You can view frames in the Animation key editor. You can add or delete frames to increase or decrease the length of an animation or a part of an animation. For example, if part of an animation is too erratic, you can add frames between the two frames where the problem exists to refine the problem area. Similarly, if the export size of an animation is too large, you can delete frames from the animation to decrease the size.
