Solution 1Recommended

Apply a Motion Path Animation

Easing options like Smooth Start and Smooth End are not universally supported by all animations; they primarily work with Motion Paths.

PowerPoint restricts easing controls to animations that involve movement across the slide. Standard entrance or exit animations (like Fade or Appear) do not support easing because they do not have a travel duration. To unlock the Smooth Start and Smooth End sliders, you must change your animation to a Motion Path.

1
Select the object

Click on the image, shape, or text box on your slide that you want to animate.

2
Apply a motion path

Navigate to the 'Animations' tab on the top ribbon, open the animation gallery, scroll down to the 'Motion Paths' section, and select an effect like 'Lines' or 'Custom Path'.

3
Open Effect Options

Click 'Animation Pane' in the ribbon. In the pane that appears on the right, double-click your new animation (or right-click and select 'Effect Options').

4
Adjust easing sliders

In the Effect Options dialog box, the 'Smooth Start' and 'Smooth End' sliders will now be active. Drag the sliders to assign the desired easing duration.

Apply a Motion Path Animation
Total Animation Duration: The combined time of your Smooth Start and Smooth End cannot exceed the total duration of the animation.

Frequently Asked Questions

Why are timing options grayed out for standard entrance animations?

Basic entrance and exit animations (like Fade, Wipe, or Appear) do not involve physical movement between two coordinates on the slide. Because easing controls (Smooth Start/End) dictate acceleration and deceleration over a distance, they are strictly designed for Motion Paths.

Does the 'Bounce End' effect work with all animations?

No. Similar to Smooth Start and Smooth End, the Bounce End effect is typically only available for Motion Paths and a select few entrance effects (like Fly In) that involve directional movement across the slide.

How do I fix animations that won't play on my Mac?

Ensure that your animation triggers are set correctly (e.g., 'On Click' or 'With Previous'). If an animation is set to trigger on a click but is attached to an object that isn't clickable during the slideshow, it may appear as though it is not working. Check these settings in the Animation Pane.
