Frames and keyframesContents [Hide]Like films, Adobe® Flash® CS4 Professional documents divide lengths of time into frames. In the Timeline, you work with these frames to organize and control the content of your document. You place frames in the Timeline in the order you want the objects in the frames to appear in your finished content. A keyframe is a frame where a new symbol instance appears in the Timeline. A keyframe can also be a frame that includes ActionScript® code to control some aspect of your document. You can also add a blank keyframe to the Timeline as a placeholder for symbols you plan to add later or to explicitly leave the frame blank. A property keyframe is a frame in which you define a change to an object’s properties for an animation. Flash can tween, or automatically fill in, the property values between the property keyframes in order to produce fluid animations. Because property keyframes let you produce animation without drawing each individual frame, they make creating animation easier. A series of frames containing tweened animation is called a motion tween. A tweened frame is any frame that is part of a motion tween. A static frame is any frame that is not part of a motion tween. You arrange keyframes and property keyframes in the Timeline to control the sequence of events in your document and its animation. Insert frames in the Timeline
Select frames in the TimelineFlash offers two different methods for selecting frames in the Timeline. In frame-based selection (the default), you select individual frames in the Timeline. In span-based selection, the entire frame sequence, from one keyframe to the next, is selected when you click any frame in the sequence. You can specify span-based selection in Flash Preferences.
Specify span-based frame selection
Copy or paste a frame or frame sequence Do one of the following:
Delete a frame or frame sequence Select

desired location.Change the length of a static frame sequence Control-drag (Windows) or Command-drag
(Macintosh) the beginning or ending frame of the span to the left
or right.To change the length of a frame-by-frame animation sequence, see Create frame-by-frame animations. Convert a keyframe to a frame Select the keyframe and select
Edit > Timeline > Clear Keyframe, or right-click (Windows)
or Control‑click (Macintosh) the keyframe and select Clear Keyframe
from the context menu. The Stage contents of the cleared keyframe and all frames up to the subsequent keyframe are replaced with the Stage contents of the frame preceding the cleared keyframe. |
