Every motion-grapher is a smart man!
He appreciates the time spent with own family, children or with a friends. And therefore he wants to minimize time at the computer. Due to this purpose were in a world of motion design and animations, created expressions. They are unsightly looking strings which makes the work easier and I want to point out the few top after effects expresions, what are usefull at everytime. These are really the basics and for many advanced operator, this article will become obsolete:
1.) What would it be the world without WIGGLE. 🙂 If you want randomize your position, rotation or any other parameters you always choose wiggle:
wiggle(X,Y)
X represent frequency per second; Y represent amplitude of change. Wiggle(2,100) on the X position will wiggling (smooth randomising) moving object two times per second 100 pixels from default position to both sides.
Example of use: Camera hand shaking
2.) Another always usable is:
time*X
X represents the number multiplied with time. (Time*-25) on rotation means that i can automaticly rotate all the time parameter to negative numbers in speed divided by 25.
Example of use: all linear animations
3.) If you want let some object oscillate in your animation you can use this:
MyValue=-1*Math.cos(time/2*Math.PI*2);
linear(MyValue,-1,1,0,400);
First row give us value of the range -1 to 1. And we use this range in second row and change it to different range from 0 to 400. When we use this expression on position value the object will oscillate by cosine theorem from 0 to 400 in selected axis by speed divided by 2.
Example of use: What about clock pendulum or blinking traffic light?
4.) When you have manually complete difficult animation with keyframes, you can just repeat it by simply:
LoopOut()
Example of use: for all who dont like CTRL+C & CTRL+V 🙂
What is your favorite expression?

Thank you Thank you Greensican: what you say is absolutely true. I am amezad at how often I hear horribly read narrations on million-dollar television commercials. What Tony said about narration and about the narrator is as true today as ever and still not being practiced by most directors. They just do not understand how to tell the voiceover speak to a viewer on a YouTube video for example.David Hoffman Filmmaker Was this answer helpful?
Posted on Hi Brian,I am a friend of Speenberg’s, I was a radio pesianolrty for 25 years and am currently an actor and voiceover artist. I’ve been watching the show since the beginning, and have enjoyed your improvements along the way. I have a home studio, and would like to offer my services as your intro/outro announcer at no charge. You do a great job in that role, but a third voice would stand out more and highlight the two main characters of the show,and be a nice introduction for Brian and Mike‘.If you’d like I will record a demo from your copy so that you can make a decision on how I might add to the overall production value of the Suds and Buds podcast. Just e-mail some copy if you are interested. John Roach
