Guys and when it comes to time warp time wrote is a very nice effect that will allow you to play it
with the speed of a video or even the motion graphics composition using the frames.
You can speed up or slow down the video and even keyframe the time.
Now if you want to follow along with me please open the damn games video dash start that.
AP OK I'm opening the final one so you get the final results within this project.
Is open time warp speed.
I would double click on it.
It's open here.
It has a video.
This is the cards video and the video is to video by 720 25 frames per second and it's one minute long.
Let's go to the frames here.
Our control click or comment click on the map and you notice that it is has changed to number of frames.
So I have now 1500 frames 25 frames per second.
Let's go back to time.
It's easier to work with time so we play with animation.
That's what's happening with the films.
Let's go to the empty set and go down to time.
OK.
And then you have a time warp.
This is the effect you want to apply and work on it.
So I click on black and drop it on the video over here.
Now the timewarp might seem to do a very complicated effect.
Actually it's very easy to use.
The only thing that is hard to work with is the kuning here.
But the tuning is only related to pixel motion.
Now the method here is said to be in motion.
Click on it and you not Schaaf whole frames mix and pixel motion in the previous lecture.
We worked on the frames per second for the footage and when put it in the top we set the blending just
over here and we had three options.
If you remember when you don't set any switch it's the whole frames.
Then you have the pre-mixed.
Remember when it was ghosting and you have the pixel motion which will give you almost a perfect blending
of frames in after effect.
Now for simplicity here let's put it at tall frames and actually it would run fast when you put it on
whole frames not as the tuning had disappeared.
There is nothing to choose now.
So let's throw up the chewing we are left with the motion blurred and the source claps.
I invite you to come and play with it.
It has its effect.
I don't know it's up to you.
So what's this effect is all about.
First of all you have a just a time by speed or by source frame source frame meaning the frames of the
video itself.
Speed now is just interpretation of reframes is going to use the frames and pack them in a certain way
frames per second.
So you can get the result that you're looking for.
According to the speed as soon as you apply this effect you'll notice the speed went to 50 this value
here is not really frames per second or anything just a percentage of the number of frames you are going
to use.
At 50 you are using 50 percent of the frames.
So you are swallowing down a DVD.
If you take it at 100 it will be 100 percent of the frames and you will be running normally.
Let's come over here and let's test our video.
First of all at a 100 now if I play you not this just the normal speed by the way I took the resolution
to have here.
So it can render very fast.
Let's go back to 50.
And let's go back to the beginning.
Let's play it.
And you know the speed has been hacked.
It's almost 50 percent.
Now let's go back to the beginning again.
Stop it and let's put the speed at 300 and you play out if you do at 300.
It means you have sped up the video three times more.
It has used also three times more frames within the time lapse.
So for one second it was using 25 frames per second.
Now it's 300 is using 75 frames per second and independent of the composition frames per second doesn't
matter.
Let's turn now to 2000.
So actually now you are spitting up 20 times.
If you play it now you're not it became quite speedy for some time.
And here you are.
When you come over here.
OK.
Sometimes here you will notice that it's stopped playing just at the stable position.
So what happened here well actually this guy ran out of frames.
OK.
It can't come over here and this is the last frame he has at two thousand frames or 30 times the speed.
So actually you are at three seconds.
If you make your calculation here used three seconds times 20 times 25 frames per second.
So actually exhausted the 1500 frames which is the total of the video if you remember we came over here.
Go to frames.
This was what.
Fifteen hundred.
So at this time you have exhausted the frames you don't have any more frames and after the fact is that
ARE YOU OK.
No I don't have any more frames.
Do something.
Actually there's very little to do but that's why I chose a video that is one minute long.
Let's go back to the effect.
And play around with the keyframe you can keyframe the speedier.
Let's give them the speech first at 50.
OK.
Now the gaming really starts and then press on the stopwatch so you can get the keyframe come to the
later.
But as you and I keyframes it over here let's go down in time.
I would zoom in so I can see seconds come after 4 seconds for example and how your speed to 500 then
let's come to eight seconds.
And take down the speed to 10.
I'm just playing just to show you.
And then let's go up here and take down the speed to 3000 and then let's go down in time.
I'm sorry there are no more frames here.
If you notice but nevertheless that's plate you start here and speeding up and now swirling down.
Then the speed up and here you know not is this keyframes are linear keyframes so is stretching slowly
slowly the next keyframes speed.
You can do here to have a nice result if you like is to tackle the keyframes to hold keyframes.
So the speed is constant.
Then it jumps immediately to.
In this case 500 then it jumps immediately.
In this case to 10 and here you are at the end.
OK.
It will be 3000.
And we don't have much many frames.
Let's play it.
Now the speed
high speed
and even less speed and it's trending very nice.
I hope you kept your eye on the playing of from Iran if you have a threat here it depends.
You're not playing real time.
So there's no point to look at the video wait for it to render 100 percent.
So actually this is about the time warp speed.
Thank you very much for listening.
I will see you in the next lecture.
