## Exploring After Effects speed graph

This week, we talk about motion animation and object-oriented concept in After Effects. With a motion library that have been built already, we need expand our own motion while

#### Types of Keyframe

Basically, there are five kinds of keyframe in After Effects and they all show different symbols in the graph.

• Hold keyframe: It holds the value and change immdeiately.
• Linear keyframe: It change the value linearly.
• Easy-ease keyframe: It applies easy-ease to speed curve. It mainly use for speed and timing rather than position.
• Auto Bezier: It creates a smooth rate of change through a keyframe. It mainly uses for spatial change. For example, you could use it to cover the path or car into curving road. It will also effect the previous and next keyframe.
• Continuous Bezier: While auto bezier is used to automatically adjust the change as smooth as possible, you could still adjust manually and it will turn into continuous Bezier.

#### Menu bar in the buttom of graph

I also look through the options in the bottom of graph.

a. Show: Refer to the second figure. You could either choose to Show Animated/Selected Properties.

b. Graph information: Refer to the third figure. Most of time, you could use Edit Value Graph or Edit Speed Graph.

c. Snap: While adjust the point in the curve, by enable this function, After Effects will help you snap to nearby point.

d. View: From left to right are Auto-zoom graph height, Fit selection to view and Fit all graphs to view.

e. Keyframe options: From left to right are, Edit selected keyframes (submenu includes all options), Hold, Linear, and Auto Bezier.

f. Easy-ease: From left to right are, Easy-Ease, Easy-Ease In and Easy-In Out.

#### Align with motion library

After further investigating the configuration of speed grah, I decide to make some motions align with zoom. The largest white circle is using the built-in curve, while others are slight modified and shifted. Just notice that next one can’t reach the maximum until previous one do.
