I guys and welcome to this new section in this section we are going to learn about expressions.
I will demonstrate you how to use expressions.
The concept of expressions and how to do certain graphics with expressions that are pretty interesting
expression are used to reduce the work and to do certain animations that don't require keyframes of
course expressions will reduce the number of keyframes in a terrible way up to zero if you want.
So we will go through some difficult expressions and some simple expressions.
What is important here is not to learn all the expressions it's to learn the concept of expression the
concept of referencing and how to pick values how do you use the whip in the right way.
That's what we're doing in this section.
The thing that we will not be doing is trying to write a javascript script more programs or scripts.
We are not going to learn how to use these script because script is a language javascript and is not
given to everybody to learn that language.
And when you are raising after effects you don't want to use javascript and to learn scripts write scripts.
That's not necessary.
You can always go to very many sites that will give you a ready made scripts that you can use.
But it's important that you learn how to change the scripts sometimes and how to understand how after
effects uses expressions.
So let's dive in in this section and I hope you learn a lot if you have any questions you know very
well.
You can post your questions in the queue any section of this course and it will be very happy to answer
to you.
Let's move on to the first lecture.
