Easing presets are not affecting animation

Easing on a keyframe controls the transition out of that keyframe towards the next one. Applying it to the keyframe where the motion arrives changes the transition after it, not the one you were watching — this single rule explains most "easing does nothing" reports.

Symptoms

If one or more of these match what you are seeing, you are on the right page.

  • •The preset is applied but the motion still looks linear
  • •Easing affects the segment after the one you intended
  • •The last keyframe’s easing appears to do nothing
  • •Only one property eases when several were selected

Causes and fixes

Ordered from most to least likely. Work down the list — each cause is paired with what to do about it.

  1. 1

    The easing is on the wrong keyframe.

    Easing applies to the outgoing transition. The keyframe where motion starts controls the acceleration away; the keyframe where it ends controls the deceleration arriving. Apply the preset to the keyframe the motion leaves.

  2. 2

    Easing was applied to the final keyframe.

    The last keyframe has no following transition to govern, so its easing has no visible effect. Apply it to the preceding keyframe instead.

  3. 3

    Only one track was selected.

    Easing is per property track. Select the keyframes on every track that should share the curve, then apply — or use the bulk shortcuts F9, Ctrl+F9, Shift+F9 and Ctrl+Shift+F9 across a multi-track selection.

  4. 4

    The keyframes are Hold type.

    Hold keyframes have no interpolation at all, so no easing curve can apply. Right-click and toggle them back to standard keyframes.

  5. 5

    The two keyframes have the same value.

    Easing shapes the velocity of a change. With no change in value there is nothing to accelerate — check the values differ.
