In this lecture we want to work with Time Warp.
So let's doubleclick on the composition.
Open it and we have our nice movie here.
We are already working with this video and we have the swinging bulbs.
So it's a quite a good demonstration with this video.
Now aren't you stretch your imagination and show you for this video.
Because I start imagining what you can do with other videos that you shot at home at work or even professionally
what you can do with them and what kind of skills you can develop and expand really your imagination.
So first of all we have the composition here that is 25 frames per second and our video also if we come
to bulb's dancing bulbs we also have 25 frames per second.
And this is a 12 seconds video.
And at the end here also we have 12 seconds.
So we notice that the frames of the video are equal to the frames of the composition itself.
So we have here around 300 frames.
I want to draw your attention to the fact that Moore is distorting time making your video a speedier
or slower depending on your needs and it has some nice effect that I will go to eFax and present go
to time and have time warp and take it and drag and drop it on the layer.
Now timewarp is a somehow develop and complicated effects all we want to do is to work with the motion
blur and speed here.
Or source of frame so we will do.
This lecture will be about speed.
The next election will be about source frame so I will work with speed as soon as I put the effect timewarp
the speed dropped to 50 percent.
If we play our movie here we are not is that the movement is at 50 percent or something like this.
OK so let's put this bit for example at one hundred.
So that isn't a normal speed it's 100.
That's pretty cool but what I can do is do keyframe the speed here.
I will come to the later press you get to see my keyframe over here as go to have a second something
like this and the keyframe Again the speed and make it let's say 500.
Now look what happens.
Start slow at 50 and gradually it goes to 500.
That's very beautiful what I want to do here is to change to hold keyframes because it will stay 50.
Then it moved to 100 or 500 southerly and you can see the difference.
So it starts and moves very fast.
Now I wanted to run at the end and show you what happens.
Not is that the speed was 50 here.
That's pretty cool.
It used several frames or hundreds of frames or 50 frames from the video clip.
When the speed came to 500 It also used all the frames that are available and suddenly it has normal
frames.
You know it's becoming just still because there are no more frames to move.
So actually if you want to use timewarp professionally Maybe you should the movie much longer than what
you need.
Sometimes it works and most of the time it doesn't work because you have an action movie something like
this.
So we bumped up the speed to 500 what we can do is coming here.
We can keyframe again here you are and take down the speed here to let's say 20 only and let's look
at our movie now.
We have a nice one speed goes up and speed goes down and we still have few frames until it will stop
let's take six seconds that will be OK and we can trim the work area here.
Now in this year if I move the keyframes I make this one hour run out of frames here are video frames
here.
Fine so I'll put this one back.
I still have some flames.
Two movies.
Let's put some emotion here.
Enable motion blur.
And I find this very interesting.
I would like you to look at the bulbs and also look at the background what's happening.
Let's play our movie.
It comes in and when the speed goes up we have a motion blur of five samples on the bulbs you will find
that five samples for certain frames which will create the motion blur.
That's pretty neat and pretty cool now.
OK.
So this is about the time warp speed.
You can make the speed the way you want.
Let's return them to be frames.
We go to keyframe interpellation I make them all busy here.
OK.
Here you are.
Now the speed is incrementing to get to 500 and then it stays to five and start dropping down.
Let's see here the effect goes up we needed to Aranda completely.
Now we can see it in real time.
It's quite interesting how we can play with the speed of a video using its own frames.
Be careful we are not spinning it.
So there are frames here that are you know moving faster or the sequence of the frames is much speedier.
So maybe here you are moving at.
I don't know 120 frames per second.
So this is Tamwar and it's quite easy to use it in this context.
So now just imagine what you can do what more can you do.
So I'm making it here pretty simple for you to understand how to use the time or unamusing just speed
and the Enable motion blur.
Of course the other Palamedes is that we have here are pretty complicated I would say for time games
in this section.
Later on we will see how to use them all as effects in aftereffects.
Thanks very much for listening for this lecture.
Now pick up a video that you have maybe while you were having your dinner and speed up and slow down
how you're having your dinner and the speed of you're there already or dance with your girlfriend or
you not driving your own car or something like this.
So go should some movies come back to after effects and play with them or go get some movies from Pixar
Bay or anywhere else and come and play with them here to be able to create anything you want.
It might seem very simple to you.
It is simple to use it I don't want to complicate it but actually the applications are so many.
See you in the next lecture.
