Making Animated Web Content

The timeline is where the bulk of the animation process takes place. This is where you control the speed at which a movie element moves when it enters and exits the scene, and its depth, or stacking order, in relation to other elements in the scene.

The Timeline shows where animation occurs in a document, which includes frame-by-frame animation, tweened animation, and motion paths.

Controls in the layers section of the Timeline let you hide, show, lock, or unlock layers, as well as display layer contents as outlines. You can drag Timeline frames to a new location on the same layer or to a different layer.

Timelines in Adobe Flash Professional CS5 contain static and tweened content, which both look and behave differently on a timeline. By default, the Timeline appears below the main document window. To change its position, detach the Timeline from the document window and float it in its own window or dock it to any other panel you choose.

To change the number of layers and frames that are visible, resize the Timeline. To view additional layers when the Timeline contains more layers than can be displayed, use the scroll bars on the right side of the Timeline. To move the Timeline when it is docked to the document window, drag the title bar tab at the upper-left corner of the TimelineTo dock an undocked Timeline to the application window, drag the title bar tab to the top or bottom of the document window.

To dock an undocked Timeline to other panels, drag the Timeline title bar tab to the location you choose. To prevent the Timeline from docking to other panels, press Control while you drag. A blue bar appears to indicate where the Timeline will dock. To lengthen or shorten layer name fields in the Timeline panel, drag the bar separating the layer names and the frames portions of the Timeline Customizing the Timeline view

If the Timeline is docked to the main application window, drag the bar separating the Timeline from the Stage area. To get more information Click Here.

Onion skinning

Do one of the following:

  • Select the Onion skin icon, the icon to the left of the Loop icon, in the Timeline. All frames between the Start Onion Skin and End Onion Skin markers are superimposed as one frame in the Document window.
  • Select to display onion skinned frames as outlines.

The red playhead at the top of the Timeline moves as a document plays to indicate the current frame displayed on the Stage. The Timeline header shows the frame numbers of the animation. To display a frame on the Stage, move the playhead to the frame in the Timeline.

To display a specific frame when you’re working with a large number of frames that can’t all be displayed in the Timeline at once, move the playhead along the Timeline.To go to a frame, click the frame’s location in the Timeline header, or drag the playhead to the desired position.

To center the Timeline on the current frame, click the Center Frame button at the bottom of the Timeline.With the “loop” option turned on in the timeline, you can now loop streaming audio within a range of frames along with other animations.

Keyframes and property keyframes are locations on a timeline where you either define a new copy of an object or changes to the properties of a motion-tweened object. A keyframe represents a new instance or copy of an object, such as a new instance of a movie clip symbol. A keyframe is represented by a solid dot. When you create a frame-by-frame animation, most frames are keyframes because you’re creating new content in each frame to create the illusion of movement.

When you create a motion tween, every tween span has a single target object for the entire duration of the tween span. Therefore, the keyframe is always at the first frame of a tween span. Further changes on that tween span are called property keyframes, since they are not copies of an object, but instead, represent changes to individual properties of the same object.


The difference between property keyframes and traditional keyframes is how they relate to the properties of an object. In Flash, an object has properties like x position, y position, width, height, and rotation. A traditional keyframe is actually a full copy of an object. That copy has an x,y value as well as a width and height, so the keyframe contains a value for all of the object’s properties.


When you create a motion tween, the layer state changes to a tween layer. Any layer that has a tween span on it changes to a tween layer. A tween layer can hold tween frames and blank or empty frames. To get more information Click Here.
