Hello I am wondering what is the difference between Smooth, Linear, Ease In/Out, Ease In, Ease Out, Bezier, Step, Noisy, Cycle, Bounce, and Elastic keyframe options?

Like what do all of these do? I usually use default smooth and I prefer that option. I also see a lot of people use linear... So I want to know mostly the difference between smooth and linear... I would also like to know about the others as well... I have wondered this for a while. I did try linear but I couldn't see the difference at all.. So can anyone explain to me what are the differences between all of these keyframe options?

You need to learn the principles of animation first, specially timing and spacing.

I have version 9.5 of Pro and the page numbers may be different depending on the version you are using. In the manual pages 258-261 there is a brief description of interpolation options.

Smooth: Takes into account neighboring keyframes, creating a smooth transition from one keyframe to the next.
Linear: Moves an object in a straight line, with no acceleration or deceleration from one keyframe to the next.
Ease In/Out: Creates a smooth transition at the beginning and the end.
Ease In: Creates a smooth transition at the beginning.
Ease Out: Creates a smooth transition at the end.
Bezier: Allows you to use Bezier handles to shape an • animation curve.
Step: Holds an object, unmoving, at the previous keyframe’s position until the next keyframe is reached. Then it suddenly jumps (or steps) to the new position.
Noisy: Can be used to simulate a handheld camera, but it can be used to interpolate any value. It adds jitter to the interpolation process so that the object appears wobbly from one keyframe to the next.
Cycle: Cycles back to a specific frame number (absolute cycling), or back by a specified number of frames (relative cycling).

I don't have Bounce, Stagger or Elastic but the options are fairly evident in the names lending those characteristics to their behavior.

"Bounce, Elastic and Stagger Interpolation
NEW in Anime Studio Pro 10 - By applying the Bounce keyframe type to the timeline, any object interpolated will appear to bounce, all within two keyframes. Elastic provides a rubber band effect, making objects spring back and forth before reaching their end point. Settings can be adjusted for each of these interpolation types to change the amount of times the object bounces, the intensity and more. Stagger creates the effect that the animation is stuttering or staggering between two keyframes. No additional keyframes are created for this effect. This is great if you want to create the effect a character is having issue lifting a heavy object, as an example. [Pro Only Feature]"

To the original poster, thanks for asking this, and also to Ampy thanks for answering. I just discovered this myself.

Another great way to learn these things is to just go in and try each and see what they do. A description is nice, but actually seeing it may inspire something creative in you.

I once made a test with number of circles stacked vertically that moved across the screen at the same time. Each circle had a different option. I tried it again with onion skins.

That's a good idea 3deeguy, how did that work out for you?

It worked very well. Creating a 48 frame cycle and watching what happens is an excellent way to learn the app.
