Come to this story and the challenge and the challenge I asked you to use this video to replace the
window here by another video which is this one now replacing with a video is the same as using a play
composition.
You put a solid and you are replaced.
Now let's see the problems that we will have with this video.
First of all eristic the habit to drag and drop to create your composition because now everything is
in scale.
The cup is the same size as the video and you don't have any problems.
I will start a track camera.
Click on it it will start analyzing.
This is a short video of six seconds.
Also is a simple one but you will be amazed how many arrows we gonna have.
I hope you worked on it.
I hope you found the arrows and I hope you asked me a lot of questions that is already finishing pretty
speedy this time.
It has the king fixed angle of view and if you look at the advance here it does take in other DECT fun.
It is solving the camera.
Now we give it some time and get back to you.
Oh it's already done now.
Not as soon as I pointed.
I have a message says no.
That's from a crackpot by Ban assault.
So actually it didn't take it as a tripod Paran just took it as a normal camera and is not really working
very fine with us here.
We don't want to see the arrows so what.
What is this error here.
We can't figure it out.
You can find the computation about it but it means there is no depth.
There is no zoom and it cannot resolve how the camera is moving mainly on this spot where there is only
the word fun.
How do you solve this problem.
You know I've read it so this probably can work.
But better to solve that.
Let's go to other the DECT and we take mostly flat as seen.
And actually this is a flat.
It we click and it will solve the camera again and see the results that will appear.
Now it has finished this point and it seems that the error message has disappeared or in fact it's not
an error or it's just an indication that we didn't have that.
So here we are we are quite cool we have our plans here we can work with them and so on.
Let's place it and zoom in and adding a video here is just like adding a solid layer and replacing the
story.
Let's face it let's make the target size a bit bigger and not just what's happening we need even bigger.
And here you are so I need something extremely flat for the window.
This seems quite OK.
You can choose anything else you want.
No problem.
And right click and say create solid and Kamila at the same time.
So really typically this is how you will work after you have not understood everything.
Now the first thing I want to do is to go back to Xun and preview and see exactly.
Is this solid is really working for this kind of tracking.
It seems it's OK is moving very nicely with the window.
OK I don't know if it's moving with the background or the flat window but of course it's moving with
the background color so that's not bad at all.
What we can do is immediately come to our saling movie here and press on it or choose our layer press
alt and just drop it in.
Here we are.
We have our movie just over here so that's pretty small now we need to scale it and work on it.
OK that's one way to what you could have done even better.
I would scale it up press shift to scale it up OK it's not working so I need to adjust it.
That's not bad like this code.
So of course I need now to get corner when I put it in.
And that's exactly how I can fit it if it fits nicely.
Is done here and here it is OK I have some white Here I'll try to fix it.
Now we're not doing an extremely proud job on stories like this.
You don't have to be a bit you know it's OK.
If I were doing a professional project this would not be allowed and not just how the light is coming
but for the purpose of doing an exact size on camera tracking this will do fine so I put my leg up there
and I have now one movie in another I remove the sound and then come to preview and preview exactly
what is happening.
Well actually it seems it's working fine not this.
There is some white that is appearing good.
And I really don't like the light here but it's ok.
It's working for the purpose of an exact size.
Now how did you benefit from this exercise.
First you notice that sometimes you have to use the advanced option here and find out OK which one can
I use to remove the messages if there are any.
Also instead of using most D-flat seen you could have used also variable zoom at your free time please
try or pan or typical and see the results that you will get.
I hope this challenge was useful for you.
I know it's simple.
It's important that you start with simple things and the standardly how it's working how the corner
pin can be useful to you and try to do as many as simple things possible before you go too complicated.
And you know things that already you need to use maybe a busy warp or something like this.
Paul thanks very much for listening.
I'll see you in the next election.
