To create a frame-by-frame animation, you define each frame as a keyframe and create a different image for each frame. Each new keyframe initially contains the same contents as the keyframe preceding it, so you can modify the frames in the animation incrementally.
Click a layer name to make it the active layer, and select a frame in the layer where you want the animation to start.
If the frame isn't already a keyframe, select Insert > Timeline > Keyframe to make it one.
Create the artwork for the first frame of the sequence.
You can use the drawing tools, paste graphics from the Clipboard, or import a file.
Click the next frame to the right in the same row and select Insert > Timeline > Keyframe, or right-click (Windows) or Control-click (Macintosh) and select Insert Keyframe from the context menu.
This adds a new keyframe whose contents are the same as those of the first keyframe.
Alter the contents of this frame on the Stage to develop the next increment of the animation.
To complete your frame-by-frame animation sequence, repeat steps 4 and 5 until you've built the motion you want.
To test the animation sequence, select Control > Play or click the Play button on the Controller.
