1
00:00:00,920 --> 00:00:04,220
From our work flow we are going to start with that point.

2
00:00:04,310 --> 00:00:06,440
Step one is applying the effect.

3
00:00:06,530 --> 00:00:13,010
And of course creating the track points seeing exactly how it works and the different options that you

4
00:00:13,010 --> 00:00:16,550
might have if you want to follow along with me.

5
00:00:16,560 --> 00:00:18,330
Please open the project file.

6
00:00:18,470 --> 00:00:25,650
Commit at tracking dot AP within this project please open Kamelot tracking Althouse as DoubleClick on

7
00:00:25,650 --> 00:00:26,130
it.

8
00:00:26,130 --> 00:00:29,160
We only have the video of the old house.

9
00:00:29,370 --> 00:00:34,920
That's first of all look at the video you'll notice that the House is not moving and that we have a

10
00:00:34,920 --> 00:00:39,260
camera that is zooming in somehow and it has a certain motion.

11
00:00:39,430 --> 00:00:42,750
OK it's not going straight just moving at a certain angle.

12
00:00:45,090 --> 00:00:51,420
So now let's use 3-D come out tracking to track the camera movement that has been used to shoot this

13
00:00:51,420 --> 00:00:52,490
video.

14
00:00:52,500 --> 00:00:54,050
You have two options here.

15
00:00:54,210 --> 00:01:00,830
You can come to the tracker and click on track camera or you can come to ethics and preset and go to

16
00:01:00,840 --> 00:01:01,680
perspective.

17
00:01:01,890 --> 00:01:04,670
And you know as you have 3-D camera tracked.

18
00:01:04,830 --> 00:01:07,750
Let's use the camera from the tracker here.

19
00:01:07,890 --> 00:01:12,990
Click on it you immediately start analyzing in the background.

20
00:01:13,020 --> 00:01:19,820
Step one of two and the effect 3-D camera tracker has been applied to the video.

21
00:01:20,350 --> 00:01:21,960
You have several options here.

22
00:01:22,170 --> 00:01:26,690
You can cancel and you have the shot type down here.

23
00:01:26,860 --> 00:01:30,670
You'll notice you have two main options fixed angle of view.

24
00:01:30,720 --> 00:01:36,500
That's the one that's working on and valuables should have been interesting if used the valuable zoom

25
00:01:36,510 --> 00:01:40,520
here in our video because we had a lot of zoom here.

26
00:01:40,560 --> 00:01:45,340
It could give you better result but we see that later you have other options also.

27
00:01:45,360 --> 00:01:52,900
And the advance we will work on it now is starting to solving the camera solving the camera.

28
00:01:52,920 --> 00:01:58,770
It means it's trying to find out what kind of camera it's going to create for you and how it's going

29
00:01:58,770 --> 00:02:02,130
to create the motion of the camera actually.

30
00:02:02,250 --> 00:02:08,130
It will not create the camera it will just study how a camera can be created.

31
00:02:08,820 --> 00:02:15,030
As soon as it finishes you're not is that good come into option has a built if you click on it it will

32
00:02:15,030 --> 00:02:16,260
create a camera.

33
00:02:16,290 --> 00:02:17,280
I will do that.

34
00:02:17,280 --> 00:02:18,180
If you are.

35
00:02:18,190 --> 00:02:18,920
You got this.

36
00:02:18,960 --> 00:02:21,310
There is the 3-D camera tracker.

37
00:02:21,480 --> 00:02:23,980
That's a camera that has been created.

38
00:02:24,210 --> 00:02:29,010
And if you press you position and orientation is being framed.

39
00:02:29,130 --> 00:02:31,150
So emotion has been created.

40
00:02:31,170 --> 00:02:32,670
Let's see this motion.

41
00:02:32,670 --> 00:02:39,320
If you come to view these until of course you know that from the 3D section you know the camera is over

42
00:02:39,320 --> 00:02:47,580
here and the position and orientation has being keyframe and the camera now is moving and it replicates

43
00:02:47,670 --> 00:02:52,260
exactly the movement of the camera used to shoot the video.

44
00:02:52,480 --> 00:02:59,370
Not is that the old house is not in 3-D doesn't make sense to put it in 3-D but any other layer that

45
00:02:59,370 --> 00:03:04,200
you want to use through the camera tracking will be in 3-D.

46
00:03:04,200 --> 00:03:04,510
OK.

47
00:03:04,590 --> 00:03:09,790
Let's go back to a single view and select the 3D camera truck.

48
00:03:09,870 --> 00:03:13,910
Notice how there are these Xs all over there.

49
00:03:13,980 --> 00:03:16,820
These are the track points.

50
00:03:16,820 --> 00:03:17,330
OK.

51
00:03:17,400 --> 00:03:24,870
And you are going to use these points to define certain areas or certain plane to odd objects in 3D

52
00:03:25,810 --> 00:03:29,130
or not is that there are very few on this side over here.

53
00:03:30,350 --> 00:03:37,060
Aftereffects has done its best to look at certain track points so you can use them in the 3-D tracking.

54
00:03:37,070 --> 00:03:43,850
Now there's a bit about this duckpond through you or not is that some track points will appear all along

55
00:03:43,850 --> 00:03:49,700
the video and some of them will appear and disappear and some of them will just disappear after having

56
00:03:49,700 --> 00:03:50,310
appeared.

57
00:03:50,510 --> 00:03:54,400
So actually they're not all stable at 100 percent.

58
00:03:54,440 --> 00:04:00,080
This is the effect of the tracking in some frames after the fact did not manage for example to find

59
00:04:00,200 --> 00:04:01,850
the track point over here.

60
00:04:01,850 --> 00:04:05,020
So I decided OK let me deleted or remove it.

61
00:04:05,090 --> 00:04:05,650
OK.

62
00:04:05,810 --> 00:04:07,910
You cannot this from this guy over here.

63
00:04:07,910 --> 00:04:09,230
It wasn't that.

64
00:04:09,440 --> 00:04:10,910
Then you start finding it.

65
00:04:10,940 --> 00:04:13,040
And he goes on I think the.

66
00:04:13,070 --> 00:04:15,790
And now it does appear they get.

67
00:04:15,800 --> 00:04:22,340
So these are the track points and you are going to use them to define search and plane to put your 3-D

68
00:04:22,510 --> 00:04:27,110
as later on that is that we have very few track points over here.

69
00:04:27,430 --> 00:04:29,980
Aftereffects is not taking care of this.

70
00:04:30,260 --> 00:04:36,710
We can go back to the fix and get view and change it to vibrate but resume.

71
00:04:36,840 --> 00:04:39,720
Now it has the results again for the valuable zoom.

72
00:04:39,780 --> 00:04:42,560
I notice you have the camera again.

73
00:04:42,840 --> 00:04:44,280
Let's create this camera.

74
00:04:44,610 --> 00:04:47,700
But usually you won't do that you will have only one camera.

75
00:04:47,820 --> 00:04:55,350
But in our case here we have one camera that doesn't use the zoo and another camera that uses the zoom.

76
00:04:55,350 --> 00:05:01,580
This is more precise if you like put the biggest camera OK.

77
00:05:01,860 --> 00:05:05,850
And then let's select the old house or the effect itself.

78
00:05:06,240 --> 00:05:07,990
And you know this was the new camera.

79
00:05:08,040 --> 00:05:11,460
You have much more track points around here.

80
00:05:11,790 --> 00:05:16,910
It means after effects has taken care more of the zoom and created more track points.

81
00:05:16,910 --> 00:05:22,620
If you want by now you have applied the effect and created the track points.

82
00:05:22,890 --> 00:05:24,930
You know there's this circle moving around.

83
00:05:24,970 --> 00:05:27,850
OK jumping out of this circle.

84
00:05:27,910 --> 00:05:35,520
We'll use the track points to define a 3D plane on which you can attach different kind of 3-D layers.

85
00:05:35,550 --> 00:05:38,280
And this is what we are going to do in the next lecture.

86
00:05:38,340 --> 00:05:39,000
Thank you.

87
00:05:39,000 --> 00:05:39,840
I will see you then.
