Animation within Edge Animate
There are many applications which enable the user to compose animated sequences. Users of Adobe Edge Animate may
have experience in other programs such as Director, Flash Professional, After Effects, or even Photoshop. All of these
applications handle animation in slightly different ways, but they do all share some aspects of animation techniques and
tooling in common as well.
Like many digital animation programs, Edge Animate employs the concept of "tweening" between keyframes. In
t
ra
ditional cell-based animation, a master animator would draw out certain key frames for an animation sequence, and
the frames in between these key frames would be created by apprentice or lower-ranked members of the animation
team. The goal was always to create a smooth transition between each key frame created by the master animator, which
would result in a completed animation sequence.
This process is performed programmatically within Edge Animate. As keyframes are placed along the Timeline, Edge
A
nim
ate will record changes in property values as transitions at the position of the Playhead (moment in time). As
authors, we have the additional ability to provide the tweening engine with instruction sets based upon a variety of
easing equations. This allows a more natural flow between keyframes, and can also be used to achieved certain effects
such as an elastic or bounce motion.
The Edge Animate Timeline
The Timeline is where all of the motion in an Edge Animate composition is orchestrated. The Timeline itself shares
concepts and constructs from other Adobe applications, most notably Flash Professional and After Effects.
Note: Unlike the frame-based timeline in Flash Professional, the Edge Animate Timeline is purely time-based.
Playback controls
The playback controls in Edge Animate are all grouped together in the upper-left corner or the Timeline panel. These
controls allow quick access to many of the playback options available through the Timeline.
Time
The time in Edge Animate is measured in standard decimal time code format (mm:ss.ddd), and this is how it is
displayed in the Time control. As the Playhead moves along the Timeline, the information in this display is updated
accordingly. A user can scrub the control to the left or right to adjust the current time, or simply click on it—making it
editable.
