Guys.
And welcome to this new lecture where we are going to discuss the difference between tracking camera
and tracking motion.
Now we have used this video before.
If you review it you know there's something very important that the synergy or the scene is not moving
at all.
The camera is somehow stable and then it is only one element here or one object that is moving.
Just make sense here to use truck motion.
I will be tracking the motion of this object.
It's like having this guy who's shooting a movie and he is not really moving the camera.
The camera is on the tripod.
It is fixed is not moving at all.
And then inside he can have the boat for example moving only and that is when you lose track of motion
and it's very important.
Let's take the example of the overview.
If you play this video you notice that nothing is moving.
Of course you don't expect the houses to move.
What's really moving is the camera.
And of course this is you know already this is a drone that's flying over the area.
So actually the camera only is moving and nothing is moving within the scene itself.
In that case you will use a camera and that's very easy to distinguish.
For example if we take our video here the one we are going to work on is here that really.
Let's play it.
You notice here that the camera only is moving and the movement of the camera here is just zoom in with
the pan on the right bit.
So in that case I could use a camera tracking and that will be much better than using motion tracking
because Actually nothing is moving here.
So in concept when you have something moving an animal moving with the video and the scenery is not
moving at all like this example then you would use it to track motion.
But if you have the camera that is moving and not elements nothing is moving within the video then you
will lose track a camera and then you can look at all the points here in this example we want to track
the camera or the movement and the camera.
And that has other elements such as solid layers and text is exactly what happened with the truck camera.
So please always try to ask yourself the question should I use a tracking camera or a tracking motion.
If you're tracking a single element that is moving and the scenery is not moving at all then you will
lose track motion if your Cinelli is moving.
And the elements inside are not moving at all.
Then you will use Track camera.
Now it could be that both of them are moving.
The camera is burning.
And there are some elements that are moving in within the video.
Then you can decide which one will be more feasible for you.
And by studying truck camera you will notice the difference between truck and track motion and you will
be able to decide even better which one to use.
Thanks very much for listening.
I will see you in the next election.
