Easy Ease vs Ease In vs Ease Out in After Effects Explained

Understanding easing is fundamental to making animations feel natural rather than robotic. Here's the breakdown:

Linear (default): Constant speed from A to B. Looks mechanical and unnatural — almost never what you want for organic motion.

Easy Ease (F9): Slows down at BOTH the start and end of the movement. The object gently accelerates, moves, then gently decelerates. Think of a car pulling away from a stop sign and then stopping at the next one.

Ease In (Shift+F9): Starts slow, then accelerates INTO the keyframe. Use this on the LAST keyframe of a movement — the object is "easing in" to its final position. Think of a ball falling — it starts slow and gets faster.

Ease Out (Ctrl/Cmd+Shift+F9): Starts fast, then decelerates OUT of the keyframe. Use this on the FIRST keyframe — the object is "easing out" of its starting position. Think of throwing a ball upward — fast at first, then slows.

The confusion: The naming is counterintuitive. "Ease In" doesn't mean "ease into the motion" — it means the speed curve eases IN to that specific keyframe point.

My recommendation:
- Start with Easy Ease on everything (select keyframes → F9)
- Then open the Graph Editor to customize the curves
- For snappy motion design, use aggressive ease-out at the start (fast departure) and aggressive ease-in at the end (soft landing)
- The Graph Editor is where the real magic happens — Easy Ease is just a starting point

Pro tip: Select your keyframes, hit F9 for Easy Ease, then go into the Graph Editor and pull the handles to around 75-85% influence for that satisfying motion design snap.
