Start with the Motion Dock open and a composition containing a layer you can animate.

Add Curvy

  1. Click Edit layout in the Motion Dock.
  2. Click an empty area of the layout and choose Curvy.
  3. Click Exit layout mode.

If Curvy is already in the current layout, use its existing slot.

A fresh Curvy starts with Smooth held in the card. The small curve tiles are favorites.

Copy reads selected keys. Apply changes their easing.

Ease a fade

  1. Create an Opacity key at 0% and another at 100%, about a second apart.
  2. Select both keyframes in the timeline.
  3. Click Apply in Curvy.
  4. Preview the composition.

The layer should fade in slowly, move faster through the middle and slow down into 100%. The keys keep their original times and values. Undo in After Effects restores the previous easing in one step.

Adjust the feel

Drag anywhere inside the curve card. The nearer handle moves with your pointer. Release to keep the new shape.

With the default Apply as you edit setting, releasing the drag also updates the selected keys. Preview the fade again to see the change. Shape a curve explains the handle gestures.

If Apply reports No keys, select the keyframe diamonds themselves. Selecting a layer alone is not enough. If it reports Locked or Hold keys, use an unlocked layer with non-hold keys for this first try.
