00:00:01,450 --> 00:00:04,100
Hi guys and welcome come to perspective.

2
00:00:04,170 --> 00:00:12,000
I've been tracking which will help you to track certain areas using the track motion and it's very interesting.

3
00:00:12,330 --> 00:00:18,830
Our mission in this lecture is to track the green area here on the Hindhead form.

4
00:00:18,860 --> 00:00:21,830
It really doesn't matter the movement of the phone whatever it is.

5
00:00:21,900 --> 00:00:23,430
We'll track it very nicely.

6
00:00:23,760 --> 00:00:29,290
Now some of you might be wondering why am I using the green skanking here or the king.

7
00:00:29,580 --> 00:00:34,080
Well if you're not very well there is no foreground on this video.

8
00:00:34,260 --> 00:00:40,080
You will use the king to remove a green screen when there is a foreground so you remove the background

9
00:00:40,080 --> 00:00:42,340
that's supposed to be green and keep the foreground.

10
00:00:42,570 --> 00:00:44,690
But over here there is no foreground.

11
00:00:44,840 --> 00:00:47,260
There is nothing in front of the green screen.

12
00:00:47,370 --> 00:00:49,810
So obviously keying is nonsense.

13
00:00:50,300 --> 00:00:55,220
You will lose track motion with the perspective can of beans and it will do the job.

14
00:00:55,900 --> 00:01:04,090
Start I would select the default layer of course and then click on track motion a single point has been

15
00:01:04,300 --> 00:01:10,030
created for you if you come to the track type here it is transform.

16
00:01:10,100 --> 00:01:13,660
I want you to click on it and go select a perspective corner.

17
00:01:13,880 --> 00:01:17,880
Not will because this guy there is nothing parallel here.

18
00:01:18,080 --> 00:01:21,110
So you go to perspective born of pain.

19
00:01:21,380 --> 00:01:26,920
Now you have a four track bounce created for you if you come to the layer here in the tracker you'll

20
00:01:26,960 --> 00:01:34,040
see four trackballs is born has exactly the same properties as a normal duckpond nothing different at

21
00:01:34,040 --> 00:01:34,420
all.

22
00:01:35,630 --> 00:01:43,100
So our mission now is to position the track points on the corner of the area we want to track.

23
00:01:43,220 --> 00:01:47,660
And then of course analyze and then hit the target as simple as this.

24
00:01:47,660 --> 00:01:53,810
So let's start by positioning the track points actually positioning the track points is the key of the

25
00:01:53,810 --> 00:01:55,990
success of this maneuver.

26
00:01:56,000 --> 00:01:59,560
If you like I will zoom in just a bit.

27
00:01:59,720 --> 00:02:00,450
OK.

28
00:02:00,770 --> 00:02:03,450
And take the first duckpond selected.

29
00:02:03,560 --> 00:02:08,840
Click on it and just right now there are a few things that you need to pay attention to.

30
00:02:09,020 --> 00:02:15,530
You're not only paying attention to the point of position but also you're paying attention to the line

31
00:02:15,530 --> 00:02:20,000
itself is the line really covering the area that you want.

32
00:02:20,000 --> 00:02:22,040
So let's take the second pin here.

33
00:02:22,460 --> 00:02:24,810
Click inside and drag and just put it over here.

34
00:02:25,010 --> 00:02:30,310
Being careful to make sure that the line is covering the area like this is not like this.

35
00:02:30,330 --> 00:02:35,370
It is and I bring it as neat as the green area as possible.

36
00:02:36,380 --> 00:02:41,390
Now let's position take point forward and that's what's going to happen if you click and drag the track

37
00:02:41,390 --> 00:02:47,540
point is not moving any more because it has been stopped with the line you know connecting three point

38
00:02:47,540 --> 00:02:50,240
one track three and three point four.

39
00:02:50,270 --> 00:02:54,980
So maybe First we try to adjust the track monthly just come over here.

40
00:02:56,450 --> 00:03:04,740
I just put it in the corner making sure that the line above here is ok making sure that the line here

41
00:03:04,980 --> 00:03:07,020
is really covering the area we want.

42
00:03:07,160 --> 00:03:09,240
And let's go to three point.

43
00:03:09,330 --> 00:03:10,660
As simple as this.

44
00:03:10,830 --> 00:03:13,590
Click on black and just put it over here.

45
00:03:14,010 --> 00:03:20,820
Now you zoom out and what you want to make sure that the lines are covering the area that you want to

46
00:03:20,820 --> 00:03:21,450
track.

47
00:03:21,660 --> 00:03:26,200
So they added an area that will be trucked through that points.

48
00:03:26,310 --> 00:03:27,850
Simple.

49
00:03:27,970 --> 00:03:28,730
This is done.

50
00:03:28,810 --> 00:03:34,640
All you have to do is to press on and allies forward.

51
00:03:34,670 --> 00:03:40,700
Now depending on the speed of your computer this can go very fast or very slow but you need to watch

52
00:03:40,700 --> 00:03:40,890
it.

53
00:03:40,910 --> 00:03:46,690
You can AJ OK go make coffee come back because if there is a problem you want to see the problem now.

54
00:03:46,850 --> 00:03:51,960
You don't want to start discovering the problems after you have you know completed the track.

55
00:03:51,980 --> 00:03:53,750
You might want to stop it now.

56
00:03:53,930 --> 00:03:58,550
For me I know it's going to go very right and I would be watching it but that would speed up the video

57
00:03:58,850 --> 00:04:00,620
and get back to you when it has complete

58
00:04:04,560 --> 00:04:10,630
OK so it has finished the tracking and not is there are thousands of keyframes here.

59
00:04:10,690 --> 00:04:14,860
Let's first of all enjoy ourselves and put the video and see if we have done a good job.

60
00:04:14,910 --> 00:04:16,660
Then we'll come back to the letter here.

61
00:04:16,810 --> 00:04:19,680
Say exactly what happened in the letter.

62
00:04:19,780 --> 00:04:27,300
I would take the version which is a nice airplane here and drop it inside the composition you know is

63
00:04:27,310 --> 00:04:32,620
that the version video is smaller than the main video or the main video was then ETP.

64
00:04:32,620 --> 00:04:34,330
This one is 720.

65
00:04:34,580 --> 00:04:34,900
OK.

66
00:04:34,900 --> 00:04:37,850
Let's see what happens after all the phone is not that big.

67
00:04:38,780 --> 00:04:44,590
I would come back to the phone and of course I have to come back to the lead because while dropping

68
00:04:44,600 --> 00:04:47,260
the version it has moved to the current position.

69
00:04:47,670 --> 00:04:53,140
And I would say that we have only version and we click OK.

70
00:04:53,410 --> 00:04:55,570
It's not going to ask you for X Y position.

71
00:04:55,610 --> 00:05:05,890
Everything is set for the let's go and apply and see our work give it the second and play I press F

72
00:05:05,890 --> 00:05:07,600
2 and play.

73
00:05:07,750 --> 00:05:14,790
It has tracked it put the video using a certain effect and it's done at 100 percent.

74
00:05:14,890 --> 00:05:16,290
Political guys right.

75
00:05:17,570 --> 00:05:22,120
Let's go now and explain a bit what happened in the inversion layer.

76
00:05:22,130 --> 00:05:27,830
If you click on it you'll notice that there is the corner in fact that has been applied.

77
00:05:27,920 --> 00:05:34,450
You can come to ever Templi set and look for the corner pin it will actually help you to distort a video

78
00:05:34,460 --> 00:05:41,870
or whatever you like using its four corners the upper left upper right lower left and or right the four

79
00:05:41,870 --> 00:05:43,100
corners over here.

80
00:05:43,300 --> 00:05:48,300
And that is that after effects has taken keyframes for every track point.

81
00:05:48,460 --> 00:05:53,630
OK if you're not as blackpoint one here has keyframes for the attach point.

82
00:05:53,630 --> 00:05:55,250
It has taken blackpoint one.

83
00:05:55,280 --> 00:06:00,710
If it is this corner and put it on the upper left as simple as this.

84
00:06:00,740 --> 00:06:07,520
So it used in effect and took all the keyframes from the track points here and put them on the corners

85
00:06:07,610 --> 00:06:09,230
of the corner pin.

86
00:06:09,290 --> 00:06:10,590
This is the corner in here.

87
00:06:10,640 --> 00:06:15,870
I can move it by the way I'm just destroying the wart but just to show you how the current is working

88
00:06:16,230 --> 00:06:18,940
Hey dealer fine.

89
00:06:19,080 --> 00:06:22,780
I will undo this and the other one again.

90
00:06:23,200 --> 00:06:24,430
So now you have done the job.

91
00:06:24,460 --> 00:06:26,700
It is so easy to convert.

92
00:06:26,710 --> 00:06:28,830
In fact I'd encourage you to come and use it.

93
00:06:28,840 --> 00:06:37,550
Even that is one that is much better from CC and you have your animation pretty nicely done.

94
00:06:37,930 --> 00:06:44,950
OK guys if there isn't anything that is not clear here because it seems very simple and it is exactly

95
00:06:45,250 --> 00:06:50,530
please ask your questions in the challenge activity that will have to do the same work for a different

96
00:06:50,530 --> 00:06:54,620
kind of form and a different kind of position and much higher movement.

97
00:06:54,820 --> 00:06:56,470
Thank you very much for listening.

98
00:06:56,470 --> 00:06:58,100
I will see you in the next lecture.
