Each frame in an animation defines how long it is displayed when the animation is played. The animation editor allows editing the frame time to speed up or slow down individual frames or the entire animation.
To change the amount of time that an individual frame is displayed in an animation:
Select a frame in the animation
Find the FrameLength property
Change the value to the desired length in seconds
The entire length of an animation can be changed without manually changing each individual frame. To do this:
Right-click on the desired animation
Select Adjust All Frame Time
Enter the new desired length of the animation
(Optionally) select the desired option for changing the frame time. The frames can be adjusted to all have the same value, or can be adjusted proportionally to achieve the desired animation length
