00:00:00,420 --> 00:00:00,860

Guys.



2

00:00:00,870 --> 00:00:06,330

And welcome to this new lecture where we are going to discuss the difference between tracking camera



3

00:00:06,390 --> 00:00:08,120

and tracking motion.



4

00:00:08,160 --> 00:00:09,900

Now we have used this video before.



5

00:00:09,960 --> 00:00:17,070

If you review it you know there's something very important that the synergy or the scene is not moving



6

00:00:17,130 --> 00:00:18,000

at all.



7

00:00:18,000 --> 00:00:24,870

The camera is somehow stable and then it is only one element here or one object that is moving.



8

00:00:25,050 --> 00:00:28,100

Just make sense here to use truck motion.



9

00:00:28,290 --> 00:00:31,330

I will be tracking the motion of this object.



10

00:00:31,380 --> 00:00:37,670

It's like having this guy who's shooting a movie and he is not really moving the camera.



11

00:00:37,680 --> 00:00:39,920

The camera is on the tripod.



12

00:00:40,000 --> 00:00:42,720

It is fixed is not moving at all.



13

00:00:42,900 --> 00:00:52,230

And then inside he can have the boat for example moving only and that is when you lose track of motion



14

00:00:52,320 --> 00:00:54,240

and it's very important.



15

00:00:54,350 --> 00:00:56,530

Let's take the example of the overview.



16

00:00:56,630 --> 00:01:00,380

If you play this video you notice that nothing is moving.



17

00:01:00,380 --> 00:01:03,530

Of course you don't expect the houses to move.



18

00:01:03,530 --> 00:01:06,260

What's really moving is the camera.



19

00:01:06,260 --> 00:01:11,060

And of course this is you know already this is a drone that's flying over the area.



20

00:01:11,330 --> 00:01:19,420

So actually the camera only is moving and nothing is moving within the scene itself.



21

00:01:19,460 --> 00:01:24,580

In that case you will use a camera and that's very easy to distinguish.



22

00:01:24,740 --> 00:01:30,750

For example if we take our video here the one we are going to work on is here that really.



23

00:01:30,770 --> 00:01:32,270

Let's play it.



24

00:01:32,270 --> 00:01:38,410

You notice here that the camera only is moving and the movement of the camera here is just zoom in with



25

00:01:38,410 --> 00:01:40,780

the pan on the right bit.



26

00:01:40,820 --> 00:01:47,450

So in that case I could use a camera tracking and that will be much better than using motion tracking



27

00:01:47,450 --> 00:01:49,630

because Actually nothing is moving here.



28

00:01:49,790 --> 00:01:57,980

So in concept when you have something moving an animal moving with the video and the scenery is not



29

00:01:57,980 --> 00:02:02,090

moving at all like this example then you would use it to track motion.



30

00:02:02,180 --> 00:02:10,940

But if you have the camera that is moving and not elements nothing is moving within the video then you



31

00:02:10,940 --> 00:02:17,660

will lose track a camera and then you can look at all the points here in this example we want to track



32

00:02:17,660 --> 00:02:19,640

the camera or the movement and the camera.



33

00:02:19,640 --> 00:02:26,750

And that has other elements such as solid layers and text is exactly what happened with the truck camera.



34

00:02:26,990 --> 00:02:34,380

So please always try to ask yourself the question should I use a tracking camera or a tracking motion.



35

00:02:34,430 --> 00:02:40,280

If you're tracking a single element that is moving and the scenery is not moving at all then you will



36

00:02:40,280 --> 00:02:43,820

lose track motion if your Cinelli is moving.



37

00:02:43,850 --> 00:02:46,730

And the elements inside are not moving at all.



38

00:02:46,880 --> 00:02:49,770

Then you will use Track camera.



39

00:02:49,820 --> 00:02:52,550

Now it could be that both of them are moving.



40

00:02:52,580 --> 00:02:53,880

The camera is burning.



41

00:02:53,900 --> 00:02:57,590

And there are some elements that are moving in within the video.



42

00:02:57,590 --> 00:03:00,950

Then you can decide which one will be more feasible for you.



43

00:03:01,190 --> 00:03:06,440

And by studying truck camera you will notice the difference between truck and track motion and you will



44

00:03:06,440 --> 00:03:09,350

be able to decide even better which one to use.



45

00:03:09,350 --> 00:03:10,730

Thanks very much for listening.



46

00:03:10,760 --> 00:03:12,080

I will see you in the next election.
