Hi Guys welcome to motion tracking.
Now in this lecture we want to look at Raqi motion and we are going to work on perspective.
Gardner Because now we have a video clip here if we want to preview it now not um on half resolution
here.
I put it on auto to save some time so it can render all the movie and the view here is half of its final
quality I can put on adaptive quality.
But this is OK now it's rendering the whole movie by changing here to auto or full or quarter.
Then you will be able to save on memory and increase the speed of rendering.
Now we want to track something you see.
This is a scene of a living room and on the TV here what's happening is some cartoons we don't want
these cartoons.
We want to put another movie.
So how do we change the content of this movie.
We are going to go to Cracker and we are going to select our leader and say truck motion I will come
to transform here and choose perspective color pin and that will give us four corners to track and then
we can replace them with any video or image or whatever we want there.
I would click on it and I have the four corners I would go back to the beginning.
OK you don't want to start doing this in the middle.
And I will zoom in a bit.
Now I have to adjust the four corners to the corners of the TV for example here in either case the first
corner and tried to put as much as possible on the corner of the TV here will do for example take the
other corner and just pull it over here.
And maybe not want to go back.
Yes.
And we take the third corner from here and put it over here.
That would do and take the last quarter and put it on the corner of the TV.
Now I'm showing you something very simple something that's practical for you to replicate.
We are starting to demonstrate how the collars will work so I'm not going to do something very fancy
for you to get confused and give up.
No there's something very easy and you want to go out and even take a shot of all your own living room.
You know this is what I have done here I took a shot of the living room of my children.
It's very simple video.
The video is not even good quality It doesn't really matter.
What matters is to train on the corner and to train on the track.
Fun now that you put the tracking we want of course to analyze.
Let's click on and our lives are not as if the points are going to stay in the corners of the TV and
they're not going to start jumping around.
It seems everything is working very fine.
You notice how easy is it is not hard and it's very simple of course.
If you go watching videos we're on YouTube where the guys are showing off their skills.
You might be intimidated.
But actually here it's very easy.
Here you are.
It's about to finish.
Great.
Now it has tracked everything it has analyzed.
I want to bring another movie let's say we don't want this one.
We want to take maybe the movie of the boat but this is a short movie.
So let's go and bring another movie import file and I have a movie in mind that will make it interesting
for the kids to watch which is the version we can take this movie for example and they just put it here.
That's a nice video clip.
So we brought it in.
And we are going to drop it under or above the scene when I come to source I will choose my layer and
then go to the death panel.
And here we have them all right.
And we say any target now.
And we're going to dig version that.
And before and click OK I would click on apply to apply and it goes back to the composition and not
is what's happening here.
The adversion video has an effect that is corner pin if you can to kind of pin here you will see them
for the four corners so it has determined the four corners and also it has a position keyframes.
So it has put the keyframe for the all the corners and also has given for the position.
Now it seems like it's not working.
That's because the version movie that is already cropped somehow is under the main layer.
I will take it and put it above.
Here you are now you notice that it has changed.
If you come to the beginning and you have your preview which is the new movie on the TV and this is
how you work on it it's not difficult.
It's pretty easy and I encourage you to come and do some test.
Of course this lecture is not that sophisticated for the purpose to show you how easy it is going to
be for you to use the four corner pin and to replay certain areas of your movie by other movies or by
other pictures or images whatever you want or even some other graphics that you can put there.
I hope this was useful and you just had to aftereffects open it and create your own videos or impart
some videos and start using the Connard bin and the tracking.
You create something unusual in your videos.
I see you in the next election.
