First lecture in time games section many times when you're doing motion graphic you need to create an
animation and you need to remove it from the screen.
For example here we displayed these two texts.
OK motion graphic is awesome.
They come out from Rockmart.
Each one of them and then we want to remove this one.
Now obviously you can come after some time and start Reekie framing and recreating animation to take
them out.
Or most of the time we want to reverse that animations or bring in text and then we want to take it
out without having to go through the procedure of recreating in another or a different animation to
take out the text in this lecture.
I will explain to you how to use the keyframe assistant to make your life easier and really to speed
up your work by reversing the animation.
So let's look at our keyframes.
First of all if I press you I will see that I have here around 60 frames these keyframes that blink
in the text.
So this is what I will be doing.
I will take this to keyframes.
This is for is awesome.
Copy them.
That is Control-C and then and the timeline indicated for example at two seconds here I will paste them
but of course now I pasted the first frame first and the second frame second.
And this is totally useless.
So it comes in and suddenly you know it's coming in and out twice.
So how do I reverse this keyframes.
Of course what you can do is to bring this one here and this one here right.
And then it will come out.
That's very easy but there is a nicer method that will guarantee you if you have 20 frames then it will
reverse them very easily.
I would select these two keyframes right click on them and go to keyframe assistant and you have time
reverse keyframes and I would just click on it.
Now not this will happen.
The last keyframe the one that was last came in the beginning and the one that was in the beginning
came last.
It means it reversed the keyframe order by keeping all the time you know the time in between identical.
If you come now and describe through you not just now it is just the reverse of the first two keyframes.
Now this is very interesting of course for two keyframes you will say OK I can move them but actually
you shouldn't.
You should always find ways to reduce work on yourself.
Now what I will do I will take the other two keyframes copy them and then come over here for example
and paste them.
Try to make them the same distance.
For example the time in between the one before last and the last one try to make them the same here.
OK.
Just by pasting or by moving the keyframes.
Now the way you would like.
Now our Right-Click again keyframe assistant and say time reverse keyframes.
Now I have both of them coming in and coming out without having to do lots of work.
I can do the same for the last keyframes I will copy Control-C time in the time line for example put
it over here and control the select both of them.
Right click keyframe assistant and say time reverse keyframes.
Then of course you can adjust your keyframes the way you want so that almost identical.
And if you play your animation with de-select it will open and close your own image.
Very fun.
Now that was very good but you notice how I did.
Another way to do it are the same way I would read all this keyframes.
OK I will select them and you did not.
Is that you cannot select all the keyframe blessed Control-C a Contrave you will be duplicating letters.
I will do that.
So you have to do it one layer at a time.
This is the method here I would say Control-C come over here.
Control the this one control C and come over here for example.
Contrave again the last one I will copy them and come over here.
Paste them.
Select all of them.
Right click and go keyframe assistent time reverse keyframes.
Now I reversed all of them at the same time.
I will adjust the last layer here.
And if I'm happy with the pyramid appearance I would leave them the way they are and I can't play you
reverse your keyframes.
Now this is very useful if you have one or two layers and you are doing that you know to the first 10
or 15 keyframes or something like this if you have 10 or 15 keyframes.
But nevertheless if you have very many layers then this is not a method that you want to work with you're
reversing in animation with 10 layers through that method.
Copy paste and so on.
You don't want to do it in the last lecture we learn a better method or I would say a different matter.
Reverse animations.
Let's look at the keyframe assistant reverse keyframes was an exaggerated example for example.
Again take here a rectangle.
Just a simple rectangle Press Control alt in it and home and bring the anchor point in the middle.
Now I want to run it so I will go to window just for this example and being in motion sketch motion
sketch with rock art and animation when I move it on the screen.
We have seen this one in the puppet towards the puppet shows we have seen the motion sketch for the
puppets tools and here we are seeing it for everything.
You know any shape you can do that is ours is just a start capturing.
And I will click and start moving my circle around my square and I say I'm very happy.
From this animation I stop.
If I played back then it's quite nice.
And then I and others are good guys.
When I wanted to start from here I want to start from the bottom with the same motion path.
What would I do.
And this is when the key for my system will become practical you have hundreds of keyframes if you notice
if you press you on the layer you have hundreds of keyframes you don't want to change the motion path
you happy from it.
So how do you reverse that animation.
So your rectangle comes from here what you will do you will select the position keyframes.
All of them.
So you can come to animation for example keyframe assistant and time reverse keyframes and now your
rectangle is coming from the other side.
You have reversed the time for all these keyframes.
The first became last and the last became first and so on and you reversed your animation.
So this is the use of the D frame assistant a time reversed keyframe.
It's very important that you learn about it and it has a lot of you know usefulness sometimes when you're
doing mainly I would say transitions or you know Title animations are fine.
Thanks very much for listening.
I will see you in the next lecture.
Where we learn another method to reverse our emissions.
