We still have two options within the work area.
The left work area and the duct work area you need to learn these ones and keep them in mind.
They are actually very practical when you are doing video editing.
Let me give you an example.
Let's start with the work area lift.
I created the composition from the old times because it's 14 seconds and let's say from four seconds
ok to eight seconds and I want this portion I want to remove it.
So the way to work about it is to go to four seconds.
Here you are and then you bring the beginning be to the timeline indicator go to eight seconds.
And then of course press and to bring the work area and to the time indicate if you right click you
have the option to leave the work area when you're left in video editing.
It means you delete but to keep this space.
OK we agree on that.
Lifting is deleting and keeping the space.
Here is the option.
You're not sure what happened here.
It has deleted all the contents of the layers but the space has remained.
So the content has been deleted removed totally but the space has become blank.
You know you're seeing the background here of the composition and the layers had been split to make
this editing possible.
OK.
You cannot in After Effects delete a portion of a layer.
This is not video editing.
In fact you cannot put clips like this on the same layer.
This is compositing.
So you need to keep players on top of each other.
So this is the object of the lift is to remove the content and keep the space for the determined work
area.
Now let's see what work area does.
OK I have two layers here to give you a better example.
Now if you are right click and go extract work area.
What will happen is first of all it will lift everything meaning it will delete all the content within
the work area.
So you delete everything from four to eight seconds that's just like lift.
But then it will take whatever is remaining on the right side and move it to the left.
That is the job of extract and sometimes is extremely useful.
So without selecting any layers you just right click and you say extract so that is exactly what happened.
First of all the layers have been split of course and then the content within the work area has been
deleted.
If you click on this one like this and take it back you will notice what ever was from this player.
Old times under the work area was deleted.
And then what it was from the end of the work area to the end of the composition was shifted to the
left.
OK guys so now we have covered the trim camp the extract and the leaf.
Please keep them in mind because later on when projects become very big you know how to use them and
this lecture would be a great reference for you.
Thank you.
I will see you in the next lecture.
