for any keyframes on that frame. Note: There is no way to add keyframes in the Timeline. Modifying Keyframes in the Timeline When keyframes are visible in the Timeline, you can change their positions in time by dragging them horizontally in the track. This does not modify the keyframe's parameter value, it just changes the position in time when it occurs. To move a keyframe in the Timeline: 1 Click the Show/Hide Keyframes button in the Timeline. 3 Drag the keyframe to the left or right to move it forward or backward in time. Although moving a keyframe in time does not change the parameter's value, it can have a significant effect on the nature of the animation. For example, if you have two keyframes that animate an object from the top of the screen to the bottom over five seconds, moving one of the keyframes forces the animation to occur more slowly (if you drag them farther apart) or more quickly (if you drag them closer together). Aligning Keyframes With Other Elements One of the main advantages of manipulating keyframes in the Timeline is the ability to line up a keyframe with another important time marker. For example, you may want to align a filter keyframe applied to one object with an object occurring on another track. To align a keyframe to another object: 1 Click the Show/Hide Keyframes button in the Timeline. 2 Identify the keyframe you want to move. 420 Chapter 6 Keyframes and Curves Note: Control-clicking a keyframe displays a shortcut menu containing the parameter name and value for each keyframe. If more than one keyframe is at the same point in time, the shortcut menu lists all of them. If you press the Shift key while you drag, the keyframe snaps to the edges of other objects. You can use this same technique to align keyframes from one object to keyframes in another object. In this way, you can arrange two objects to both fade in or blur into focus at exactly the same frame. It doesn't matter whether the objects are in the same layer or not. [. . . ] The green dot represents the start of the gesture, the blue arrow is the direction of your gesture, and the red dot the end of the gesture. Draw the gesture on the tablet, with your pointer in the Motion Canvas or Timeline. Direction of movement Gesture start position Gesture end position Modifier Keys Many gestures have additional functionality when used in combination with a key on the keyboard. In the following tables, if a gesture has an entry in the Modifier keys column, it has additional functionality that is accessed by using a shortcut key. For example, if you have the Control key set as the gesture trigger, and you draw the play forward gesture, the project plays forward from the current time. [. . . ]
