I've started using Motion Tweening in CS4 and I am puzzled by something with how the durations are set. The best way I can describe this is by comparing it to what are now called Classic Tweens…
In a Classic Tween, I set the beginning and end keyframes of a particular animation, and when the playhead reaches the ending keyframe, the animation stops…
In a CS4+ Motion Tween, I set the first keyframe and then make changes using the motion editor, but when I add frames to the timeline, the tween keeps on growing, and the animation doesn't stop correctly. Is there some trick to telling the Motion Tween that it should only be X amount of frames?
