A keyframe is a frame where you define changes in the animation. When you create frame-by-frame animation, every frame is a keyframe. In tweened animation, you define keyframes at important points in the animation and let Flash create the content of frames in between. Flash displays the interpolated frames of a tweened animation as light blue or green with an arrow drawn between keyframes.
Keyframes appear within a frame as a solid circle. Empty keyframes appear as hollow circles. The first frame in every layer is automatically a keyframe. The contents of a keyframe appear in new frames that you add to a layer.
To create a keyframe:
Do one of the following:
|
Select a frame and choose Insert > Keyframe. |
|
Right-click (Windows) or Control-click (Macintosh) a frame in the Timeline window and choose Insert Keyframe. |
To create a series of keyframes:
Select a range of frames and choose Insert > Keyframe.
