This year guys you could say is a continuation of the previous lecture.
We are still in time for speed and we are using this PDA now.
I want to show you how to use the negative values and what's the concept behind this select display
and press control the comment the on the Mac and duplicated and less press you to see the key frames
and actually delete all the key things.
So let's hide the bottom layer and then we want to work on this that with the negative speed.
If you go from 50 you can take it down to let's say minus nine.
If you play nothing is playing.
Why is that.
Well after effect is going to take the position on this frame and go backward minus 109.
But you are at 3 zero at the beginning of the video.
So it's not possible for him to go back from 0 5.
So the solution to that is for example let's write a 500 and the keyframe it.
OK.
So we are at a very high speed here.
I will also use here the whole keyframes.
OK.
So it's better.
We can see what's happening.
Let's scan for example after two seconds.
OK.
So actually we have played two seconds at 500 frames.
So we are almost at 1000 frames.
I will change the speed now to minus 500.
And as as you expect is going to go see forward and backward.
When will it stop when it will reach the frame.
Or frame 1 if you like.
So there is no more frames to go backwards so it will stop over here just here.
Now we are at the beginning of the video which is this speed for example to 250.
So it's going quite speedy come after eight seconds.
OK.
So 250 now times of four seconds you have spent already.
Thousand frame then you change a value for example to minus 500.
And here you are you have a nice back and forth video that you can play with.
Of course this is a bit naive but it's up to you to tweak it to make it nicer and to create some nice
animation over here.
Maybe also using normal keyframes.
You can also remember is it is I will toggle back and you can select your keyframes.
If 9 to easy is and come back over here to the glove chart.
Let's say we are in the speed chart and play with your keyframes the way you will want.
You will get a certain animation.
So there is a lot of testing but not much to show you know.
I'm just going to show you how to work with them.
It's something you already know.
Let's go back and select all of them and toggle them back to hold keyframes.
Now let's try the famous motion blur here.
The motion blur here will use the method.
If this whole frames frameworks or picks and motion I'm going to put it at framework's.
So it's going to have this ghosting.
Plus the motion blur for now leave it to automatic.
And let's play and see exactly what's happening.
It's a very cool effect here a bit exaggerated of course just for the course.
Now we know this here you have five shadows.
Let me go back just one.
I would go pick up your notes you have five shadows.
This is coming from the shot of sample.
How many shallows you want to see or how many times you want the shutter.
You put it at two and you get two of them which is pretty interesting by the way.
OK.
And of course you can keyframe the shattered sample create more or less and play around with it.
Let's try.
This come to this keyframe and the keyframe the shot that simple let's go backward we go J and we put
five.
OK let's see the difference come back to the beginning play.
So now you are at 5 and you go backward with five.
Now you are at 2.
It's about you what you want to create and how you want to create it.
I showed you here and there is a lot of Creation to play around with.
OK guys.
So I hope this was first of all fun for you.
And second Get your own video.
It's like you're walking backwards or forward and then you move faster and slow or even you make it
negative speed here something like this you know create something uploaded to youtube post your link
in the Q and A section of the course.
I will be very happy to see your work and give you some good comments if you like.
Thank you for listening.
I will see you in the next election.
